Description

201213883 6. TECHNOLOGICAL FIELD OF THE INVENTION The present invention relates to an optical layered body, a polarizing plate, a display device, and an optical layered body characterized in that a second phase is concentrated around particles of an optical functional layer constituting an optical layered body. Manufacturing method. The optical laminate of the present invention may be disposed on a display surface of a liquid crystal display (LCD), a plasma display (PDP), an organic electroluminescence display (OLED), or the like, or used as a constituent member of the display, in order to constitute an OLED. The emission rate of light generated in the organic EL layer to the outside of the organic EL is improved, and it can be favorably used on the side of the observation surface. In particular, the optical layered body which is excellent in the anti-glare property and the black and dark room contrast under the bright room can be suitably used for, for example, a display for television use. [Prior Art] A display device such as a liquid crystal display (LCD) or a plasma display (PDP) is reflected by an indoor illumination such as a fluorescent lamp, an incident of sunlight from a window, a shadow of an operator, or the like on the surface of the display device. The image recognition is disturbed. Therefore, in order to improve the visibility of the image on the surface of these displays, it is possible to provide a small surface on which the surface reflection light can be diffused, the specular reflection of the external light can be suppressed, and the reflection of the external environment (with anti-glare property) can be prevented. A functional film such as an optical laminate of a concave-convex structure. These functional films are usually produced and sold on a light-transmitting substrate such as polyethylene terephthalate (hereinafter referred to as "PET") or cellulose triacetate (hereinafter referred to as "TAC"). The film of the optically functional layer of the uneven structure and the film of the low refractive index layer laminated on the light-diffusing layer, and the functional film-off which provides the desired function by the combination of the layer configuration 4 322931 201213883 - is in progress. In the case where an optical layered body is used on the outermost surface of the display, when the bright room 1f7 is used, the image displayed in black due to the diffusion of light is somewhat whitened and the contrast is lowered. Therefore, there is a need for a high contrast &amp; optical laminate (high contrast ag) even if the anti-glare property is lowered. A method of improving the contrast of the optical layered body, for example, is to optimize the uneven shape of the surface. As a method of forming the uneven shape on the surface of the optical functional layer, the optical functional layer forming material is irradiated with ultraviolet rays to form an optical functional layer after coating a coating material for forming a micro (tetra) optical functional layer on a light transmissive substrate. See, for example, the patent document 丨). In addition, there is a method of optimizing the anti-glare property and the contrast by optimizing the particle size of the micro-tribes and the surface unevenness (inclination angle) contained in the optical functional layer (see, for example, Patent Document 2). In addition, a method of forming a band-like structure by using a phase separation property of the resin component by using a plurality of resin components to form an anti-glare property and a contrast ratio (see, for example, Patent Document 3). [Prior Art] [Patent Document] Patent Document 1: Japanese Laid-Open Patent Publication No. Hei. No. 2008-196156 (Patent Document No. JP-A-2008-158536). 201213883 [Problem to be Solved by the Invention] As disclosed in Patent Document 1, an anti-glare property and an anti-glare effect are achieved in the case of using an optical functional layer containing fine particles. However, since the interface of the fine particles contained in the optical layer and the optical unevenness of the surface of the optical layer based on the shape of the fine particles are scattered, it is difficult to achieve a high problem. As in Patent Document 2', even when the particle diameter of the fine particles and the inclination angle of the surface unevenness are optimized, there is a problem that the contrast is insufficient. According to Patent Document 3, there is a problem in terms of manufacturing stability in the method of forming a strip-shaped convex portion on the surface by phase separation using a plurality of resin components. In view of the above, it is an object of the present invention to provide an optical layered body which is excellent in blackness, which is excellent in black color, and which is excellent in manufacturing stability, and which is excellent in manufacturing stability. method. Another object of the present invention is to provide a polarizing plate and a display device which are resistant to the optical layered body.

