[Embodiment] Hereinafter, the present invention (first to third inventions) will be described. Further, the descriptions in the respective items are all the first to third inventors when there is no special note. In the case of special notes, it is marked with "(* invention)" at the beginning of each item. The optical layered body of the present invention is characterized in that an optical functional layer is laminated on a light-transmitting substrate, and at least one surface of the optical functional layer is formed with an uneven shape so as to be distributed at a predetermined inclination angle. The uneven shape may be formed on a single side of the optical functional layer or on both sides. The uneven shape is preferably formed on the opposite side to the light-transmitting substrate (hereinafter, simply referred to as "surface" or "surface side"). 12 323082 201202763 The basic structure of such an optical layered body of the present embodiment is a concavo-convex shape in which at least one surface of the optical function layer is distributed with a predetermined inclination angle. The optical functional layer constituting the present invention preferably has a random agglomerated structure. Since it has a random agglomerated structure, it is easy to form an uneven shape having a predetermined inclination angle on at least one surface of the optical functional layer. Fig. 1 is a schematic view showing the structure of an optical functional layer, (a) and (b) are plan views showing the surface structure of the optical functional layer, and (c) and (d) are views showing the side cross-sectional structure of the optical laminated body. Sectional view. (a) and (c) are optical functional layers of a conventional island structure, and (b) and (d) are optical functional layers having a random agglomerated structure. Since the optical functional layer having a random agglomerated structure is only required to have at least the first phase and the second phase, the optical functional layer may have a third phase or a fourth phase, and the number of phases constituting the optical functional layer is not limited. For example, the optical functional layer may also have a laminated structure. Specifically, another phase (for example, a third phase) is formed on the unevenness of the optical function layer 16 of Fig. 1 . The optical functional layer having a random agglomerated structure, as shown in FIGS. 1(b) and (d), has at least a first phase 1 containing a relatively large amount of resin components and a relatively small amount of the resin component (containing relatively more The second phase of the inorganic component). The second phase 2 is present in a variety of sizes and shapes. The first phase and the second phase constituting the optical functional layer are present in three-dimensional intersections. When the first phase is compared with the second phase, it contains a relatively large amount of the resin component, and when the second phase is compared with the first phase, it contains a relatively large amount of the inorganic component. Further, fine particles 3 are present in the optical functional layer 16 having a random agglomerated structure. There is almost no first phase 1 constituting the optical functional layer 16 around the fine particles 3, but the second phase 2 is present. That is, the second phase 2 is 13 323082 201202763. The bias exists in the micro-good 3 constituting the filaments 6 = the presence of the microparticles 3 around the microparticles 3, which can be obtained by using the EM scanning electron microscope), EDS (energy) Decentralized X-ray beam splitter ^ is confirmed. 〇V brother · The 帛 two-phase deflection in the present month exists around the microparticles, according to the SEM results of the optical layer (4) optical functional layer, ° first. A person who selects an arbitrary one-point particle "from the towel of each job particle exists in the first phase and the second phase in the concentric circle of 10 times the long diameter of the wire, and obtains the first ratio. Then 'calculate the average value of the second phase in the same heart circle of any 1G point. As long as it is relatively high when compared with the average value, "the second phase is biased around the particles" as long as the average When the value is relatively low compared with the age control, it is not that "the second phase is biased around the microparticles." The comparison control can be obtained from the above-mentioned findings. The comparison control is centered on a certain point of the 10th point of the phase. Corresponding to the above respective particles A concentric circle of 10 times the length of a long diameter. However, a point of 1〇 is a place where all of the concentric 11 does not contain particles. Thus, the second phase can be calculated at a certain point of 10 o'clock. The average value of the proportions in the concentric circles. In the present invention, the first phase and the second phase of the 'A-scientific function are intertwined with each other'. 7^ The second phase is biased to exist around the microparticles. In the optical function layer 15, the surface of the optical functional layer 15 is formed on the light-transmitting substrate 20 by the shape of the fine particles 30 and 31. 323082 14 201202763 That is, due to the presence of the fine particles 30 The resin 40 on the 31 is raised in accordance with the shape of the fine particles, and the portion of the resin 40 which is not present in the fine particles 30, 31 is not raised, so that the convex portion and the concave portion are alternately formed, so that the surface of the optical functional layer 15 is uneven. In the first drawings (a) and (c), even if a plurality of fine particles are present to form surface irregularities, the surface irregularities are inclined to a larger extent. Constructed optics Since the second layer of the energy layer 16 is present around the fine particles 3, the fine optical unevenness can be reduced compared with the conventional optical functional layer shown in Figs. 1(a) and (c), and the high anti-glare property can be improved. The blackness under the bright room. This is because the optical functional layer with a random cohesive structure forms a relatively flat surface on the first phase, so that the first phase enhances the blackness under the bright room and achieves high darkroom contrast. Since the convex portion is formed by mixing the fine particles in the second phase, the anti-glare effect is achieved by mixing the fine particles in the second phase, that is, the distribution can be easily formed on at least one side of the optical functional layer. The concavo-convex shape having a predetermined inclination angle. Further, if the second phase is not present around the microparticles and the microparticles are present in the first phase and the second phase, the concavities and convexities are formed in the optical functional layer (the number of concavities and convexities is increased) ), and the optical functional layer is whitened, so it is not good. At the same time, the optical functional layer containing no fine particles is difficult to control because it is difficult to control the number or height of surface irregularities, which is not preferable. The optical functional layer constituting the present invention is preferably an optical functional layer having a random agglomerated structure as a main