Description

  The present invention relates to a photopolymerizable composition, a color filter and a method for producing the same, a solid-state imaging device, and a lithographic printing plate precursor.

Examples of the photopolymerizable composition include those obtained by adding a photopolymerization initiator to a polymerizable compound having an ethylenically unsaturated bond. Since such a photopolymerizable composition is polymerized and cured when irradiated with light, it is used in photocurable inks, photosensitive printing plates, color filters, various photoresists, and the like.
Moreover, as a photopolymerizable composition, there exists another aspect which generate | occur | produces an acid by irradiation of light, for example, and uses the generated acid as a catalyst. Specifically, it is used as a material for image formation, anti-counterfeiting, detection of energy dose by utilizing the coloring reaction of the dye precursor with the generated acid as a catalyst, or the decomposition reaction with the generated acid as a catalyst. Is used for positive resists for semiconductor manufacturing, TFT manufacturing, color filter manufacturing, micromachine component manufacturing, etc.

For example, in forming a color filter for LCD, a pigment resist having only dipentaerythritol hexaacrylate (hereinafter referred to as “DPHA”) as a monomer has been used (see, for example, Patent Document 1). However, when DPHA is used, a pigment resist that should be removed by an alkaline developer during development sometimes remains on the substrate as a residue.
In order to reduce such residues, it has been proposed to use a monomer having an acid group with an acid value of 25 mgKOH / mg instead of DPHA (see, for example, Patent Documents 2 and 3).

However, even when the monomer component specifically described in Patent Documents 2 and 3 (TO1382; manufactured by Toagosei Co., Ltd.) is used, when the pigment is used at a high concentration of 35% or more, the residue is still reduced. There was a problem that was not improved.
Furthermore, the color filter for image sensors has a pixel size of about 5 μm in the late 1990s due to a demand for improving the resolution of a solid-state imaging device such as a CCD. It is about to become smaller. Therefore, as the pixels become smaller, the contact area between the pigment resist surface in the unexposed area and the alkaline developer becomes smaller, and the residue of the pigment resist due to poor dissolution of the pigment resist in the alkaline developer occurs, resulting in a taper in the pattern shape. Increased. In addition, the sensitivity of adjacent pixels decreases due to the occurrence of residue, and color mixing with adjacent pixels and gaps between pixels occur due to increased taper, resulting in increased noise and roughness in the reproduced image of the solid-state imaging device. There is a problem that the image quality tends to be impaired, such as becoming conspicuous.

In addition, in recent years, there has been a strong demand for high color density and thinning of color filters in order to improve image quality due to high light-condensing properties and high color separation of solid-state image sensors such as CCDs, and a large amount of colorant is added to the resist. As a result, the alkali developability of the pigment resist is further lowered, and a residue is likely to be generated.

When the mass ratio is less than 100: 5, it is difficult to suppress the light transmittance of 400 nm to 450 nm, and the color purity may not be improved. When the ratio exceeds 100: 150, the dominant wavelength becomes longer and the deviation from the NTSC target hue may increase. The mass ratio is particularly preferably in the range of 100: 30 to 100: 120.

  Other preferred examples include those in which a water-resistant hydrophilic layer is provided as a surface layer on an arbitrary support. Examples of such a surface layer include a layer composed of an inorganic pigment and a binder described in US Pat. No. 3,055,295 and JP-A-56-13168, and a hydrophilic swelling described in JP-A-9-80744. Examples thereof include sol-gel films made of titanium oxide, polyvinyl alcohol, and silicic acids described in JP-A-8-507727.

  These hydrophilic treatments are performed to make the surface of the support hydrophilic, in order to prevent harmful reaction of the photopolymerizable composition provided thereon, and to improve the adhesion of the photosensitive layer. It is given for the purpose.

[Protective layer]
In the lithographic printing plate precursor according to the invention, it is preferable to further have a protective layer on the photosensitive layer. Protective layer prevents exposure to oxygen and low molecular weight compounds such as basic substances in the atmosphere that hinder the image formation reaction caused by exposure in the photosensitive layer, allowing exposure in the atmosphere And Therefore, the properties desired for such a protective layer are low permeability of low-molecular compounds such as oxygen, and further, transmission of light used for exposure is not substantially inhibited, and adhesion to the photosensitive layer is excellent. And it is desirable that it can be easily removed in the development process after exposure.

