Hie又，也有蜮著在不含充填劑之情況下，於透明樹脂 層之表面上只有形成微細之凹凸而發現有防炫性。例如， 在曰本特開2002-189106號公報(專利文獻1)之請求專利範 圍第1至6項或段落〇〇43至0046中，係揭示在壓花鑄型 (emboss)與透明樹脂膜之間挾入有電離放射線硬化性樹脂 之狀態下，硬化該電離放射線硬化性樹脂，藉由形成使三 次元10點平均粗細度，及在三次元粗細度基準面上鄰接之 凸部相互間的平均距離，滿足各個所定值之微細凹凸，則 在透明樹脂膜上，可積層有該表面凹凸之電離放射線硬化❹ 性樹脂層的硬化物層而成的防炫膜。然而，使如此之以往 的防炫膜配置在晝像顯示裝置的表面時，則因散亂光導致 顯示面全部變成泛白，顯示變混濁色，而有容易發生白濁 現象之問題存在。 又，在尚精細化晝像顯示裝置之情形，晝像顯示裝置 之畫素（pixel)與防炫膜之表面凹凸形狀相互干擾，結果發 生亮度分佈而不容易看，即容易發生所謂的炫爍（glittering) 現象之問題。為了解決消除炫爍現象，雖曾有嘗試設定黏 ® 著劑樹脂與分散在其中之充填劑之間的折射率有差距，俾 使光散亂照射’但在高溫下使用如此之防炫膜時，因為黏 著劑樹脂及充填劑會變形或變質，導致防炫膜之表面形狀 也跟著變化’而會發生所謂的外光反映問題。又，即使在 使用初期沒有發生炫爍（glittering)之問題，但持續在高溫 下使用時’由於黏著劑樹脂與充填劑之間的折射率差會起 變化，黏著劑樹脂與充填劑之間的散亂減少，而有容易發 4 321551 201022712 生炫爍之問題。 【發明内容】 本發明係有鐘於相關現狀者提 異防炫性能，同時能^ w後I貞不有優 置高精細之書H 導辨視性下降，在配 "—象頋不裝置的表面時，不會發生炫 並且，即使在高溫下長時間使用其特性也不變化之耐ί性 優異之防贿，進—步，提供使用此防炫膜之防炫性偏光 板及晝像顯示震置。 依本發明之防炫膜，係具備有樹脂基材膜，與積層在 該樹知基材膜表面上，表面有微細之凹凸形狀之硬塗層的 防炫膜，該硬塗層係由分散有至少i種樹脂微粒子之透光 性樹知所組成，並且，該硬塗層之表面霧度(haze)是1%以 上10%以下，内部霧度是10%以上20%以下，於是，在硬 塗層含有之樹腊微粒子，係在23 °C中，浸潰於乙酸乙酯内 48小時時的體積變化率為10%以上’較佳是在50%以下之 樹脂微粒子。 在本發明之防炫膜中，透光性樹脂之折射率與樹脂微 粒子之折射率的差是以0.02以上0.06以下為佳。又，樹 脂微粒子之重量平均粒徑為2/zm以上loam以下，相對 於透光性樹脂100重量份’在硬塗層含有之樹脂微粒子以 在1重量份以上50重量份以下之範圍為佳。 本發明之防炫膜，亦可以在硬塗層之凹凸表面上，復 含有低反射膜。 又依本發明，可以提供一種防炫性偏光板，其係由上 321551 5 201022712 述任何記載之防炫膜與偏光膜貼合而成之防炫性偏光板， 該偏光膜為配置在防炫膜之樹脂基材膜側。 本發明之防炫膜或防炫性偏光板，係與液晶顯示元件 或電漿顯示板等之晝像顯示元件組合，可以作成晝像顯示 裝置。即，依本發明可以提供，具有上述任何記載之防炫 膜或上述防炫性偏光板，與晝像顯示元件，防炫膜或防炫 性偏光板，為將其硬塗層側當作外側而配置在晝像顯示元 件之辨視側之晝像顯示裝置。 本發明之防炫膜，係顯示有優異防炫性能，同時能防 止因白濁導致之辨視性下降，又，在配置高精細之畫像顯 示裝置的表面時，沒有發生炫爍現象，並且，耐久性優異 之防炫膜。將本發明之防炫膜與與偏光膜組合之防炫性偏 光板，發現有同樣之效果。因此，配置本發明之防炫膜或 防炫性偏光板之晝像顯示裝置，係防炫性能高，辨視性及 耐久性優異者。 【實施方式】 實施發明之最佳形態： <防炫膜> 第1圖，係顯示本發明好的防炫膜之一個例子的截面 模式圖。在第1圖顯示之防炫膜，係具備有樹脂基材膜1， 與積層在樹脂基材膜1之表面上，表面有微細之凹凸形狀 之硬塗層的硬塗層2。硬塗層2，係在黏著劑樹脂之透光性 樹脂中分散有樹脂微粒子3。以下，更詳細說明本發明之 防炫膜。 6 321551 201022712 (樹脂基材膜） 作為樹脂基材膜者，只要是實質上有光學透明性之膜 即可’而無特別限制，可以使用各種之透明樹脂膜。具體 上’除了由二乙酸纖維素、二乙酸纖維素、丙酸乙酸纖維 素曰·#纖維素系樹脂等之外，可列舉如：由環烯煙系樹脂、 t碳酸s曰、聚甲基丙烯酸甲酯、聚颯、聚醚颯、聚氣乙烯、 聚對苯二曱酸二乙酯等所構成之薄膜等。環烯烴系樹脂係 將降水片婦、二亞甲基八氫萘等環狀烯烴當作單體之樹 ®脂’具體上之市售品可列舉如：「ARTON」（JSR(股）製）、 ZE〇N〇R」（日本ΖΕΟΝ(股）製）、「ZEONEX」（日本 ΖΕΟΝ(股)製）等。 樹化基材膜之厚度以在以上250/zm以下為 佳，更佳是在40_以上17〇，以下。樹脂基材膜 度較薄時’很難得到作為防炫膜之充分硬度。又 材膜之厚度較厚時，從最近之對畫像顯示裝置的薄型^ ❹要求=成本等觀點而言並不適合。從防炫膜全體 做成薄的觀點而言，樹脂基材膜之厚度是以做成又要 以下為佳，進-步做成12认鱗崎惠秦' — Um (硬ί層） 具備本發明之防炫膜，在表面有微 層，係在上述樹脂基材絲面上積層者，由分 種透光性之樹賴粒子的透紐樹脂(硬輯脂二有 在本發明中「透光性」係指不管物質内部是否有》f1 而光幾乎都可以透過之意思。 ‘，，、散亂， 321551 7 201022712 本發明中，硬塗層之表面霧度是做成1%以上1〇%以 下，内部霧度是做成1〇 〇/。以上20%以下。在此，硬塗層之 表面霧度及内部霧度係以如下方式測定。即，首先，在霧 度幾乎為0%之三乙酸纖維素膜上形成該硬塗層之後，以 二乙酸纖維素膜側作為接合面之方式，將該積層膜與玻璃 基板，利用透明黏著劑貼合，根據JISK7138測定霧度。 該霧度是相當於硬塗層全體之霧度。其次，在硬塗層之凹 凸表面使用甘油貼合霧度幾乎為0%之三乙酸纖維素膜， 再度根據JIS K 7138測定霧度。因為表面凹凸引起之表面 務度為幾乎由在表面凹凸上貼合之三乙酸纖維素膜抵消， 故该霧度可以看作硬塗層之「内部霧度」。於是，硬塗層之 「表面霧度」可以由下述式（1)求得。 表面霧度=整體之霧度—内部霧度 藉由使硬塗層之表面霧度定為1〇%以下，可以有效地 抑制在畫像顯示裝置中使用防炫膜之時的白濁現象。為了 更有效抑制白濁’硬塗層之表面霧度以在5%以下為佳。 只是，降到1%以下時因為顯示不出充分之防炫性，故硬 塗層之表面霧度以定在1%以上為佳。 又，藉由使硬塗層之内部霧度做成1〇%以上，可以有 消除畫像顯示裝置中使用防炫膜時之炫燦效果。為了更有 效消除炫爍現象，硬塗層之内部霧度是以15%以上為佳。 又，藉由使硬塗層之内部霧度做成2〇%以下，在晝像顯_ 裝置中使用防賴時，可㈣止畫像變黑，辨錄受損= 情形。 ' . 321551 8 201022712 本發明中’滿足上述光學特性之賦予表面凹凸之硬塗 層，係使用至少有1種透光性之樹脂微粒子及透光性樹脂 而化成。更具體而言，如此之硬塗層，例如，在樹脂基材 膜上塗布分散有以透光性樹脂微粒子作為填充劑之透光性 樹脂溶液，調整塗布膜厚度，可以形成透光性樹脂微粒子 之部份成為凸狀。又將分散有以透光性樹脂微粒子作為填 充劑之透光性樹脂溶液在樹脂基材膜上塗布，並藉由上述 專利文獻1揭示之壓花法也可以形成表面凹凸。 €> 在此，在本發明之防炫膜中所使用之透光性樹脂微粒 子，係在醋酸乙酯中浸潰48小時時的體積變化率在1 〇0/〇 以上。藉由使用在醋酸乙酯中浸潰48小時時的體積變化率 在10%以上之樹脂微粒子，在高溫下使用之特性（尤其霧度 特性）變化小’可能得到耐久性優之防炫膜。 依據本發明人等之檢討結果，將具備有分散樹脂微粒 子之硬塗層的防炫膜曝露在高溫下時，構成透光性樹脂及 ❹樹脂微粒子之樹脂，係分別進行交聯反應，其結果，透光 性樹脂及樹脂微粒子之折射率，係分別提昇。此時，通常， 構成透光性樹脂之樹脂’因為比樹脂微、.粒應度低（交 和氆度低），所以經由高溫曝露而交聯反應之進行情形，透 光性樹脂比樹脂微粒子還大，折射率提昇變得更大。如此， 使防炫膜在高溫下曝露時，因為其霧度特性（尤其内部霧度) 會變化，故伴隨透光性樹脂有較大之折射率提昇，判定導 致透光性樹脂與樹脂微粒子之折射率比（或是折射率差）會 偏離當初所設定之值的一個原因。 321551 9 201022712 依據本發明，使用在醋酸乙酯中浸潰48小時的體積 變化率在10%以上之樹脂微粒子時，如此之樹脂微粒子， 由於比以往使用之樹脂微粒子有更低之交聯密度（反應度 低），使所得防炫膜在高溫曝露時之交聯反應的進行情形， 於是折射率上昇變得更大。藉由此，使防炫膜在高溫曝露 時之透光性樹脂與樹脂微粒子的折射率比（或是折射率差） 之變化，與以往使用樹脂微粒子之情形相比因為較低，尤 其因高溫曝露可以降低内部霧度之變化。 在本發明之防炫膜中使用之透光性樹脂微粒子之，在 © 醋酸乙酯中浸潰48小時時的體積變化率之下限，從耐久性 (尤其内部霧度之降低）方面而言，係無特別限定，但從分 散樹脂微粒子之透光性樹脂溶液的安定性觀點而言，以在 50 %以下為佳，以在30 %以下較佳，以在20 %以下更佳。 本發明中，樹脂微粒子之，在醋酸乙酯中浸潰48小 時時的體積變化率係以如次測定。即，首先，測定在醋酸 乙酯中浸潰前的樹脂微粒子之平均粒徑d〇。