Field of the Invention The present invention relates to an anti-glare film, a method of manufacturing the anti-glare film, a polarizing plate, and an image display device. In an image display device such as a cathode ray tube display device (CRT), a liquid crystal display (LCD), a plasma display (PDP), an electroluminescence display (eld), or an electronic paper, an antireflection optical is usually disposed on the outermost surface. Laminated body. Such an optical laminate for antireflection suppresses reflection of an image or reduces reflectance by diffusion or interference of light. As one of the optical laminates for antireflection, an antiglare film having an antiglare layer having an uneven shape is formed on the surface of a transparent substrate. The anti-glare film can prevent the visibility from being degraded by diffusing external light by utilizing the uneven shape of the surface. Further, such an anti-glare film is usually provided on the outermost surface of the image display device, and therefore a certain degree of hard coat property is also required. An anti-glare layer formed by a resin such as a filler (for example, a reference patent)

另外，擴散層所含之凝聚體會反射外光而產生褪色。另一 方面，若超過70。，則形成於與上述凝聚體對應之位置的擴 散層表面之凸部會變得過大，而出現本發明之防眩膜產生 褪色、產生閃爍之問題。上述傾斜角之更佳下限為3〇。，更 佳上限為60。。藉由上述傾斜角為上述範圍内，而防眩性 能、防褪色性及防閃爍性能之平衡極為優異。 再者，於本說明書中，將上述傾斜角未達2〇。時視為2

201139140 若形成上述凝聚體之微粒子（A )未達5〇%，則本發明 之防眩膜之防眩性能不充分，或者無法充分抑制褪色之產 生或閃爍之產生。形成上述凝聚體之微粒子（A )之比例之 較佳下限為65%，更佳下限為8〇%。若形成上述凝聚體之 微粒子（A)之比例的下限為65%，則防眩性與防褪色性能 更佳，若上述比例之下限為8〇%，則可獲得充分之防眩性 與對比度。 再者，上述擴散層中未形成上述凝聚體之微粒子（A) 未達50/。。即亦可作如下規定，上述擴散層中，於上述區 域内，單粒子狀微粒子（A)之數量、構成2個微粒子⑷ 相對於透光性基材之表面垂直或平行地凝聚而成之凝聚體 的微粒子（A)之數量、及構成3個以上微粒子（A)凝聚 而成之凝聚體的微粒子（A )之數量的合計，於隨機測量2〇 個微粒子（A )時為未達1 〇個。 此種微粒子（A)，較佳為不因上述塗液中之放射線硬 化型黏合劑及/或溶劑而膨潤之粒子。 此處，所謂「不膨浪1之粒子」，除了完全不因上述放射 線硬化型黏合劑及/或溶劑而膨潤之情況外，#包括微微 膨潤之情況。上述「微微膨潤之情況」係指如下情況：於 上述擴散層中，雖然於上述微粒子（A)形成與後述有機微 粒子（B)相同之含浸層，但該含浸層之平均厚度小於有機 微粒子（B)令所形成之含浸層，且未達〇丨“爪。 至於上述擴散層中之微粒子（A)是否形成含浸層之判 斷’例如可藉由利用顯微鏡（SEM等）觀察上述擴散層之 201139140 微粒子（A)之剖面來進行β 再者，於以下說明中，亦將上述擴散層中之微粒子 稱為「微粒子（Α2)」^ 上述不因放射線硬化型黏合劑及/或溶劑而膨潤之微 粒子（A ) ’例如可列舉：蕤山__结 曰一氧化矽被粒子等無機粒子， 或聚苯乙稀樹脂、三聚氰胺樹脂、聚醋樹脂、丙烯酸樹脂、

微粒子之情形進行制i者，本說明書巾，「樹脂」亦包 括單體、暴聚物等樹脂成分之概念。 此處，丙烯酸樹脂、聚苯乙烯樹脂及丙烯酸-苯乙烯 共聚物構成之有機微粒子，於藉由通常所知之製造方法來 製造時，均使用丙烯酸一苯乙烯共聚合樹脂作為材料。另 外，上述微粒子若為核—殼型，則存在：核使用由丙稀酸 ，所構成之微粒子之聚苯乙烯微粒子、或反之核使用由 苯乙烯樹脂所構成之微粒子之丙烯酸微粒子。因此，本說 明書中，對於丙烯酸微粒子、聚苯乙婦微粒子及丙稀酸— 苯乙烯共聚合微粒子之區分，係藉由微粒子所具有之特性 (例如折射率）最接近於哪種樹脂來判斷。例如，若微粒 12 201139140 子之折射率未達1 ·50 ’則可視為丙烯酸微粒子，若微粒子 之折射率為丨_5〇以上且未達1.59，則可視為丙烯酸一苯乙 稀共聚物微粒子’若微粒子之折射率為1 5 9以上，則可視 為苯乙稀微教子。 另外，以下對於微粒子有「高交聯」、「低交聯」之情 形，該「高交聯」、「低交聯」係按以下方式進行定義。 製備以下塗液：相對於放射線硬化型黏合劑（新戊四 醇三丙稀酸酿（ΡΕΤΑ)、二新戊四醇六丙烯酸酯（dPhA) 及聚甲基丙烯酸甲酯（ΡΜΜα )之混合物（質量比；ρΕΤΑ /DPHA/PMMA= 86/5/9)) 1〇〇 質量份，摻合 190 質量 份之曱苯與曱基異丁基酮之混合物（質量比8 : 2 )。 將微粒子浸潰於所得塗液24小時，將發現膨潤之微粒 子疋義為「低交聯」，將未發現膨潤之微粒子定義為「高交 聯」。 此處，如上所述，為了使防眩膜發揮充分之防眩性能， 車乂佳為於擴散層之表面形成較大之凸部，例如，若擴散層 含有大粒徑之微粒子，則可容易地於擴散層之表面形成較 大之凸部。然而，於擴散層含有大粒徑之微粒子時，直表 面會變成粗链之狀態（產生應用本發明之防眩膜而成：顯 示器之影像的輪廓模糊等影像缺乏緻密度之粗糙性，晝質 缺乏緻密度而降低之狀態）而使晝質降低。另外，為了防 止微粒子脫落等，而必須加厚擴散層，因此存在所形成之 防眩膜產生捲縮，或者產生因擴散層形成時之黏合劑成分 之硬化收縮等而引起的龜裂之問題。 13 201139140 本發明者等人著眼於此種擴散層之防眩性能與所含有 u粒子之大小的關係，進行探入研究之結果係，藉由選擇 相對較小之微粒子作為擴散層所含有之微粒子，並且使該 微粒子於擴散層中成為特定的凝聚形態，而可避免選擇上 述大粒徑微粒子時之問題，並且製成能發揮充分防眩性能 之防眩膜。 即，本發明中，作為上述擴散層所含有之微粒子（A)， 與先前為了發揮充分之防眩性能而添加之微粒子相比，而 選擇更小粒徑者。 上述微粒子（A)之平均粒徑，具體而言較佳為0.5〜 1〇.0以01之範圍者。若未達〇.5 A

In addition, for example, Patent Document 4 describes an optical layered body in which the total fog value and the internal haze value are in a specific relationship, and the antiglare layer having the uneven shape on the outermost surface contains the agglomerated fine particles. The antiglare layer described in 4 does not investigate the control of the state of aggregation of the fine particles, and the aggregate containing the large f is aggregated in the thickness direction of the antiglare layer or in the in-plane direction of the antiglare layer: The optical layered product described in Patent Document 4 has a problem that a large number of large convex portions are formed on the surface of the anti-glare layer, and the production of fading cannot be sufficiently controlled, and so-called flicker is also generated.

Further, the present invention provides an image display apparatus comprising: an anti-glare film of the present invention or a polarizing plate of the present invention on the outermost surface. The present invention will be described in detail below. 201139140 The anti-glare film of the present invention has light transmissivity. a substrate, and a diffusion layer formed on the light-transmitting substrate: a surface having an uneven shape on one surface. The light-transmitting substrate preferably has The sliding property, the heat resistance, and the mechanical strength are excellent.

