Description

201219465 6. Technical Field of the Invention The present invention relates to a black film, a substrate with a black film containing the black film, an image display device, a black resin composition, and a black material dispersion. [Prior Art] As described in Patent Document 1, for example, as described in Patent Document 1, metal materials such as black, titanium black (titanium oxide or nitrogen oxide), iron oxide, chromium, silver fine particles, or the like are known. material. These black materials are also used in plasma display panels (PDP), liquid crystal displays (LCD), and organic electroluminescence (EL) displays in addition to black light-shielding films, black light-shielding glass, black paper, black cloth, and black ink. A black matrix material, a black sealing material, a black mask material or the like of the display element is used as a material for imparting black or light blocking properties. In the above, a black matrix or a black stripe (hereinafter simply referred to as a "black matrix") for a liquid crystal display element is used to prevent light leakage between pixels in a liquid crystal display element caused by a driving electrode or the like. Suppresses blurring or blurring of images. Moreover, these are generally stripe-like or lattice-like light-shielding materials formed on a transparent substrate such as glass or plastic sheet which is paired with a TFT (Thin Film Transistor) element substrate by photolithography. The pattern. In the case where the black matrix or the like is formed using a film of chromium oxide or the like, a black film is usually formed by dispersing the black material in a photosensitive resin component, and then a photo-lithography method is used to form a tree-like component. Pattern, and made 157917.doc 201219465 as a resin black matrix. Here, the black matrix for the conventional liquid crystal display element is formed on a transparent substrate such as a glass or a plastic sheet which is paired with the TFT element substrate. Recently, in order to cope with further high definition and high brightness in a color liquid crystal display, it has been disclosed that in an active matrix type liquid crystal display, a color filter is disposed on an array on a TFT element substrate side in a color filter mode (COA ( Color Filter On Array) or black matrix on the TFT substrate element side (B〇A (Black MatHx On Array) method) ^ according to these methods, and forming a black matrix in color Compared with the case of the filter side, since the positional alignment margin with the active element side is not required, the aperture ratio can be increased, and as a result, high luminance can be achieved. Further, in order to achieve high contrast in the liquid crystal display device, it is necessary to further prevent light leakage between the liquid crystal elements of red (R), green, and blue (B), and further suppress blurring or speckle of the image, that is, liquid crystal. In the display device, 咼π degrees and 咼 contrast are obtained, and it is necessary to make the black matrix finer and have high light blocking property. In addition, the narrow angle of view that becomes a problem in the TN (Twisted Nematic) driving type liquid bb is greatly expanded.

Plane Switching, a horizontal electric field switch) is also attracting attention. On the other hand, in recent years, plasma display devices, inorganic EL devices, organic EL devices, and the like have been put into practical use as self-luminous display devices that do not require a backlight or the like. The self-luminous display devices are constructed such that they have a gas layer 157917.doc 201219465 or a light-emitting layer containing an inorganic or organic solid material between a pair of electrodes. In order to achieve high luminance in such a self-luminous type display device, a method of enlarging the light-emitting area of each of the light-emitting elements itself can be considered. In order to achieve high contrast, it is important to prevent color mixing by preventing light leakage or mutual interference between R, G, and 发光 light-emitting elements, and to suppress blurring or speckle of an image. Further, in order to achieve this, it is necessary to form a light-shielding wall by blocking the partition wall or the separation layer between the respective light-emitting elements, and to make the light-shielding wall finer and have a light-shielding property. Further, in such a self-luminous display device, as a display quality, improvement in contrast has become a major issue. In other words, there is a problem that external light is incident on the display surface, and therefore, the display of light from the light-emitting layer is known. As a result, good display quality cannot be obtained. This reflection is mainly caused by a partition wall or a separation layer between the respective pixels, and a wiring for driving the light-emitting elements provided in the portion. Therefore, the more effective enthalpy is not only to shield the partition wall or the separation layer, but also to provide a black matrix or the like, whereby external light is not incident on the light-emitting element driving wiring. Here, in the liquid crystal display element of the COA method or the BOA system, or the self-luminous display device, the element driving wiring is brought into contact with a black matrix or the like, or the light shielding wall is provided, or the element driving wiring is directly provided on the black matrix or the light shielding wall. The structure has become mainstream. In this case, in order to prevent short-circuiting between wirings, it is necessary to use an insulating material having a volume resistivity of a certain value or more for a black matrix or the like. In the case of IPS-driven liquid crystal, if the black matrix is electrically conductive, the 157917.doc 201219465 electric field is generated in a direction different from the electric field used to drive the liquid crystal, resulting in image confusion, so it is necessary to make black The matrix is insulative. Further, in the black matrix or the like or the light-shielding wall, in order to stably operate the TFT element or the self-luminous element without causing image disorder, it is necessary to minimize the parasitic capacitance, and the like, and a lower specific dielectric constant is required. In the conventional black matrix or the like or the light shielding wall, carbon black is generally used as a black material for light shielding. Carbon black has a high light-shielding property, but has a low electric resistance value. Therefore, when it is mixed with a known component to form a black matrix or the like, or a light-shielding wall, if the light-shielding property is high, the carbon black is added to the resin component. When the amount is added, the particles of carbon black are brought into contact with each other to form a conductive path, so that the problem of insulation of the black matrix or the like or the light shielding wall cannot be maintained. In order to prevent the above problem that the insulating property of the light-shielding wall cannot be maintained, there is a method of controlling the addition amount of carbon black to maintain the insulation property without exhibiting conductivity, and by increasing the thickness of the black matrix or the height of the light-shielding wall. Improve shading. However, in this method, the optical density per 丨μη film thickness can only be obtained at most 〇.5, so in order to obtain the optical density (pass* is 2.5 or more) necessary as a black matrix, it is necessary to increase the film thickness. . Therefore, the step difference between the substrate and the black matrix or the light-shielding wall becomes large. As a result, the wiring is easily broken, or the uniformity between the liquid crystal elements or the respective light-emitting elements is deteriorated, and the unevenness in the surface of the element is increased. On the other hand, even if the insulation property can be maintained, the film has a higher specific dielectric constant than 200, which may cause image confusion. π is a method for obtaining such a problem that a black matrix or a light-shielding wall having a high light-shielding property, an insulating property, and a thickness is suppressed, and having a lower specific dielectric constant, 157917.doc 201219465. In the second document, the method of dispersing the surface of the carbon black with a diazo compound on the surface of the carbon black, thereby increasing the ratio of the carbon black 3 of the black matrix tree to improve the light-shielding property and maintaining the insulating property is disclosed. Further, 'Patent Document 3 discloses a method of coating a surface of a carbon particle with an insulator f to thereby obtain a black matrix having a high insulating property and a relatively low specific dielectric constant. Further Patent Document 4 It is disclosed that a powder of titanium oxynitride (TiOxNy: chinensis) which has a light-shielding property by using a control composition is used as a black material, and it is used in combination with a well-known oxide powder, thereby obtaining high opacity at the same time. Further, Patent Document 5 discloses a method of reducing the content of carbon black and adding an organic pigment to thereby obtain a black matrix having high light-shielding property and insulating property. Usually, the signal of the wireless remote controller (remote control) is LED (Light Emitting Diode) with a wavelength of 950 nm, and the industrial wavelength is 1064 nm. In order to prevent erroneous operation or appearance due to visible light, a cover for a member that uses a component that blocks visible light and transmits infrared rays such as near-infrared rays is generally provided for the signal source or the light-receiving element. 'Infrared transmission black film which has sufficient transparency to light having a wavelength from the near infrared ray to the infrared ray, or an infrared ray transmission filter using the infrared ray transmission black film, although it is black in appearance. Doc 201219465 In the liquid Ba panel of the next generation, it is generally considered that the c〇a method or the boa method will be a line'. However, in these methods, the black coated dry film formed on the array side is patterned. As the black matrix of the black film, it is necessary to directly align the position of the black matrix pattern with respect to the array. This position alignment uses infrared rays of ～95 〇 nm, so the reading position alignment signal is expected to make the wavelength region The black coated dry film that transmits light is used as a black matrix material. In addition, in the case of black (four) members, it is usually The optical density (〇D value: 0ptieal Denshy) is used as an index of the transmittance. When the transmittance of the film is set to T(%)', it is represented by the following formula (1): 〇D=-l〇g(T/ 1()()) (1) Further, in the case of a black matrix member, the OD value per 1 μm thickness is often used as an indicator of the light-shielding property. ▲In view of the above problem, the improvement described in Patent Documents 1 and 6 is considered. In the method of the prior black film, a metal material such as carbon black, titanium black (titanium oxide), iron oxide, chromium, and silver fine particles or an inorganic material is mainly used as the '', color material' to disperse the black materials. A black film is formed by using the material thus obtained in an organic resin or an inorganic resin, etc. In addition, an infrared (four) type filter using an organic pigment or a dye as a black material as disclosed in Patent Documents 7 and 8 is disclosed.

[Problem to be Solved by the Invention] First, the above-mentioned technique for simultaneously improving the light-shielding property and the insulating property is manufactured in the above method for improving the dispersibility of carbon black. The state in which the carbon black particles themselves are dissolved or agglomerated does not change, and therefore merely improves the dispersibility of the dazzling particles or the agglomerated particles. Therefore, especially when the amount of carbon black is increased in order to increase the degree of blackness, the presence of the melted particles or the agglomerated particles re-agglomerates, the uniformity of the characteristics of the black matrix is lowered, or partial conductivity is exhibited. The problem. Further, in this document, in order to improve the stability, a method of temporarily forming a film is disclosed in a non-liquid state, but the manufacturing process of the black matrix is complicated, and the bondability between the black matrix and the substrate is lowered. problem. Further, in the above method of coating the surface of carbon particles with an insulating material, there is also a problem that the manufacturing process of the black matrix is complicated. Further, in the document, there is no specific description of the insulating material, and it is difficult to carry out. Further, in the method of using the titanium oxynitride powder described above, there is a problem in that the oxynitride has electrical conductivity, so that the insulating property of the black matrix can be ensured by combining with the insulating oxide powder, but it can be added thereto. Forming 157917.doc 201219465 The resin composition of the black matrix has a limit on the total amount of the oxynitride powder and the oxide powder, so that it is difficult to coexist with a high degree of blackness and high insulation. Further, when the titanium oxynitride powder and the oxide powder are not uniformly dispersed in the resin component, the titanium oxynitride powders are connected to each other to form a conductive path, and the insulating property cannot be maintained. Therefore, it is necessary to make the two components Disperse evenly. Further, in the above method of adding an organic pigment, the insulating property can be maintained, but it is difficult to improve the light-shielding property, and as a result, the thickness of the black matrix cannot be made thin. Further, there is also a problem that organic pigments are discolored due to ultraviolet rays contained in external sunlight or fluorescent lamps. On the other hand, the above-mentioned technique for a black film having sufficient transparency to light having a wavelength from near-infrared to infrared has the following characteristics: a metal material such as carbon black, titanium black, iron oxide, chromium, and silver fine particles. In the inorganic material, the light absorption energy does not have wavelength dependence, or even if the amount of change is small. Therefore, in the black film formed by dispersing these black materials in a material such as an organic resin or an inorganic resin, if the blocking property of visible light is increased, it is present in all wavelengths including infrared rays such as near-infrared rays. In the region, the transmittance is lowered, and it becomes impossible to function as an infrared-transmitting black film. Further, when an organic pigment or a dye is used as the black material, it is feared that the organic pigment or dye is decomposed or deteriorated by ultraviolet rays such as sunlight or fluorescent lamps, and for example, the use of such a filter causes fading. The present invention has been made in view of such a situation, and an object thereof is to provide a volume resistivity which is excellent in light-shielding property and which is given a certain value or more, and is preferably given a value below a certain value of 157917.doc •10-201219465.