平均粒徑d〇 ❹ 係以顯微鏡觀察在醋酸乙酯中浸潰前的樹脂微粒子，在此 視野内任意選擇20個之樹脂微粒子藉由晝像解析而求得 該20個樹脂微粒子之平均粒徑。其次，使樹脂微粒子在醋 酸乙酯内，23°C中浸潰48小時時，將浸潰後的樹脂微粒子 之平均粒徑d48以同樣之晝像解析而求得。使用此等之平 均粒徑，依以下之式（2)求得體積變化率（％)。 體積變化率(％)=d483/d〇3 X 100— 100 (2) 構成在硬塗層中分散之透光性樹脂微粒子的樹脂種 10 321551 201022712 類’係只要調整使硬塗層之光學特性（尤其内部霧度）在上 述範圍内而得者，並且，在醋酸乙酯中浸潰48小時時的體 積變化率在上述範圍内者即可而無特別限定，例如列舉， 三聚氰胺小球（折射率：1·57)、聚甲基丙烯酸甲酯小球（折 射率：1.49)、甲基丙烯酸甲酯/苯乙烯共聚物樹脂小球(折 射率：1.50至1.59)、聚碳酸酯小球(折射率：1.55)、聚乙 烯小球(折射率：1.53)、聚苯乙烯小球(折射率：1.6)、聚氯 化乙烯小球(折射率：1.46)、矽氧樹脂小球(折射率：1.46) ❹等。 本發明中使用之樹脂微粒子，因為硬塗層之内部霧度 做成10 %以上20%以下，故以選擇使樹脂微粒子之折射率 與成為硬塗層基材的透光性樹脂（硬塗樹脂）之折射率的差 能成為0.0 2以上〇 · 〇 6以下之樹脂微粒子為佳。 又，在本發明中使用之樹脂微粒子，其重量平均粒徑 以在2弘m以上10 #

For example, in the patent claims 1 to 6 or paragraphs 至43 to 0046 of the Japanese Patent Publication No. 2002-189106 (Patent Document 1), it is disclosed in the embossing and transparent resin film. In the state in which the ionizing radiation curable resin is interposed, the ionizing radiation curable resin is cured, and the average thickness of the three-dimensional 10 points and the average of the convex portions adjacent to each other on the third-order thickness reference surface are formed. In the transparent resin film, an anti-foaming film obtained by laminating a cured layer of an ionizing radiation-curable resin layer on the surface of the transparent resin film can be laminated. However, when such a conventional anti-glare film is disposed on the surface of the image display device, the display surface is completely whitened by the scattered light, and the display becomes cloudy, and there is a problem that white turbidity is likely to occur. Moreover, in the case where the image display device is still refined, the pixel of the image display device and the surface unevenness of the anti-glare film interfere with each other, and as a result, the brightness distribution is not easy to see, that is, the so-called swaying is likely to occur. (glittering) The problem of phenomena. In order to solve the problem of eliminating the squeaking phenomenon, there has been an attempt to set a gap between the refractive index of the adhesive resin and the filler dispersed therein, so that the light is scattered and irradiated, but when such an anti-glare film is used at a high temperature. Because the adhesive resin and the filler may be deformed or deteriorated, the surface shape of the anti-foam film may also change, and a so-called external light reflection problem may occur. Moreover, even if there is no problem of glittering at the initial stage of use, when it is continuously used at a high temperature, 'the refractive index difference between the adhesive resin and the filler changes, and between the adhesive resin and the filler. The scattered is reduced, and there is a problem that it is easy to send 4 321551 201022712. SUMMARY OF THE INVENTION The present invention is related to the current situation of the presenter to improve the anti-glare performance, and at the same time, I can not have a high-precision book, and the visibility of the book is lowered, and the device is not equipped. When the surface is not smashed, and even if it is used for a long time at a high temperature, it is excellent in the resistance to bribery, and the anti-glare polarizing plate and the image using the anti-glare film are provided. The display is shaken. The anti-foaming film according to the present invention is provided with a resin base film and an anti-foam film which is laminated on the surface of the substrate to have a fine uneven shape on the surface of the substrate film, and the hard coat layer is dispersed. It has a light transmittance of at least one kind of resin fine particles, and the surface haze of the hard coat layer is 1% or more and 10% or less, and the internal haze is 10% or more and 20% or less. The fine particles of the waxy layer contained in the hard coat layer are at a temperature of 23 ° C, and the volume change rate when the resin is immersed in ethyl