The above-mentioned light-transmitting substrate is preferably made into a flexible film-like body and used in the form of hardening according to requirements, and the thermoplastic tree can also be used. Use the plate-shaped body of the glass plate. The thickness of the light-transmitting substrate is preferably 2 〇 to 3 〇〇 / / m, more preferably the upper limit is 200 hearts, and the lower limit is 3 〇 _. When the light-transmitting substrate is a plate-shaped body, the thickness may exceed the thickness. Further, when the light-transmitting substrate is formed with an antiglare layer thereon, in order to improve the adhesion, in addition to the physical treatment such as the corona discharge treatment, such as electric power treatment, saponification treatment, or oxidation treatment, the fixing agent may be previously prepared. (anchor ageiU) or coating of a coating known as Primer. In the above-mentioned diffusion layer, the diffusion layer containing fine particles and containing (meth)acrylic acid vine monomer as an essential component is hard, and the coating liquid of the agent is applied to at least the above-mentioned light-transmitting substrate. A surface is dried to form a coating film, and the coating film is cured. 201139140. In addition, in the present specification, the term "monomer" includes all of the polymer film formed for the purpose of performing free radiation hardening, and may be the polymerization. The molecule of the constituent unit of the basic structure of the film, that is, if the polymer or prepolymer is a basic unit of the cured film, it also includes a polymer or a prepolymer. In the present invention, the above monomer is preferably a weight. In the present invention, the diffusion layer is a cured coating layer unless otherwise specified. The fine particles (A) are provided in the diffusion layer. The internal diffusion function and the fine particles having the function of forming the convex portion on the surface of the diffusion layer. Fig. 1 is a cross-sectional view showing the state of the aggregate in the diffusion layer, as shown in Fig. 1. The antiglare film of the present invention is shown in Fig. 1. 10 is formed in the diffusion layer 12 formed on at least one surface of the light-transmitting substrate 11 to form an agglomerate in which two microparticles (A) 13 are aggregated. "Two microparticles (A) u forming the agglomerate are The straight lines connecting the centers of the ones are condensed at an oblique angle with respect to the surface of the light-transmitting substrate u. Since the diffusion layer has such agglomerates, the anti-glare film of the present invention is anti-glare! In the anti-glare film of the present invention, the fine particles (A) in the diffusion layer are formed to connect the centers of the centers with respect to the light-transmitting substrate. The two agglomerates in which the surface is slanted at an angle of inclination. The above-mentioned "straight line connecting the centers of the centers" means a cross section in which the diffusion layer of the anti-glare film 201139140 of the present invention is cut along the thickness direction thereof, and the connection constitutes the above-mentioned A straight line at the center of the shape depicted by the cross section of the two microparticles (a) of the agglomerate. The above-mentioned "center of the shape depicted by the cross section" is generally referred to as a circle by the shape of the cross section, and thus refers to the center of the circle, and the shape depicted by the cross section is a circle other than the center of gravity of the cross section. Further, it is preferable that the two microparticles (A) constituting the agglomerate are connected to each other at a center line and have an inclination angle of 20 to 70 with respect to the surface of the light-transmitting substrate. If it does not reach 2〇. The anti-glare film of the present invention has poor anti-glare properties, and the aggregates contained in the diffusion layer reflect external light to cause fading. On the other hand, if it exceeds 70. Further, the convex portion formed on the surface of the diffusion layer at the position corresponding to the agglomerate may become excessively large, and the antiglare film of the present invention may cause fading and flicker. A more preferable lower limit of the above inclination angle is 3 〇. The upper limit is 60. . When the above inclination angle is within the above range, the balance between the antiglare property, the fading resistance, and the anti-flicking property is extremely excellent. Furthermore, in the present specification, the above inclination angle is less than 2 〇. In the case of the two fine particles (A) phase, the surface of the light-transmitting substrate t is agglomerated in parallel, and the above-mentioned inclination angle exceeds 70. It is considered that two fine particles (A) are vertically aggregated with respect to the surface of the light-transmitting substrate. In the antiglare film of the present invention, 50% or more of the fine particles (VIII) in the diffusion layer form the aggregate. Here, the above-mentioned "50% or more of the above-mentioned aggregates" means that when the microparticles (A) are randomly observed in the cross section of the diffusion layer by microscopic observation such as §εμ or a transmissive 'reflective optical microscope, more than one is obtained. The microparticles (a) form the above-mentioned aggregates. 