According to a second aspect of the present invention, there is provided a black material and a resin component, wherein the black material has an average dispersed particle diameter of 1 nm or more and 1 〇〇 nm or less in a film, and a transmittance per 1 μm thickness at a wavelength of 560 nm ( T560) is less than 40%' and the ratio of the optical density (〇D560) based on the transmittance at 560 nm to the optical density (〇D950) based on the transmittance at 950 nm (OD950/OD560) is 0.35 or less. A black film, a black resin composition for forming the black film, a black material dispersion, a black film-containing substrate including the black film, and an image display device. Hereinafter, the present invention will be described by way of embodiments. <First Invention> (Black Film) The first black film of the present embodiment is characterized in that at least the resin component and the black material 'the black material have a volume fraction of 2% by volume or more and 30% by volume or less' in the film. The average dispersed particle diameter is 1 nm or more, I57917.doc 1j4 201219465 200 nm or less', and the optical density per 1 μπι thickness is i or more, and the volume resistivity is 1011 Ω·cm or more. In the first black film of the present embodiment, the following black material is used, and the black material has a high blackness and is excellent in dispersibility in the resin. Therefore, the optical density of the thickness of the black film of the present embodiment, that is, the optical density per 1 μm thickness, can be easily obtained by setting the volume fraction of the black crucible to 2% by volume or more and 3% by volume or less. A black film having a volume resistivity of 1 〇 11 or more. Further, since the dispersibility is good, the specific dielectric constant at 1 kHz can be 15 or less', and the particle size distribution index D9〇% can be made 600 nm or less. In the first black film of the present embodiment, the volume fraction of the black material must be 2% by volume or more and 30% by volume or less. If the black material is less than the range, the sufficient light-shielding property cannot be ensured when the black film is formed, and if the black material is excessively in the range, the shape, size, or dispersion state of the black material is irrelevant, and the black film becomes low resistance. Therefore, it becomes impossible to obtain the required volume resistivity. The volume fraction of the above black material is preferably 2% by volume or more and 28% by volume or less, more preferably 2% by volume. Above 25% by volume. Further, since the specific gravity of each of the black material and the resin component is known, the volume fraction of the black material in the first black film of the present embodiment can be based on the quality of the black material used as the raw material and the resin forming component. Find out. Further, the resin component is volatilized by decomposition or oxidation at a relatively low temperature. In contrast, since the black material is a metal, it is stable up to a high temperature, because 157917.doc •15-201219465 can be used according to the use of thermogravimetric analysis (TG). , Therm〇gravimetdc (4) (4) The amount of change in the mass of the black film in the black film is determined by the weight ratio of the resin component in the black film. In addition, if the component of the (b) fat component and the black material is determined by component analysis, Since the specific gravity of the two substances can be obtained, the volume fraction of the black material in the black film of the present embodiment can be obtained from the weight ratio obtained and the specific gravity of each component. Further, in the blackening film of the present embodiment The average particle size of the black material in the film must be 纳米 or more and fine nm or less. In the present embodiment, the average primary particle (four) of the black material used is preferably ι or upper, so the right average dispersed particle When the diameter is less than 丨nm, it is difficult to exist as particles. On the other hand, if the average dispersed particle size exceeds (10) coffee, the black film becomes easy to be condensed by the black material particles. The resulting conductive channel 'is therefore difficult to ensure the required volume resistivity, and the light-shielding property also decreases when the aggregation of the black material fine particles is remarkable. The average dispersed particle diameter in the above film is preferably 2 nm or more, 2 〇 〇 (10) or less is more preferably 5 nm or more and 200 ηηη or less. Further, the average dispersed particle diameter in the black film of the present embodiment is a particle diameter corresponding to a cumulative value of 5 % by weight in the case of expressing the particle size by the cumulative distribution. (accumulated 50% particle diameter··median particle diameter). The particle size distribution index in the film of the black material in the first black film is preferably _ nm or less, more preferably 5 〇〇 (10). In the following, if the particle size distribution index /0 in the film is _ nm or less, the unevenness of the particle diameter can be suppressed from being increased, the required radii resistivity can be maintained, and sufficient pre-preservability can be maintained. The above-mentioned particle size distribution index % in the film refers to 157917.doc 201219465 in terms of cumulative distribution, which means that the granules (accumulated 90% of the particle size) corresponding to the cumulative value 粒V. ^ ^ , £t ^ . ... the table does not exist in the black The index of the uniformity of the particle size of the material particles. Further, the lower limit of D90% is ^^ „ ..., especially, but the average particle size of the black material is preferably used. It is 1 nm, so it is difficult to make D90% less than 5 nm in the actual manufacturing step. The above-mentioned black material is flat in the film, and the particle size can be, for example, by using FIB (f〇).

Further, the particle size distribution index D90% was determined by setting the cumulative particle size of the particle diameter of the selected particles to 9% by volume. Furthermore, the cumulative values are all benchmarks. The first black film of the present embodiment must have an optical density of 1 or more per 1 μm thickness. If the optical density per 1 μm is less than 丨', sufficient shading properties cannot be obtained if the thickness of the black film is several μη. Further, in order to obtain sufficient light-shielding property, it is necessary to increase the film thickness, in particular, when it is used as a black matrix or the like, the wire breakage or display unevenness is likely to occur due to an increase in film thickness. Therefore, it is possible to obtain a sufficient light-shielding property without increasing the film thickness to a required level or more, and to set the optical density per 1 μm to 1 or more. 157917.doc • 17- 201219465 Further, the optical density per 1 μm is preferably 1.2 or more and more preferably 1.5 or more. Here, the black material in the present embodiment has a high blackness and is excellent in dispersibility in the resin. Therefore, if the first black film of the embodiment is used, the amount of the black material can be increased. It is easier to maintain the required volume resistivity and to have an optical density of 2 or more per 1 μm. Further, the higher the optical density per 1 μm, the more preferable, but the upper limit is about 10 in terms of measurement limitation. Here, the optical density per 1 μm thickness described above can be obtained as follows. The sample was formed into a film shape on a transparent substrate as a transmission measurement. The optical density of the film sample is measured by a transmission densitometer, and the film thickness is measured using a stylus type surface shape measuring device or the like, and the optical density value of the obtained sample is divided by the film thickness. The optical density of the thickness of the claw. Further, it is preferable that the optical density of the film sample is about 4.0 or less to prevent a decrease in measurement accuracy. In addition, the volume resistivity of the black film must be 1 〇1 1 or more. The reason is that the wiring for driving the element is in contact with a black moment or the like in a liquid crystal display device or a light-emitting display device of a COA method or a BOA system. The wall or the structure in which the component drive wiring is directly provided on the black (four) or the light-shielding wall becomes the mainstream. Therefore, if the black film is used to form a black matrix or the like, the volume resistivity of the light-shielding wall does not reach ι〇11 ω. In the 1PS-driven liquid crystal, if the color matrix formed by using the black film has conductivity, the wiring is likely to be short-circuited, and the liquid crystal of the liquid crystal is used to drive the liquid crystal. 157917.doc -18· 201219465 @There is an unwanted electric field in the direction, causing image confusion. The volume resistivity of the black film is preferably 1 G12 n.emm, more preferably 10 Ω cm or more. The higher the volume resistivity of the black film, the higher the upper limit is not particularly limited, and is usually 1 〇 18 Q.cm or less. Further, the volume resistivity can be measured by using a commercially available volume resistivity meter, for example, by a four-probe method or the like. Further, the specific dielectric constant of the first black film of the present embodiment is preferably 15 or less, more preferably 丨2 or less, still more preferably 6 or less, and particularly preferably 5 or less. When the specific dielectric constant of the black film is 15 or less, when a black matrix or the like or a light-shielding wall is formed using the black film, the influence of the parasitic capacitance or the like on the switching signal for driving the liquid crystal element or the light-emitting element is lowered. This can reduce the confusion of images and the like to the extent that there is almost no influence on the visual. In addition, when the specific dielectric constant of the black film is 6 or less, when a black matrix or the like or a light-shielding wall is formed using the black film, a switching signal for driving the liquid crystal element or the light-emitting element, an image, etc. can be accurately transmitted. There will be no confusion in it. The smaller the specific dielectric constant of the black film, the lower the limit is not particularly limited, but it is usually 2.0 or more at 1 kHz. However, since the influence of the specific dielectric coefficient is proportional to the signal frequency, when the driving frequency of the switching signal in the liquid crystal element or the light emitting element is low, the specific dielectric constant does not need to be low, and if the driving frequency is DC ( For the direct current (DC) level (below 10 Hz), the specific dielectric constant value itself can be ignored.

Further, the specific dielectric constant of the black film can be measured using a commercially available LCR meter (inductance capacitance resistance meter, 157917.doc -19-201219465 resistance meter). The first black film of the present embodiment can obtain a value of a higher volume resistivity and further lower the value of the specific dielectric constant, thereby being preferably used for a liquid crystal display element of a COA mode or a BOA mode, or A black matrix or the like, or a light-shielding wall in a self-luminous display device is generally considered to be as follows. First, it can be cited that the silver tin alloy fine particles as the black material or the mixed fine particles of the silver tin alloy fine particles and the silver fine particles have higher blackness than the carbon black which was previously used as the black material. The amount required is small, that is, when the optical density per thickness of the thickness is set to 1 or more, the volume fraction of the black material in the film is less than that of the prior art. In this way, since the volume fraction of the black material is low, there is no black material in the black film. That is, when the fine particles are densely aggregated with each other, the conductive passages are formed by the fine particles contacting each other without causing such a situation. For other reasons, the dispersibility of the black material can be improved. Dispersion means that the black material has a low degree of cohesion. As described above, even in the case where the volume fraction of the black material is low, if the dispersibility of the black material is low, the black material particles are agglomerated with each other, in particular, agglomerated into a chain shape, so that it is possible to form a conductive path. However, in the black film of the present embodiment, the dispersibility of the black material is high and the average dispersed particle diameter is small, so that the black material is uniformly dispersed in the black film towel, and the invisible $ is caused by the aggregation of the bonds. The case of conductive channels. Thus, in the black film of the present embodiment, the black material is uniformly dispersed without forming a conductive path, so that a high volume resistivity can be obtained. Moreover, the black material itself is a metal and the specific dielectric constant is very high, so that the micro-157917.doc •20-201219465 is particle-shaped and uniformly dispersed in a resin component having a lower dielectric constant to form a high-resistance film. Reduce the specific dielectric constant as the effectiveness of the black film. Further, since the volume fraction of the black material in the black film is low, the effect of lowering the specific dielectric constant can be further improved. Thereby, a lower specific dielectric constant can be obtained. Further, as described in the following black material dispersion or black resin composition, the black material in the present embodiment is subjected to dispersion treatment using a dispersing agent or a dispersing aid, whereby the above-mentioned black film can be easily obtained. The decrease in the dispersed particle size or the decrease in the particle size distribution index. As described above, in the black film of the present embodiment obtained by increasing the dispersibility of the characteristic black material in the film, the volume fraction of the black material is set to 2 volumes. /❶ or more, 3〇 volume% or less, and the average knife-size particle size in the film is 1 nm or more and 200 nm or less, and a volume resistivity of ι π Q.cm or more can be obtained, and each i can be made. The optical density of the μιη thickness is 1 or more. Further, the specific dielectric constant at i kHz can be made 15 or less. - Black material - As the black material used for the first black film of the present embodiment, it is preferable to select metal fine particles H containing silver and tin as main components, and the above-mentioned "silver and tin as main components" means At least 3 silver and tin cores are contained in the metal fine particles, and the total content of silver and tin is 50% by mass or more based on the total amount of the metal fine particles. The composition and content are defined relative to the metal micro-t overall, and are not intended to define the composition and content of each particle itself. 157917.doc -21- 201219465 It has been known that metal microparticles (nano-sized metal microparticles) with a particle size of 1 nm to several hundreds of nanometers exhibit various tones by absorption by surface plasmons of metal. It is also known that the hue varies depending on the composition or particle diameter of the fine particles. In the present embodiment, it is preferable to select metal fine particles which are black by adjusting the composition or the particle diameter, and as the black metal fine particles, metal fine particles containing silver and tin as main components can be selected. As the metal fine particles, silver tin alloy fine particles or mixed fine particles of silver tin alloy fine particles and silver fine particles can be preferably used. Here, in the case where the metal fine particles containing silver and tin as main components are silver tin alloy fine particles, the content ratio of the silver component in the silver tin alloy fine particles, that is, the ratio of the silver component to the total amount of silver and tin ( Silver/(silver+tin):% by mass) is preferably C% by mass or more and 95% by mass or less, more preferably 6% by mass or more, and 95% by mass or less, more preferably 62% by mass or more and 95% by mass or less. , especially good for 65 quality. /. Above '95 mass% or less. When the metal fine particles containing silver and tin as main components are fine particles of silver tin alloy fine particles and silver fine particles, the content of the silver component in the mixed fine particles of the silver tin alloy fine particles and the silver fine particles, that is, the silver component The ratio (silver/(silver + tin): mass%) to the total amount of silver and tin is preferably 45 mass% or more and 95 mass% or less, more preferably (9) mass% or more and 95 mass%. In the following, it is preferably 62% by mass or more and 7% by mass or less, and particularly preferably 65% by mass or more and 95% by mass or less. The reason why the content of the silver component is limited to the above range is that when the ratio of the silver component is 45 mass% or more and 95 mass% or less, the reflectance of light does not become high and the blackness of sufficient blackness is obtained. Membrane, and 157917.doc -22- 201219465 to obtain sufficient light interception. Further, when the preferred content range of the silver component is a predetermined amount of the silver tin alloy fine particles or the mixed fine particles of the silver tin alloy fine particles and the silver fine particles, the preferred content ratio of the silver component in the entire fine particle is @者' is not a range indicating a preferred content rate of the silver component in each particle. Here, the silver tin alloy fine particles are, for example, those including a crystal structure having a silver-tin alloy (hereinafter also referred to as "silver-tin alloy phase") or a crystal structure having silver ( Hereinafter, it is also called "silver phase"). f first 'as a silver-tin alloy phase, in the case of a silver-tin alloy represented by the chemical formula Agl_xSiix, it is known that the range of X is 0.118 0.2285 (space group? 63/111111 (〇 and 0.237$ and $0.25) 8 phase (space group Pmmn) (according to Binary Alloy Phase Diagram, ρ· 94-97). It is generally considered that if the phase composition and space group and X-ray diffraction ICDD (International Centre for Diffraction Data, international powder crystal Compared to the JCPDS (Joint Committee on Powder Diffraction Standards) card, the X-ray diffraction data of the Bellow phase is equivalent to Ag3Sn (IDCC 71-0530). The X-ray diffraction data is equivalent to Ag4Sn (IDCC 29-1151). Therefore, if it is a silver-tin alloy fine particle having an ε phase (Ag3Sn) as an orthorhombic system or a ruthenium phase (Ag4Sn) as a hexagonal system, It can satisfy the chemical stability and blackness. Secondly, as the silver phase, that is, the crystal structure having silver, it means that one of the silver atoms in the silver crystal 157917.doc -23- 201219465 is replaced by a tin atom. Yu Yu When the formula Agi-ySriY indicates the case of the silver-tin alloy in this case, the range of γ is 0 &lt; lt 0.115 ' is represented by the (Ag) phase (space group represented by the following formula: cubic crystal system) in the above literature. [Number 1]