acetate for 48 hours is 10% or more, preferably 50% or less. In the antiglare film of the present invention, the difference between the refractive index of the translucent resin and the refractive index of the resin microparticles is preferably 0.02 or more and 0.06 or less. Further, the weight average particle diameter of the resin fine particles is 2/zm or more and less than or equal to or less than 100 parts by weight of the resin fine particles contained in the hard coat layer in the range of 1 part by weight or more and 50 parts by weight or less. The anti-glare film of the present invention may further comprise a low-reflection film on the uneven surface of the hard coat layer. According to the present invention, it is possible to provide an anti-glare polarizing plate which is an anti-glare polarizing plate which is formed by attaching an anti-glare film and a polarizing film described in any of the above-mentioned 321551 5 201022712, and the polarizing film is disposed in the anti-glare layer. The resin substrate side of the film is on the film side. The anti-glare film or the anti-glare polarizing plate of the present invention can be combined with an image display element such as a liquid crystal display element or a plasma display panel to form an image display device. That is, according to the present invention, it is possible to provide the anti-foam film or the anti-glare polarizing plate of any of the above, and the image display element, the anti-glare film or the anti-glare polarizing plate, in which the hard coat side is regarded as the outer side. The image display device is disposed on the viewing side of the image display element. The anti-glare film of the present invention exhibits excellent anti-glare properties, and at the same time prevents deterioration of visibility due to white turbidity, and does not cause squeaking when the surface of the high-definition image display device is disposed, and is durable. Excellent anti-glare film. The anti-glare film of the present invention and the anti-glare polarizing plate combined with the polarizing film were found to have the same effects. Therefore, the image display device in which the anti-glare film or the anti-glare polarizing plate of the present invention is disposed is excellent in anti-glare property, excellent in visibility and durability. [Embodiment] The best mode for carrying out the invention: <Anti-glare film> Fig. 1 is a cross-sectional schematic view showing an example of a good anti-foam film of the present invention. The anti-foam film shown in Fig. 1 is provided with a resin substrate film 1 and a hard coat layer 2 which is laminated on the surface of the resin substrate film 1 and has a fine uneven coating on the surface. The hard coat layer 2 is obtained by dispersing resin fine particles 3 in a light-transmitting resin of an adhesive resin. Hereinafter, the antiglare film of the present invention will be described in more detail. 6 321551 201022712 (Resin base material film) The resin base film is not particularly limited as long as it is a film having substantially optical transparency, and various transparent resin films can be used. Specifically, 'in addition to cellulose diacetate, cellulose diacetate, cellulose acetate propionate 纤维素·# cellulose resin, etc., examples thereof include a cycloolefin resin, a t-carbonate, and a polymethyl group. A film composed of methyl acrylate, polyfluorene, polyether fluorene, polyethylene gas, polyethylene terephthalate or the like. The cycloolefin-based resin is a commercially available product of a cyclic olefin such as a precipitated tablet or a dimethyl octahydronaphthalene as a monomeric product. For example, "ARTON" (manufactured by JSR) , ZE〇N〇R" (Japanese ΖΕΟΝ (share) system), "ZEONEX" (Japanese ΖΕΟΝ (share) system). The thickness of the dendified base film is preferably 250 or more and more, more preferably 40 or more and 17 or less. When the resin