Electronic paper. Hereinafter, each configuration of the color filter member for electronic paper of the present invention will be described. 1. Color filter layer The color calender sheet layer used in the present invention is formed on one surface side of a color calender sheet base and includes a plurality of color layers. Furthermore, the concept of "formed on one surface side of a color filter substrate" herein includes not only the direct formation on one surface of a color filter substrate, but also the inclusion of the other. The layer is formed on the surface of one of the color filter substrates. The plurality of color layers included in the color filter layer are not particularly limited as long as they can exhibit a desired color when the electronic paper is produced using the color filter member for electronic paper of the present invention, and can be used. Colored layers of various colors used in general color filters. In the present invention, a coloring layer containing a plurality of the three colors of red (R), green (G), and blue (B) is usually used. The plurality of color layers used in the present invention are generally formed in a pattern shape in a plurality of colors. However, the pattern used in the present invention is not particularly limited. The color filter and optical sheet for electronic paper according to the present invention may be used. The purpose of the member is appropriately selected. Examples of such a graph # include a stripe type, a well-inserted type, a triangular type, and a 4-pixel arrangement type. In addition, the area of each of the colored layers is not particularly limited, and the degree of resolution of the electronic paper produced by using the color filter member for electronic paper of the present invention is appropriately adjusted. The material of the colored layer described above can be the same as that of the user of the color layer of a general color light-passing sheet, and the description herein will be omitted. The film thickness of the coloring layer used in the present invention is not particularly limited as long as it can display a good image when the color light-receiving sheet member for electronic paper of the present invention is used for electronic paper, but is not particularly limited. For example, it can be set within the range of 〇5 to 3·0 /zm. Further, as a method of forming the colored layer, there is no particular method as long as it is a method of forming a colored layer having a desired thickness without color mixing. As such a method, 100123476 11 201211592 is a generally known method such as a method of law or an inkjet method. The layer, but also optionally, the color f-layer layer has at least the other constitutions described above for the other coloring without the (10)t heart color. As a glazing sheet structure (4), the paper is formed by thinning, and the color filter substrate used in the coloring layer is used to distinguish pixels. 2. Color filter substrate is used in the present invention. The color filter substrate is a layer on the support floor and the like, and the layer of the color (four) (four) of the electronic paper of the present invention is formed; as the color filter substrate, as long as it has the desired transparency, then In particular, it is possible to use 4 towels which are the same as the moon-transparent substrate used in the general color calendering sheet, and the color light-receiving sheet substrate used in the invention has a transmittance of preferably 8 G% in the visible light region. More preferably, it is 90% or more. The reason for this is that when the color filter member for electronic paper of the present invention is used for electronic paper in the above range, the phenomenon that the display brightness is lowered or the like can be prevented. Here, the transmittance of the 'color filter substrate' can be measured by JIS K7361-l (Test method for the total light transmittance of the plastic-transparent material). The color filter substrate used in the present invention may be a transparent substrate that does not have flexibility such as a glass substrate, or may be a resin film substrate or the like having transparency of 100123476 12 201211592. Flexible substrate. Among them, in the present invention, it is preferred to use a transparent flexible substrate. The reason for this is that the color filter member for electronic paper of the present invention can be produced by a roll-to-roll method by using a transparent flexible substrate. Examples of the resin film-forming substrate include polyethylene terephthalate (PET), polyethylene terephthalate (PEN), and polyether stone (PEN). PES, w P〇ly (ether sulfones), polyimine (PI, Polyimide), polyether ether ketone (PEEK, Polyether Ether Ketone), polycarbonate (PC, Polycarbonate), polyethylene (PE, Polyethylene) , PP, Polypropylene, Polyphenylene Sulfide, PEI, Polyetherimide, Cellulose triacetate (CTA), Cyclic Polyether (COP) (Cyclic Polyolefin), a film composed of polymethyl Methacrylate (PMMA), polysulfide (PSF 'P〇lySUlfone), polyacrylamide (PAI), and the like. The thickness of the color filter substrate used in the present invention is not particularly limited, and may be appropriately adjusted according to the use of the color filter member for electronic paper according to the present invention. Specifically, the thickness of the color filter substrate is preferably in the range of 10 μm to 500 " m. The reason for this is that if the thickness of the color-based light-sensitive sheet substrate is too thin, there is a problem in strength. If the thickness of the color filter substrate is too thick, it is difficult to use the color light-emitting light for the electronic paper of the present invention. The electronic paper of the sheet member is made into a thin information display panel. 