[Effect of the Invention] According to the present invention, it is possible to provide an optical layered body having excellent structure which is excellent in not only anti-glare properties and bright black, but also capable of achieving high darkroom contrast, and a method for producing the optical laminate. . Further, according to the present invention, it is possible to provide an optical layered body which can be suitably used for television use for contrast. Same Embodiments [Embodiment] Hereinafter, the present invention will be described. The optical functional layer constituting the present invention has an aggregate structure. Fig. 1 is a view schematically showing the structure of an optical functional layer. (a) and (b) are plan views showing the surface structure of the optical functional layer, (phantom and illusion 322931 201213883 is a side cross-sectional view showing the side cross-sectional structure of the optical laminate. The optical layer of the conventional island structure, (6) and (d) is an optical functional layer having a random aggregation structure. Since the optical functional layer constituting the present invention is only required to have at least a first phase and a second phase, the optical functional layer may have a third phase and a fourth phase. The number of phases constituting the optical functional layer is not limited. For example, the optical functional layer may have a camera structure, and specifically, other phases (for example, the third phase) may be formed on the unevenness of the optical functional layer 16 of (1). The optical functional layer constituting the present invention has at least a first phase 含有 containing a relatively large amount of a resin component and a relatively small amount of the resin component (containing a relatively large amount) as shown in the first (13) and (d) of the present invention. The second phase 2 of the inorganic component. The second phase 2 each has a different size and shape. The first phase and the second phase constituting the optical functional layer are intricately present in a three-dimensional space. The microparticles 3 are present in the optical functional layer 16 of the invention. There is almost no first phase 1 constituting the optical functional layer 16 around the microparticles 3, and there is a second phase 2. That is, the second phase 2 is concentrated in the constituent optics. The periphery of the fine particles 3 of the work layer 16 is concentrated around the fine particles 3 by laser microscopy, SEM (scanning electron microscope), or EDS (energy dispersive X-ray spectroscope). "The second phase is concentrated around the particles, and is judged based on the SEM results observed from the optical function level of the optical laminate. First, particles of any 1 point are selected from the SEM results. Then, from the center of each particle The ratio of the second phase to the first phase and the second phase existing in the concentric circle of 10 times the long axis of the particle is obtained. Next, it is calculated in the concentric circle of 10:32931 8 201213883 The average of the proportion of the second phase. If the mean value is relatively high compared to the comparison control, then the "second phase is concentrated around the particle" is satisfied. 'If the average value is relatively low compared to the comparison control, Then The second phase is not concentrated around the particles, and the comparison is obtained based on the above SEM results. The comparison control centered on a certain point of 10 points existing in the first phase and corresponds to 10 times the long axis of each of the above particles. In the concentric circle, all the points of 10 points are placed in the concentric circle where no particles are present, thereby calculating the average value of the ratio of the second phase in the same circle to the 10 point. In the present invention, the 'optical functional layer includes a first phase and a second phase, and the random agglomerated structure means that the first phase and the second phase are intricately existing in a three-dimensional space, and the second phase is concentrated on a specific structure around the particles. As shown in Fig. 1(c), the optical function layer 15 is conventionally formed on the light-transmitting substrate 20 by the shape of the fine particles 3〇 and 3丨. In other words, since the resin present on the particles 30, 31 is convex due to the shape of the particles, the portion of the resin 40 in the absence of the particles 30, 31 is not convex, so that the convex portion and the concave portion are alternately formed, The surface unevenness of the optical function layer 15 is a structure having a large slope. Further, in the first drawings (a) and (c), when a plurality of fine particles are aggregated to form surface unevenness, the surface unevenness is also a structure having a large slope. In contrast to the optical functional layer 16 of the present invention, since the second phase 2 is concentrated around the microparticles 3, compared with the optical functional layer shown in Figs. 1(a) and (c) It can reduce fine irregularities, thereby improving high anti-glare and black under the bright room. This is due to the fact that the light constituting the present invention 9 322931 201213883 = functional layer, because the formation of the first phase is relatively flat = one phase increases both the black under the bright room and achieves a high darkroom contrast: The particles form a convex portion, and (4) the particles entering the first phase reach an anti-glare effect. The first -= is concentrated in the circumference of the microparticles, so that the microparticles are present, and the shape of the concavities and convexities will increase in multiple places in the optical functional layer.] Therefore, the optical functional layer will be whitish: concave = optical functional layer of the microparticles, due to It is difficult to control the amount and height, etc., which makes manufacturing difficult and therefore not good. The optical functional layer constituting the present invention may be a main structure as long as it is a main structure, for example, a m-aggregation structure may be partially formed as a structure, and