201139140 If the fine particles (A) forming the agglomerates are less than 5%, the antiglare property of the antiglare film of the present invention is insufficient, or the generation of fading or the occurrence of flicker cannot be sufficiently suppressed. A preferred lower limit of the ratio of the fine particles (A) forming the agglomerates is 65%, and a lower limit is more preferably 8 %. When the lower limit of the ratio of the fine particles (A) forming the agglomerate is 65%, the anti-glare property and the anti-fading property are more preferable, and when the lower limit of the above ratio is 8 %, sufficient anti-glare property and contrast can be obtained. Further, the fine particles (A) in which the agglomerates are not formed in the diffusion layer are less than 50/. . In other words, in the above-mentioned diffusion layer, the number of the single-particle fine particles (A) and the condensation of the two fine particles (4) perpendicularly or in parallel with respect to the surface of the light-transmitting substrate may be condensed in the above-mentioned region. The total number of the fine particles (A) and the number of the fine particles (A) constituting the aggregate of the three or more fine particles (A) are less than 1 when randomly measuring 2 particles (A). One. Such fine particles (A) are preferably particles which are not swollen by the radiation-hardening binder and/or solvent in the coating liquid. Here, the "particles of non-swelling wave 1" include a case where it is slightly swelled except that it is not swelled by the above-mentioned radiation-curable adhesive and/or solvent. In the case of the above-mentioned diffusion layer, the fine layer (A) forms the same impregnation layer as the organic fine particles (B) described later, but the average thickness of the impregnation layer is smaller than that of the organic fine particles (B). The impregnation layer formed is formed so as not to "claw. As to whether or not the microparticles (A) in the diffusion layer are formed to form an impregnation layer", for example, the 201139140 microparticles of the diffusion layer can be observed by a microscope (SEM, etc.). In the cross section of (A), the fine particles in the diffusion layer are also referred to as "fine particles (Α2)". The above-mentioned fine particles which are not swollen by the radiation-curable adhesive and/or solvent ( A) 'For example, inorganic particles such as 蕤 _ 曰 曰 曰 曰 矽 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , 无机 无机 无机 无机 无机 无机 无机 无机 无机 无机Organic microparticles to increase the degree of crosslinking, etc. These fine particles (Α) may be used singly or in combination of two or more. ▲ Among them, it is preferable to easily control the refractive index or the particle size of the organic fine particles, and it is easy to set the refractive index difference with the radioactive hardening type adhesive (the refractive index of the radiation hardening type adhesive is about 54). In order to use melamine microparticles, polystyrene microparticles, and/or acrylic acid-styrene copolymer microparticles [further, the following is the case where microparticles (Α) are organic microparticles, the specification sheet, "resin" also includes The concept of resin components such as monomers and biopolymers. Here, the organic fine particles composed of an acrylic resin, a polystyrene resin, and an acrylic-styrene copolymer are all made of a styrene-acrylic styrene copolymer resin as a material when produced by a generally known production method. Further, when the fine particles are of a core-shell type, there are acrylic fine particles in which the core is made of polystyrene fine particles composed of acrylic acid or microparticles composed of a styrene resin. Therefore, in the present specification, the distinction between the acrylic microparticles, the polystyrene microparticles, and the acrylic acid-styrene copolymerized microparticles is judged by which resin (e.g., refractive index) of the microparticles is closest to which resin. For example, if the refractive index of the particles 12 201139140 is less than 1 · 50 ', it can be regarded as acrylic microparticles. If the refractive index of the microparticles is 丨_5〇 or more and less than 1.59, it can be regarded as acrylic styrene copolymer microparticles. If the refractive index of the fine particles is 159 or more, it can be regarded as a styrene micro-teacher. In addition, in the following, there are cases of "high cross-linking" and "low cross-linking" for the fine particles, and the "high cross-linking" and "low cross-linking" are defined as follows. The following coating liquids were prepared: a mixture of a radiation hardening type binder (neopentitol triacrylic acid (ΡΕΤΑ), dipentaerythritol hexaacrylate (dPhA), and polymethyl methacrylate (ΡΜΜα) ( Mass ratio; ρΕΤΑ /DPHA/PMMA= 86/5/9)) 1 part by mass, blended with 190 parts by mass of a mixture of terpene and decyl isobutyl ketone (mass ratio 8:2). When the fine particles were immersed in the obtained coating liquid for 24 hours, it was found that the swelled microparticles were "lowly crosslinked", and the pulverized microparticles were not defined as "highly crosslinked". Here, as described above, in order to provide the antiglare film with sufficient