100123476 13 201211592 3. Optical functional layer The optical functional layer used in the present invention is disposed on the outermost surface of the color filter substrate on the surface side where the color filter layer is not formed, when the electronic paper of the present invention is used When the color filter member is used for electronic paper, the visibility of the electronic paper can be improved. Further, in the present invention, the optical functional layer may be a layer which also serves as a surface protective layer described below. The optical functional layer may be separately disposed on the outermost surface of the color filter substrate on the side where the color filter layer is not formed, or may be formed on the optical functional layer substrate to form an optical functional layer on the optical functional layer substrate. The form of the laminate is disposed on the outermost surface of the color filter substrate on the side where the color filter layer is not formed. As the optical functional layer substrate used in the present invention, the same color filter substrate as described above can be used. The thickness of the optical functional layer substrate is not particularly limited as long as it can support the optical functional layer, but is preferably in the range of 10 /zm to 500 ym. Further, in the optical functional layer laminate, the adhesive layer containing the adhesive is usually formed on the optical functional layer substrate side and bonded to the color filter substrate. The adhesive material may be a resin that can be adhered to a desired strength and has transparency. Examples thereof include a polycarbonate resin, a polyolefin resin, an acrylic resin, an amine ruthenate resin, and polycrystalline oxime. A resin, a polyester resin, an epoxy resin or the like is preferable, and among them, an acrylic resin is preferable. In addition, the film thickness of the above-mentioned adhesive layer is not particularly limited as long as it can be bonded so as not to peel off 100123476 14 201211592, and specifically, it can be 5 //m to 50 /zm. Set within the range. Examples of the optical functional layer used in the present invention include an antiglare layer, an antireflection layer, a low reflection layer, and a peep prevention layer. Among them, an antiglare layer and an antireflection layer are preferable. Hereinafter, the antiglare layer and the antireflection layer will be described. (1) Anti-glare layer (anti-glare layer) w The anti-glare layer used in the present invention has an anti-glare property. The antiglare layer has, for example, irregularities on the surface or internal scattering properties, and thus exhibits anti-glare properties, and can improve the contrast of bright spots. Further, since the anti-glare layer is contained, when the color filter member for electronic paper of the present invention is used for electronic paper, generation of glare or the like can be suppressed. In the present invention, a known antiglare layer can be used. The material for forming the anti-glare layer is not particularly limited as long as it has a layer having irregularities on the surface or having internal scattering properties, and examples thereof include those containing a light-transmitting fine particle and a binder component. As the light-transmitting fine particles, an organic or inorganic type can be used. In terms of ensuring the transparency of the antiglare layer, it is preferably an organic system, particularly an acrylic microparticle. The acrylic fine particles are not particularly limited, and examples thereof include a copolymer of an isocyanate-ester compound, an ester compound, and an acrylic monomer component or a monomer copolymerizable with the same. The copolymer of the acrylic monomer component and the monomer copolymerizable with the above-mentioned monomers may, for example, be a decyl acrylate-styrene copolymer. Examples of the inorganic fine particles include amorphous ruthenium, inorganic ruthenium beads, and the like. 100123476 15 201211592 The light-transmitting fine particles may be primary particles or secondary particles.

The reason for this is that if the content is less than the above range, sufficient antiglare property cannot be imparted, and if the content exceeds the above range, the film strength may be lowered. The binder component used in the antiglare layer imparts film forming properties to the antiglare layer. The binder component is preferably a curable organic resin, and is preferably one which is light transmissive when it is a coating film.

A compound having a cationically polymerizable functional group such as an oligomer such as a type epoxy compound, an aromatic vinyl ether or an aliphatic vinyl ether or a prepolymer. It is a solvent-drying type which is used in a mixture of ionizing radiation-curing type sealants. The thermoplastic lion can be used as a specific example of a thermoplastic resin which can effectively prevent the coating film of the coated surface by adding a drying agent-dried resin.

Examples of such particles include titanium oxide, oxide oxide, zinc telluride, and aluminum oxide. The antiglare layer is preferably a leveling agent containing a fluorine-based or polycrystalline oxime system. The reason for this is that coating stability, slidability, antifouling property and abrasion resistance can be imparted. The antiglare layer can be formed, for example, by applying a coating liquid for forming an antiglare layer, drying it, and hardening as necessary. The average lining of the anti-glare layer is within the range of (4) 1 to 1G a.