Fm3m If AgzSn (Z is a real number) is used to represent the range, the range of z is 7.70S Z &lt;〇〇 (infinity). Furthermore, in the above chemical formula, Y = 0 (AglSn 〇) or z = 〇〇 (Ag 〇〇 Sn s _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ However, in the present embodiment, the metal fine particles containing silver and tin as main components used as the black material are not only silver tin alloy fine particles but also mixed fine particles of silver tin alloy fine particles and silver fine particles. Further, the black material containing the silver tin alloy fine particles or the fine particles of the silver tin alloy fine particles and the silver fine particles is substantially free of tin fine particles. Here, the term "substantially does not contain tin fine particles" The presence of a substance having a crystal structure of tin was not confirmed in the analysis by the line diffraction method. When the black material contains tin fine particles, the light blocking property of the black light-shielding film formed using the black material is greatly lowered. In the present embodiment, the average primary particle diameter of $# marriage_ + π & , , 1 Wenyang &...e material is preferably nm or more and 200 nm or less, and the helmet is occupied. &lt;h is more preferably 5 nm or more and 2 〇〇 nm or less. Here, the reason why the average primary particle diameter is limited to the above range is that the 157917 can be formed relatively easily by arranging the average-times in the upper state (fourth). Doc -24· 201219465 Black film required. That is, the reason is that if the average-secondary particle diameter is less than 1 (10), it is too small compared with the wavelength of visible light. Therefore, the localized surface plasmon absorption of the metal which is a main factor of light absorption is reduced, and it becomes impossible to obtain On the other hand, if the average primary particle diameter exceeds 2 〇〇 nm, the range of electron motion on the surface of the particle becomes wider, so that the localized surface plasmon absorption of the metal is reduced, and the blackness is reduced. Reduce the situation. As a method of producing the black material used in the present embodiment, as described above, the method of obtaining the fine metal particles by adjusting the composition or the particle diameter is not particularly limited, and a gas phase reaction method or a spray can be applied. A general metal microparticle synthesis method such as a mist thermal decomposition method, a liquid phase reaction method, a freeze drying method, or a hydrothermal synthesis method. In particular, in the case of selecting silver tin alloy fine particles or mixed fine particles of silver tin alloy fine particles and silver fine particles as the metal fine particles, it is preferred to use a liquid phase reaction method which can obtain such fine particles relatively easily. As the liquid phase reaction method, for example, a silver compound solution and a reducing agent may be added dropwise to the tin colloidal dispersion liquid, and tin may be alloyed by reacting with silver ions, and silver fine particles may be formed from silver ions, thereby forming silver tin alloy fine particles. Method with silver particles. In the production method, the formation of the silver-tin alloy fine particles can be arbitrarily controlled by appropriately adjusting the reaction conditions (for example, the ratio of tin to silver ions, the pH of the reaction liquid, the reaction temperature, the reaction time, the amount of reduction, etc.). The amount of silver particles generated (including the case where silver fine particles are not substantially formed, that is, when only silver tin alloy fine particles are formed), and the ratio of the amount of silver tin alloy fine particles to silver fine particles. 157917. Doc • 25- 201219465 In the manufacturing method, the synthesis is completed by the reaction in the liquid phase, so that the obtained black material containing the metal fine particles becomes dispersed in the liquid phase of the water system' can be directly or by simple The procedure was used as a black material dispersion of the following water dispersion system. Further, when a black film is formed using the black material, the dispersibility of the black material and the resin forming component may be considered, and the dispersion medium of the dispersion may be an organic solvent system as described above. In the case of obtaining a liquid phase in a liquid phase, in the case of preparing a dispersion of an organic solvent system, the following method may be employed: temporarily, the bulk aggregate recovered from the liquid phase of the water system is mechanically pulverized to form a powder. Thereafter, the dispersion treatment is carried out in an organic solvent using a wet mixer such as a ball mill or a bead mill. Further, if possible, the dispersion can be changed by directly replacing the solvent with a solvent. - Resin component - The resin component in the present embodiment may be selected so as to be cured in a state in which the black metal particles which are black materials are uniformly dispersed, and which meet the characteristics required for the formed black film. As the resin component, various ionizing radiation curable resins, thermosetting resins, thermoplastic resins and the like can be used. The above-mentioned ionizing radiation curable resin is a resin which is cured by crosslinking or polymerization reaction by irradiation with, for example, an ultraviolet ray or an electron beam as an electromagnetic wave or a charged particle beam, and examples thereof include a radical polymerization type acrylic resin, Unsaturated polyester resin, or cationically polymerized epoxy resin, vinyl ether resin, oxetane, and glycidol. 157917. Doc -26-201219465 The acrylic resin may, for example, be a polyester (mercapto) acrylate resin, an epoxy (meth) acrylate resin, a (meth) acrylate methyl methacrylate resin, or a plurality of An alcohol (meth) acrylate resin, a polyoxo acrylate resin, or the like. Here, the term "(meth)acrylic acid vinegar" means "acrylate or methacrylate". The same is true below. Further, 'the above-mentioned thermosetting resin may, for example, be a resin, a resin, a urea resin, a urea-formaldehyde resin, a melamine resin, a polyester trisamine resin, a melamine-aldehyde resin, an alkyd resin, or a ring. Oxygen resin, epoxy _ melamine resin, unsaturated polyester resin, polyimide resin, acrylic resin, polyoxyalkylene resin, polyamine phthalate resin, general-purpose 2-liquid hardening type Acrylic resin (acrylic polyol cured product) or the like. Further, as the thermoplastic resin, a polyester resin, an alkyd resin, a polyamino phthalate, a polyvinylpyrrolidone, a polyvinyl alcohol or the like is preferably used. In the case where the first black film of the present embodiment is formed into a black matrix or the like, it is preferable to select an alkali-soluble resin as a resin-forming component which is a raw material of the resin component, and to use a resin formed of the resin-forming component as a resin component. . Furthermore, since the specific dielectric constant of the resin (organic material) is generally low, there is almost no selection restriction factor of the resin component for the specific dielectric constant of the black film of 15 or less, but in a part of the resin such as phenol resin. There is a case where the specific dielectric constant exceeds 1 因 due to the composition and the like, and therefore it is sometimes necessary to pay attention. - Method for producing black film - The first black film of the present embodiment is obtained by forming a film body by various known coating methods using the following black resin composition. For example, black 157917. Doc -27-201219465 The film can be easily obtained by the following steps: the above-mentioned black resin composition is applied to the base by various coating methods such as roll coating, spin coating, dip coating, spray coating, and bar coating. One of the main surfaces is formed (coated) into a layered shape to form a coating film. The solvent is removed from the coating film by volatilization or the like, and is subjected to a hardening treatment as needed. In the curing treatment, the resin component in the coating film is usually reacted by polymerization or the like to form a resin component, and when an ionizing radiation-curable resin is used as the resin component, ultraviolet rays, electron beams, and In the case of irradiation with radiation such as X-rays (heat treatment may be performed after irradiation, if necessary), a heat-reactive resin such as a thermoplastic resin material to which a thermal polymerization catalyst is added may be used as a resin-forming component, and heat treatment may be mentioned. The irradiation amount of the radiation is a sufficient amount required for the ionizing radiation-curable resin to be sufficiently hardened, and is usually 2 〇 mJ/cm 2 or more and 1 〇〇〇 mJ/cm 2 or less. Further, the temperature of the heat treatment is not particularly limited as long as the heat-reactive resin is sufficiently cured, and the resin itself is not modified or deformed, and the temperature at which the substrate can be used is not particularly limited, and for example, it can be exemplified in an atmospheric environment, 80 Heat treatment at a temperature in the range of C to 300 C for about 3 minutes to about 12 minutes. Further, when the component in the black resin composition is a resin component dissolved in a solvent, the hardening treatment becomes a self-coating film. The step of removing the solvent from the resin component may be a heat treatment under atmospheric pressure or under reduced pressure. In this case, the resin component which is hardened by removing the solvent may be swollen and dissolved again by exposure to the same solvent, and therefore it is preferably set by rigorously setting 157,917.

When the ionizing radiation-curable resin is used as the resin component, it is possible to irradiate radiation such as ultraviolet rays, electron beams, and x-rays after the solvent is removed, or to perform heat treatment to completely cure the heat-reactive property. When the resin is used as the resin component, the curing reaction can be completed by the heat treatment after the removal of the solvent. β (black material dispersion) The black material dispersion of the present embodiment (hereinafter sometimes simply referred to as "dispersion") A dispersion obtained by dispersing the black material of the above embodiment in a dispersion medium. In the dispersion, the average dispersion particle diameter of the black material is 1 nm or more, and the particle size distribution index in the x-knife dispersion medium is 1) 90 〇 / 〇 is 600 nm or less. - Dispersing medium - [Knife-scattering" is basically one of the components containing water, an organic solvent, and a resin. As the above-mentioned organic solvent, for example, methanol, ethanol, 2: alcohol: alcohol, alcohol such as octanol; acetic acid, butyl acetate, lactic acid-hydrazine, propylene-alcohol, mono-W acetic acid monolactone, etc. are preferably used. Ester; diethyl ether, ethyl γτ alcohol, single ethyl group, cellosolve, scream (methyl cellosolve), ethylene glycol monomethyl hydrazine, · (butyl cellosolve, diterpene, decyl isobutylidene , methyl ethyl benzene, monoterpene benzene ^ ethyl propylene _, cyclohexyl and other steels; stupid '曱-曱, B, and other aromatic hydrocarbons; dimethyl ketone, dimethyl 157917.