antiglare performance, the rut preferably forms a large convex portion on the surface of the diffusion layer. For example, if the diffusion layer contains fine particles having a large particle diameter, it is easy. A large convex portion is formed on the surface of the diffusion layer. However, when the diffusion layer contains fine particles having a large particle size, the straight surface becomes a state of a thick chain (the anti-glare film to which the present invention is applied is formed: the image of the display is blurred, and the like, the image lacks the roughness of the density, and the enamel The lack of density and reduced state) reduces the quality of the enamel. Further, in order to prevent the fine particles from falling off and the like, it is necessary to thicken the diffusion layer. Therefore, the formed anti-glare film is curled or cracked due to curing shrinkage of the binder component at the time of formation of the diffusion layer. 13 201139140 The inventors of the present invention have focused on the relationship between the antiglare property of such a diffusion layer and the size of the contained u particles, and the results of the investigation have been made by selecting relatively small particles as the microparticles contained in the diffusion layer. Further, the fine particles are allowed to have a specific agglomerated form in the diffusion layer, and the problem of selecting the above-mentioned large-sized fine particles can be avoided, and an anti-glare film which exhibits sufficient anti-glare performance can be obtained. In other words, in the present invention, the fine particles (A) contained in the diffusion layer are selected to have a smaller particle diameter than the fine particles previously added to exhibit sufficient antiglare performance. The average particle diameter of the fine particles (A) is preferably in the range of 0.5 to 1 〇.0 to 01. If it is less than .5 A m, the above-mentioned aggregates cannot be formed in a specific ratio, and the antiglare property of the antiglare film of the present invention is insufficient. On the other hand, if it exceeds, the concavo-convex shape formed on the surface of the diffusion layer becomes large, and the anti-glare m of the present invention produces #色或_. More preferably, the limit is l_〇V m, and the upper limit is 8 m. "Further, the average particle diameter of the above-mentioned fine particles is (4) in the coating film, and the shape of each of the microparticles contained in the microparticles is a single particle, and the arithmetic mean "if it is an amorphous microparticle having a wide particle size distribution" The following refers to the particle size of the fine particles which are most present according to the particle size distribution measurement. The particle control is measured in the form of only the fine particles, and can be measured by the Coulter's microparticles " The particles present in the coating film are too large, moist, etc., and exhibit a particle diameter different from that of the powder state. Therefore, the above-mentioned fine particles (particles in the diffusion layer of the anti-glare film of the present invention are preferably passed through a transmission type optical microscope. Observation or cross-section (4) Photograph 14 201139140 Measured by photographing. In the anti-glare film of the present invention, when the average particle diameter of the fine particles (A) forming the aggregates is D a , the tilt of the two fine particles (A) is In the positional relationship of the angles, when the two microparticles (a) forming the agglomerate are connected to each other, the inclination angle of the straight line of the 'u and the surface of the light-transmitting substrate is defined as 0, and the two microparticles (A) are adjacent to each other. Thickness of the condensate The height of the direction is: l//2DA+DAsin0 + 1/2DA= DA(1 + sin^ ) 〇 At this time, if the approximate value of sin20o* 〇_34, sin70o and 0.94 is used, the inclination angle is 20. The height in the thickness direction is (丨34xDa), and the inclination angle is 70. When the height of the aggregate in the thickness direction is (), the positional relationship between the DA and the thickness τ of the diffusion layer is preferably such that the following formula is satisfied. (A): (1.34xDA) <T<(1.94xDa) (A). The relationship between the average particle diameter Da of the microparticles (A) forming the agglomerate and the thickness T of the diffusion layer satisfies the above formula (a) The above-mentioned aggregates can be preferably formed. That is, if the thickness of the diffusion layer is 1·34 times or less of the average particle diameter, the straight line and the light transmittance of the connection center of the two fine particles (A) constituting the aggregate are formed. The inclination angle of the surface of the substrate is too small. If it is 194 times or more, the two microparticles constituting the agglomerate. The angle between the straight line connecting the center of (A) and the surface of the light-transmitting substrate will be It becomes too large.