Surface protective layer The surface protective layer used in the present invention is disposed on the outermost surface of the color filter substrate on the surface side where the color filter layer is not formed, and is used in the electronic paper of the invention of 100123476 201211592 When the color filter member is used in the case of electronic paper, damage and contamination of the surface of the electronic paper can be prevented. Further, in the present invention, the surface protective layer may be a layer which also serves as the above optical functional layer. The surface protective layer used in the present invention may be separately disposed on the outermost surface of the color filter substrate on the side where the color filter layer is not formed, or may be surface-protected on the surface protective layer substrate. The surface protective layer laminate of the layer is disposed on the outermost surface of the color filter substrate on the side where the color filter layer is not formed. As the surface protective layer substrate used in the present invention, the same color filter substrate as described above can be used. The thickness of the surface protective layer substrate is not particularly limited as long as it can support the surface protective layer, and specifically, it is preferably in the range of 10 to 500 /zm. Further, in the above-mentioned surface protective layer laminate, an adhesive layer containing an adhesive is usually formed on the surface of the surface protective layer substrate to be bonded to the color filter substrate. As the adhesive, the same one as the above adhesive can be used. The film thickness of the above-mentioned adhesive layer is not particularly limited as long as it can be bonded without peeling off the surface protective layer laminate, and is the same as the above-described other adhesive layer. The surface protective layer used in the present invention may, for example, be a hard coat layer, an antifouling layer, an antistatic layer or an antibacterial layer. Among them, a hard coat layer and an antifouling layer are preferable. Hereinafter, the hard coat layer and the antifouling layer will be described. (1) Hard coat layer The hard coat layer used in the present invention has a function as a function of imparting abrasion resistance to the color paper member of the present invention for color paper 100123476 22 201211592. In the present invention, a known hard coat layer can be used. Further, the term "hard coating layer" generally means a hardness of "H" or more in the pencil hardness test prescribed in JIS 5600-5-4 (1999). Among them, the hardness of the surface of the hard coat layer is preferably "3H" or more. As a material for forming such a hard coat layer, for example, an ionizing radiation curable resin can be used. The ionizing radiation-curable resin is preferably a functional group having a propyl gallate type. Specific examples thereof include a polyester resin having a relatively low molecular weight, a polyether resin, an acrylic resin, an epoxy resin, a urethane resin, an alkyd resin, a acetal resin, a polybutadiene resin, and a polythiol. Polyester resin, polyol, enamel resin, and the like. Further, a di(meth)acrylate such as ethylene glycol di(indenyl) acrylate or pentaerythritol di(methyl) acrylate monostearate; trishydroxypropyl propane tris(曱) may also be mentioned. Tris(meth)acrylate such as acrylate, pentaerythritol tris(fluorenyl) acrylate, pentaerythritol tetrakis(mercapto)acrylic acid vinegar derivative or dipentaerythritol penta(indenyl) acrylate A monomer such as a polyfunctional compound such as acrylic acid ester or an oligomer such as epoxy acrylate or urethane acrylate. The hard coat layer may contain organic fine particles or inorganic fine particles in order to improve abrasion resistance and the like. Among these, inorganic fine particles such as ruthenium are preferred because of their high hardness. Further, since the inorganic fine particles having a reactive functional group capable of forming a crosslink bond with the ionizing radiation-curable resin can further increase the film strength, it is more preferable that the film thickness of the hard coat layer is preferably 0.1123476 23 201211592. Within the range of zm~30, it is more preferably in the range of 5 //m~15 //m. The method for forming the hard coat layer is not particularly limited, and examples thereof include a coating method using a coating liquid for a hard coat layer or a transfer method for transferring a hard coat layer. (2) Antifouling layer The antifouling layer used in the present invention is a layer which can be easily removed to prevent dust or contamination from adhering, or even if dust adheres thereto. In the present invention, a known antifouling layer can be used. The antifouling layer can be formed by coating an antifouling agent extremely thin and drying it. Examples of the antifouling agent include a surfactant such as a fluorine-based surfactant, a coating material containing a fluorine-based resin, a release agent such as polycrystalline sulfonium oil, or a wax. In the present invention, the antifouling layer may be separately provided from the hard coat layer, but the antifouling layer may be formed by adding the above antifouling agent to the hard coat layer. Among them, since the cost can be reduced, it is preferable to form an antifouling layer by adding an antifouling agent to the hard coat layer. The film thickness of the antifouling layer is preferably in the range of 1 nm to 30 nm. The reason for this is that if the film thickness of the antifouling layer exceeds the above range, there is a possibility of optical influence. 