structure, and for example, some other structures may exist (for example, an island structure). After gold vapor deposition on a random agglomerated structure, it was found from the observation of the electron microscope 15 323082 201202763 that the fine particles contained in the optical functional layer were convex portions forming surface irregularities. Further, after carbon deposition on a random agglomerated structure, the element distribution of the carbon noodle surface can be roughly confirmed by observation with an electron microscope. This is because there are a plurality of elements in the carbon-steamed surface, for example, the atomic order is expressed as white, the atomic order is small, and the black is represented by color, and the distribution of the elements can be represented by the shade of the color. Further, for an optical functional layer having a random agglomerated structure, an element existing on a surface of a coating film (optical function) or a coating film (optical functional layer) can be confirmed by mapping by EDS. The application of this EDS marrying image can be expressed in a color distribution with a large distribution of U (e.g., carbon atoms, oxygen atoms, lean atoms, etc.). By using the above-described electron microscope observation and the drawing of EDS, it is confirmed that the uneven structure of the random agglomerated structure or the distribution of specific elements is confirmed. Thereby, for example, it is possible to confirm that the convex portion of the surface is uneven, and the distribution of a specific element is large. / Use the 2nd and 4th drawings to specify. Fig. 2 and Fig. 4 are views showing the surface state of an optical functional layer (optical functional layer having a random agglomerated structure) prepared in Example 5, which will be described later, in the same field of view, wherein the optical functional layer is composed of a resin component and It is composed of inorganic components. Fig. 2 is a SEM photograph of carbon deposited on the surface of the optical functional layer. The image displayed in the reflection electron detection is the image of the reflected electron caused by the component contained on the surface of the optical functional layer. The electron is dependent on the atomic sequence. For example, the atomic order can be expressed as ",,, atom. The small order is represented by black, etc. According to the color diagram of Fig. 2, 323082 16 201202763, the elements in the optical functional layer are not uniformly present in the horizontal direction of the surface, but the content of the element having a large atomic order is relatively large. The portion and the content are relatively small. Fig. 4 is a graph showing the results of the inorganic component (Si) of the EDS on the optical function level, and the amount of the Si component contained in the shade of the color. As shown in the figure, there are also a relatively large portion and a relatively small content of the Si component. Moreover, the specific example in Fig. 4 indicates the drawing result of cerium (Si), but other inorganic component elements may also be indicated. Or the result of the mapping of the resin (organic matter) component. Although the drawing result shown in Fig. 4 differs depending on the detection conditions, it can be detected as long as the inorganic component such as cerium is 0.2% by mass. That is, in the optical functional layer composed of the two phases of the first phase and the second phase, the first phase is composed of 90% by mass or more of a resin component and an inorganic component, and the second phase is less than 99. 8 mass% of the resin component and 0.2% by mass or more of the inorganic component. The resin component contained in the first phase is preferably 95% by mass or more, and more preferably 99% by mass or more. The inorganic component to be contained is preferably 1% by mass or more, more preferably 5% by mass or more, and particularly preferably 10% by mass or more. The resin component contained in the second phase is preferably less than 99% by mass, and is not 95% by mass is preferable, and particularly preferably less than 90% by mass. The amount of the inorganic component contained in the optical functional layer is more than the first phase in the second phase. The content of the resin component is relatively large The content of the component other than the resin component is relatively small (first phase). On the other hand, the content of the resin component is relatively small (the color of the second figure is light) Part)) The content of ingredients other than the resin component becomes relatively large. 17 323082 2012027 63 (second phase). That is, the optical functional layer having a random agglomerated structure is a complementary relationship between the first phase and the second phase in which the first phase and the second phase are present, and when one component is decreased, the other components are increased. In addition, in the second and fourth figures, the content of each component in the horizontal direction of the surface of the optical functional layer is shown, but when the content of each component in the vertical direction (thickness direction) of the optical functional layer is shown, The result of the non-complementary relationship is also obtained (Fig. 3). <Method of forming a random agglomerated structure> The random agglomerated structure is a random bias which is present in the condensate of the inorganic component with the convection of the solvent It is manufactured by the phenomenon around it. ★ In detail, after applying a solution containing a resin component, an inorganic component, fine particles, and a solution (the first solvent and the second solvent) on a light-transmitting substrate, the solvent is over 1k. It is produced by volatilization to produce a convection drying step and a hardening step of drying the crucible to form an optical functional layer. More specifically, it is usually carried out by applying the solution to a light-transmitting substrate and evaporating the coating layer. However, although the detailed mechanism for the combination of cohesion and convection cannot be clarified, it is as follows. First, after coating, U) is agglomerated by convection accompanying evaporation of the solvent, and a convection zone is generated on the coating layer. In each (four) pair (4), the convergence of the birth zone, although the condensation =: with the _ and red, the growth of the condensation in the wall will stop the generation and time of the condensate, so that the inorganic components with the particles as the core 323082 18 201202763 Heart and cohesion. (3) As a result, the aggregates are kept at an appropriate size, and these are dispersed in the optical function layer to form a random agglomerated structure. According to the surface unevenness accompanying the random agglomerated structure, both the anti-glare property, the bright room contrast, and the darkroom contrast which are difficult to achieve in the conventional sea-island structure can be achieved. Hereinafter, materials which can be applied to each layer constituting the present invention will be described. <Translucent Substrate> The translucent substrate according to the present embodiment is not particularly limited as long as it has translucency, and glass such as quartz glass or soda glass may be used, and PET, TAC, or PET may be used.