Further, unless otherwise specified, the above _ ^ % . , , . 1 is the average particle diameter of the diffusion layer r μ particles (A) after the hardening. In the anti-glare film of the present invention, as the fine particles (A), for example, an anti-glare is prepared by using a coating liquid of organic fine particles having different degrees of crosslinking, and an organic fine particle having a uniform degree of impregnation can be selected and used. . The content of the fine particles (Α) in the coating liquid is not particularly limited, and is preferably 〇 by mass based on 1 part by mass of the radiation-curable adhesive to be described later. If the 丨丨 5 5 5 , , , , , , 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 则 则 则 则 则 则 则 则 则 则 则 则On the other hand, if it exceeds 30 parts by mass, the contrast of the image display layer using the anti-glare film of the present invention is lowered. A lower limit of the content of the above fine particles (Α) is! The mass fraction and the better upper limit are 20 parts by mass. By being within this range, the above effects can be obtained more surely. The coating liquid preferably further contains organic fine particles (Β). The difference between the refractive indices of the organic fine particles (8) and the binder is preferably less than 0.04. The organic fine particles + ( Β ) are mainly formed on the surface of the diffusion layer at a position corresponding to the organic fine particles (β). By containing such organic fine particles, it is possible to form smooth unevenness in the formed diffusion layer and to have both anti-glare property and contrast. 16 201139140 Acrylic resin Further, in the production of fine particles, a crosslinked acrylic resin of a type in which the crosslinking density is increased to a degree of crosslinking is preferred. In addition, the organic fine particles (B) radiation-curable adhesive and/or the solvent may be exemplified by a polyoxyxylene resin, a polyester resin, an olefin resin, or the like, and are preferably described later. The agent is swelled, specifically, a resin, a stupid vinyl resin, an acryl polymer, etc., among which the "resin" may preferably include a reactive or non-reactive polymer, a monomer, and the like. The concept of a resin component such as an oligomer. Here, the organic fine particles composed of an acrylic resin, a styrene resin, and an acrylic-styrene copolymer are all produced by a commonly known production method using an acrylic-styrene copolymer resin as a material. Further, in the case where the organic fine particles (8) are core-shell type fine particles, there are (four) acid fine particles in which a nucleus of a fine particle composed of an acrylic resin is used for a core or a microparticle composed of a styrene resin is used as a core. . Therefore, the region of the present invention for the copolymerization of fine particles of propylene (tetra) fine particles, styrene fine particles and acrylic acid-styrene is judged by the properties of the fine particles (for example, the folding (four)) t which is close to which resin. For example, if the refractive index of the microparticles is not it, it can be regarded as acrylic microparticles. If the refractive index of the microparticles is i.5G or more and less than 1<59, it can be regarded as a micronized acid-styrene copolymer microparticle, and if the refractive index of the microparticle is Above 159, it can be regarded as phenethyl quinone microparticles. The crosslinked acrylic resin is preferably, for example, polymerized in an acrylic acid such as acrylic acid, acrylate, methyl acrylate or methacrylic acid acetamide, acrylamide or acrylonitrile. Starting agent and ethylene glycol dimethyl 17 201139140 A crosslinking agent such as acrylate is a homopolymer or a copolymer obtained by polymerization by a suspension polymerization method or the like. The above acrylic monomer is particularly preferably a crosslinked acrylic resin obtained by using methyl methacrylate. In addition, since the thickness of the impregnation layer to be described later can be controlled by adjusting the degree of swelling by the radiation-curable adhesive and/or solvent described later, it is preferable to change the impregnation amount of the radiation-curable adhesive to a preferable range. The extent of cross-linking. The average particle diameter of the organic fine particles (B) is not particularly limited, and may be equivalent to the average particle diameter of the fine particles (A). Preferably, however, the average particle diameter of the organic fine particles (B) in the diffusion layer is larger than the fine particles (A2) in the diffusion layer. When the average particle diameter of the organic fine particles (B) in the diffusion layer is equal to or less than the average particle diameter of the fine particles (A2) in the diffusion layer, the effect of adding the above fine particles (A) is hardly obtained. Further, preferably, when the organic fine particles (B) are in the diffusion layer as the DB, the thickness τ of the db with respect to the diffusion layer satisfies the following formula (B): db < T (8). When the average particle diameter DB of the organic fine particles (B) does not satisfy the above formula (B) thick sound P, and the average particle diameter DB of the organic fine particles (B) is equal to or higher than the value of the diffusion layer, the organic fine particles (8) On the other hand, the unevenness of the anti-glare film of the present invention is increased, and the contrast of the anti-glare film of the present invention is lowered. Particles: In the antiglare film of the present invention, it is preferable that the organic microparticles in the diffusion layer have a layer containing a radiation-curable adhesive to be described later. 