When the moisture content of the right second dispersion is more than 5% by mass, when the dispersion of the black material r·· is mixed with the non-aqueous resin component or the resin-forming component, the dispersion liquid and the resin component or the resin component are changed. In the case where it is easy to obtain a stable mixture (black resin composition), it is possible to appropriately select a suitable one from a plurality of non-aqueous photosensitive resins by setting the water content of the dispersion to 5% by mass or less. The exposure, development conditions, physical properties, and the like are not restricted to the dispersion or the coating film, and the degree of freedom of the design can be broadened. - Other components - In the dispersion of the present embodiment, In order to improve the dispersibility of the black material and to improve the dispersion stability, it is preferred to use a dispersing agent and/or a dispersing aid in combination. Among them, especially when a polymer dispersing agent is used as a dispersing agent, the dispersion over time is qualitatively superior 4 Preferably. Here, the term "dispersant" refers to a polymer which ensures the dispersibility of a black material and a polymer which is completely free from a black material. The term "dispersion aid" refers to a pigment derivative for improving the dispersibility of a black material. For example, a carboxylic acid 'polyoxyethylene alkyl ether component, a sorbitan fatty acid ester is generally classified as a polymer dispersant, an ester dispersant, a polyethyleneimine dispersant powder, and a polyoxygen. Ethylene glycol diester dispersant 157917. Doc 201219465 is a dispersant, an aliphatic modified polyester dispersant, a polycarboxylate, a polyalkyl sulfate, and a polyethylene 0 to p. The same as g (PVP, polyvinyl pyrr〇lid〇ne), polyvinyl alcohol (PVA, polyvinyl alcohol), polyacrylamide and the like. In the above, the urethane-based dispersant is preferred in consideration of the compatibility with the ionizing radiation curable resin, the thermosetting resin, the thermoplastic resin used as the resin, and the compatibility with the organic solvent. Further, when the polymer dispersant is classified according to the structure depending on the production method, a random copolymer, a comb-shaped copolymer, a fluorene-type block copolymer, a bab-type block copolymer, and two A polymer having a hydrophilic group at the terminal, a polymer having a hydrophilic group at one end, and the like. Among these, a random copolymer or a comb-shaped polymer is preferable in consideration of compatibility with an ionizing radiation curable resin, a thermosetting resin, a thermoplastic resin, and an organic solvent used as a resin. . Specific examples of the dispersing agent under these conditions are listed by product name. EFKA (manufactured by EFKA Chemicals BV (EFKA) Co., Ltd.), (4) Kiss k (manufactured by BYK-Chemie Co., Ltd.), and café-made company. These dispersants are available! Use 2 types or more. Further, the dispersions are also polymers (resins) having a lower specific dielectric constant. Therefore, there is almost no limiting factor for making the specific dielectric constant of the black film (IV). Further, the amount of the dispersing agent added to the coloring material 枓 is preferably 5 parts by mass or more and not more than 1 part by mass relative to the mass fraction of the powder. If the amount is less than 5 parts by mass, then there is a case where the black microparticles are insufficiently dispersed to maintain the dispersion of the dispersion 157917. Doc -31· 201219465 i·Life cannot satisfy the average dispersed particle diameter in the above dispersion, the average particle diameter in the film, and the volume resistivity of the film. Further, if the dispersion amount is more than 50, there is a case where the dispersion amount becomes excessive with respect to the black fine particles, and the dispersion of the dispersion liquid cannot be maintained due to the interaction of the dispersants and the like, and the average of the above dispersions cannot be satisfied. The dispersed particle size, the average dispersed particle size in the film, and the volume resistivity of the film. In the black material dispersion liquid of the present embodiment, the black material of the present embodiment is dispersed in a dispersion medium, and the above-mentioned "other components" are added as needed. Here, the average dispersed particle diameter of the above black material in the dispersion must be 1 nm or more and less. In other words, since the average-secondary particle diameter of the preferred black material used in the present embodiment is i (10) or more, it is difficult to exist as a black material fine particle having an average dispersed particle diameter of less than i nm. On the other hand, if the average dispersed particle diameter exceeds 2 〇〇 (10), the conductive film formed by the aggregation of the black material particles is likely to be generated in the black film formed using the dispersion liquid, so that it is difficult to secure the required volume resistance. The light-shielding property also decreases when the aggregation of the black material particles is remarkable. Further, when the average dispersed particle diameter is increased, it is difficult to maintain a stable dispersion state in the dispersion liquid itself. The average dispersed particle diameter is preferably 2 nm or more and 2 〇〇 nm or less, more preferably 10 nm or more and 150 nm or less. In addition, the particle size distribution index of the above black material in the knife solution is D90% (accumulated 90% diameter) must be 600 nm or less. If it exceeds 6 〇〇 nm, the particle size non-uniformity becomes too large, and the coarse particles contained therein maintain a stable dispersion state in the dispersion itself, and it is difficult to form a black film 157917 using the dispersion. Doc -32- 201219465 "It is difficult to maintain the required volume resistivity and ensure adequate shading. The particle size distribution index D9 〇 % in the above dispersion liquid is more preferably 5 Å or less. Further, the lower limit of D90% is not particularly specified, but since the lower limit of the average particle diameter of the black material is i nm ', it is difficult to make D90% less than 5 nm in the actual dispersion step. For the average dispersed particle size of the above-mentioned dispersion liquid towel, (4) the particle size distribution of the dispersion liquid by the dynamic light scattering method (4), the volume average particle diameter obtained by arithmetic mean averaging according to the distribution result obtained ( The MV value, mean volume di_ter) is set as the average dispersed particle diameter. On the other hand, when the particle size is expressed in terms of cumulative distribution (volume basis), the particle size distribution index D90% can be obtained by setting the particle diameter (accumulated 90% particle diameter) corresponding to the cumulative value of 9% by weight. The average dispersed particle diameter and particle size distribution index in the following black resin composition can also be determined by the same measurement method.

When the amount is 80% by mass or less, the black material may exhibit a good dispersion state in the dispersion.

It is difficult to obtain the desired black film, or the cost of removing the dispersion medium is increased.

The black material dispersion liquid of the present embodiment can be prepared by mixing and dispersing the black material, a component such as a dispersing agent, or a dispersing aid, in the dispersion medium. As the mixing and dispersing method, a known dispersing machine such as an ultrasonic disperser paint shaker, a ball mill, a bead mill, or an Eiger mill can be used to disperse a mixture of a black material or a resin forming component. However, in terms of improving the dispersibility, it is preferred to use a bead mill. Further, a plurality of dispersion methods may be used in combination. (Black resin composition) The black resin composition used for the formation of the first black film of the present embodiment contains at least the resin composition of the black material, the resin component or the resin component of the present embodiment, and includes a black paint or the like. Further, the term "resin forming component" means a component for forming the above resin component. In the black resin composition, the black material has an average dispersed particle diameter of 1 nm or more and 200 nm or less. That is, since the average primary particle diameter of the preferred black material used in the present embodiment is 丨nm or more, it is difficult to have another right average dispersion as a black material fine particle having an average dispersed particle diameter of less than 1 nm. When the particle diameter exceeds 200 nm, in the black film formed using the black resin composition, the conductive path caused by the aggregation of the black material particles is easily generated, so that it is difficult to secure the required volume resistivity, and the black material is required. When the aggregation of the fine particles is remarkable, the light blocking property also decreases. Further, when the average dispersed particle diameter is increased, it is difficult to maintain the stable state of the black material in the black resin composition itself. 157917.

Further, the above black material in the black resin composition has a particle size distribution index of D90 ° / 〇 of 600 nm or less. If it exceeds 600 nm, the unevenness of the particle size becomes too large, and it is difficult to maintain the stable dispersion state of the coarse particles contained in the dispersion in the dispersion liquid, and it is maintained in the black film formed using the dispersion liquid. The volume resistivity and ensuring sufficient light blocking properties become difficult. Further, the particle size distribution index D90% in the above black resin composition is preferably 500 nm or less. Further, the lower limit of D9〇% is not particularly specified, but since the lower limit of the average particle diameter of the black material is i nm, it is difficult to make D90% less than 5 nm in the actual dispersion step. Further, the method of measuring the average dispersed particle diameter and the particle size distribution index D90% in the black resin composition can be determined by the same measurement method as that described above for the black material dispersion. Here, the total content of the resin component and the resin-forming component in all the solid content components contained in the black resin composition is preferably 5% by mass or more and 7 Å by mass. /.

Doc -39·201219465 Reagent, reaction initiator, or polymerization initiator, polymerization initiator, etc. β is produced by patterning a black film using the above black resin composition into a specific shape, for example, a black matrix In the case of using a black resin composition containing a testable resin, a photopolymerization initiator, and an ethylapatotic unsaturated compound, the black resin composition is formed into a layered coating film having light ( Ultraviolet light). When the coating film is photosensitive, the coating film is exposed to a specific pattern using a mask or the like, developed, and hardened, whereby a black film having a specific shape such as a black matrix can be easily obtained. The alkali-soluble resin is not particularly limited as long as it is a resin containing a carboxyl group or a hydroxyl group, and examples thereof include an epoxy acryl vine resin, (iv) a varnish resin, a polyvinyl phenol resin, an acrylic resin, and a carboxyl group-containing resin. Epoxy resin, urethane resin containing a slow base, and the like. Among these, preferred are epoxy succinic acid s, resin, secret resin, acrylic resin, which provide a higher volume resistivity and a lower specific dielectric coefficient δ, Particularly preferred is a resin having an aromatic ring structure. In this case, the ratio of the solvent-soluble resin to the total solid content of the black resin composition is preferably 5% by mass or more and π% by mass or less, more preferably 1% by mass or more and 50% by mass or less. When the proportion of the test-soluble resin is more than 5% by mass or more and 7% by mass or less, there is a case where the black matrix (4) is not sufficient to ensure sufficient sensitivity, and it is also advantageous to ensure the necessary light-shielding property. On the other hand, if there are too few, there is a case where the method forms a preferable shape of the resin black matrix. The above-mentioned photopolymerization initiator means that 1579l can be produced by ultraviolet light or heat. Doc 201219465 A compound that polymerizes a free radical of an ethylenically unsaturated group. As a photopolymerization initiator, in particular, in terms of sensitivity, an anthracene derivative (a Chiang-based compound) is effective, for example, a light-shielding property is improved, and a sensitivity is obtained by using an alkali-soluble resin containing a phenolic hydroxyl group. On the other hand, it becomes disadvantageous, and in particular, such an anthracene derivative (anthracene compound) excellent in sensitivity is useful. In the present embodiment, the photopolymerization initiator may be used singly or in combination of two or more. In the case where the dendrimer black matrix is formed, the proportion of the photopolymerization initiator in the dispersion is preferably 〇 4% by mass or more and 15% by mass based on the total solid content. Hereinafter, it is more preferably 〇 5 mass y ❶ or more and 丨〇 mass % or less. If the proportion of photopolymerization initiator is too much. In the range of 4% by mass or more and 15% by mass or less, the development speed may be too slow. On the other hand, if it is over, sufficient sensitivity cannot be obtained, and a preferable resin black matrix shape cannot be formed. The situation. The above-mentioned ethylenically unsaturated compound is a compound having one or more ethylenically unsaturated bonds in the molecule, and as the compound, the polymerization is steep, the crosslinkability, and the development of the exposed portion and the non-exposed portion can be enlarged. In terms of the difference in the solubility of the liquid, it is preferably a compound having two or more ethylenically unsaturated bonds in the molecule, and more preferably, the unsaturated bond is derived from a (fluorenyl) propylene oxy group.