Further, when another layer is provided between the light-transmitting substrate and the optical functional layer, the physical strength and chemical resistance of the optical functional layer can be improved by the same square soil method as described above to improve the adhesion of the interface of the respective layers.

Among the fluorinated acrylates, a fluorinated alkyl urethane acrylate having a urethane bond is preferred because of the abrasion resistance and stretch and flexibility of the cured product. Further, among the fluorinated acrylates, polyfunctional fluorinated acrylates are preferred. Further, the polyfunctional fluorinated acrylate as used herein means two or more (preferably three or more', more preferably four or more) (fluorenyl) acryloyloxy groups. The ionizing radiation-curable resin can be directly cured by irradiation with an electron beam. However, when it is cured by irradiation with ultraviolet rays, it is necessary to add a photopolymerization initiator. Further, as the radiation to be used, any of ultraviolet rays, 323082 26 201202763 visible light rays, infrared rays, and electron beams can be used. In addition, these radiations may be polarized or unpolarized.

A cationic polymerization initiator such as a salt, an aromatic onium salt or a metal aryl compound can be used, and these polymerization initiators can be used singly or in combination as appropriate. Further, the ionizing radiation curable resin may contain an additive such as a leveling agent or an antistatic agent. The leveling agent can improve defects before the formation of the coating film to uniformize the tension on the surface of the coating film. Examples of the leveling agent include stone, _(silic〇ne)-based leveling agent, gas-based leveling agent, and acrylic leveling agent. The leveling agent may be used singly or in combination of two or more types. In the case where the uneven structure is formed on the optical functional layer, the leveling agent is preferably a stone grading agent or a leveling agent.