18 201139140 In the following description, the organic fine particles (8) in the diffusion layer, which is the organic fine particles (8) formed in the above-mentioned impregnation layer, are also referred to as "organic fine particles ("", and the organic fine particles (B2) and the organic fine particles (B2) are The cured product of the radiation-curing adhesive of the diffusion layer (hereinafter also referred to as the adhesive resin) is excellent in adhesion, and the above-mentioned 3 π layer in the organic fine (B2) is a radiation-curable adhesive and The material constituting the organic fine particles (Β2) is formed in a mixed state, and therefore the refractive index of the above-mentioned impregnated layer becomes a refractive index between the refractive index of the radiation-curable adhesive and the refractive index of the organic fine particles (8), and can be preferably reduced as described above. The reflection of the transmitted light of the above diffusion layer at the interface between the organic fine particles (Β2) (the impregnated layer) and the binder resin. In addition, at the same time, the above-mentioned impregnation layer is a moderate layer thickness, and the organic fine particles (Β2). The refractive index of the initial organic fine particles (Β), so that internal diffusion does not decrease, and flicker can be preferably prevented. Further, as will be described later, the above-mentioned impregnation layer is used Since the radiation-curable adhesive and/or the solvent swells the organic fine particles (8), the organic fine particles (Β2) become extremely flexible fine particles. Therefore, the surface of the diffusion layer can be made with organic fine particles (Β2). The shape of the convex portion formed by the corresponding position becomes gentle. Further, this aspect will be described in more detail below. The above-mentioned impregnation layer is from the outer surface of the organic fine particles (β2) in the diffusion layer to the surface thereof. A layer formed by impregnating a radiation-curing adhesive at the center. Further, the above-mentioned impregnated layer is a layer of a low-molecular-weight forming lining, that is, a layer mainly formed by impregnating a monomer, and is a radiation-hardening type of a high molecular weight component. The polymer or oligomer of the polymer of the binder is difficult to contain 19 201139140 /X. However, even oligomers or polymers are relatively small in molecular weight' or are impregnated together when impregnating the monomer. The layer can be discriminated by, for example, microscopic observation (SEM, etc.) of the cross section of the organic fine particles (B2) in the diffusion layer. The radiation-curable adhesive impregnated in the above-mentioned impregnated layer may be all components composed of the impregnation, or may be one of the components of the impregnation. The above-mentioned impregnated layer preferably has an average thickness of 〇〇1 to 1 〇&quot If it is less than 〇·〇1 in m, the effect of forming the above-mentioned impregnation layer cannot be sufficiently obtained. If it exceeds 1.〇em, the internal diffusion function of the organic fine particles (B2) cannot be sufficiently exhibited. The anti-flicker effect is sufficiently obtained. The lower limit of the average thickness of the above-mentioned impregnated layer is 0" " m, and the upper limit is preferably 〇 8 "m. The borrowing = is within the range, and the above effects can be further exerted. It is preferable that the microparticle (B2) "the diameter of the center portion of the impregnation layer is such that the internal expansion strategy is ensured to prevent flicker. Further, the average thickness of the above-mentioned impregnated layer means the flatness of the thickness of the impregnated layer of the organic fine particles (B2) observed by the cross-section of the anti-glare film. Specifically, it is possible to observe and photograph any of the $: portions of the cross-section of the diffusion layer in which there are more than one microparticle having an impregnated layer by SEM from 3 to 50,000 times, and then to one microparticle.敎 2 places. The thickness of the layer containing is determined as the average value at the measured value of 10. The measurement of the thickness of the above-mentioned Han dynasty was carried out by selecting the boundary line of the binder resin microparticles around the two microparticles with relatively clear and maximum impregnation. Here, the organic fine particles usually have a crosslinked structure, and the degree of swelling caused by the above-mentioned radiation 20 201139140 linear hardening type binder or solvent differs depending on the degree of crosslinking, and usually, if the degree of crosslinking becomes high, the swelling degree changes. Low, if the degree of cross-linking is low, then the month " Therefore, for example, when the second organic fine particles (B) are the crosslinked acrylic resin, the thickness of the third/layer of the organic fine particles (B2) can be adjusted by appropriately adjusting the crosslinked acrylic resin. The degree of cross-linking: in the required range. In addition, in terms of anti-reflection performance and anti-flicking. More preferably, the more the above-mentioned organic fine particles (B2) is at the center portion, the more the degree of crosslinking is optimally compared to the thickness of the impregnated layer of the organic fine particles (B2), and the inner side is the degree of cross-linking of non-impregnation, and The more the surface cross-linking degree: the lower the same, the same is true for the above-mentioned fine particles (a). Further, when the average particle diameter of the organic fine particles (B) is D, and the average particle diameter of the organic fine particles (B2) in the diffusion layer is μ, the Db 1 and db2 satisfy the following formula ( 2): °-〇Um<DB2-DBl<i.0//m (7). In the above formula (7), if "Db2_d is 〇〇1^, the thickness of the j-impregnated layer becomes too thin, and the effect obtained by forming the upper third layer cannot be obtained. Very r\i B ~ Db 1" is 1 .〇# rn or more, the unevenness formed on the surface becomes too large.