Ethylene (meth) acrylate compound and polyisocyanate compound (meth) acrylate phthalate, and (meth) acrylate or hydroxy (meth) acrylate compound and polyepoxide epoxy ( Mercapto) acrylates and the like. - Solvent-forming component or solvent of resin component - Solvent as a resin-forming component or a resin component (hereinafter referred to as "resin solvent"), the solubility of the resin-forming component or the resin component is lower than that of the south liquid One or more selected from the group consisting of water and an organic solvent. As the resin solvent, in addition to the solubility of the resin-forming component or the resin component, it is necessary to satisfy the following conditions: the dispersibility of the black material is higher than that of the black material dispersion; and the black material dispersion When mixed, the dispersibility of the black material or the solubility of the resin component or the resin-forming component does not decrease. When the conditions are not satisfied, even if the "black material dispersion" and the "solution of the resin-forming component or the resin component" are stably present, when the two are mixed to form a black resin composition, phase separation occurs. The aggregation or precipitation of a black material, the precipitation of a resin component or a resin component, etc., make it impossible to obtain a favorable black resin composition. In this regard, if the same or similar solvent can be selected as 157917. Doc •42· 201219465 Resin solvent and black material dispersion can avoid this problem, so it is better. In addition, as the above organic solvent, the organic solvent used in the above black material dispersion can be used in the same manner. Further, in the above-mentioned black resin composition, in order to improve the dispersibility of the black material and to improve the dispersion stability in the same manner as the black material dispersion, it is preferred to use a dispersant and/or a dispersing aid in combination. In particular, when a polymer dispersant is used as a dispersing agent, since it is excellent in temporal dispersion stability, it is preferable that the dispersing agent or the dispersing aid is the same as those described in the black material, and therefore the description thereof is omitted. Detailed description. Further, when a dispersion liquid containing a dispersant and/or a dispersing aid is selected as the black material dispersion liquid of the present embodiment, and the black material dispersion liquid is used as a raw material of the black resin composition, the dispersion liquid may be used as it is. A dispersant or dispersing aid of both. The reason for this is that the dispersant or the dispersing aid is such that the surface of the black material is a substance having an affinity for a dispersion medium or a solvent by modifying the surface of the black material. Therefore, if the characteristics of the dispersion medium or the solvent are not changed, it is not necessary. Treatment with other types of dispersants or dispersing aids. - Method for Producing Black Resin Composition - The black resin composition described above can be prepared by at least selecting the above black material and resin forming component and/or resin component, and optionally adding a black material dispersion medium or resin. The solvent of the component or the resin component is further mixed and dispersed by adding other components such as a photopolymerization initiator or a dispersant. Also, regarding these black materials, black material dispersion medium, 1579l7. Doc •43· 201219465 The combination of the resin forming component, the resin component, the resin forming component or the resin component is as described above. In this case, a black resin composition can be prepared by previously preparing a black material dispersion, adding a resin forming component or the like, or a photopolymerization initiator to dissolve it. Further, it can be prepared by mixing a previously prepared black material dispersion liquid, a solution obtained by dissolving a resin forming component or the like, or a photopolymerization initiator. The mixing and dispersing method is a treatment of a mixed liquid in which a black material or a resin forming component is mixed, by a known dispersion treatment method such as an ultrasonic disperser, a paint shaker, a ball mill, a bead mill, or an Eiger mill. Yes, but in terms of improving dispersibility, it is preferred to use a bead mill. Further, a plurality of dispersion methods may be used in combination. Further, in the case of using a black material dispersion prepared in advance, the above-described dispersion treatment method is not carried out in the production of the black resin composition, and the black material dispersion liquid and the solution for dissolving the resin component or the like are sufficiently provided. (When mixing and stirring are possible) (Substrate with black film) The substrate with the black film of the present embodiment is formed by providing the first black film of the present embodiment described above on the substrate. Specifically, for example, it is produced by patterning a layer formed on the light-transmitting substrate by the above-described black resin composition as described above. The substrate is not particularly limited, and examples thereof include a glass substrate and a plastic substrate (organic polymer substrate). Further, examples of the shape thereof include a flat plate, a film shape, and a sheet shape. Moreover, as the plastic substrate, plastic 157917 is preferred. Doc -44- 201219465 Film, plastic film, etc. The material of the glass substrate is not particularly limited, and may be, for example, suitably selected from the group consisting of soda glass, alkali glass, and alkali-free glass. The material of the plastic substrate is not particularly limited, and may be, for example, cellulose acetate, polystyrene, or polyethylene terephthalate (pET, p〇iyethyiene) depending on the use or use conditions. Terephthalate), polyether, polyimine, epoxy resin, stupid oxy resin, polycarbonate (PC, p〇lycarb〇nate), polyvinylidene fluoride, triacetyl cellulose, polyether sulfone (PES, Polyether sulfone), polyacrylate, etc. Moreover, the method of patterning the layer formed using the above-mentioned black resin composition is not particularly limited, and as described above, the alkali-soluble resin, the photopolymerization initiator, and the ethylenically unsaturated compound may be contained in the black resin composition. The black resin composition is formed into a layered shape to form a coating film having light (ultraviolet) photosensitivity, and the coating film is exposed to a pattern and then developed to form a black film. It is composed of post-exposure or post-bake special steps. Regarding the above-described patterning step of exposure, development, and the like, a well-known method can be used. However, for example, when it is used as a black matrix for an image display device, the paragraph number of the Japanese Patent Laid-Open Publication No. 2〇〇6_251〇95 〇 The method of forming the light-shielding image described in the method of the present invention, or the method of forming the light-shielding image described in paragraphs 0116 to 0126 of JP-A No. 6-251237, is also preferably used in the present embodiment. Further, the above black resin composition was also used, and an ink jet method was used, based on 157917. Doc •45- 201219465 The method of directly forming a patterned layer on a material. In this case, it is not necessary to provide photosensitivity to the coating film of the black resin composition, but the black resin composition to be used must be excellent in ejectability (stability in ejection amount or ejection direction) from a minute inkjet nozzle. After being ejected and attached to the substrate, the film is in a high viscosity state without flowing out or deforming. Therefore, a method of adjusting the viscosity of the black resin composition or adding an auxiliary agent for providing the shake resistance is used. A well-known method can be used for this step, but for example, when it is used as a black matrix for an image display device, the paragraph number 〇〇29 to 〇〇3 of Japanese Patent Laid-Open Publication No. 2008-i16895 can be used. The method described in 丨. The substrate to which the black film is attached in this embodiment can be used as a black matrix substrate in which a black matrix (light-shielding film) is omitted, and is preferably used for producing a color filter. &quot; The film thickness of the black film as the black matrix substrate is preferably 〇 2 ^ above, 5. 0 μΓΠ or less, especially good. 2 μβ1 or more and 4 〇 μιη or less. Further, since the first black film of the present embodiment is used as the black film in the black matrix substrate, even the film has a high optical density. (Image Display Device) The first black film of the present embodiment can be preferably used in various image display devices. Examples of the image display device include a plasma display device, a self-luminous display device such as an EL display device, a CRT (four) ray tube, a cathode ray tube display device, a liquid crystal display device, and the like, which are used for liquid crystal display. This device can be used significantly in the case of a device or an EL display device. Doc • 46 · 201219465 The effect of the black film of the embodiment. Here, examples of the type of the liquid crystal display device include STN (Super-twisted nematic), TN (twisted nematic), VA (Vertical Alignment), and lPS. (in-plane switching, transverse electric field switching type), OCS (optical communication system), and R-OCB (Reflective Optically Compensated Bend). Since the first black film of the present embodiment has a high degree of blackness and a relatively high resistivity, it can be preferably used as a member for an image display device using the light blocking property (light antireflection property) and the south resistivity. . Examples of the members include a black matrix in a liquid crystal display device or a self-luminous display device, and a color filter or black stripes using the same, and are separated between pixels of respective colors in a liquid crystal display device or a self-luminous display device. The light shielding wall, the separator between the substrates filled with the liquid crystal in the liquid crystal display device, and the like. YU Ying: When the black matrix and the color filter using the above are used, the thickness of the black matrix can be reduced because the black color is smaller than η. As a result, since the surface of the obtained color filter has high flatness, the liquid 曰曰T device including the color filter does not cause cell gap unevenness between the color grading sheet and the substrate, and the color The occurrence of unequal display defects is improved. Furthermore, because of the volume resistivity, ^ _ _ hand season, such as COA mode or BOA mode of liquid crystal display elements or spontaneous shackles.  &amp; display device, even in the black matrix and pixel drive wiring contact room privacy.  In the case of a dome shape, the driving failure of the 7L member caused by the short circuit of the wiring or the like is not caused. In addition, when applied to the shading wall 戍 4 kn. k, the volume resistivity is also higher than 157917. Doc 201219465 is high, so there is no short circuit between the pixels, so there is no driving failure of the components. Further, since the degree of blackness is high, the thickness of the light-shielding wall can be made small, and the contrast of the enlarged light-emitting region under each pixel can be improved, or the density of the light-emitting element can be increased with the decrease of the pixel interval. Further, it can be applied to a contrast-enhanced film or the like by using a high light absorptivity. <Second Invention> Next, the second invention will be described. (Black film) The second black film having infrared transmittance in the present embodiment is characterized in that it contains a black material and a resin component, and the average particle diameter of the black material in the film is 1 nm or more and 100 nm. Hereinafter, the transmittance (T560) per 1 μm thickness at a wavelength of 560 nm is less than 40%, and the optical density (OD560) based on the transmittance at a wavelength of 560 nm and the optical density based on the transmittance at a wavelength of 950 nm (OD950) The ratio (OD950/OD560) is 0. 35 or less (There is a case where "optical density based on transmittance" is simply referred to as "optical density"). Further, the second black film of the present embodiment also has sufficient light blocking properties and a high volume resistivity as those of the first black film. Further, in the present embodiment, the wavelength band of visible light is "the short wavelength limit is 360 to 400 nm, and the long wavelength limit is 760 to 830 nm" according to JIS-Z8 120, and is set to 380 nm or more and less than 800 nm. . Further, light having a wavelength of 800 nm or more and 1 mm or less is made into infrared rays, and light having a wavelength of 800 nm or more and 2500 nm or less is made into near-infrared rays. Furthermore, the above mentioned 157917. Doc-48-201219465, "Optical Density" refers to the above-mentioned formula when the transmittance is τ (%), and the "infrared transmission black film" in the present embodiment means 3. 0% or more of the infrared transmission film. Further, in the present embodiment, the transmittance (Two) at a wavelength of 56 〇 nm is selected as an index indicating the transmittance because the wavelength is located substantially at the center of the visible light band, and is widely used as a wavelength representing visible light. Here, T56〇 is set to less than 40°/. The reason is that if the visible light transmittance is less than 40%, the film can be regarded as black in appearance (visually observed). That is, the reason is that the visible light transmittance of the member covering the light-emitting portion or the light-receiving portion of the remote controller is not 40°/. It is difficult to observe the internal light-emitting element or the light-receiving element via the member, and the inside can be regarded as a state concealed by the black film. D. 56 is preferably 37. /. The following 'better is 35% or less. Further, the lower limit of τ560 is not particularly limited, but the detection limit of the measuring device is 〇 〇〇〇〇〇 1% or so. Further, the ratio of the optical density (OD56q) at a wavelength of 560 nm to the optical density (〇D95〇) at a wavelength of 95 〇 nm (ODmq/OD56) is 0. Below 35, the necessary amount of transmitted light can be obtained especially for light of 950 nm which is mostly used for wireless remote controllers. OD95〇/〇D56〇 is preferably 0. 32 or less 'better is 0. 30 or less. Furthermore, the lower limit of od95Q/od56() is 〇. 1 or so. Further, in the second black film of the present embodiment, the ratio of 〇d56() to the optical density (ODNIR) at each wavelength in the near-infrared (NIR) wavelength region of 800 nm or more and 2500 nm or less (ODNIR/〇) D56()) is preferably 0. 40 or less. If ODNIR/OD56() is 0. Below 40's have a shading of visible light 157917. Doc-49-201219465, and can obtain a sufficient amount of transmitted light for various near-infrared lasers for industrial use or infrared rays for positioning black matrix patterns, and therefore can be preferably used as an infrared-transmitting black film. ODN丨R/〇D560 is preferably 0. 37 or less, further preferably 0 35 or less β, and the lower limit of ODNIR/〇D56〇 is 0. In the second black film of the present embodiment, the integral ratio of the black material is preferably set to 1 〇 volume. /. Above 25% by volume. By setting the volume fraction to this range, sufficient light-shielding property can be ensured in the visible light region when a black film is formed, and a high transmittance can be obtained for light above the near-infrared region. That is, the volume fraction of the 3⁄4 black material is less than one.  If the volume is 5%, the black material is too small, so there is a case where the light-shielding property in the visible light region is insufficient. On the other hand, the reason is that if the volume fraction of the black material exceeds 25 volume Μ, the infrared transmission black film has metallic luster, so that the transmittance of light above the near-infrared region is also lowered, and even if it does not occur In the case of metallic luster, since the amount of the black material is too large, there is a case where the transmittance of light in the near-infrared region is also lowered. The volume fraction of the above black material is more preferably set to 2. It is more preferably 0% by volume or more and 2% by volume or less, and more preferably 2% by volume or more and 15% by volume or less. Further, in the second black film of the embodiment, the volume fraction of the black material can be calculated from the density of each component constituting the infrared ray transmitting black film and the weight of each component added at the time of coating. The volume of each component was determined. Further, the resin component is volatilized by decomposition or oxidation at a relatively low temperature. In contrast, since the black material is a metal, &amp; is stable up to a high temperature, 157,917. Doc •50- 201219465 Therefore, the weight ratio of the resin component to the black material in the black film can be determined according to the weight change of the black film by thermogravimetric analysis (TG), and on the other hand, the resin is determined by component analysis. The substance of each component and the black material can be used to determine the specific gravity of the two substances. Therefore, the ratio of the obtained weight ratio to the respective components can be used to determine the volume of the black material in the second black film of the present embodiment. In the second black film of the present embodiment, the average dispersed particle diameter of the black material in the film is preferably 1 nm or more and 丨〇〇 nm or less, but preferably 2 nm or more and 80 nm or less. If it is 5 nm or more and 5 〇 nm or less, it is more preferable. If the average dispersed particle diameter in the film is 丨〇〇 nm or less, Rayleigh scattering in the infrared region due to the presence of fine particles of a black material can be suppressed. Or Mie scattering can suppress the decrease in the transmittance of infrared rays. That is, as described below, the black material in the present embodiment has light transmittance in the infrared region, but as before, if it is only dispersed in the resin When the average primary particle diameter of the metal fine particles is in the range of i nm or more and 2 〇〇 nm or less, the Rayleigh scattering or the Mie scattering generated in the infrared region cannot be suppressed, and as a result, sufficient infrared transmission cannot be obtained. However, in the present embodiment, Rayleigh scattering or Mie scattering is suppressed by setting the average dispersed particle diameter in the black film to 100 nm or less, and sufficient transmission characteristics can be obtained in the infrared region. In the optical element, in order to prevent the influence of Rayleigh scattering or Mie scattering of visible light, it is generally considered that the average dispersed particle diameter of the dispersed fine particles is preferably 20 nm or less. However, Rayleigh scattering or Mie scattering has a wavelength based on the generating mechanism thereof. Dependence, so compared to visible light longer wavelength infrared 157917. Doc -51- 201219465 In the case of the line, the allowable particle size is enlarged, and the infrared transmittance in the present embodiment does not require a high degree of transmission of the optical element, and allows slight scattering, so that the average dispersed particle size can be Expand to 1〇〇nm. On the other hand, the average dispersion enthalpy of the black material in the film in the present embodiment is 1 nm or more. The reason for this is that the crystallinity of the particles is lowered when the average particle diameter is less than 1 (10), so that the absorption state of visible light may become unstable, and sufficient blackness may not be obtained. The average dispersed particle diameter of the black material in the infrared-transmitting black medium in the present embodiment can be obtained by using a FIB (focused ion beam) or the like to cut the obtained infrared-transmissive black film into a sheet shape in the cross-sectional direction, using a transmission electron microscope. (TEM, Transmission Electr〇n Micr〇sc〇py) was obtained by observing the particles of the black material in the sheet. In other words, a specific number (usually 10 or more) of particles is randomly selected from the TEM photograph to measure the particle diameter, and the average value thereof may be an average dispersed particle diameter. Further, since the particles of the present embodiment are substantially spherical, the maximum diameter of each particle may be set to the particle diameter of the particles. - Black material - As the black material in the present embodiment, it is preferable to select metal fine particles containing silver and tin as main components. Here, the term "silver and tin as main components" means at least metal fine particles. Two kinds of silver and tin are contained, and the total content of silver and tin is 5% by mass or more based on the total amount of the metal fine particles. In other words, the component and the content are defined relative to the entire metal fine particles, and the components and contents of the respective particles are not specified. Metal microparticles having a particle size of 1 nm to several hundreds nm have been known (Neil 157917. Doc •52·201219465 meters of metal microparticles) exhibit various tones by absorption by surface plasmons of metal. It is also known that the color tone (ie, absorption wavelength) varies depending on the composition or particle size of the metal microparticles. . In the present embodiment, it is preferable to select a metal fine particle which exhibits a black color in the visible light region and a transmittance of a certain value or more in the infrared light region by adjusting the composition or the particle diameter. Silver and tin as the main component of the metal particles. As the metal fine particles containing silver and tin as main components, silver tin alloy fine particles or mixed fine particles of silver tin alloy fine particles and silver fine particles can be preferably used. Here, in the case where the metal fine particles containing silver and tin as main components are silver tin alloy fine particles, the content ratio of the silver component in the silver tin alloy fine particles, that is, the ratio of the silver component to the total amount of silver and tin ( Silver/(silver+tin): mass%) is preferably 45 mass% or more and 95 mass%. More preferably, it is 50% by mass or more and 95% by mass or less, and more preferably 6% by mass or more and % by mass. /〇The following. When the metal fine particles containing silver and tin as main components are fine particles of silver tin alloy fine particles and silver fine particles, the content of the silver component in the mixed fine particles of the silver tin alloy fine particles and the silver fine particles, that is, the silver component The ratio (silver/(silver + tin): mass%) relative to the total amount of silver and tin is preferably 45 mass%. Above, 95 quality. More preferably, it is 50% by mass or more and 95% by mass or less, and more preferably 6% by mass or more and % by mass or less. The reason why the content ratio of the above silver component is limited to the above range is that if 157917. Doc •53·201219465 When the ratio of the silver component is 45 mass% or more and 95 mass% or less, the reflectance of visible light does not become high, and a black film having a sufficient blackness is obtained, and sufficient light blocking property can be obtained. And the black film also has infrared transmittance. Further, when the preferred content range of the silver component is a predetermined amount of the silver tin alloy fine particles or the mixed fine particles of the silver tin alloy fine particles and the silver fine particles, the preferred content range of the silver component in the entire fine particle portion is indicated. The person's are not intended to indicate a preferred range of content of the silver component in each particle. Further, in the present embodiment, the above-mentioned so-called silver-tin alloy fine particles are not limited to the crystal structure of the silver-tin alloy, and it is possible to clearly determine that the silver-tin alloy has a crystal structure having silver. First, as an example of a crystal structure having a silver-tin alloy, it is known that when a silver-tin alloy is represented by a chemical formula Agl_xSnx (X is a real number), the range of χ is 0. 118SXS 0. Phase 2 and 〇 of 2285. 