5. Layer Configuration of Color Filter Member for Electronic Paper In the present invention, the color filter layer is on the side where the display portion of the electronic paper is disposed, and the optical function layer or the surface protective layer is on the side of the outermost surface of the electronic paper. Therefore, when the color filter member for electronic paper of the present invention is used for electronic paper, since the color filter layer is close to the display portion of the electronic paper, 100123476 24 201211592 can be made into an electronic paper having excellent characteristics. . The layer configuration of the color filter member for electronic paper according to the present invention can be classified into two types including an optical functional layer and a surface protective layer. u As a specific layer structure including the optical functional layer, as shown in the figure, 'there may be the order of the optical functional layer 3, the color light-emitting sheet substrate i, and the color filter layer 2' As illustrated in Fig. 3, the order of the optical functional layer 3, the optical functional layer substrate 3, the adhesive layer 5, the color filter substrate 丨, and the color calender layer 2 is as follows. Further, Fig. 3 is a schematic cross-sectional view showing another example of the color light-receiving sheet member for electronic paper according to the present invention, and the reference numerals not shown in Fig. 3 are the same as those in Fig. 1, and therefore the description herein is omitted. As a specific layer structure including a surface protective layer, as shown in FIG. 2, 'the order of the surface protective layer 4, the color of the substrate 丨, and the pure filter layer 2' may also be as gj 4 As an example, the order of the surface protective layer*, the surface protective layer substrate 4, the adhesive layer 5, and the color light-emitting sheet substrate color filter 2 is further shown in FIG. 4 for the electronic paper of the present invention. A schematic cross-sectional view of another example of a color fluorescent reticle member, which is not described in FIG. 4, may be the same as that of FIG. 1, and thus the description herein will be omitted. Further, in the configuration of each layer, it is possible to form a layer in which the adhesive layer is provided on the side of the optical sheet on which the display portion is on the side of the display portion, that is, the light-transmissive color filter is disposed on the side of the optical sheet substrate. 6 OTHER STRUCTURE 100123476 25 201211592 The color ray-receiving sheet member for electronic paper of the present invention is only a small spoon, a color filter substrate, the above-mentioned color filter layer, and the above optical functional layer or: surface protective layer There is no particular limitation, and it is possible to add 1 θ. Hereinafter, such a configuration will be specifically described. (1) Touch panel layer In the invention, the touch panel layer may be disposed between the optical function layer or the surface protective layer of the color filter substrate. Since the touch panel layer is included, when the electronic paper (four) color film member of the present invention is used in the case of good paper t, electronic paper having high convenience in inputting information by direct contact with the screen can be obtained. The touch panel layer used in the present invention generally comprises an adhesive layer. The adhesive layer can be formed on the touch panel layer and can be formed on both sides. As the adhesive material, the same material as the above-mentioned conductive material can be used. The bonding layer is not particularly limited as long as it is not peeled off, and is the same as the other adhesive layer described above. As the touch panel layer used in the present invention, a resistive film: valley can be used. Mode, first-learning method, electromagnetic wire method, ultrasonic method, etc. The resistive film m-face shape retains the gap and is constructed oppositely. If (2) the finger or material _ electricity =: deformation 'electrode contact. By applying _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The capacitive touch panel uses a method in which a capacitor is changed by a contact between a conductor such as a finger and a panel to detect an input point. Although there are a plurality of methods, a projection type is used. The system is formed by electroforming the electrodes in a matrix shape and (4) by the capacitance of each electrode (4) (10) detecting the input. The composition of the touch panel layer of the electric type, the example table 2003-511799 The description of the eight-button wild mountain is the same as that described in the 91 report. Therefore, the color light-receiving sheet member for the electronic paper that is omitted here includes the layer of the touch panel layer and the color layer member, and includes the optical function. Material H ' as shown in Figure 5 'becomes optical functional layer 3, optical function 22, layer 5, touch panel layer 6, adhesive layer 5, color slab substrate 1, private color filter, light moon state In the sample, as shown in Fig. 6, the order of the silk-faced protective layer 4 including the surface protective layer, the adhesive layer of the surface of the hearing layer, and the color filter layer 2 of the touch panel layer are obtained. The adhesive layer 5, the color light-emitting sheet substrate is the side of the outermost surface of the electronic paper, and is shown in FIG. 5 and FIG. 6, and the upper side is formed by the two layers of the display side of the electronic paper. It can also be used as an adhesive on the side of the unconfigured color enamel substrate on which the electronic paper is disposed. Fig. 6 is a schematic cross-sectional view showing an example of the electronic paper of the present invention. The symbols not shown in Fig. 5 and Fig. 6 100123476 27 201211592 are the same as those in Fig. 1, and therefore are omitted. (2) Transparent Electrode Layer In the present invention, the transparent electrode layer may be disposed on the side of the electronic paper on which the display portion is disposed with respect to the color filter substrate. The material of the electrode layer is not particularly limited as long as it is a conductive material capable of forming a transparent electrode. For example, indium tin oxide (ITO), indium zinc oxide (IZO, Indium Zinc Oxide), tin oxide, zinc oxide, or oxidation can be used. Conductive oxides such as indium and AZO (Aluminum Doped Zinc Oxide), metals such as Au and Ni, conductive polymers such as polyaniline, polyacetylene, polyalkylene thiophene derivatives, and polycrystalline decane derivatives. ' Among them, ITO can be preferably used. The thickness of the transparent electrode layer used in the present invention is not particularly limited as long as it functions as a transparent electrode layer, but is preferably in the range of 15 nm to 200 nm. The reason for this is that when the thickness of the transparent electrode layer is less than the above range, it is difficult to form the transparent electrode layer with a uniform thickness, and when the thickness of the transparent electrode layer exceeds the above range, the transparent electrode layer is used for film formation. The time and materials are increased, so the manufacturing cost becomes high.

