Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical laminate disposed on a surface of a display such as a liquid crystal display (LCD) or a plasma display (PDP), and a method of fabricating the same, and a related art A polarizing plate of a laminate and a display device including the optical laminate or the polarizing plate. [Prior Art] The image display surface in an image display device such as a liquid crystal display, a CRT (Braun tube) display, a projection display, a plasma display, or an electroluminescence display is required to impart scratch resistance to prevent handling in operation It was damaged. To this end, an optical laminate is disposed on the surface of the above display. The optical layered body has a structure in which an optical layer is laminated on a light-transmitting substrate such as polyethylene terephthalate (hereinafter referred to as PET) or triacetyl cellulose (hereinafter referred to as TAC). Functional layer. The optical functional layer has desirable properties. For example, an optical wide-layer system having an optically functional layer and a hard coat can be used as a hard coat film having a hard coat layer. Further, the optical layered body in which the fine uneven structure is formed on the surface of the optical function layer can be used not only as a hard coat film but also as an antiglare film having an antiglare layer. Further, in the case of the optical functional layer, the light diffusion layer and the low refractive index layer are also used. The development of an optical layered body having a desired function by using an optical functional layer such as a hard coat layer or an antiglare layer in a single layer or a combination of a plurality of layers is progressing. 3 322498 201128239 In the case where an anti-glare film is used on the outermost surface of the display, when it is used in a bright room, there is a problem that the black display image is whitened and the contrast is lowered due to light diffusion. Therefore, the industry is seeking an anti-glare film (high contrast AG) capable of achieving high contrast even if the anti-glare property is lowered. That is, since the anti-glare property and the contrast are opposite properties, it is difficult to satisfy the property requirements of the two. In addition, the development of an anti-glare film capable of combining anti-glare properties and contrast is underway (for example, refer to the patent document 〇. The anti-glare film described in the patent document is produced by volatilization of a solvent. a film formed by curing a resin contained in a coating layer after forming a Benard cell structure on the surface of the coating layer by convection, formed by the method, and an anti-glare layer constituting the anti-glare film. The film thickness is set to be equal to or less than the average particle diameter of the fine particles contained in the anti-glare layer and not more than three times the average particle diameter of the fine particles. [Patent Document 1] Japanese Patent No. 4238938 (Problems to be Solved by the Invention) However, the anti-glare film described in Patent Document i can have both anti-glare properties and contrast to some extent, but the anti-glare property and contrast are insufficient. One of the reasons' In the case where the anti-glare film described in Patent Document i is concentrated on the surface of the anti-glare layer, the film thickness of the anti-glare layer is on the average particle (four) of the anti-glare layer. Flattening of the above particles In the range of three times or less the particle diameter, it is difficult to carry out the aggregation of the fine particles. If the aggregation of the fine particles is difficult, the uneven structure on the surface of the anti-glare layer is small, and the anti-glare property is insufficient. Since the film thickness of the glare layer is large and the average particle diameter of the fine particles is large, the average inclination angle of the unevenness formed on the surface is increased, and the bright room contrast is insufficient. Therefore, it is an object of the present invention to provide an anti-glare An optical laminate having a high contrast ratio and a method for producing the same, and a polarizing plate including the optical laminate, and a display device including the optical laminate or the polarizing plate. (Means for Solving the Problem) The present invention is The above-described technical problems are solved by the above-described technical problems.