substrate has a small film thickness, it is difficult to obtain sufficient hardness as an anti-foam film. Further, when the thickness of the film is thick, it is not suitable from the viewpoint of the thinness of the image display device recently, the cost, and the like. From the viewpoint of making the entire anti-glare film thin, the thickness of the resin substrate film is preferably made to be the following, and the 12-step scales are made into a step-by-step U-Qi-Qi-Um (hard layer) The anti-glare film of the invention has a microlayer on the surface, and is laminated on the surface of the resin substrate, and the resin is made of a kind of light-transmitting tree-based resin. "Light" means that light is almost transparent even if there is "f1" inside the material. ',,, scatter, 321551 7 201022712 In the present invention, the surface haze of the hard coat layer is made 1% or more. The internal haze is 1 Å or more and 20% or less. Here, the surface haze and the internal haze of the hard coat layer are measured as follows. First, the haze is almost 0%. After the hard coat layer was formed on the cellulose triacetate film, the laminated film and the glass substrate were bonded together with a transparent adhesive so that the cellulose acetate film side was used as a bonding surface, and the haze was measured in accordance with JIS K7138. The degree is equivalent to the haze of the entire hard coat layer. Secondly, the use of the hard surface of the hard coat is used. The oil was attached to a cellulose triacetate film having a haze of almost 0%, and the haze was measured again in accordance with JIS K 7138. Since the surface roughness caused by the surface unevenness was almost offset by the cellulose triacetate film attached to the surface unevenness, Therefore, the haze can be regarded as the "internal haze" of the hard coat layer. Thus, the "surface haze" of the hard coat layer can be obtained by the following formula (1): Surface haze = overall haze - internal mist By setting the surface haze of the hard coat layer to 1% or less, it is possible to effectively suppress the white turbidity phenomenon when the anti-foam film is used in the image display device. In order to more effectively suppress the surface haze of the white turbid 'hard coat layer It is preferably 5% or less. However, when it is less than 1%, since the sufficient anti-glare property is not exhibited, the surface haze of the hard coat layer is preferably set to be 1% or more. The internal haze of the layer is made 1% or more, which can eliminate the dazzling effect when the anti-glare film is used in the image display device. In order to more effectively eliminate the squeaking phenomenon, the internal haze of the hard coat layer is 15% or more. Further, by making the internal haze of the hard coat layer 2% or less, in the image _ When the device is used for tampering, the image may be blackened and the image may be damaged. [ 321551 8 201022712 In the present invention, at least one type of hard coat layer which satisfies the above optical characteristics and imparts unevenness on the surface is used. The light-transmitting resin fine particles and the light-transmitting resin are formed. More specifically, such a hard coat layer is coated with a light-transmitting resin in which a light-transmitting resin fine particle is used as a filler, for example, on a resin base film. In the solution, the thickness of the coating film is adjusted to form a portion in which the light-transmitting resin fine particles are formed into a convex shape, and the light-transmitting resin solution in which the light-transmitting resin fine particles are used as a filler is applied onto the resin substrate film, and The embossing method disclosed in the above Patent Document 1 can also form surface irregularities. Here, the light-transmitting resin fine particles used in the anti-glare film of the present invention are impregnated