"Polyf low-77" (the above product name) manufactured by the company. When the content of the leveling agent of the optical functional layer is too small, the leveling effect of the coating film is not easily obtained. When the leveling agent is excessively placed, it is difficult to form an agglomerate of the inorganic component. From the above viewpoint, when the total content (excluding the organic solvent) of the optical functional layer is 100% by mass, the content of the leveling agent in the optical functional layer is preferably in the range of 0.05 to 3% by mass, and is 0. A range of 1 to 2% by mass is preferable, and a range of 0.2 to 1% by mass is particularly preferable. The blending amount of the resin component such as the ionizing radiation-curable resin is preferably 50% by mass or more, and preferably 60% by mass or more, based on the total mass of the solid component in the resin composition constituting the optical functional layer. 8质量百分比。 The upper limit is not particularly limited, for example, 99.8 mass%. If it is less than 5% by mass, there will be a problem that it is difficult to obtain sufficient hardness. In addition, the solid component of the resin component such as the ionizing radiation-curable resin contains all the solid components other than the inorganic component and the fine particles described later, and is not only a solid component of a resin component such as an ionizing radiation-curable resin, but may contain other optional components. . (Inorganic component) The inorganic component used in the present invention may be any one of the optical functional layer 3 which is formed by agglomeration at the time of film formation to form a second phase and a random agglomerated structure.

The above inorganic nanoparticles may be used singly or in combination of plural kinds. Further, the particles are different from the inorganic components (inorganic nanoparticles) and can be distinguished by particle size. Among these inorganic nanoparticles, layered organic clay is preferred from the viewpoint of forming a stable random aggregation structure. The reason why the layered organic clay can form a stable random agglomerate structure, for example, is that the first phase and the second phase are easily formed because of the high compatibility and cohesiveness of the layered organic clay and the secret component (organic component). It is easy to form a random agglomerated structure when the structure of the transaction is complicated. In the present invention, the layered organic clay is one in which organic rust ions are introduced between the layers of the swellable clay. The layered organic clay has low dispersibility for a specific solvent, and when a layered organic clay and a solvent having a specific property are used as a coating for forming an optical functional layer, a surface having a random agglomerated structure can be formed by the selection of the solvent. Concave optical function layer. The swellable clay swellable clay may be a clay having a cation exchange energy and pouring water into the layer of the swellable clay to be swellable, and may be a natural product or a ruthenium composition (including a substitute or a derivative). .

Examples of the salt include anions (IV) such as Cr, Br_, N〇3_, 〇H_, and CH·. As the salt, it is preferred to use a quaternary ammonium salt. 2 However, the functional group of the organic phosphonium ion is not limited, but any material containing an alkyl group, a phenylhydrazine group, a polyoxypropyl group or a phenyl group is preferred because it is easy to exhibit antiglare properties. The preferred alkyl group is in the range of i to 3 Å, and examples thereof include a methyl group, an ethyl group, a propyl group, an isopropyl group, a butyl group, a pentyl group, a hexyl group, a heptyl group, an octyl group, a decyl group, and an anthracene group.

The desirable range of η in the polyoxyl propyl group [(CH2CH(CH3)〇)nH or (CH2CH2CH2〇)nH] is 4 50' and preferably 5 to 5 Å, since the addition of the molar number is more The more the dispersibility of the organic solvent is, the more the adhesive is attached to the product, so that the viscosity of the solvent is preferably 20 to 50. In addition, if the number of η 323082 31 201202763 is 5 to 20, the product is non-adhesive and has good pulverizability. In addition, the term "distribution and usability" should be such that the total number of η in the fourth-order narration is 5 to 50. Specific examples of the quaternary ammonium salt include tetraalkylammonium chloride, tetraalkylammonium bromide, polyoxypropylene·trialkylammonium halide, polyoxypropylene•trialkylammonium bromide, and (polyoxypropylene)·dialkylammonium vapor, di(polyoxypropylene)·dialkylammonium bromide, tris(polyoxypropylene)·alkyl vaporized ammonium, tris(polyoxypropylene)·alkyl bromide Ammonium and the like. Among the quaternary ammonium ions of the formula (I), a suitable Ri is a fluorenyl group or a fluorenyl group. A suitable R is an alkyl group having 1 to 12 carbon atoms, and preferably an alkyl group having a carbon number of 4 to 4. A suitable R3 is an alkyl group having 1 to 25 carbon atoms.