(10) A method for producing an optical layered body, wherein a coating containing a sapphire component, a light-transmitting fine particle, a first solvent, and a second solvent is applied onto a light-transmitting substrate to form a coating layer. When the first solvent and the second solvent contained in the front layer are volatilized, convection occurs in the coating layer to form a domain structure 'and then' the resin component contained in the coating material is solidified to form a silk work (4). The Wei layer_thickness D and the average particle diameter of the light-transmitting fine particles contained in the optical functional layer satisfy the relationship of 3xr &lt; Dgl〇xr. According to the present invention, it is possible to provide an optical layered body which can achieve both anti-glare property and high contrast, and a method for producing the same, and a polarizing plate including the optical layered body, and the optical layered body or the polarized light The display device of the board. [Embodiment] 322498 6 201128239 The optical layered body of the present embodiment has a configuration in which an optical functional layer is provided on a light-transmitting substrate, wherein the optical functional layer has a flank structure. Fig. 1 is a view schematically showing a transition structure in an optical functional layer. (a) is a plan view showing a surface structure of an optical layered body (optical functional layer), and (b) is a side cross-sectional view showing a side cross-sectional structure of the optical layered body. Further, 'the first figure is a conceptual diagram' in which the actual scale is sometimes different. Fig. 1(a) is an enlarged plan view showing an optical functional layer constituting the present invention. In the optical functional layer constituting the present invention, a plurality of domain structures 21 exist, and a plurality of _ structures exist adjacent to each other. In addition, non-domain structures 22 are present in the gaps of adjacent tie structures. The domain structure 21 is a polymer of the light-transmitting fine particles. The non-domain structure 22 is a resin component or a light-transmitting fine particle which does not aggregate and exists independently. Fig. 1(b) is a cross-sectional view taken along line A-a of Fig. 1(a). The optical functional layer 20 is formed on the light-transmitting substrate 1A. The upper portion (the surface side of the optical functional layer 20) where the domain structure 21 exists mainly forms a convex structure, and the upper portion where the non-domain structure 22 exists forms a concave structure. That is, the surface unevenness of the optical functional layer is formed by the domain structure and the non-domain structure. Further, since the domain structure 21 凝聚 the aggregate of the light-transmitting fine particles, the upper portion of the domain structure 21 is not only a convex structure but a concave-convex structure, along with the state of aggregation of the light-transmitting fine particles. The surface unevenness of the optical functional layer formed by the domain structure is smaller than the surface unevenness made by the conventional fine particles, so that the 'light diffusion of the surface becomes small' is advantageous for exhibiting high contrast performance. The domain structure is an aggregate of light-transmitting fine particles, and the number of the light-transmitting fine particles to be aggregated is preferably (10) or more and more preferably 300 or more. Optimum is 5〇〇 322498 7 201128239 or more. The greater the number of condensed light-transmitting particles, the better. By collecting a plurality of light-transmitting particles, a gentle surface unevenness structure can be formed on the optical functional layer, contributing to high contrast. The number of structures per unit area is preferably from 20 to 1,000, more preferably from 30 to 500, and most preferably from 50 to 300, in the range of 1 mm 2 . An optical layered body having an optical functional layer in which the number of domain structures is in this range is preferably used as an optical layered body for use as an antiglare property and high contrast. If it is less than 20, there is a problem in that the interval between the surface irregularities is increased to cause a glare. If it exceeds 1,000, the number of surface irregularities increases, the average inclination angle increases, the unevenness interval becomes small, and the degree of contrast decreases. The size and number of structures have the following complementary relationship, that is, if the number of the rotating structures is increased, the size of the rotating structure becomes small, and if the number of domain structures is reduced, the size of the domain structure becomes large. In order to adjust the number of domain structures, for example, a method of adjusting the film thickness of the optical functional layer can be mentioned. More specifically, if the film thickness of the optical functional layer is increased, the domain structure becomes large, and thus the number of the bonding structures is reduced. If the film thickness of the optical functional layer is reduced, the domain structure becomes