It is more preferable if the solvent for swelling the organic fine particles (8) is common to the solvent of the immersion solvent, that is, if the solvent of the TAC substrate is prepared in advance, the 'machine jaws (B) having the impregnation layer are prepared in advance. The solvent used is substantially the same, and the above-mentioned coating liquid is combined with the old one, and the compound balance of the powder 3 is very stable for a long time to protect the anti-glare material, and can also be made into a stable processing and excellent coating liquid. 'It is preferably a methyl isobutyl group or the like. In addition, the resin component: the low component · is preferably neopentyl alcohol tris(meth)acrylic acid vinegar, new tetrakis quinone (mercapto) acryl vinegar, dipentaerythritol The alcohol penta (meth)acrylic acid vinegar, pentaerythritol hexa(indenyl) acrylate, etc. Further, the coating liquid preferably contains a layered inorganic compound. The reason is that the formed diffusion layer contains the above layer. The inorganic compound can improve the hard coat property, the anti-shrinkage property, the ultraviolet ray resistance, the crack resistance, and the like of the diffusion. Further, the aggregate of the fine particles (A) can be preferably formed. When the organic microparticles (8) are fascinated, the microparticles (A) will preferably condense. Further, the agglomeration of the fine particles (A) and the organic fine particles (B) can be prevented. The above-mentioned layered inorganic compound is excellent in particle size D5〇 (laser diffraction method) in order to maintain the anti-glare film of the present invention. It is 〇3~5〇ρ, more preferably 〇5~3.0, m. Since the above layered inorganic compound is a plate-like particle, since the particle diameter of 29 201139140 is D50, for example, when (10) is used as the stalactite talc, When the SEM observation of the cross section of the diffusion layer is carried out, it is found that most of the particles are about 0.6//m. The upper layered inorganic compound is not particularly limited, and examples thereof include montmorillonite, beidellite, nontronite, and soap. Stone, Zhongmeng stone, montmorillonite, Shixi town stone, vermiculite, kaolinite, kaolin, Ande stone, Dick stone, talc, pyrophyllite, mica, pearl mica, muscovite, phlogopite , Si Shi Xi Yun, with mica, serpentine, chlorite, chlorite chlorite group (nantlte), etc. These layered inorganic particles can be either a celestial surface or a composite. An inorganic compound, preferably containing an inorganic compound of α, μ§, and ◦70 The compound containing such an element is preferably talc. The fine talc is contained as the above-mentioned layered inorganic compound, for example, when the bisphenolic acid particles are used as the above organic fine particles (Β), and when styrene is used as the scorpion (A) It is preferable to control the prevention of the above-mentioned fine particles (a) in the diffusion layer: formation of aggregates, aggregation of organic fine particles (B) in the diffusion layer, and aggregation of (A) and organic fine particles (B). 'The anti-glare, anti-fading and anti-flicking properties of the anti-glare film. It is speculated that the talc is a substance with high lipophilicity. It is speculated that the microparticles (A) (styrene) are lipophilic. Organic micro: (B) (cross-linked acrylic resin) has the property of hydrophilicity, while the talc of the relatives adjusts the aggregation of the two microparticles. The above-mentioned layered inorganic compound refers to the inorganic layer which becomes a layered structure, and also includes a needle-like or fibrous shape in a cross-sectional microscope observation. 30 201139140 In addition, in the copolymerized microparticles of acrylic acid-styrene, the hydrophilicity is changed by changing Since the ratio of the acrylic component to the oleophilic styrene component is moderately hydrophilic or lipophilic, the layered inorganic compound can be easily exhibited by the above-mentioned layered inorganic compound. In the case of 100 parts by mass of the above-mentioned radiation-curable adhesive, it is preferably adjusted so as to exceed the mass of the i-weight and 40 parts by mass or less. When the effect of the layered inorganic compound is more than 40 parts by mass, the viscosity of the coating liquid becomes too high, so that the smoothness of the surface of the antiglare film of the present invention cannot be obtained, and the optical properties are poor, or the coating liquid The viscosity is too high to be applied. The lower limit of the content of the above layered inorganic compound is 2 parts by mass, and the upper limit is more preferably 3 parts by mass. By setting it as the range, it is possible to more reliably obtain the preferable aggregation and inclination angle of the fine particles. The coating liquid can be prepared by mixing the above materials. The method of preparing the coating liquid by mixing the above materials is not particularly special. Qualified: If a paint shaker (paint sha) or a bead mill can be used as a diffusion layer, the coating liquid can be applied to the light-transmitting substrate to be dried to a surface h to form a coating. The film is cured and formed into a film, for example, a die coating method, etc. The coating method of the coating liquid is not particularly limited, and the roll coating method, the Meyer bar coating method, and the gravure coating method are not particularly limited. The thickness of the coating film formed by applying the coating liquid described above can be appropriately determined in consideration of the uneven shape formed on the surface, the material to be used, etc. It is preferable that the dry film thickness is about i 20 20 m or less. It is 2 to #爪. The reason is that if the film thickness is less than 1 A m, the hard coat property is poor, and if it exceeds 2 〇 "m, it is likely to cause curling or cracking. The thickness of the above diffusion layer can be made by the diffusion layer. The profile is measured by SEM observation or the like. The thickness of the surface of the diffusion layer from the absence of the organic fine particles (Μ) to the interface of the light-transmitting substrate is measured at five or more points, and the average value thereof is determined. Here, in the anti-glare film of the present invention, the diffusion layer is formed. In the above fine particles (A), the two aggregates are formed. When the coating liquid contains a layered inorganic compound, for example, the aggregate can be formed by the following method. First, according to the hydrophilicity of the fine particles (A) / The degree of hydrophobicity is determined in advance to determine the type and amount of the layered inorganic compound (for example, talc) suitable for agglomerating the two fine particles (A). Then, the determined layered inorganic compound is combined with the above fine particles (a) and the like. The coating film formed by using the coating liquid is mixed in the coating liquid, and the reason why the agglomerate is formed by such a method is not clear, but it is presumed