I R3_____________ In addition, it is preferred to use oxidized I-alloy as the inorganic nano-particles, which is preferable because the surface hardness of the optical functional layer can be improved and the scratch resistance is also improved. The inorganic nanoparticles may also be modified inorganic nanoparticles. For the modification of inorganic nanoparticles, a decane coupling agent can be used. As the decane coupling agent, for example, ethylene trimethoxy decane, 3-glycidylpropyltrimethoxy decane, p-styryl trimethoxy decane, 3-methyl propylene methoxy propyl triethyl group can be used.

The average particle diameter of the inorganic fine particles is preferably 10 nm or less, more preferably 50 nm or less, and most preferably 20 nm or less. The inorganic nanoparticles are not limited to the lower limit of the average particle diameter as long as they have cohesiveness, for example, 1 nm. When the average particle diameter of the inorganic nanoparticles exceeds 1〇〇11111, the haze value of the optical layered body tends to be high, and in addition to the phenomenon that whitening is easily observed, the contrast is also lowered. The amount of the inorganic component is preferably from G to 1 to 10% by mass, and preferably from 2 to 5% by mass, based on the total mass of the solid component in the resin composition. If the amount of the inorganic component is less than 质量% by mass, a sufficient amount of surface irregularities cannot be formed, and there is a problem that the antiglare property is insufficient. If the amount of the inorganic component exceeds 1 (), the number of surface irregularities is increased, and there is a problem that the visibility is hindered. (Solvent) A solvent which forms surface irregularities in order to obtain anti-glare property preferably contains a first solvent (may also be referred to as "first solvent") and a second solvent (also referred to as "second solvent"). In the above-mentioned tree residue of the present invention, the i-th solvent and the second agent can be used as the coating material for forming a fresh functional layer of the present invention.

Substantially no turbidity is included. In addition to no turbidity at all, it is considered that turbidity does not occur. Specifically, when the amount of the first solvent is 100 parts by mass based on the inorganic component, a solvent having a haze value of 10% or less by adding 1000 parts by mass of the first solvent mixture is added. Further, the haze value of the mixed solution obtained by mixing the first solvent is preferably 8% or less, and more preferably 6% or less. 1%。 The lower limit of the haze value of the mixture is not particularly limited, for example, 0.1%. As the first solvent, for example, a solvent having a small polarity (non-polar solvent) can be used. The second solvent is a solvent which is dispersed in a state in which turbidity occurs in the inorganic component. Specifically, when the amount of the second solvent is 100 parts by mass based on the inorganic component, a solvent having a haze value of 30% or more by adding 1000 parts by mass of the second solvent mixture is added. The mixed solution obtained by mixing the second solvent is preferably a haze value of 40% or more, and more preferably 50% or more. Further, the upper limit value of the haze value of the mixed liquid is not particularly limited, and is, for example, 99%. As the second solvent, for example, a so-called polar solvent can be used. Further, the haze value required for determining the first solvent and the second solvent is measured in accordance with JIS K7105. The first solvent and the second solvent which can be used vary depending on the type of the inorganic component. A solvent which is the first solvent and the second solvent can be used, and an alcohol such as decyl alcohol, ethanol, propanol, 2-propanol, butanol, isopropanol (IPA) or isobutanol; acetone or methyl group can be used.