  Devices related to the protective layer have been conventionally used and are described in detail in US Pat. No. 3,458,311 and JP-A-55-49729. As a material that can be used for the protective layer, for example, a water-soluble polymer compound having relatively excellent crystallinity is preferably used. Specifically, polyvinyl alcohol, polyvinyl pyrrolidone, acidic celluloses, gelatin, gum arabic, Water-soluble polymers such as polyacrylic acid are known. Of these, the use of polyvinyl alcohol as the main component gives the best results in terms of basic properties such as oxygen barrier properties and development removability.

  The polyvinyl alcohol used for the protective layer may be partially substituted with an ester, an ether, and an acetal as long as it contains an unsubstituted vinyl alcohol unit for having necessary oxygen barrier properties and water solubility. Similarly, some of them may have other copolymer components. Specific examples of polyvinyl alcohol include those having a hydrolysis rate of 71 to 100 mol% and a molecular weight in the range of 300 to 2400 in terms of mass average molecular weight. Specifically, Kuraray Co., Ltd. PVA-105, PVA-110, PVA-117, PVA-117H, PVA-120, PVA-124, PVA-124H, PVA-CS, PVA-CST, PVA-HC, PVA-203, PVA-204, PVA-205, PVA-210, PVA-217, PVA-220, PVA-224, PVA-217EE, PVA-217E, PVA-220E, PVA-224E, PVA-405, PVA- 420, PVA-613, L-8 and the like.

  Components of the protective layer (selection of PVA, use of additives), coating amount, and the like are selected in consideration of fogging, adhesion, and scratch resistance in addition to oxygen barrier properties and development removability. In general, the higher the hydrolysis rate of the PVA used (the higher the content of the unsubstituted vinyl alcohol unit in the protective layer), the higher the film thickness, the higher the oxygen barrier property and the more advantageous in terms of sensitivity. However, when the oxygen barrier property is extremely increased, there arises a problem that unnecessary polymerization reaction occurs during production and raw storage, and unnecessary fogging and image line thickening occur during image exposure. In addition, adhesion to the image area and scratch resistance are extremely important in handling the plate. Such a coating method for the protective layer is described in detail in, for example, US Pat. No. 3,458,311 and JP-A-55-49729.

  Furthermore, other functions can be imparted to the protective layer. For example, by adding a colorant (such as a water-soluble dye) that is excellent in the transmission of light from 350 nm to 450 nm and that can absorb light of 500 nm or more, which is used for exposure, it does not cause a decrease in sensitivity. Suitability can be further enhanced.

[Other layers]
In addition, it is possible to provide a layer for improving the adhesion between the photosensitive layer and the support and for improving the development removability of the unexposed photosensitive layer. For example, the addition of a compound having a relatively strong interaction with the substrate, such as a compound having a diazonium structure or a phosphone compound, or an undercoat layer can improve adhesion and increase printing durability. The addition of a hydrophilic polymer such as acrylic acid or polysulfonic acid or the undercoat layer improves the developability of the non-image area and improves the stain resistance.

[Plate making]
The lithographic printing plate precursor is usually subjected to image exposure, and then an unexposed portion of the photosensitive layer is removed with a developer to obtain an image.

  As the exposure method applicable to the lithographic printing plate precursor according to the invention, a known method can be used without limitation. The wavelength of the light source is desirably 350 nm to 450 nm, and specifically, an InGaN-based semiconductor laser is suitable. The exposure mechanism may be any of an internal drum system, an external drum system, a flat bed system, and the like. In addition, the photosensitive layer component can be made soluble in neutral water or weak alkaline water by using a highly water-soluble component, but a lithographic printing plate having such a configuration is loaded on a printing press. Thereafter, a system such as exposure-development can be performed on the machine.

  As an available laser light source of 350 to 450 nm, the following can be used.