in ethyl acetate for 48 hours. The volume change rate is above 1 〇0/〇. By using resin fine particles having a volume change rate of 10% or more when immersed in ethyl acetate for 48 hours, the characteristics (especially haze characteristics) used at a high temperature are small, and an anti-foam film having excellent durability can be obtained. According to the results of the review by the present inventors, when the anti-foam film having the hard coat layer of the dispersed resin fine particles is exposed to a high temperature, the resin constituting the light-transmitting resin and the resin fine particles is subjected to a crosslinking reaction. The refractive indices of the light-transmitting resin and the resin fine particles are respectively increased. In this case, in general, the resin constituting the light-transmitting resin is lower in viscosity than the resin (the degree of cross-linking is lower), so that the cross-linking reaction proceeds through high-temperature exposure, and the light-transmitting resin is more than the resin fine particles. Still larger, the refractive index increase becomes larger. When the antifoam film is exposed to a high temperature, the haze property (especially the internal haze) changes, so that the translucent resin has a large refractive index increase, and it is judged that the translucent resin and the resin microparticles are caused. The reason why the refractive index ratio (or the refractive index difference) deviates from the value set at the beginning. 321551 9 201022712 According to the present invention, when resin fine particles having a volume change rate of 10% or more are immersed in ethyl acetate for 48 hours, such resin fine particles have a lower crosslink density than resin fine particles used in the past ( The degree of reaction is low, and the crosslinking reaction of the obtained anti-foam film at the time of high-temperature exposure proceeds, and thus the refractive index rise becomes larger. Therefore, the change in the refractive index ratio (or the refractive index difference) of the light-transmitting resin and the resin fine particles when the anti-foam film is exposed to high temperature is lower than that in the case of using the resin fine particles in the past, especially due to the high temperature. Exposure can reduce the change in internal haze. The lower limit of the volume change rate when the light-transmitting resin fine particles used in the anti-glare film of the present invention are immersed in ethyl acetate for 48 hours, in terms of durability (especially, reduction in internal haze), It is not particularly limited, but is preferably 50% or less, more preferably 30% or less, and even more preferably 20% or less from the viewpoint of stability of the light-transmitting resin solution for dispersing the fine resin particles. In the present invention, the volume change rate of the resin fine particles when immersed in ethyl acetate for 48 hours is measured as follows. Namely, first, the average particle diameter d〇 of the resin fine particles before being impregnated in ethyl acetate was measured. The average particle diameter d〇❹ is a microscopic observation of resin fine particles before impregnation in ethyl acetate, and 20 resin fine particles are arbitrarily selected in this field of view. The average particle diameter of the 20 resin fine particles is determined by image analysis. . Next, when the resin fine particles were immersed in ethyl acetate at 23 ° C for 48 hours, the average particle diameter d48 of the impregnated resin fine particles was determined by the same image analysis. Using these average particle diameters, the volume change rate (%) was obtained by the following formula (2). Volume change rate (%) = d483 / d 〇 3 X 100 - 100 (2) Resin type constituting the light-transmitting resin fine particles dispersed in the hard coat layer 10 321551 201022712 Class 'systems only need to adjust