The reason for this is that the display characteristics of the electronic paper using the color filter member for electronic paper of the present invention using 100123476 29 201211592 can be made good by bringing the transparent electrode layer close to the display portion. Further, when the transparent electrode layer laminate is disposed on the outermost surface of the electronic paper on the side where the display portion is disposed, the transparent electrode layer may be the outermost surface, and the transparent electrode layer substrate may be the outermost surface. Further, in the color filter member for electronic paper of the present invention, the transparent electrode layer is disposed on the outermost surface of the side of the electronic paper on which the display portion is disposed, and the color filter layer is disposed on the transparent electrode layer and includes only In the case where the color filter substrate is configured as a layer of a substrate, the transparent electrode layer and the color filter layer may be disposed in opposite directions.

This is because the mode has entered the practical stage and is of a particle-moving type, so that electronic paper having less viewing angle dependency and excellent responsiveness can be obtained. The electrophoresis method is an electrophoresis phenomenon in which charged particles dispersed in a solvent are moved between electrodes by an electric field. Examples of the electrophoresis method include a microcapsule method, a 100123476 30 201211592 microcup method, and the like.

Hereinafter, the use of the color light-receiving sheet member for electronic paper of the present invention for the microcapsule side = the electron medium layer of the electron (four) is described by Yi Yixing. Examples of such a display medium layer include those in which microcapsules containing white particles, black gods, and transparent partitions are dispersed by a binder resin. As the transparent dispersion medium, for example, an alcohol solvent, various vinegars, hydrazine/hydrogenated hydrogen, alicyclic hydrocarbon 1 (tetra) hydrocarbon, a functionalized sedative wind, (d) salt or other various Lai may be used alone, or Used in these mixtures to prepare surfactants and the like. As the white particles, for example, titanium dioxide, zinc white, trioxide, etc. = color (tetra) can be used as the black particles, and for example, nigrosine black, carbon black, or titanium black pigment can be used. 100123476 31 201211592 Further, if necessary, an electrolyte, a surfactant, a metal soap, a resin, a rubber, an oil, a varnish, a compound, a charge control agent containing a particle, a titanium coupling agent, and an aluminum coupling agent may be added to the pigments. Dispersing agents such as lanthanide coupling agents, lubricants, stabilizers, and the like. As a material for forming the wall film of the microcapsule, for example, a compound such as a composite film of Arabian rubber or gelatin, a urethane resin, a urea resin, or a urea resin can be used. As the binder resin, it is possible to use a film having a good affinity with respect to the wall film of the microcapsule, and having excellent adhesion to the transparent electrode layer and having insulation properties, and examples thereof include polyethylene, chlorinated polyethylene, and ethylene. A vinyl acetate copolymer, a polycrystalline oxirane resin, or the like.

As the display medium layer substrate used in the present invention, the same color filter substrate as described above can be used. The thickness of the display medium layer substrate is not particularly limited as long as it can support the display medium layer, but is preferably in the range of 10 // m to 500 / i m . 100123476 32 201211592 Further, the above-mentioned display medium layer laminate is usually formed by bonding a dot layer containing an adhesive to the substrate side of the display medium layer. As the adhesive material, the same as the above-mentioned adhesive material can be used. The film of the adhesive layer is not particularly limited as long as it can be bonded so that the display medium layer laminate does not peel off, and is the same as the above-mentioned other adhesive layer.