small, and therefore, the number of domain structures is increased. Big. The film thickness Ι) of the optical functional layer and the average particle diameter r (μιη) of the light-transmitting fine particles are adjusted so as to satisfy the relationship of 3xr &lt; DSl〇xr, so that it is easy to have both anti-glare properties and High contrast. More preferably 3.5xrSDS9xr, more preferably 4xrSDS8xr. When the lower limit value of D is 3xr or less, the uneven shape on the surface of the optical functional layer becomes small, and the anti-glare property is insufficient. If the upper limit value of D exceeds l〇xr, the optical layered body is liable to produce a roll 8 322498 201128239. The diameter (either one of the long diameter or the short diameter) of the domain structure in which the light-transmitting fine particles are aggregated is preferably in the range of 50 μm to 1 μm. The surface unevenness formed by the flank structure in the range is easy to scatter the incident light, so that the anti-glare property is improved. The domain structure has an arbitrary shape. As the shape of the domain structure, for example, a circle, an ellipse, a 0-shape, a 7-shape, an L-shape, or a polygon in which these shapes are combined may be mentioned. The domain structures adjacent to each other independently have an arbitrary shape. The optical functional layer constituting the present invention may be laminated on one surface of the light-transmitting substrate as it is, or may be laminated on both surfaces, directly or via another layer. Further, the optical layered body may have other layers. Examples of the other layer include a light diffusion layer, an antifouling layer, a polarizing substrate, a low reflection layer, and other function imparting layers (for example, an antistatic layer, an ultraviolet/near infrared (NIR) absorption layer, and a color purity. Lifting (neon-cut) layer, electromagnetic wave shielding layer, hard coating). Further, the position of the other layer is, for example, in the case of a polarizing substrate, on the light-transmitting substrate opposite to the optical function layer; in the case of a low-reflection layer, In the case of another functional layer, the optical functional layer is the lower layer of the optical functional layer. A laminate in which a polarizing substrate, a light-transmitting substrate, and an optical functional layer are laminated can be used as a polarizing plate. Further, the polarizing substrate, the light-transmitting substrate, and the optical functional layer may be directly laminated, or may be laminated via another layer such as an adhesive layer. &lt;Method of Forming Domain Structure&gt; 9 322498 201128239 The structure of the sound can be produced by the convection action of the aggregation of the light-transmitting particles. Specifically, the drying step may be performed by applying a solution (coating) containing a resin component, a light-transmitting fine particle, and a solvent to a light-transmitting substrate, causing convection accompanying evaporation of the solvent; and curing: The cured coating film is cured. More specifically, in general, the solvent is applied from the coating layer by applying the coating solution to the light-transmitting group H. Although the detailed mechanism of cohesion and convection has not been clarified, it can be speculated as follows. (1) By using convection and agglomeration in combination, convection domains are first generated in the coated coating layer. s (2) Next, agglomeration occurs in each convection domain, and the structure of aggregation tends to become large as time passes, but condenses at the wall of the convection domain and stops growing. (3) As a result, a domain structure is formed along with the agglomerated structure, and the domain structure is controlled by an interval corresponding to the size and arrangement of the flow domains. Regarding the surface unevenness, the portion where the surface unevenness is formed forms a domain structure. With the surface unevenness of the domain structure of the present invention, the average tilt angle is smaller than that of the surface irregularities made of the conventional fine particles, which contributes to a small light diffusion of the surface and a high contrast. The following 'environmentally usable materials constituting the layers of the present invention are clarified.乂§儿&lt;translucent substrate&gt; The light-transmissive substrate of the best embodiment is as long as it has a high light transmittance. 