Description

[Technical Field] The present invention relates to a method of producing an optical laminate and an optical laminate. [Prior Art] ▲ As a display, monitor, touch panel, etc., it is known to have a hard coat (scratch resistance) and antistatic property (to prevent dust from being attached to the liquid crystal). An optical layered body composed of functional layers such as a disorder caused by charging, an antireflection property (increased viewing property), an antiglare property, an antifouling property (preventing fingerprint adhesion), and the like. Among the above optical laminates, there is known an antiglare layer having a surface having a concavo-convex shape in order to improve the external light to the image, the reflection of the surface, or the deterioration of the visibility caused by the reflection of the exterior. I have such an anti-glare layer. When the optical layered field is placed in a shape of a high-definition type liquid crystal display device which has gradually become mainstream in recent years, image light is scattered due to the above-mentioned uneven shape. Glare of the stomach. In order to prevent the glare, it is known that the optical layered body is additionally formed with a layer having internal scattering properties to have a two-layer structure. In recent years, in order to achieve thinner filming of optical laminates, the anti-glare property of a layer structure has been sought. For example, Patent Document 1 discloses an anti-glare hard coat film which is provided with an anti-glare hard coat layer on one side of a transparent plastic film, and is characterized in that the anti-glare hard coat layer contains two kinds of resins and pigments. The surface haze of the glare coating is caused by the unevenness formed by the phase separation of the above two kinds of resins, and the internal haze is due to the refractive index of the resin of the above 2 201124278 It is produced by the internal scattering caused by thousands of different ancestors. Patent Document 2 discloses a rare anti-glare film which is composed of an anti-glare layer and a resin layer having a low refractive index. 兮~^ έ士接 a "constitutor' 3 ed anti-glare film on the surface It has concave and convex and famous mouth structure, so that the incident light is isotropically read a 蛀 ― U (10) transmitted and scattered, with a specific scattering angle, characteristic full light transmittance, haze and sharpness. In addition, 'patent document 3 φ deer + female, no one in the eye, no hard coating film, which is coated on the base film', the hard coating layer contains (eight) hardened material of active energy ray hardening material and (8) thermoplastic The resin, the component (4) forms a phase-separated structure with the component (B), and the right side + has a specific internal haze value. However, when these optical squats are used especially in the case of high-definition image panels developed in recent years, although the field imparts anti-glare or anti-glare properties, the phase-separated structure forms a convex shape and is easy to form a rule. The pattern thus has a problem of generating moiré between the grid pattern of the pixel and the display pixel, or the contrast is lowered due to whitening.

According to a first aspect of the invention, an optical layered body having at least an antiglare layer on a light transmissive substrate is characterized in that the antiglare layer has an uneven shape on a surface opposite to the light transmissive substrate. The uneven shape is composed of a concavo-convex shape (A) and a concavo-convex shape (B), and the concavo-convex shape (a) is formed by phase separation of an adhesive resin constituting the anti-glare layer, and the uneven shape (B) is It is formed of the internal particles contained in the anti-glare layer, and the uneven shape (A) constitutes a sea-island structure in which the convex portion is an island portion and the concave portion is a sea portion.

The value Rku is 4 or less.

Further, in the first and second inventions, it is preferable that the internal particles have a affinity for (4) U 5 201124278 which contributes to the formation of the concave portion of the uneven shape (4) on the surface of the antiglare layer, which is higher than the pair to contribute to prevention. Glare _ The affinity of the resin component of the concavo-convex convex portion on the surface of the mouth. In addition, the present invention is also an optical # a ^ manufacturing method of a laminated body, the scorpion laminated system on the light transmissive substrate to the small y y anti-glare layer, made of water The method of the present invention is characterized in that it has the following steps: j., on the above-mentioned light-transmitting substrate, coating an anti-glare layer containing a binder resin and an internal puller which are incompatible with each other. The step of forming a coating film to harden to form an antiglare layer. The above coating film Hereinafter, the present invention will be described in detail. The first and second inventions of the present invention are: _ _ + 6β ^ # ...