237g XS 0. ε phase of 25 (according to Binary Alloy Phase Diagram, ρ.  94-97). Further, as a crystal structure having silver, one of the silver atoms in the silver crystal is replaced by a tin atom while maintaining the structure of the silver crystal, but it is expressed as an (Ag) phase in the above literature. It is considered that when the chemical formula AgiYSnY (Y is a real number) indicates a silver-tin alloy having the silver crystal structure, γ is 〇. &lt;Y^ 0.115. Further, in the above chemical formula, Y = 0 (AgiSn()) corresponds to the silver single phase, that is, corresponds to the silver fine particles, and therefore is excluded from the range of the above-defined Y which is defined as the silver tin alloy fine particles. However, as the metal fine particles mainly containing silver and tin as the main component of the 157917.doc -54·201219465 black material, silver tin alloy fine particles or mixed fine particles of silver tin alloy fine particles and silver fine particles are preferable. Therefore, the black material may also include γ=0. Further, the black material containing the silver tin alloy fine particles or the mixed fine particles of the silver tin alloy fine particles and the silver fine particles contains substantially no tin fine particles. Here, the term "substantially free of tin fine particles" means that the presence of a substance having a crystal structure of tin is not confirmed in the analysis by the X-ray diffraction method. When the black material contains tin fine particles, the light blocking property of the black light-shielding film formed using the black material is drastically lowered. The method for producing the black material in the present embodiment is not particularly limited as long as the composition and the particle diameter are obtained, and a gas phase reaction method, a spray pyrolysis method, a liquid phase reaction method, or a cold method can be applied; Metal microparticle synthesis method such as method or hydrothermal synthesis method, but especially when silver tin alloy fine particles or mixed fine particles of silver tin alloy fine particles and silver fine particles are selected as a black material, it is preferable to use the metal microparticles. A liquid phase reaction method such as microparticles. As the liquid phase reaction method, it is preferred to use an aqueous reaction system, for example, a method in which a silver compound solution is dropped into a tin colloidal dispersion, a method of alloying tin with silver, or a dispersion in which silver colloid and tin colloid coexist. Silver tin alloy fine particles and silver fine particles are formed by adding an oxidizing agent or a reducing agent to the method of alloying silver with tin. In the production method, the reaction conditions (for example, 'the ratio of tin to silver (silver ion), the enthalpy of the reaction liquid, the reaction temperature, the reaction time, the kind or amount of the oxidizing agent or the reducing agent, etc.) are appropriately adjusted. The amount of silver-tin alloy fine particles generated, the amount of silver fine particles generated 157917.doc -55-201219465 (including the case where substantially no silver is formed, that is, only silver-tin alloy fine particles are formed), and then silver-tin alloy fine particles and The ratio of the amount of silver particles produced. Further, in order to uniformly disperse the black material in the resin component or to improve the affinity between the black material and the resin component, it is preferred to treat the surface of the black material with a surface treatment agent or a dispersant in advance. These surface treatment agents or dispersing agents may be selected from known ones depending on the material of the resin component or the method of dispersing the black material in the resin component, but as described below, the s agent or dispersing agent at the surface may be adjusted. In the same manner, the second black film of the present embodiment was obtained by adjusting the dispersion method or the dispersion conditions and allowing the black material to be well dispersed in the resin component. The dispersant is preferably a polymer dispersant, and examples thereof include a urethane dispersant, a modified polyester dispersant, a polycarboxylate 'polyalkyl sulfate, and polyvinylpyrrolidone. (pvp), polyvinyl alcohol (pVA), polyacrylamide, etc. Further, when a black film is formed by curing a resin component (a component for forming a resin component) by the following black resin composition, it can be maintained. A polymer dispersant having a preferred structure of dispersibility of a black material, which may be selected from a random copolymer, a comb-shaped copolymer, a fluorene copolymer, a BAB copolymer, a polymer having a hydrophilic group at both ends, and a terminal A polymer having a hydrophilic group or the like is considered to have a high compatibility with a solvent having high compatibility with a resin component or a resin-forming component, in other words, a resin component, a resin component, a resin component, and a resin component. When the dispersibility of the black material in the solvent having high solubility is high, a random copolymer and a comb-shaped copolymer are preferable. 157917.doc -56-201219465 Specific examples of the dispersing agent include EFKA (manufactured by EFKA Chemicals BV (EFKA) Co., Ltd.), Disperbyk (manufactured by BYK-Chemie Co., Ltd.), Disparlon (manufactured by Nanmoto Chemical Co., Ltd.), and SOLSPERS (Zeneca). Manufactured by the company, KP (manufactured by Shin-Etsu Chemical Co., Ltd.), p〇iyfi〇w (manufactured by Kyoeisha Chemical Co., Ltd.), etc. Further, examples of the surface treatment agent include a coupling agent such as a decane coupling agent and a titanium coupling agent. The black material has a high degree of blackness due to the properties of the material itself, is excellent in light-shielding properties of visible light, and has infrared transmittance. Further, by controlling the dispersed particle diameter, the scattering of infrared rays by the particles is also suppressed. Further, since it is made of an inorganic material, the chemical stability is also high, and there is no fear of fading or the like even when exposed to ultraviolet rays such as sunlight or fluorescent lamps. &lt;Resin component - Any one of the inorganic resin and the organic resin may be used as the resin component, if the black material is dispersed and there is no strong absorption in the wavelength region of the infrared ray to be used. Although it is not particularly limited, an organic resin such as an acrylic resin, an epoxy resin, a polyester resin, or a polyurethane resin, and a liquid crystal or a mems (^^〇electromechanical, MEMS) can be preferably used. System) Resinizing the mouth and the like with a photoresist. Further, X ‘ may be added with a filler containing an inorganic substance for increasing the hardness of the film or for adjusting the film = refractive index, or an additive for improving the adhesion to the coated substrate.乍 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 丙烯酸 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' The choice of monomers, oligomers, and prepolymer-based polymers. Examples of the polymer include decyl poly(meth)acrylate, cyclohexyl poly(meth)acrylate, polyethylene glycol di(meth)acrylate, and poly-trimethylolpropane di( A (meth) acrylate resin such as fluorenyl acrylate or poly-pentaerythritol tetra(meth) acrylate. Here, "(meth)acrylate" means "acrylate or methacrylate". The same is true below. Moreover, examples of the epoxy resin include glycerin polyglycidyl ether, pentaerythritol polyglycidyl ether, diglycerin polyglycidyl ether, polyglycerol diglycidyl ether, and phenol novolak type epoxy resin. Cresol novolak type epoxy resin, bisphenol type epoxy resin, trisphenol decane type epoxy resin, copolymer of glycidyl (mercapto) acrylate and styrene epoxy resin, glycidyl group Copolymer epoxy resin, styrene and (meth)acrylic acid 曱s曰 copolymer epoxy resin, glycidyl (fluorenyl) acrylate and cyclohexyl maleimide copolymer epoxy resin, and lanthanide ring Oxygen resin, etc. The polyester-based resin is not limited as long as it is usually used as a coating material, and examples thereof include polycarboxylic acids such as adipic acid, sebacic acid, and isophthalic acid, and ethylene glycol and trishydroxypropylpropane. A condensation polymer of a polyol or the like. Further, the polyurethane resin is not limited as long as it is usually used for a coating material. For example, a polyamino phthalate resin in which an isocyanate group and a polyol are chain-extended is preferred. The polyhydric alcohol may, for example, be a polyester polyol, a polyether polyol or an acrylic polyol. - Other components - The second black film of the present embodiment may contain various components such as a filler in addition to the above-mentioned black material and resin, 157917.doc -58 - 201219465. The filler may be used for the purpose of increasing the hardness of the black film or adjusting the refractive index. As the filler, an inorganic substance, particularly an inorganic oxide, is preferable and preferable. The dispersed particle diameter of the filler must not cause scattering of infrared rays. Therefore, the average dispersed particle diameter in the black film is preferably (10) or less. As the filler for increasing the hardness of the black film, an inorganic oxide having a refractive index equivalent to that of the resin component is preferable, and in terms of easiness of obtaining or price, etc., it is preferable to make the stone (two) Oxide eve) microparticles. In the case of adjusting the refractive index, for the purpose of increasing the refractive index, for example, a fine particle containing a high refractive index material such as zirconia or titania may be used, and a low refractive index may be used. In the case of the purpose, for example, it is only necessary to use fine particles having a low refractive index such as a nanoporous vermiculite or a hollow vermiculite. Further, in the black film of the second embodiment of the present embodiment, the fine particles composed of the silver tin alloy fine particles and the silver fine particles used as the black material are blacker than the carbon black or titanium black used as the black material in the previous spot color film. It is higher, so as described above, the content in the film can be reduced to a range of 1.0% by volume or more and 25% by volume or less. Therefore, even if a substance other than a black material is added, the film formation property or the characteristics of the film itself can be maintained, so that such a filler can be added. - Method for Producing Black Film - The second black film of the present embodiment is formed by molding the following black resin composition into a layer on a substrate. Further, the black resin composition of the present embodiment contains at least the resin composition of the black material, the resin-forming component or the resin component of the present embodiment, and includes a black paint or the like. 157917.doc 59·201219465 The substrate to be used is not particularly limited as long as it is selected according to the method of use or the form of use of the black film. For example, except for an inorganic substrate such as glass, the hardness is as high as that of an acrylic substrate or a polycarbonate substrate. A higher substrate 'is a structure having an infrared transmission black film. Also, if PET (polyethylene terephthalate), or PEN (Polyethylene Naphtahalate, polyethylene naphthalate), PES ((Polyethylene sulfone 'polyphosphorus), TAC (triacetyl cellulose, triethyl) A polymer film or the like which is a cellulose film or the like can also obtain a flexible infrared ray transmitting black film. The method of applying the black resin composition (coating film forming method) is also not particularly limited. Coating method, flow coating method, spray coating method, dip coating method, film coating method, gravure coating method, knife coating method, bar coating method, inkjet method, etc. by hardening or making the obtained coating film When the solvent is volatilized and removed, a second black film can be obtained. Further, when the black film is obtained by curing, when the black resin composition contains a solvent, the solvent in the coating film is first removed to form a coating. A cloth-dried film (a film-like form which becomes a solid by removing a solvent, and hardening of the resin component hardly occurs, and the film which is re-dissolved in a solvent by contact with a solvent) is hardened, and the coating film is hardened. As hardening In the method, the temperature at which the thermal polymerization is started can be heated to the monomer, the oligomer, and the prepolymer of the resin component raw material, and when the addition reaction starts to be in the form of a clear shape, as long as the reaction initiator is reacted It is sufficient to apply heat or light. In addition, the coating film of the black resin composition containing the ultraviolet ray-sensitive resin component 157917.doc 201219465 is irradiated with ultraviolet light (exposure). The process of developing and obtaining a complicated shape is briefly described. The exposure method is not particularly limited. If it is a flat shape, exposure can be easily performed by using a commercially available ultraviolet exposure device and a photomask. The ultraviolet laser can be used as a light source to scan the fine laser beam, thereby directly engraving the pattern into the coated dry film, that is, direct writing (straight engraving). The development method is also not particularly limited, as long as the dipping type is used. Or a usual method such as stirring, etc. Further, the conditions of the exposure or development are as long as the raw materials of the resin components used or the desired shape are suitable. As a preferred example of the resin composition raw material, for example, a photoresist material is used for exposing and developing the coated dry film to obtain a complicated shape, and the following black matrix is exemplified. &lt;Black material dispersion liquid and black resin composition&gt; The black material dispersion liquid and the black resin composition for forming the second black film of the present embodiment can be obtained, for example, as follows. First, prepare black materials. As the black material, the above-mentioned metal fine particles containing silver and tin as main components are preferable, and in particular, fine particles composed of silver tin alloy fine particles and silver fine particles can be more preferably used. Further, as for the production method thereof, for example, a liquid phase reaction method as described above is also preferably used. Here, the metal (in the black) is mainly composed of a metal having a hydrophilic surface as well as a liquid phase reaction method which can be preferably produced by a liquid reaction system. Therefore, in order to uniformly mix such a black material in the raw material of the resin 157917.doc 201219465, it is necessary to be directly dispersed in the state of the resin component raw material, or to disperse the black material in a high compatibility with the resin forming component or the like. In the solvent. Therefore, it is preferred to subject the black material to a surface treatment using a polymer dispersant or a surface treatment agent. In the following description, the polymer dispersant and the surface treatment agent are collectively referred to as "polymer dispersant or the like". Moreover, the said resin component raw material is as follows. In the surface treatment, the amount of the polymer dispersant or the like bonded to the surface of the black material is preferably 5% by mass or more and 3% by mass or less based on the total amount of the black material. Further, there is a better range depending on the composition of the black material or the primary particle diameter and the composition of the following resin component raw materials in which the black material is dispersed and mixed. The reason for this is to form a coating film from a black resin composition formed using the black material, and to form an infrared-transmitting black film, in order to ensure the dispersibility of the black material in the coating film or in the black film. It is necessary to strictly adjust the amount of the polymer dispersant equal to the amount added in the black material in advance. That is, when the amount of the polymer dispersant or the like is small, there is a case where a small amount of the polymer dispersant or the like is generated in one of the surfaces of the black material particles, and the resin component raw material or solvent in the portion is affinity. Sexual reduction. Further, since the black material particles remain in affinity with each other, the black material is dispersed in the resin component raw material or the solvent, and a part of the black material particles having a small amount of coating from the polymer dispersant or the like is agglomerated. On the other hand, when the amount of the polymer dispersant or the like is too large, the dispersant itself may be a factor that lowers the dispersibility. In addition, when the fat-forming component of the tree 157917.doc-62·201219465 is hardened to form a black film, there is an excessive polymer dispersant or the like which inhibits the curing by polymerization of the resin-forming component, and a sufficient film cannot be obtained. The situation of strength. Further, when a photoresist or the like is used for the cured resin, the development property in the development step after exposure with light is also cited as a reason. In order to strictly adjust the amount of the polymer dispersant to be added to the black material, it is preferred to add a polymer dispersant or the like to the aqueous solvent in which the black material particles having a hydrophilic surface are dispersed, and to impart a drop or the like. After the surface of the particles is subjected to a coating treatment such as a polymer dispersant, the solvent is removed by, for example, evaporation, and the black material particles are dried. In this manner, a sub-dispersant or the like can be added to the black material particles.里心门刀进: 'Even when it is surface-treated with a polymer dispersant or the like, it disperses and treats the unevenness of the sentence, so that the surface-treated black material particles are dispersed in the resin component raw material and the tree is eight κ The adsorption and desorption of black material particles by a solvent such as a weight dispersant in a solvent having a high raw material amount: a dispersing sword of a scorpion, etc., and a coating of each particle, thereby ensuring, and, Uniform dispersion. On the other hand, in the surface treatment, if the white-stopping treatment method is used, it is not preferable. In the treatment method, the polymer dispersant is added to the aqueous solvent having the hydrophilic surface, and the black material is coated and processed. In the case of a face-to-face lamp, a molecular dispersant, etc., or a centrifugal separation, etc. will be coagulated by coating treatment. 157917.doc •63·201219465 The black material particles of the polyprecipitate are separated from the solvent, and the Drying is carried out to carry out surface treatment using a polymer dispersant. Alternatively, the particles subjected to the coating treatment with the polymer dispersant are directly extracted and dispersed in a nonaqueous solvent in an aqueous system or a polar solvent to carry out solvent substitution. However, in these methods, a part of the polymer dispersant or the like remains in the separated aqueous solution, so that the amount of the polymer dispersant or the like is less than the designed amount. Therefore, as described above, there is a possibility that problems such as aggregation of black material particles with each other may occur. Further, since it is difficult to estimate the amount of the polymer dispersant or the like remaining in the solution, it is difficult to additionally add a corresponding amount of the polymer dispersant or the like, and if the amount is small, the amount of the polymer dispersant or the like is insufficient. The problem cannot be solved. On the other hand, when the amount of addition is excessive, the amount of the polymer dispersant or the like is excessive, which may cause problems such as curing of the resin-forming component. Further, the amount of water in the coloring material which has been surface-treated by the obtained polymer dispersant or the like is preferably 2 (% by mass or less)* with respect to the treated particles. The reason for this is to prevent the aggregation of the black material particles or the whitening of the resin, etc., in the case where the resin-shaped μ-hardened external-transmissive black film is formed by the black resin composition shape m ^ described below. In the case where the solvent and the water having a higher phasing purity with the resin d are contained together in the coating film, there is a case where the moisture content is relatively increased by drying and removing the solvent having high compatibility with the resin component raw material. When the value exceeds a certain value, the solubility parameter in the coating film largely changes, causing a phenomenon in which the particles are agglomerated or the resin is whitened. The reason is that in order to prevent this problem of 157917.doc •64·201219465, it is necessary to reduce the moisture content of the black resin composition in advance, and it is preferable to use the surface treatment of the polymer dispersant or the like which is most likely to cause moisture mixing. , try to reduce the amount of water in the black material. As a method of reducing the amount of water of the black material which is subjected to the surface treatment using such a polymer dispersant or the like, a method of removing only the solvent, for example, a method of drying the black material particles using an evaporator or the like, may be preferably used. . 〃 / On the other hand, for example, there is also a method of removing the moisture by subjecting the surface-treated black material to heat for a long time by using a dryer of 15 〇 or more'. However, in this case, the low molecular dispersant volatilizes or Decomposition, which causes a change or deterioration in the amount of the dispersant, is therefore poor. Next, a black resin composition containing a black material surface-treated with a polymer dispersant or the like and a resin component raw material is produced. Here, the resin component raw material is a liquid component, and the resin component is formed by curing or solvent distillation, and includes a monomer, an oligomer, and a prepolymer (resin forming component) which form a resin component. The method further includes dissolving a resin component in a solvent, and further including dissolving a monomer, an oligomer, and a prepolymer which form a resin component in a solvent. When the monomer, the oligomer, and the prepolymer which form the resin component are in the form of a liquid, the monomer, the oligomer, and the prepolymer may be directly used as a resin component raw material to mix and disperse the black material therein. And a black resin composition was produced. Further, the resin component or the solid monomer, the oligomer, and the prepolymer may be dissolved in a suitable solvent to form a liquid solution, or the above-mentioned monomer, oligomer, and prepolymerized in a liquid state. A solution obtained by diluting a solvent in a solvent 157917.doc -65 - 201219465 as a raw material of a resin component, in which a black material is mixed and dispersed to prepare a black resin composition. Further, the black paint may include the above filler or the following additives. In the present embodiment, the black material which has been surface-treated with a polymer dispersant or the like may be mixed and dispersed in a state of fine particles in a resin component raw material to form a black resin composition, or may be prepared in advance. A black material dispersion liquid (hereinafter referred to as a "dispersion liquid") in which a black material is dispersed in a solvent having high compatibility with a resin component raw material, and the dispersion liquid is mixed with a resin component raw material to form a black color. Resin composition. Further, in the black material dispersion, the above filler may be dispersed in advance, or the following additives may be dissolved in advance. The black material in the black resin composition or the black material dispersion has an average dispersed particle diameter of 100 nm or less, preferably 50 nm or less. The average dispersed particle diameter of the black material in the black film produced using the coating or dispersion can be controlled to 1 by setting the average dispersed particle diameter in the black resin composition or the black material dispersion to 1 〇〇 nm or less. Below 〇〇 nm, as a result, the decrease in the transmittance of infrared rays due to Rayleigh scattering or Mie scattering in the infrared region is suppressed. Further, the above-mentioned average dispersed particle diameter can be measured by using a particle size measuring device (for example, Microtrac 9340-UPA, manufactured by Nippon Machine Co., Ltd.) using a dynamic light scattering method to determine the particle size distribution of the prepared black resin composition or the like. It is 5 〇 number on the small particle size side of the number distribution. Find the value of Λ. As the resin component raw material, a monomer, an oligomer, and a prepolymer (resin forming component) which form a resin component can be preferably used. 157917.doc -66- 201219465 Examples of the monomer of the acrylic resin include methyl (meth) acrylate, cyclohexyl (decyl) acrylate, and ethylene glycol di(decyl) acrylate. Diethylene glycol di(meth)acrylate, triethylene glycol di(meth)acrylate, tetraethylene glycol di(meth)acrylic acid vinegar, trimethyl methacrylate tris(sub)acrylic acid Ester, trimethylolethane tri(meth)acrylate, pentaerythritol tetra(meth)acrylate, dipentaerythritol hexa(meth)acrylate, and glycerol (mercapto)propionate vinegar Acrylic acid g; 2 - hydroxy group-containing monoethyl (meth) acrylate, 2 hydroxypropyl (meth) acrylate, and 2-ethylhexyl (meth) acrylate And a polyester compound, an amino phthalate compound, a bisphenol (meth) acrylate compound, and a fluorenyl (meth) acrylate compound, etc., as an oligomer or prepolymer For example, poly(methyl) methacrylate, poly(meth)acrylic acid cyclohexanone, polyethyl b A poly(meth) acrylate resin such as diol di(indenyl) acrylate, poly-trimethylolpropane tris(meth) acrylate, or poly-pentaerythritol tetra(indenyl) acrylate. Further, as the acrylic resin, for example, "ACRYDIC"-based "fired-type acrylic resin" manufactured by DIC (Stock Co., Ltd.) can be used. Further, examples of the monomer, oligomer, and prepolymer of the epoxy resin include glycerin polyglycidyl ether, pentaerythritol polyglycidyl ether, diglycerin polyglycidyl ether, and polypropylene glycol diglycidyl ether. , phenol novolak type epoxy resin, nonylphenol novolak type epoxy resin, bisphenol type epoxy resin, lanthanum epoxy resin, trisphenol decane type epoxy resin, glycidyl (fluorenyl) acrylate vinegar Copolymer of styrene, epoxy resin, glycidyl group (曱157917.doc •67·201219465) propylene oxime and copolymer of stupid ethylene and methyl (meth) acrylate a copolymer of fluorenyl acrylate and cyclohexylmaleimide, a prepolymer such as a oxy-resin or the like before crosslinking. In the present embodiment, as described below, the coating-dried film can be exposed and developed to form a black film having a complicated design or an improved shape. The resin-forming component preferably has ultraviolet rays. Photosensitive J·sheng. Further, by using a resin-forming component having ultraviolet ray sensitivity, it can also be used as a black photoresist for forming a black pattern. Here, as the resin having ultraviolet ray sensitivity, there are a negative type (developing and leaving the photosensitive portion) and a positive type (removing the photosensitive portion by development), but it is preferably a negative type. The reason is that the black film or the black material of the present embodiment has a light-shielding property against ultraviolet rays. Therefore, in the exposed portion (ultraviolet irradiation portion), the bottom β of the film is liable to become insufficiently light-sensitive, and in the case of a positive type. At the time, it becomes easy to generate a residual film', so it is preferable to prevent the influence from being negative. The resin component having ultraviolet ray sensitivity may be a commercially available photoresist material, or may be used in the above acrylic resin, epoxy resin, polyester resin, or polyurethane resin. A photoreactive agent is added. As the commercially available photoresist material, those using liquid crystal or MEMS are preferably used because they are formed into a permanent film by heat-hardening a film formed of the photoresist materials. . As the above-mentioned commercially available photoresist compound, for example, "Lipoxy" PR series, SPC series manufactured by Showa Polymer Co., Ltd., or "ZCR1569H" manufactured by Sakamoto Chemical Co., Ltd., or the like can be used. Further, it is more preferable to use a light 157917.doc-68-201219465 resist component (other than a pigment) which is a commercially available pigment-dispersed photoresist for forming a black matrix of liquid crystal or a color filter. Further, a reaction initiator for curing the resin component raw materials may be added to the black resin composition. The reaction initiator is a substance which initiates/promotes the polymerization of the resin component by generating a radical by heat or light. Examples of the photoreaction initiator include Ciba Specialty.