the optical properties of the hard coat layer (In particular, the internal haze is obtained within the above range, and the volume change rate when immersed in ethyl acetate for 48 hours is not particularly limited, and for example, melamine beads (refraction) Rate: 1.57), polymethyl methacrylate pellet (refractive index: 1.49), methyl methacrylate/styrene copolymer resin pellet (refractive index: 1.50 to 1.59), polycarbonate pellet ( Refractive index: 1.55), polyethylene pellet (refractive index: 1.53), polystyrene pellet (refractive index: 1.6), polyvinyl chloride pellet (refractive index: 1.46), oxime resin pellet (refractive index : 1.46) ❹ and so on. In the resin fine particles used in the present invention, since the internal haze of the hard coat layer is 10% or more and 20% or less, the refractive index of the resin fine particles and the light-transmitting resin which becomes a hard coat substrate (hard coating resin) are selected. The difference in refractive index of the film is preferably 0.02 or more and ≤ 6 or less of the resin fine particles. Further, the resin fine particles used in the present invention preferably have a weight average particle diameter of 2 m or more and 10 # m or less, more preferably 4 # m or more and 8 # m or less. When the weight average particle diameter is small, it becomes impossible to have sufficient anti-glare property, or there is a tendency to increase the internal haze. When the weight average particle diameter is large, the surface haze becomes large. As a result, the anti-foam film is cloudy and lowered. Discrimination, there is a tendency to not obtain sufficient internal haze. Here, the "weight average particle diameter" is a weight average particle diameter measured by the Coulter method. The weight average particle size using the Coulter method can be measured, for example, using "Coulter Multisizer 3" (manufactured by Beckman Coulter Co., Ltd.) of a precise particle size distribution measuring apparatus. Further, the resin fine particles contained in the hard coat layer are preferably in the range of from 1 part by weight to 50 parts by weight, based on 100 parts by weight of the light-transmitting resin, 11 321551 201022712. It is more preferably in the range of 40 parts by weight or less based on 100 parts by weight of the light-transmitting tree. When the content of the resin fine particles is small, it is not sufficient to show sufficient anti-glare property, and the surface unevenness is sparse, so that the inner haze tends to be small under the texture. Further, the content of the resin fine particles is large, and the fog of the temple becomes A. The result is an anti-glare film or a white turbidity, or a tendency to decrease in contrast and decrease in visibility. As a light-transmitting resin of the Kawasaki resin fine particles, an ultraviolet curable resin, a thermosetting resin, an electron curable resin, or the like can be used, and an ultraviolet curable resin is used from the viewpoint of k production|±10 degrees. It is better. As the ultraviolet curable resin, a commercially available product can be used. E.g,

After the fine particles are applied to the resin substrate film and dried, the resin particles are dispersed in the light-transmitting resin (hard coating resin) by irradiation with ultraviolet rays to form a hard coat layer. When the hard coat layer is formed into a fine uneven shape, as disclosed in Patent Document 1 and the like, a mold having a fine uneven shape is used, and the shape of the mold is transferred to a light-transmitting resin film (that is, a light-transmitting grease). It is possible to apply a resin film to the resin film. The transfer of the mold shape to the enamel film is preferably performed by embossing, and as an embossing, uv embossing using an ultraviolet curable resin. Law 321551 12 201022712 The uv embossing method is an ultraviolet curable resin layer (a resin composition layer