Therefore, when the #日月 t optical laminate is placed on the high-definition image panel, it is possible to prevent the occurrence of 4 panels or moiré without lowering the contrast of the image. The A ray is particularly suitable for the opposite side of the transmissive substrate in the optical layered body of the first and second aspects of the present invention, and has a concavo-convex shape (1) disk/, and has a concavo-convex shape, and the concavo-convex shape is two-dimensional. (8) constituting the concave-convex shape (8) which receives the internal particle-shaped uneven shape contained in the anti-glare layer by the phase separation (8) of the adhesive resin which is formed into the anti-glare layer, and the anti-glare layer The surface irregularities are calculated as right 摅 + — & small lines are mainly determined by pigments, filled or inorganic particles, or by resin. The trowel formed but has a concave-convex shape formed by particles on the surface of the anti-glare layer. 201124278 Optical laminate Μ 'The concave-convex shape is large and the kurtosis is large, although the internal scattering property is appropriately given, but the contrast of the bright room is lowered. The so-called black feeling is not enough. Further, the optical layered body having the uneven shape formed by the phase separation of the binder resin on the surface of the antiglare layer has a problem that the uneven shape is regularly present, and the interference with the lattice pattern of the display pixel is easily generated. The cloud pattern caused. In the optical layered body according to the first aspect of the invention, the antiglare layer is characterized in that it has a concavo-convex shape (Α) formed by phase separation of the binder resin and also has formed by the added internal particles. The surface uneven shape (Β), and the uneven shape (Α) constitutes a sea-island structure in which the convex portion is an island portion and the concave portion is a sea portion, and the inner particles are present in the sea portion of the sea-island structure in a large amount in the anti-glare layer. Therefore, the surface uneven shape of the optical layered body of the first aspect of the invention has a shape in which the uneven shape is randomly present and is large and smooth. The optical layered body 1 of the first aspect of the present invention having such a surface uneven shape has a specific surface haze, which not only prevents the reflection or glare of the exterior scene, but also prevents the occurrence of moiré or contrast between the lattice pattern of the display pixel and the contrast. Very good for the reproducibility of the viewing or image color. In the phase-separated structure, irregularities are likely to be regular, resulting in moiré caused by interference with the lattice pattern of the pixels of the display, but in the first invention, ## is formed by the above-described phase separation structure (4) In the sea portion (concave portion) of the sea-island structure, a large number of internal particles are present, and the concavo-convex shape (B) formed by the internal particles is formed in the sea portion, so that the regularity of the concavities and convexities can be alleviated. 201124278 The surface of the anti-glare layer in the dry-laid layer of your moon is not only the use of the binder tree convex stone, "the phase separation of the tree, but also the formation of internal neighboring objects. By. Therefore, it is suitable for the network. The above-mentioned effects can be obtained by controlling the uneven shape of the surface of the field and appropriately controlling the inside of the layer. Further, the position of the light and the 四(四) particles of the present invention can be easily determined by optical observation and transmission observation of the dicing layer in the laminate in the first month. In addition, the surface unevenness in the optical layered body of the present invention is the same as that of the second embodiment of the present invention, and the surface of the anti-glare layer in the laminated body is the same as that of the second embodiment of the present invention. The main conditions are those. (4) In addition, the surface unevenness of the antiglare layer of the optical laminated body of the second aspect of the present invention having the above-mentioned uneven shape and the uneven shape (Β) is compared with the previous antiglare layer. Controlled to a smoother shape. Therefore, the surface unevenness of the optical layered body of the second invention is a flat α and a random shape. The optical layered body of the second aspect of the present invention having such a surface uneven shape has a specific surface haze, which not only prevents the reflection of the outside scene or the glare A, but also appropriately prevents the moiré caused by the interference with the lattice pattern of the display material. The generation or the decrease in contrast is excellent in the reproducibility of the viewing property or the color of the image. In the phase separation structure, since the irregularities are likely to be regular, resulting in moiré caused by interference with the lattice pattern of the display pixels, it is preferable to use the concave portion (A) concave portion formed by the phase separation structure. The uneven shape (B) formed by the internal particles is formed to alleviate the above regularity. 201124278 The surface unevenness of the antiglare layer in the optical laminate of the second invention is formed not only by phase separation of the binder resin but also by internal particles. Therefore, the uneven shape of the surface can be appropriately controlled, and the light scattering property inside the layer can be appropriately controlled, so that the above effects can be obtained. Specifically, the ten-point average roughness Rz of the surface uneven shape of the above anti-glare layer is less than 3 μηη. If the ten-point average roughness Rz is 3 or more, the black feeling and the contrast are lowered. The above ten-point average roughness Rz is preferably 0, 1 μπ or more and 2 μπι or less. By having such a surface uneven shape, it is possible to perform an image display with excellent blackness and high contrast. In the optical layered body according to the second aspect of the invention, the surface uneven shape of the antiglare layer is more preferably a ratio of the Rz to the arithmetic mean roughness Ra (Rz 约 is less than about 12. The arithmetic mean roughness Ra is an entire unevenness). In contrast, the ten-point average roughness Rz is selected from five points from the height of the convex portion, and five points are selected from the height of the concave portion. The average value of the difference between the height of the portion and the concave portion. Therefore, the above-mentioned ratio of the ratio of the ratio of the ratio to the height of the whole portion indicates the height of the average of the whole portion, and a part of the convex portion (or the concave portion) is higher (or lower), which indicates that the convex portion is convex. The height of the part (or the recess) is not uniform and the unevenness is large. In this case, the larger convex portion (or the convex portion (or the concave portion) of the concave portion is mixed, and the larger convex portion (or the concave portion) is less favorable for the contrast than the glare's convex portion (or the concave portion). Therefore, in the optical layered body of the invention, the ratio (Rz/Ra) is preferably less than 12, more preferably less than 1 Å. Further, the optical laminate of the second invention In the above-mentioned anti-glare layer, the surface irregularities of the surface of the surface of the above-mentioned anti-glare layer are preferably 24 or less. If the sharpness is higher than 4', the sharpness of the unevenness is high, so that the inclination angle is locally changed. The large-light diffusion becomes strong, so there is a flaw in the contrast (blackness). The above Rku is preferably 3 or less. In addition, the above-mentioned RZ, Rku, and Ra can use a three-dimensional surface shape roughness measuring machine (Zygo Corporation). In the optical layered body of the first and second aspects of the present invention, it is possible to appropriately prevent the reflection or glare of the exterior scene by having the above-described specific surface unevenness. Moire generation or contrast reduction In addition, since the layer having such a function can be formed in one layer, the manufacturing steps can be simplified, and the manufacturing cost can be reduced.

Since the anti-glare layer has such a specific surface unevenness shape, it is possible to prevent reflection by external light reflection and prevent glare, and there is no decrease in contrast, and an optical layered body excellent in visibility and color reproducibility can be formed. . The uneven shape (4)' formed by phase separation of the binder resin constituting the antiglare layer means that the composition is formed by at least two kinds of binder resins, for example, phase decomposition (spin〇dal仏(10) pottery The uneven shape formed by phase separation and the like is formed by a microscope when the internal particles are not contained.