Chemicals' Darocure series (eg i173, etc.), or irgacur4 columns (eg 651, 184, 908, 2959, OXE01, OXE02, etc.). These may be used alone or in combination of two or more. Thus, by making the resin-forming component photocurable, the resin-forming component can be regarded as a negative-type photoresist. The solvent used for the resin component raw material or the solvent used for the black material dispersion liquid is not particularly limited as long as it can maintain the solubility of the resin component (raw material) to be used and the dispersibility of the black material, and for example, : sterol, ethanol, ethylene glycol monomethyl ether, ethylene glycol monobutyl ether 'ethylene glycol monoethyl ether, propylene glycol monomethyl ether, propylene glycol monobutyl ether, propylene glycol monoethyl ether, propylene glycol monomethyl ether acetate, methyl Ethyl ketone, decyl isobutyl ketone, and the like. Further, it is a matter of course that the solvent used for the resin component raw material and the black material dispersion liquid has sufficient compatibility, but when the solvent component raw material contains a solvent, the solvent and the solvent in the black material dispersion liquid are also Need sufficient compatibility. In the case where the compatibility is insufficient, when the black resin composition is prepared by mixing the two, there is a possibility that aggregation or precipitation of the black material or unevenness of the coating material may occur. The mixed dispersion for obtaining the above black resin composition or black material dispersion can be carried out by using an ultrasonic disperser, a coating, a 157917.doc, a 69·201219465 ball mill, a bead mill, and an EGGER grinder ( E coffee is prepared by a well-known mixing disperser, and the dispersion condition of the average dispersion particle of the above-mentioned black material is obtained, and the mixture of the black material and the resin component raw material or solvent is dispersed. Further, the black material is mixed. In addition to the addition of a solvent for adjusting the viscosity or dispersion state, or the addition of the above-mentioned filler or curing agent, the addition of a low molecular weight crosslinking agent for increasing the hardness of the film may be performed. A broth coupling agent or the like for improving the adhesion between the formed infrared ray transmitting black film and the coated substrate is not added to the range in which the characteristics of the formed infrared ray transmitting black film are deteriorated. The substrate having a film&gt; As described above, since the second black film of the present embodiment is formed on a suitable substrate, the second black film is formed. A substrate having a film containing an infrared ray transmitting black film can be obtained on the substrate. The substrate can be similarly used for the substrate described in the above-mentioned black film formation. A flat panel, a film, a sheet, etc. A wireless remote controller or the like can be obtained by subjecting the substrate to a desired shape in advance or by molding a obtained substrate having a film containing an infrared ray transmitting black film. Further, if a black film is formed in a matrix pattern on a substrate, a black matrix can be obtained. Further, the shape of the substrate and the form of the black film are not formed on the substrate. All of the black film are included in the film-attached substrate of the present embodiment. <Image display device> The second black film having infrared transmittance in the present embodiment can preferably be 1579l7.doc • 70- 201219465 is used as a constituent element constituting a display element or the like in the image forming apparatus. That is, the image display device of the present embodiment may have a black film of the present embodiment in the device, and the aspect thereof may be The substrate including the film of the present embodiment may be other than the above, and the image forming apparatus may be a magnetic display display device, an EL display device, a CRT display device, or a liquid crystal display device. In the case of being used in a liquid crystal display device or an EL display device, the effect of the black film of the present embodiment can be remarkably exhibited. For example, as described above, a black paint can be formed by using a resin-forming component having ultraviolet light sensitivity. It is used as a pigment dispersion resist (black photoresist) for forming a black matrix or a color filter as a liquid crystal. Further, the second black film of the present embodiment formed thereby can be used as an image of a liquid crystal or the like. A black matrix or a color filter is used for the display device. That is, after the coating dry film using the black paint is formed on the black matrix substrate, a black matrix pattern is formed by exposure and development, and further, by heat curing or the like. When the black matrix pattern is hardened and permanently formed, a black matrix using the infrared ray transmitting black film of the present embodiment can be produced. Further, a color filter can be produced by combining the black matrix pattern with the color filter element/pattern.