As a gas laser, Ar ion laser (364 nm, 351 nm, 10 mW to 1 W), Kr ion laser (356 nm, 351 nm, 10 mW to 1 W), He—Cd laser (441 nm, 325 nm, 1 mW to 100 mW), and solid laser as Nd: Combination of YAG (YVO ₄ ) and SHG crystal × 2 times (355 nm, 5 mW to 1 W), combination of Cr: LiSAF and SHG crystal (430 nm, 10 mW), KNbO ₃ ring resonator (430 nm, 30 mW) as a semiconductor laser system A combination of a waveguide-type wavelength conversion element and AlGaAs, InGaAs semiconductor (380 nm to 450 nm, 5 mW to 100 mW), a combination of a waveguide-type wavelength conversion element, AlGaInP, and an AlGaAs semiconductor (300 nm to 350 nm, 5 mW to 00mW), AlGaInN (350nm~450nm, 5mW~30mW ), other, _{N 2} laser (337 nm as a pulse laser, pulse: 0.1 to 10), XeF (351 nm, pulse 10 to 250 mJ), and the like.

  Among these, an AlGaInN semiconductor laser (commercially available InGaN-based semiconductor laser 400 to 410 nm, 5 to 30 mW) is preferable in terms of wavelength characteristics and cost.

  Further, as a lithographic printing plate exposure apparatus of a scanning exposure method, there are an inner drum method, an outer drum method, and a flat bed method as an exposure mechanism, and all of the light sources other than the pulse laser can be used as a light source. it can. Practically, the following exposure apparatus is particularly preferable in terms of the relationship between the photosensitive material sensitivity and the plate making time.

・ Single beam exposure system that uses one gas laser or solid-state laser light source in the internal drum system ・ Multi-beam exposure system that uses many (10 or more) semiconductor lasers in the flat bed system ・ Many semiconductor lasers in the external drum system Multi-beam exposure equipment used (10 or more)

In the laser direct-drawing lithographic printing plate as described above, generally the photosensitive material sensitivity X (J / cm ² ), the photosensitive material exposure area S (cm ² ), the power q (W) of one laser light source, the laser Equation (eq1) is established between the number n and the total exposure time t (s).
X · S = n · q · t Formula (eq1)

i) In the case of the internal drum (single beam) system, the laser rotation speed f (radians / s), the sub-scanning length Lx (cm) of the photosensitive material, the resolution Z (dots / cm), and the total exposure time t (s) In general, equation (eq2) holds.
f · Z · t = Lx Formula (eq2)

ii) In the case of the external drum (multi-beam) system, the drum rotation speed F (radians / s), the photosensitive material sub-scanning length Lx (cm), the resolution Z (dots / cm), the total exposure time t (s), the number of beams In general, equation (eq3) is established during (n).
F · Z · n · t = Lx Formula (eq3)

iii) In the case of the flat bed (multi-beam) method, the rotational speed H (radian / s) of the polygon mirror, the sub-scanning length Lx (cm) of the photosensitive material, the resolution Z (dot / cm), the total exposure time t (s), Equation (eq4) is generally established between the number of beams (n).
H.Z.n.t = Lx Formula (eq4)

Resolution required for actual printing plate (2560 dpi), plate size (A1 / B1, sub-scan length 42 inch), exposure conditions of about 20 sheets / hour and photosensitive characteristics (photosensitive wavelength of the photopolymerizable composition of the present invention) By substituting (sensitivity: about 0.1 mJ / cm ² ) into the above formula, it can be understood that a combination with a semiconductor laser multi-beam exposure method is more preferable in the photosensitive material of the present invention. Further, by combining operability, cost, etc., a combination with an external drum type semiconductor laser multi-beam exposure apparatus is most preferable.

  Other exposure rays include ultra high pressure, high pressure, medium pressure, low pressure mercury lamps, chemical lamps, carbon arc lamps, xenon lamps, metal halide lamps, visible and ultraviolet laser lamps, fluorescent lamps, tungsten lamps, solar Light or the like can also be used.

  Developers suitable for the lithographic printing plate precursor of the present invention include developers described in JP-B-57-7427, such as sodium silicate, potassium silicate, sodium hydroxide, potassium hydroxide. Inorganic alkaline agents and monoethanolamine, such as lithium hydroxide, tribasic sodium phosphate, dibasic sodium phosphate, tribasic ammonium phosphate, dibasic ammonium phosphate, sodium metasilicate, sodium bicarbonate, aqueous ammonia Or an aqueous solution of an organic alkaline agent such as diethanolamine is suitable. It is added so that the concentration of such an alkaline solution is 0.1 to 10% by mass, preferably 0.5 to 5% by mass.