composed of a translucent resin and resin fine particles) formed on the surface of a resin substrate film, and the external curable resin layer is formed. When the surface of the mold is pressed and hardened, the uneven surface of the mold can be transferred onto the ultraviolet curable resin film. Specifically, the ultraviolet ray having dispersed the light-transmitting resin particles is applied onto the resin substrate film. In the curable resin, the ultraviolet curable resin layer to be applied is adhered to the uneven surface of the mold, and the ultraviolet curable resin layer is cured by irradiating ultraviolet rays from the resin substrate film side, and then peeled off from the mold. The resin base film formed of the ultraviolet curable resin layer after the curing is transferred to the ultraviolet curable resin layer, and the ultraviolet light is cured. The type of the raw material is not particularly limited. Further, instead of the ultraviolet curable tree, A visible light curable resin which may be hardened by visible light having a long ultraviolet wavelength may be used as long as the photoinitiator is appropriately selected. When the surface of the hard coat layer is not embossed by the embossing method, the thickness of the hard coat layer is obtained by adjusting the surface haze to the above range, but it is 2/m or more. 〇#m below is not good when the thickness of the hard coating is insufficient, there is not enough hardness, and there is a tendency to be damaged. When it is thicker, it is easy to break, or due to the shrinkage of the hard coating, it is anti-glare. The film is warped and the productivity is lowered. Further, the thickness of the hard layer is generally 85% or more with respect to the weight average particle diameter of the dispersed light-transmitting resin fine particles, and more preferably 1〇〇% or more. ^The thickness of the coating is smaller than the weight average particle diameter of the resin microparticles, and the surface haze will increase. As a result, the antifoam film tends to be cloudy and the visibility is lowered. 321551 13 201022712 In the embossing method, when the surface of the hard coat layer is formed into a concave-convex shape, the thickness of the hard layer is preferably 2/zm or more and 20/zm or less. When the thickness of the hard coat layer is less than 2 μm, sufficient hardness is not obtained, and there is a tendency to be easily damaged. When it is thicker than 20/im, it is easily broken, or the anti-foam film is warped due to hardening and shrinkage of the hard coat layer. The tendency to reduce productivity. The thickness of the hard coat layer is generally preferably 100% or more, more preferably 120% or more, based on the weight average particle diameter of the dispersed light-transmitting resin fine particles. When the thickness of the hard coat layer is thinner than the weight average particle diameter of the resin fine particles, there is a case where the resin fine particles have an unexpected influence on the surface uneven shape of the hard coat layer, and the desired surface haze value of the crucible is not obtained. The anti-glare film of the present invention may have a low-reflection film on its outermost surface, i.e., on the four convex side of the hard coat layer. In the absence of a low-reflection film, it is possible to perform a sufficient function, and by providing a low-reflection film on the outermost surface, the anti-glare property can be further improved. The low reflection film can be formed on the hard coat layer by providing a layer of a low refractive index material having a lower refractive index. Specific examples of such a low refractive index material include inorganic materials such as lithium fluoride (LiF), magnesium fluoride (MgF2), aluminum fluoride (AIF3), and crystal stone (3NaF·AIF3 or Na3A1F6). w Microparticles: Inorganic low-reflection materials contained in acrylic resins