These solvents may be used as the first solvent or the second solvent, or a plurality of them may be mixed as the first solvent or the second solvent. In this case, when the first solvent and the second solvent are mixed, it is preferred to form surface irregularities for obtaining anti-glare properties. When the mass ratio is used as the mixing ratio of the first solvent and the second solvent, it is preferably in the range of 10:90 to 90:10 because it is easy to form surface irregularities for obtaining anti-glare properties. When the mass ratio is used as the mixing ratio of the first solvent and the second solvent, it is preferably in the range of 15:85 to 85:15 and more preferably in the range of 20:80 to 80:20. When the first solvent is less than 10 parts by mass, there is a problem of appearance defects due to the undispersed material. When the amount of the first solvent exceeds 90 parts by mass, there is a problem that surface unevenness of sufficient antiglare property cannot be obtained. Further, the blending amount of the resin composition and the solvent (the first solvent and the first solvent are mixed) is a mass ratio, and if the resin composition is less than 30 parts by mass in the range of 70:30 to 30:70, The appearance is deteriorated due to the occurrence of dry streaks and the like, and the number of surface irregularities is increased, which has a problem of hindering the visibility. 35 323082 201202763 When the resin composition exceeds 70 parts by mass, the solubility (decomposability) of the solid component is easily hindered, and there is a problem that film formation cannot be performed. (Microparticles) The above resin composition is a fine particle containing light transmissive. After the coating material for forming an optical functional layer obtained by adding a solvent to the resin composition is applied onto the light-transmitting substrate, the optical functional layer can be formed by curing the coating material for forming the optical functional layer. The shape or the number of surface irregularities of the optical functional layer can be easily adjusted by adding translucent fine particles to the resin composition. As the light-transmitting fine particles, acrylic resin, polystyrene resin, styrene-acrylic copolymer, polyethylene resin, epoxy resin, ruthenium resin, polyvinyhdene fluoride, and polyvinyl fluoride can be used.

The refractive index of the light-transmitting resin microparticles is preferably from 1.40 to 1.75. If the refractive index is less than 1.40 or greater than L 75, the refractive index difference between the light-transmitting substrate or the resin matrix is too large, and the total thickness is lowered.

The average particle diameter of the light-transmitting fine particles is preferably in the range of 0.3 to 7.0 / zni, preferably from h 〇 to 7 ,, and more preferably from 2 〇 to 6 () / Zm. When the particle diameter is less than 0.3 μm, the anti-glare property is not preferable, and when the right particle diameter is larger than 7.0, the surface is whitened due to excessive glare and unevenness of the surface, which is not preferable. In addition, although the ratio of the light-transmitting fine particles contained in the above-mentioned resin is not particularly limited, when it is 100 parts by mass with respect to the resin group 323082 36 201202763, it is preferable that the ratio is 〇·1.

The "refractive index" herein refers to the measured value according to JIS Κ 7142. In addition, "flat-to-tenth pull-in" refers to the average of the diameters of 10 particles measured by an electron microscope. The amount of the fine particles in the total amount of the solid content in the resin composition constituting the optical functional layer is more than or equal to 1.0% by mass, and is preferably 1.0% by mass. The upper limit value is not particularly limited, and for example, if the mass I does not reach the G.1 quality section, there will be a problem that sufficient anti-glare property cannot be obtained. Antistatic Agent (Conductive Agent) The optical functional layer of the present invention may also contain an antistatic agent (conductive agent). By the addition of the conductive agent, it is possible to effectively prevent dust from adhering to the surface of the optical layered body.

The optical functional layer may be formed on a single side of the light transmissive substrate or on both sides. Further, other layers may be provided between the optical functional layer and the light-transmitting substrate opposite to the optical functional layer, and other layers may be provided on the optical functional layer. Other layers herein include, for example, a polarizing layer, a light diffusing layer, a low reflecting layer, an antifouling layer, an antistatic layer, an ultraviolet/near infrared (NIR) absorbing layer, a neon cut layer, and an electromagnetic wave.