  Such an alkaline aqueous solution may contain a small amount of a surfactant, an organic solvent such as benzyl alcohol, 2-phenoxyethanol, and 2-butoxyethanol as necessary. Examples thereof include those described in US Pat. Nos. 3,375,171 and 3,615,480.

  Further, the developers described in JP-A-50-26601, 58-54341, JP-B-56-39464, and 56-42860 are also excellent.

A particularly preferred developer contains a nonionic compound represented by the following general formula (IV) described in JP-A No. 2002-202616, has a pH of 11.5 to 12.8, and 3 Examples include a developer having a conductivity of ˜30 mS / cm.
A-W Formula (IV)

In the formula (IV), A represents a hydrophobic organic group having a log P of AH of 1.5 or more, and W represents a nonionic hydrophilic organic group having a log P of W-H of less than 1.0.
This developer component is described in detail in paragraphs (0024) to (0067) of JP-A No. 2002-202616.

  It is effective to add the nonionic compound represented by the general formula (IV) in the developing solution in an amount of 0.1 to 15% by mass, preferably 1.0 to 8.0% by mass.

  In addition, in the plate making process of the lithographic printing plate precursor, the entire surface may be heated before exposure, during exposure, and between exposure and development, if necessary. By such heating, an image forming reaction in the photosensitive layer is promoted, and advantages such as improvement in sensitivity and printing durability and stabilization of sensitivity may occur. Further, for the purpose of improving the image strength and printing durability, it is also effective to subject the developed image to full post heating or full exposure. Usually, heating before development is preferably performed under mild conditions of 150 ° C. or less. When it is 150 ° C. or lower, the problem of fogging does not occur in the non-image area. Very strong conditions are used for heating after development. Usually, it is the range of 200-500 degreeC. When the temperature is 200 ° C. or higher, sufficient image strengthening action can be obtained. When the temperature is 500 ° C. or lower, problems such as deterioration of the support and thermal decomposition of the image portion do not occur.

[5. Production and Evaluation of Color Filter Using Colored Photopolymerizable Composition B-1]
3 above. The photopolymerizable composition B-1 prepared in 1. The photopolymerizable coating film was formed by coating on the undercoat layer of the silicon wafer substrate with the undercoat layer obtained in (1). Then, a heat treatment (pre-baking) was performed for 120 seconds using a hot plate at 100 ° C. so that the dry film thickness of the coating film became 0.9 μm.
Next, using an i-line stepper exposure apparatus FPA-3000i5 + (manufactured by Canon Inc.), irradiation was performed at an exposure dose of 10 to 1600 mJ / cm ² through an Island pattern mask having a pattern of 2 μm square at a wavelength of 365 nm.
Thereafter, the silicon wafer substrate on which the irradiated coating film is formed is placed on a horizontal rotary table of a spin shower developing machine (DW-30 type, manufactured by Chemitronics Co., Ltd.), and CD-2000 (FUJIFILM Corporation). Paddle development was performed at 23 ° C. for 60 seconds using Electronics Materials Co., Ltd. to form a colored pattern on the silicon wafer substrate.

<Exposure sensitivity>
The minimum exposure amount in which the film thickness after development of the region irradiated with light in the exposure step was 95% or more with respect to 100% of the film thickness before exposure was evaluated as the exposure sensitivity. A smaller exposure sensitivity value indicates higher sensitivity. In addition, the size of the colored pattern was measured using a length measurement SEM “S-9260A” (manufactured by Hitachi High-Technologies Corporation). The closer the pattern size is to 2 μm, the better the polymerizability and the better the sensitivity.

The observed results were evaluated by classifying them into three stages of Type-A, Type-B, and Type-C in order from the most appropriate level (that is, in order from the order in which the generation of the residue is suppressed). Details of the classification method are shown in Table 2 below. Moreover, the generation | occurrence | production state of the development residue in Type-A, Type-B, and Type-C is shown in FIG.