a pseudo-aggregation structure formed in the invention may be gold. After the tomb, after the particles contained in the Li functional layer formed by the surface irregularities are formed, the element of the random agglomerated structure formed in the carbonaceous surface can be roughly observed. The number of elements has a large number of elements, and there are elements of the multi-element 41-, the atomic number of the element is not white, the atomic number is small, and the color of the element I: black is distinguished by the color. Further, in the case where the surface of the optical functional layer and the random aggregation junction formed in the present invention were subjected to EDS surface scanning, it was confirmed that an element existing in the cross section of the coating film (optical functional layer) was coated. EDS surface sweep 322931 10 201213883, the color can be displayed in places where specific elements (such as carbon, oxygen, strontium, etc.) are distributed. 77 By using the above electronic display In the observation of the micromirror and the EDS surface scanning, it is possible to confirm the uneven structure of the random aggregate structure and the distribution of the specific elements. Thus, for example, it is possible to confirm that there is a majority distribution of a specific element in the convex portion of the surface unevenness. Fig. 4 is a more detailed description. Fig. 2 and Fig. 4 are diagrams showing the surface state of the optical functional layer produced in the embodiment described later in the same field of view. The optical functional layer is composed of a resin component. The inorganic component and the fine particles are composed. Fig. 2 is a photograph of a carbon vaporization clock on the surface of the optical functional layer. The image displayed in the reflected electron detector is a reflection electron caused by a component contained on the surface of the optical functional layer. The reflection electron 疋 is related to the atomic number, and can be displayed by, for example, a color indicating that the element having a large atomic number is displayed as white, and an element having a small atomic number is displayed as black, etc. As shown in Fig. 2, the optical functional layer is shown. The elements in the middle are not, the average sentence exists in the horizontal direction of the surface, but the relatively large part and the relatively small content of the element 3 with a large atomic number. Fig. 4 is a diagram showing the results of the surface scan of the inorganic knives (Si) obtained by passing the legs on the surface of the optical functional layer, and the amount of the &amp; component contained is indicated by the concentration/inflammation of the color. As shown in Fig. 4, the composition is also composed of a relatively relatively large portion and a relatively small content. Further, in Fig. 4, 7 is specifically exemplified to show the surface of the stone (Si). Although the results of the scanning are shown in Table 7F, the results of the scanning of other inorganic component elements and resin (organic) components are 322931 11 201213883. The surface scanning conditions shown in Fig. 4 are m inorganic materials, &quot;also detected: :::: Optical with two phases of the first phase and the second phase: :: Layer: 'First: contains 90% by mass or more of the resin component and inorganic knives, and the second phase contains less than 99.8 masses 0/〇 The resin component and the inorganic component above the enamel. The resin component contained in the first phase is preferably 95 mass% / 2, and the stepwise step is preferably 99 mass% or more. The J-component contained in the second phase is preferably 1% by mass or more. The amount of the J-component is preferably 5% by mass or more. It is particularly preferably 1% by mass or more. The resin component contained in the second phase is preferably less than 99% by mass, and is preferably less than 95% by mass, particularly preferably less than 90% by mass. The amount of the inorganic component contained in the optical functional layer is more than that in the second phase. In the portion where the content of the resin component is relatively large (the knife having a rich color in Fig. 2), the content of components other than the resin component is relatively decreased (first phase). On the other hand, in the portion where the content of the resin component is relatively small (the portion having a light color in Fig. 2), the content of components other than the resin component is relatively increased (second phase). That is, the optical functional layer of the present invention is a layer in which the first phase and the second phase are intricately present, and is a layer having a complementary relationship in which one component is decreased and the other components are increased. In addition, FIG. 2 and FIG. 4 are diagrams showing the content of each component in the horizontal direction of the surface of the optical functional layer, and the same can be applied to the content of each component in the vertical direction (thickness direction) of the optical functional layer. The results of the complementary relationship shown in Table 12 322931 201213883 are obtained (Fig. 3). <Method of Forming Random Aggregation Structure> The random aggregation structure of the month can be randomly collected by convection of the inorganic component, and around the particles = and the first, the money component, the micro (four), (the first solvent U a solution of the agent, a solvent (the volatilization of the i-solution, a (4) step, and a hardening step of forming the optical functional layer.

Further, in the case of a PDP or an LCD, one selected from the group consisting of a PET film, a TAC film, and a norbornene-containing resin film is preferably used. The higher the transparency of the light-transmitting substrate, the better the transparency, and the total light transmittance (JISK7105) may be 80% or more, and more preferably more. Further, the thickness of the light-transmitting substrate is preferably a thin plastic mold from the viewpoint of weight reduction, and in consideration of productivity and workability, it is preferable to use a substrate having a range of 丄 to 7 〇〇//m.