that it is in the lower surface of the coating film. The light-transmitting substrate is affected by the difference in lipophilicity or surface tension of the air layer. Further, as described above, the organic fine particles (Β) having an impregnation layer are preferably prepared by swelling the above-mentioned organic fine particles (Β) by the above-mentioned radiation hardening type binder and/or solvent to impregnate the organic fine particles (Β). Radiation hard 32 201139140 Formulated adhesive and shaped 〇Λ The organic microparticles (B) of the α layer can be prepared in the above coating liquid, and can also be applied to the coating film formed on the above transparent substrate. In progress. The diffusion layer can be formed by hardening a coating film formed on the above-mentioned well-preserved substrate. The method of curing the coating film is not particularly limited, and it is preferably carried out by irradiation with ultraviolet rays. When curing by ultraviolet rays, it is preferred to use ultraviolet rays in a wavelength region of from 19 Å to 380 nm. The curing of the ultraviolet rays can be carried out, for example, by a metallized lamp, a high-pressure mercury lamp, a smudged mercury lamp, a super-high water money, a carbon fox lamp, a black fluorescent lamp, or the like. Specific examples of the electron beam source include a Cockcroft-Walton type, a Van core type "resonant transformer type, an insulating nuclear transformer type, a linear type, a high frequency high voltage (々(10) her type, a high frequency type, and the like). In the anti-glare film of the present invention, the diffusion layer has an uneven shape on the surface. The uneven shape of the surface of the diffusion layer is preferably at a position corresponding to the aggregate of the fine particles (A) in the diffusion layer. The convex portion (hereinafter also referred to as a convex portion (A)) is formed. The convex portion (A) formed on the surface of the diffusion layer is formed by the aggregated body, so that the particle diameter can be further improved, so that sufficient anti-glare can be exhibited. Performance, and because the particles are present obliquely, the area of the particles illuminated by the external light is smaller than that of the parallel side by side, and the reflection at the interface with the binder can be further reduced', so that the fading is preferably prevented. In addition, since it is not necessary to thicken the thickness of the diffusion layer, it is preferable to prevent the occurrence of cracking of the glare film of the present invention or the occurrence of cracking of the diffusion layer. When the dispersed layer contains the organic fine particles (B) having the above-mentioned impregnated layer, the height of the convex portion (hereinafter also referred to as a convex portion (B)) formed at a position corresponding to the organic fine particles (B) of the diffusion layer is low. The surface of the diffusion layer (C) of the organic fine particles (C) which completely satisfies the following requirements (丨), (2) and (3) and the convex portion at the position corresponding to the organic fine particles (c: Also referred to as the height of the convex portion (c). Necessary conditions (1, except that the organic fine particles (c) are used instead of the organic fine particles (B), a diffusion layer is formed under the same conditions as the diffusion layer containing the organic fine particles (B) ( c); Necessary condition (2): The organic fine particles (c) in the diffusion layer (c) have the same average particle diameter as the organic fine particles (B) in the diffusion layer; Necessary condition (3): Organic fine particles (c) The impregnation layer is not formed in the diffusion layer (c). The convex portion (B) of the diffusion layer corresponding to the organic fine particles (B) has a higher height and/or average inclination angle than the convex portion (C). Low, and gentle shape with diffusion to form such protrusions (8) The anti-glare film of the present invention is more excellent in anti-glare property and anti-fading property. [The reason is that the organic fine particles (B) in the diffusion layer are extremely more than the organic fine particles (C). Soft microparticles. That is, when the coating film is hardened right, the radiation-curing adhesive causes hardening and shrinkage, and the surface of the organic microparticle (B) is hardened and shrunk, and the surface of the organic microparticle (B) is absent. Compared with the hardening shrinkage, the above-mentioned radiation is more 5L | less sigma dose' is therefore smaller. However, since the above organic micro 34 201139140 = is very flexible microparticles, the above organic particles, B) will be The hardening of the coating film shrinks and deforms. As a result, it is estimated that the divergence and/or the average tilt angle of /(B) are compared with the above:: (c) formed on the surface of the diffusion layer (c) containing the harder organic fine particles (C). , lower and smoother. Furthermore, the height of the convex portion is observed by AFM as a convex portion by observing the difference between the height of the convex portion existing on the surface of the anti-glare film and the concave portion adjacent to the convex portion of the convex portion. Height η (n is 1~丨〇). The average value of the height of one of the convex portions obtained in this manner is averaged and obtained. The fine particles (A) in the diffusion layer of the anti-glare film of the present invention form two aggregates at a specific ratio, and the two fine particles (a) of the aggregate are connected to each other with respect to the surface of the light-transmitting substrate. Wait until the line of the towel ^ is inclined to form a sag. Therefore, the anti-glare film of the present invention can form a convex portion formed on the surface thereof at a position corresponding to the aggregate of the fine particles (A) to a southerly degree, and is excellent in anti-glare property, and can sufficiently suppress fading.

The tilt angle of the particle (Α) of the anti-glare film of the implementation order is 6〇~7〇. In the range of the scintillation, the evaluation of the flicker is poor, and the content of the layered inorganic compound of the antiglare film of Example 5 is less than that of the examples, etc., so that the hard coat property is poor, and the content of the layered inorganic compound of the antiglare film of Example 6 is contained. It is much larger than the example i, the viscosity of the coating liquid is high, and the surface smoothness of the anti-glare film is poor, so the evaluation of contrast, anti-glare property, and flicker is poor, but overall, it can be judged as a good result. On the other hand, the anti-glare film of the comparative example was not excellent in contrast, anti-glare property, and hard coat property. Further, the average particle size of the organic fine particles (Β) of the antiglare film of Reference Example 1 is equal to or greater than the thickness of the diffusion layer, and thus the contrast and the hard coat property are inferior.