Further, it was confirmed that even if the content of the black material in the film or the film thickness itself was changed, the dispersion particle diameter of the black material or the transmission characteristics at each wavelength did not differ, and the high visible light shielding property and the excellent infrared transmission were maintained. Therefore, it was confirmed that the density of the black filter can be adjusted by controlling the content of the black material in the film or the film thickness itself. On the other hand, in Comparative Examples B i to B4, the transmittance in the visible light region and the infrared ray region did not change much, and the transmittance in the infrared ray region was not obtained. In the case of Comparative Example B5, the amount of the polymer dispersant added was too small. ～~ The black powder could not be sufficiently dispersed, and the dispersion could not be prepared. In addition, in Example B6, the amount of the polymer dispersant added was too large. However, the dispersion state is unstable. Therefore, the black powder is agglomerated when a black medium is formed, and a good black film cannot be obtained. Further, in a relatively fine manner, the affinity between the black powder and the polymer dispersant is poor. The molecular dispersant was sufficiently coated. Therefore, the dispersibility of the black powder itself was poor, and the dispersion could not be prepared. Further, in Comparative Example B8, the amount of water in the black powder was too large, so when a black film was formed (solvent ritual) When it is white, it is presumed that the reason is that the solvent having good compatibility with the T 含有 phase is less, and conversely, the water having poor compatibility is relatively increased, so that a part of water is precipitated in the resin, and the film is Appearance looks white.