When the thickness of the optical functional layer is thinner than 1.0/zin, the ultraviolet light is hardened due to the inhibition of oxygen, and the abrasion resistance of the optical functional layer is easily deteriorated. When the thickness of the optical functional layer is more than 12. Oem, curling occurs due to hardening shrinkage of the optical functional layer, microcracking occurs, adhesion to the light-transmitting group is lowered, and light transmittance is lowered. Moreover, as the film thickness increases, the amount of necessary paint is increased, which becomes the cause of the increase in cost 39 323082 201202763.至为为0. 0至75. 0。 The optical layer of the present invention, the image sharpness is preferably 5. 〇 to 85. 0 range (according to JIS K7105, using a value measured by a 0. 5mm optical comb filter) ' and from 20. 0 to 75. 0 Preferably. If the sharpness of the image is less than 5.00, the contrast will be deteriorated. If it exceeds 85.0, the anti-glare property will be deteriorated, so that it is not suitable as an optical laminate used as the surface of the display. (First invention) Next, the uneven shape of the optical functional layer constituting the optical layered body of the first invention will be described in detail. The uneven shape of the optical functional layer was obtained in accordance with ASME/1995 (American Society 〇f Mechanical Engineers, American Society of Mechanical Engineers). In the optical function layer having the concavo-convex shape, in the inclination angle distribution of the total length measured by measuring the concavo-convex shape, the ratio of the inclination angle distribution of 2 degrees or less is in the range of 30% or more and 95% or less. An optical laminate that combines anti-glare, blackness under bright room, darkroom contrast, and glare-proof. In the oblique angle distribution of the total length of the measurement obtained by measuring the uneven shape, the proportion of the inclination angle distribution of 0.2 or less is preferably 35% or more and 75% or less, and preferably 38% or more and 58% or less. (Second Invention) Next, the uneven shape of the optical functional layer constituting the optical layered body of the second invention will be described in detail. The uneven shape of the optical functional layer was obtained in accordance with ASME/1995 (American Society of Mechanical Engineers, American Society 40 323082 201202763 Cognac Specification). In the optical function layer having the concavo-convex shape, the estimated angle of the inclination angle distribution of 0.3 degrees or more and 1.6 degrees or less is 68% or more in the inclination angle distribution of the total length measured in the shape of the concave and convex shape. 3. Seto: Since the ratio of the above-mentioned inclination angle component is within the range of less than 1%, it is possible to obtain an optical laminate which is excellent in anti-glare property, high in blackness under a bright room, and glare-proof, and which is excellent in a dark room. In the present invention, it is necessary to form at least one of the optical functional layers with a pretilt angle distribution to form an uneven shape. Although another layer (for example, a high refractive index layer or a low reflection layer) may be provided on the uneven surface of the optical functional layer, when the other layer is laminated by coating, it is easy to be in the concave portion of the concave surface of the optical functional layer. There are other layers on the part, and it is not easy to have other layers on the convex part. Therefore, although the other layers are formed with the concavo-convex shape, an oblique angle distribution (having a shape having a large low inclination angle) which is smaller than the slope of the concavo-convex shape of the optical functional layer is formed. (Second invention) The optical layered body according to the second aspect of the invention is a ratio of an inclination angle distribution of 0.3 degrees or less to θ of 1.6 degrees or less in the inclination angle distribution of the total length measured by measuring the uneven shape of the optical functional layer. It is preferable that the ratio of the inclination angle distribution is 6〇% or more, and the ratio of the inclination angle distribution is 72% or more, and the ratio of the inclination angle distribution is More than 75% is the best. The upper limit is not particularly limited, and may be, for example, 95%. In the inclination angle distribution of the total length measured by measuring the uneven shape of the optical functional layer, the inclination angle distribution of 0.3 to 1.6 degrees or less is in a predetermined range, so that high anti-glare property can be provided. Gives a moderate degree of blackness under the bright room while preventing the reduction of glare-proof performance. If the ratio of the oblique angle distribution is less than 68%, an optical functional layer which is excellent in balance and has anti-glare properties, blackness under a bright room, and glare-proof performance cannot be obtained. (Second invention) In the optical product body of the first invention, the inclination angle distribution of the entire length measured by measuring the uneven shape of the optical functional layer is less than the ratio of the inclination angle distribution of 3·〇 or more. 1%, preferably less than 5%, and less than 0.1% is better or not, that is, 〇%. In the inclination angle distribution of the total length measured by measuring the uneven shape of the optical functional layer, the ratio of the inclination angle distribution of 3.0 degrees or more is within a predetermined range, so that the reduction of the glare-proof performance can be prevented. If the ratio of the oblique angle distribution above 3 〇 is more than 1%, the surface density of the optical functional layer is reduced, which impairs the glare-proof performance, and the surface scattering is further increased, thereby impairing the blackness under the bright room. . (Third invention) Next, the uneven shape of the optical functional layer constituting the optical layered body of the third invention will be described in detail. 