or epoxy tree rafts; organic low-temperature organic compounds, thermoplastic resins, thermosetting resins, UV curable resins, etc. Reflective material. <Anti-glare polarizing plate> The anti-glare film of the present invention is excellent in anti-glare effect, effective in preventing white turbidity, can effectively suppress the occurrence of squeaking, and is excellent in durability, and is used in an image display device. The glazed film can be used to obtain the image display device with excellent visibility and durability 321551 14 201022712. The image display device is liquid. This anti-glare film is applied to the polarizing plate. That is, the state %, may be: or, the alignment of the polyglycolic alcohol-based resin film 1 of the color dye is at least on the early surface of the shape of the protective film (four), but this is the same as Anti-glare film to form. The polarizing film and the anti-glare film of the present invention are used as a resin substrate for the anti-foam film, and a x 10 polarizing plate.

如表1及表2所示，本發明之防炫膜（實施例1至3) 及比較例1之防炫膜任何一種在80°C乾燥200小時之前， 23 321551 201022712 不僅顯示有優異之防炫性能，同時也不發生炫爍或白濁， 顯示為有良好之光學特性。然而’，比較例1之防炫膜，在 23°C中浸潰於乙酸乙酯48小時時之體積變化率幾乎為0% 的樹脂微粒子在硬塗層中使用，在80°C乾燥200小時，會 造成硬塗層之内部霧度大幅下降，結果會發生炫爍。 另一方面，本發明之防炫膜（實施例1至3)，藉由在 80°C乾燥200小時，硬塗層之表面及内部霧度等之光學特 性的劣化，與比較例1的相比時也有效地被抑制，有優異 之耐久性。又，内部霧度之降低抑制效果，隨使用之樹脂 微粒子之體積變化率愈大，則有愈大之傾向。但是，實施 例3之防炫膜中，在80°C乾燥200小時前之内部霧度為 10.8 %因為比較低，故因乾燥之内部霧度降低極為小，導 致在80°C乾燥200小時後產生炫爍之結果。實施例3之防 炫膜中，在80°C乾燥200小時前之内部霧度比較低，係認 為因樹脂微粒子之體積變化率高到63%導致塗布液C之安 定性下降。如此，從硬塗層之内部霧度的下降抑制觀點而 言，使用之樹脂微粒子的體積變化率以大者較佳，考慮到 初期狀態（高溫曝露前）之内部霧度時，樹脂微粒子之體積 變化率是以50 %左右以下為佳。 認為不受到此次揭示之實施形態及實施例全部之例 示限制，本發明之範圍不僅例示上述說明之專利申請範 圍，也包含與專利申請範圍均等意義及範圍内之全部變更。 [產業上之可能利用性]As shown in Tables 1 and 2, any of the anti-foam films of the present invention (Examples 1 to 3) and the anti-foam film of Comparative Example 1 were dried at 80 ° C for 200 hours, and 23 321551 201022712 not only showed excellent resistance. Hyun performance, while no glare or white turbidity, showing good optical properties. However, in the anti-glare film of Comparative Example 1, resin fine particles having a volume change rate of almost 0% when immersed in ethyl acetate for 48 hours at 23 ° C were used in a hard coat layer, and dried at 80 ° C for 200 hours. , the internal haze of the hard coating layer will be greatly reduced, and the result will be dazzling. On the other hand, the anti-foam film of the present invention (Examples 1 to 3) was deteriorated in optical properties such as surface and internal haze of the hard coat layer by drying at 80 ° C for 200 hours, and the phase of Comparative Example 1 It is also effectively suppressed in comparison with time and has excellent durability. Further, the effect of suppressing the reduction of the internal haze tends to be larger as the volume change rate of the resin fine particles used is larger. However, in the anti-glare film of Example 3, the internal haze before drying at 80 ° C for 200 hours was 10.8% because it was relatively low, so the internal haze reduction due to drying was extremely small, resulting in drying at 80 ° C for 200 hours. Produce the result of dazzling. In the anti-foam film of Example 3, the internal haze before drying at 80 ° C for 200 hours was relatively low, and it was considered that the stability of the coating liquid C was lowered due to the volume change rate of the resin fine particles being as high as 63%. Thus, from the viewpoint of suppressing the decrease in the internal haze of the hard coat layer, the volume change ratio of the resin fine particles used is preferably larger, and the volume of the resin fine particles is considered in consideration of the internal haze in the initial state (before high temperature exposure). The rate of change is preferably around 50%. The scope of the present invention is intended to be limited only by the scope of the invention and the scope of the invention. [Industry possible use]