322498 10 201128239 has no special system, and can be used for quartz surface, glass or the like. Appropriately ❹ PET, TACH glycolic acid (pen), polymethyl methacrylate (PMMA), polycarbonate (pc), polyimine (PI), polyethylene (PE), polypropylene (pp ), polyvinyl alcohol (pvA), polystyrene (PVC), cyclic olefin copolymer (coc), norbornene resin, polyfluorite (p〇lyEtherSulf〇ne; pEs), celluloid Various resin films such as (cellophane) and aromatic polyamine. Further, in the case of a PDP or an LCD, it is more preferred to use one selected from the group consisting of a pET film, a TAC film, and a norbornene-containing resin film. The higher the transparency of these light-transmitting substrates, the better, and the total light transmittance (JIS K7105) is preferably 80 Å/〇 or more, more preferably 9 Å/〇 or more. In addition, it is preferable that the thickness of the light-transmitting substrate is thinner from the viewpoint of weight reduction, but it is preferable to use a substrate having a range of Ιμηη to 700 μm in consideration of productivity and workability. A matrix of 25 μm to 250 μm was used. By applying alkali treatment, corona treatment, plasma treatment, sputtering treatment, etc. to the surface of the light-transmitting substrate, a primer such as a surfactant or a saneane coupling (Siiane C0Upiing) is applied. Primer coating, such as dry coating, such as Si vapor deposition, can improve the adhesion between the light-transmitting substrate and the optical functional layer, and improve the physical strength and chemical resistance of the optical functional layer. Further, in the case where another layer is provided between the light-transmitting substrate and the optical functional layer, the adhesion of the interface of each layer can be improved by the same method as described above, and the physical strength and chemical resistance of the optical functional layer can be improved. . 11 322498 201128239 &lt;Optical functional layer&gt; The photo-functional layer can be coated with a resin material, a light-transmitting fine particle, and a solvent onto a light-transmitting wire to make the resin component © Hualai (four). The optical work jersey can also contain other optional components. The thickness of the functional layer is greater than that of the (4) 2. illusion 5, the range of μ ', 3. 〇gm to 1 〇〇 μιη 'best is * 〇 (four) to 9 . In the case where the optical functional layer is thinner than 2 _, the curing failure occurs due to the inhibition of the ultraviolet ray, and the resistance of the optical functional layer is likely to be deteriorated. In the case where the optical functional layer is larger than 15 〇 # #, light: force month 1 is curled by curing shrinkage, and microcracking occurs, and the φ property of the light-transmitting soil is lowered, and the light transmittance is lowered. Further, as the film thickness increases, the amount of the coating material to be increased by φ, which is also the cause of the increase in cost. 0 The optical functional layer can be used as a square layer by forming a surface uneven structure. Further, a laminated body having an antiglare layer on a light-transmitting substrate can be used as an anti-glare film. (Resin component) The resin component of the optical functional layer can be made to be particularly limited as long as it is a shape after curing and has sufficient strength and transparency. In the above-mentioned resin component, a thermosetting resin, a human Ut, a plastic resin, an ionizing radiation curable resin, a two-liquid mixture, etc. may be mentioned, and among them, an ionizing radiation-curable resin is suitable. tooth! 1 Curing treatment by electricity, radiation and ultraviolet radiation can be effectively cured by simple processing 12 322498 201128239. In the case of the ionizing radiation-curable resin, a radical polymerizable property such as an acrylonitrile group, a fluorenyl fluorenyl group, an acryloxy group, or a methacryloxy group can be used singly or in a suitably mixed composition.

These may be used singly or in combination. In the ionizing radiation curable resin, the number of functional groups is three or more, and the curing rate can be increased to increase the hardness of the cured product. Further, by using a polyfunctional amine ester acrylate, hardness and flexibility of the cured product can be imparted. Etc. 13 322498 201128239 as ionization As the radiation-curable resin, ionizing radiation-curable fluorinated acrylate can be used. Since the ionizing radiation-curable fluorinated acrylate is ionizing radiation-curable type compared with other fluorinated acrylates, cross-linking occurs between molecules. It is excellent in chemical resistance and exhibits sufficient antifouling properties after saponification treatment. Further, by increasing the amount of ionizing radiation-curable fluorinated acryl vinegar, the size of the _ structure can be increased, and each unit can be reduced. The ratio of the domain structure of the area is not particularly limited, and the ratio of the ionizing radiation-curable fluorinated acrylate contained in the optical functional layer is 100 parts by mass of the total mass of the solid component in the resin composition constituting the optical functional layer. 0.05 to 50% by mass is suitable, and 0.2 to 20% by mass is more suitable. If the amount of the ionizing radiation-curable fluorinated acrylate is less than 0.05% by mass, the water repellency and smoothness are lowered, and scratch resistance, Antifouling property and chemical resistance are deteriorated. If the amount of ionizing radiation-curable fluorinated acrylate is more than 50% by mass, film formation Here, the solid content in the optical functional layer such as the ionizing radiation-curable resin and the light-transmitting fine particles is collectively referred to as a “resin composition.” Further, the ionizing radiation-curable fluorinated acrylate may be optionally contained.