9 The uneven shape of the optical functional layer was obtained in accordance with ASMEM995 (American Society of Mechanical Engineers, American Society of Mechanical Engineers). In the optical function layer having the concavo-convex shape, in the inclination angle distribution of the total length measured by measuring the concavo-convex shape, the ratio of the inclination angle distribution of 5 degrees or less is 60% or more and less than 8〇%, and 0.6 degrees is 42. 323082 201202763 The ratio of the inclination angle distribution below 1. 6 degrees is 30% or less '3. The ratio of the inclination angle component above the twist is less than 1%, so the balance can be balanced and moderately anti-glare, shell An optical laminate with excellent blackness, high glare resistance, and excellent darkroom contrast. In the third invention, at least one of the optical functional layers must have a predetermined oblique angle distribution 'formed with a concavo-convex shape. Although another layer (for example, a high refractive index layer or a low reflection layer) may be disposed on the uneven surface of the optical functional layer, it is easy to be on the uneven surface of the optical functional layer when coating other layers. There are other layers in the concave portion, and it is not easy to have other layers in the convex portion. Therefore, although the other layers are also formed with uneven shapes, an oblique angle distribution is formed which is smaller than the unevenness of the optical functional layer. Have more low inclination angles). (Third invention) In addition, the optical layered body of the present invention is a tilt angle distribution of the total length of the measurement obtained by measuring the optical functional layer = shape, and the ratio of the knives of the knives of 5 degrees to 6 degrees at the angle of hi is 7 More than 6% of the total is less than 80%. It is preferably from MUD 8 〇 / °, and more preferably 7 % or more and less than 80%. Inclination angle: = The full-length measurement obtained by the concave-convex shape of the second energy layer is maintained at a predetermined ratio of _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In the oblique angle distribution of the total length of the ridges of the optical function layer, the inclination density below G5 degree is lowered, and the damage prevention glare is ==== angle 323082 43 201202763 degree distribution ratio is 80% or more, it will prevent Reduced glare. (Third Aspect) In the optical layered body of the third aspect of the invention, the ratio of the inclination angle distribution of 0.6 to 1.6 or less in the measurement of the inclination angle distribution of the entire length of the optical functional layer is More preferably, it is 5% or more and 30% or less, and more preferably 5% or more and 25% or less, and more preferably 8% or more and 23% or less, and more preferably 10% or more and 20% or less. In the inclination angle distribution of the total length measured by measuring the uneven shape of the optical functional layer, the ratio of the inclination angle distribution of 0.6 degrees or more and 1.6 degrees or less is within a predetermined range, so that an appropriate anti-glare property can be imparted. The blackness under the bright room can prevent the reduction of the anti-glare performance. In the measurement of the inclination angle distribution of the entire measurement length measured by the uneven shape of the optical function layer, the ratio of the inclination angle distribution of 0.6 to 1.6 degrees is more than 30°/. At the time, the surface compactness of the optical functional layer is lowered to impair the glare resistance. (Third invention) The inclination angle distribution of the entire measurement length measured by measuring the uneven shape of the optical functional layer is preferably 1.7 or more and 2.9 or less, more preferably 35% or less, and 30 or less. The following is preferred, and it is preferably 25% or less, and 20% or less.

In the inclination angle distribution of the total length measured by measuring the uneven shape of the optical functional layer, the ratio of the inclination angle distribution of 3.0 degrees or more is within a predetermined range, so that the reduction of the glare-proof performance can be prevented. When the ratio of the inclination angle distribution of 3.00 degrees or more exceeds 1%, the surface sensitivity of the optical functional layer is lowered to impair the glare resistance. Furthermore, the surface scattering property is increased, and the blackness under the bright room is impaired. The distribution of the inclination angle of the uneven shape defined in the present invention is first determined by measuring the uneven shape of the optical functional layer in accordance with ASME/1995. Next, the height (Y) of the unevenness (X) of the length (X) was measured every 0.5 m/m in the total length of the measurement obtained by measuring the uneven shape, and the partial inclination (AZi) was calculated from the following formula. [Number 1] Δ Z, = {dYM - 9 X dYi+2 + 45 x dYM - 45 x dY^ + 9 x dY^ - dY^ ) /(60 x dXt) where AZi means any arbitrary measurement Local tilt of position dXi.