The leveling agent has a function of uniformizing the tension on the surface of the coating film and repairing defects before forming the coating, and a material having a lower interfacial tension and surface tension than the ionizing radiation-curable resin can be used. The amount of the resin component such as the ionizing radiation-curable resin is 50% by mass or more, preferably 60% by mass or more based on the total mass of the solid component in the resin composition constituting the optical functional layer. The upper limit is not limited, for example, '99.9% by mass. If it is less than 5% by mass, there are problems such as insufficient hardness in the case of 322498 20 201128239. (Translucent fine particles) For the light-transmitting fine particles, an acrylic resin, a polystyrene resin, a styrene-acrync copolymer, a polyethylene resin, or the like can be used. Organic light-transmitting resin particles formed of an epoxy resin, a silicone resin, a polyvinylidene fluoride resin, a polyvinyl fluoride resin, or the like, cerium oxide, aluminum oxide, titanium oxide, cerium oxide, oxidation Inorganic light-transmitting fine particles such as calcium, tin oxide, indium oxide, and cerium oxide. The light-transmitting fine particles preferably have a refractive index of from 14 Å to 1.75. When the refractive index is less than or greater than i 75, the difference in refractive index from the light-transmitting substrate or the resin matrix is too large, and the total light transmittance is lowered. Further, the difference in refractive index between the light-transmitting fine particles and the resin component is preferably 〇2 or less. The average particle diameter of the light-transmitting fine particles is preferably in the range of 〇 5 μm to 5 μm, more preferably Ι.Ομηη to 3 μmη. When the particle diameter is less than 〇·_, the anti-glare property is lowered. Further, when it is larger than 5 μΐ, a glare feeling is generated, and the surface unevenness is excessively generated, so that the surface appears white and thus is not preferable. In addition, the ratio of the light-transmitting fine particles contained in the optical functional layer is not particularly limited, and when the ratio is from 01 to 2% by mass based on 100 parts by mass of the resin composition, the antiglare function, glare light, etc. are satisfied. It is suitable in terms of characteristics, and it is easy to control the fine uneven shape and the haze value of the surface of the optical functional layer. Here, ''refractive index'' means a measured value according to JIS K_7142. In addition, "average control" refers to the average of the straightness of i•(9) particles measured by an electron microscope. (Solvent) 322498 21 201128239 In the case of a solvent, a solvent capable of dissolving the resin component contained in the resin composition and dispersing the light-transmitting fine particles is used. In particular, it is preferable that the solvent (solvent) for forming the surface unevenness for forming the domain structure contains the first solvent and the second solvent. By adding the first solvent and the second solvent, it is possible to form a surface uneven shape formed according to the domain structure on the surface of the optical functional layer by agglomeration and convection. The first solvent means a solvent capable of dispersing the light-transmitting fine particles well. The first solvent that can be used differs depending on the type of the light-transmitting fine particles. For example, when PMMA fine particles are used as the light-transmitting fine particles, an aromatic solvent such as toluene or a mercapto group can be used as the first solvent. A ketone solvent such as ethyl ketone (MEK) or mercaptoisobutyl ketone (MIBK). These first solvents may be used singly or in combination of two or more. The second solvent means a solvent which can appropriately agglomerate the light-transmitting fine particles. The first solvent which can be used differs depending on the type of the light-transmitting fine particles. For example, when PMMA fine particles are used as the light-transmitting fine particles, water, decyl alcohol, ethanol or the like can be used as the second solvent. These second solvents may be used singly or in combination of two or more. Here, it is preferred to use a resin component, a light-transmitting fine particle, a first solvent, and a second solvent. After the mixed coating is applied onto the light-transmitting substrate to form a coating layer, when the first and first solvents contained in the coating layer are volatilized, convection tends to occur in the coating layer. A domain structure is formed on the surface of the coating layer by the convection. After the formation of the above domain structure, the resin can be formed in the optical functional layer by curing the resin contained in the above coating material. 22 322498 201128239.

Specific examples of the agent include various cationic compounds such as a "quaternary ammonium salt" or a (tetra) salt tertiary amino group, and the like: a salt group, a Wei (tetra) group, a Wei (tetra) group, a phosphonic acid group, and the like. An anionic compound derived from ^ ^; an amphoteric compound such as an amino acid or an amine sulfuric acid (tetra); a nonionic compound such as an amino alcohol, a glycerin or a polyethylene glycol; a sintered oxide of tin and titanium Examples of the organometallic compounds such as the organometallic compounds and the gold complexes such as the acetoacetate salts thereof include compounds which polymerize the above-exemplified compounds, and have tertiary amine groups and quaternary ammonium salts. A monomer or oligomer which can be polymerized by ionizing radiation, or a polymerizable compound such as an organometallic compound having a functional group such as a coupling agent can also be used as an antistatic agent. In addition, it can be cited Specific examples of the conductive fine particles include fine particles formed of a metal oxide. Examples of such metal oxides include ZnO, Ce〇2, Sb2〇2, and Sn〇2. Often referred to as ITO indium tin oxide, Iri2〇3, A12〇3, antimony-doped tin oxide (abbreviated as germanium), doped aluminum oxide (abbreviated as AZO), etc. The above particles 322498 23 201128239 means The so-called submicron-sized particles of 1 μm or less are preferably fine particles having an average particle diameter of 0.1 nm to ί. ίμιη. Further, other specific examples of the antistatic agent (conductive agent) may be used as the conductive wire. In the case of (4), there is no special system: for example, polyacetylene, polyacene, p〇lyazuiene, or aromatic conjugated system derived from an aliphatic conjugated system Poly(phenylene), heterocyclic conjugated polyfluorene, polythiophene, polyisothiazide, polyaniline containing hetero atom conjugated system, polythiophene acetylene, mixed conjugated poly 3 (stupid ethylene) a conjugated system having a plurality of covalently consuming bonds in a knives, that is, a multi-chain co-roller system, and a conductive polymer thereof And a derivative obtained by copolymerizing or block-copolymerizing these conjugated polymer chains to a saturated polymer to obtain a high:; that is, at least one selected from the group consisting of conductive composites. In order to use an organic antistatic agent such as polythiophene, polyaniline or polypyrrole, it is possible to exhibit excellent antistatic performance by using the above organic antistatic agent, and at the same time, increase the total light transmittance of the optical laminate and reduce it. In addition, an anion such as an organic acid or a ferric chloride may be added as a pusher for the purpose of improving conductivity and improving antistatic performance. According to the effect of the addition of a dopant, a polythiophene reader ( For the electrons, you have a high-quality, anti-static and high-sounding sentence. Especially in the case of the above-mentioned polyporphin, it is also suitable for L, and Zhoutian uses oligothiophene. The above derivative is not particularly limited, and examples thereof include a mercapto substituted product of polydiacetylene and the like. For example, in the present invention, a polarizing substrate may be laminated on the light transmissive body which is opposite to the optical function 暮髀U. A polarizing plate can be produced by laminating an optical functional wind g Λ light transmissive substrate and a 322498 24 201128239 polarizing substrate. These layers may be laminated directly to each other or may be laminated via another layer such as an adhesive layer. Here, as the polarizing substrate, a light-absorbing type polarizing film that absorbs other light by penetrating only a specific polarized light or a reflective polarizing film that reflects only the specific polarized light and reflects other light can be used. In the case of the light-absorbing polarizing enthalpy, a film obtained by stretching a polyvinyl alcohol or a polyvinylene may be used, and for example, a polyethylene having adsorption of enamel or a dye as a dichroic element may be mentioned. A polyvinyl alcohol (PVA) film obtained by uniaxially stretching an alcohol. The light-reflective type of polarizing film is, for example, "dbeF" manufactured by 3M Company, and is composed of two kinds of polyester resins (PEN and PEN copolymerized) having different refractive indices in the stretching direction during stretching.
