201002768 六、發明說明： 【發明所屬之技術領域】 本發明係有關適合作爲攜帶型資訊終端之顯示窗保護 板的耐擦傷性樹脂板及使用其之攜帶型資訊終端之顯示窗 保護板。 【先前技術】 近年來，行動電話或 PHS ( Personal Handy-phone System )(個人電話系統））等的攜帶型電話類，在隨著 網際網路（internet )的普及，同時除了單純的語音傳達 功能外，尙具有顯示文字資訊或影像資訊之功能的攜帶型 資訊終端已廣泛普及。另外，與此種攜帶型電話類不同， 除了住址名簿等的功能外，兼具網際網路功能或電子郵件 功能的 PDA( Personal Digital Assistant，個人數位助理 ))也被廣泛使用。 此等攜帶型資訊終端係藉由液晶或EL (電致發光） 等的方式，顯示文字資訊或影像資訊，但是其顯示窗中， 作爲保護板一般採用透明樹脂製者（參照例如日本特開 2002-6764號公報、特開2004-143365號公報、特開2004-2 99 1 99號公報）。而且爲了防止此保護板之表面刮傷，提 案設置藉由硬化性塗料而具有耐擦傷性（硬化性）的硬化 被膜。 此外，隨著攜帶型資訊終端之薄型化，因而對於顯示 窗保護板要求薄型化。 -5- 201002768 但是顯示窗保護板進行薄型化時’容易變軟’更容易 與液晶面（即内部之液晶構件的偏光板）接觸。顯示窗保 護板與偏光板接觸時，會產生稱爲牛頓環之光的干涉圖案 ，且不會消失，因此有影像品質降低的問題。 【發明內容】 〔發明之揭示〕 本發明之課題係提供一種在樹脂基板之一面形成可抑 制影像品質降低之硬化被膜的耐擦傷性樹脂板、及使用其 之攜帶型資訊終端之顯示窗保護板。 本發明人等爲了解決上述課題精心硏究的結果’發現 由以下構成所構成的解決手段，遂完成本發明。 (1) 一種耐擦傷性樹脂板，其特徵係在樹脂基板之一面 形成相對於前述樹脂基板之靜摩擦係數爲未達〇·4的硬化 被膜，且另一面形成相對於前述樹脂基板之靜摩擦係數爲 0.4以上之硬化被膜所成。 (2 )如前述（1 )項之耐擦傷性樹脂板，其中前述靜摩擦 係數爲0.4以上的硬化被膜具有109〜1〇14Ω/□的表面電阻 率。 (3 )如前述第（1 )或（2 )項之耐擦傷性樹脂板，其中 前述樹脂基板之厚度爲0.3〜1.5mm。 (4 )如前述（1 ) ~ ( 3 )項中任一項之耐擦傷性樹脂板， 其中前述樹脂基板爲丙烯酸系樹脂板。 (5 )如前述（1 )〜（3 )項中任一項之耐擦傷性樹脂板， -6- 201002768 其中前述樹脂基板爲在聚碳酸酯樹脂層之至少一面被層合 甲基丙烯酸樹脂層所成的層合板。 (6 )如前述（1 )〜（5 )項中任一項之耐擦傷性樹脂板， 其中前述樹脂基板含有橡膠粒子。 (7 ) —種攜帶型資訊終端之顯示窗保護板，其特徵係由 前述（1 ) ~ ( 6 )項中任一項之耐擦傷性樹脂板所構成。 (8 )如前述（7 )項之攜帶型資訊終端之顯示窗保護板， 其中形成前述靜摩擦係數未達0.4之硬化被膜的面朝液晶 面側設置。 本發明之前述「攜帶型資訊終端」係指人能攜帶程度 的大小，具有能顯示文字資訊或影像資訊等用之窗（ d i s p 1 a y )者的總稱，例如有前述例示之行動電話或P H S、 PDA 等。 依據本發明時，在樹脂基板之一面形成相對於前述樹 脂基板之靜摩擦係數爲未達0.4的硬化被膜，因此該硬化 被膜接觸液晶構件之偏光板，即使產生牛頓環，該硬化被 膜在偏光板上藉由滑動，而離開偏光板，故牛頓環容易消 失。因此依據本發明時，即使產生牛頓環，也可使其即刻 消失，具有抑制影像品質降低的效果。而且，在另一面形 成所定之硬化被膜，因此，此耐擦傷性樹脂板作爲攜帶型 資訊終端之顯示窗保護板使用，可有效保護該顯示窗。 特別是如前述（2 )，前述靜摩擦係數爲0.4以上的 硬化被膜具有1〇9〜1〇14 Ω/□的表面電阻率時’可抑制塵埃 附著於該硬化被膜。 201002768 將本發明使用於如前述（3 )，柔軟的耐擦傷性樹脂 板時，可更進一步提高本發明之利用性。 如前述（8 ) ’形成前述靜摩擦係數未達0.4之硬化 被膜的面朝液晶面側設置時，具有行動電話等之攜帶型資 訊終端之顯示窗保護板所要求的透明性，表面硬度優異的 特性，且可有效的使背面產生之牛頓環消失，可保護攜帶 型資訊終端之顯示窗’提高其可靠性。 〔實施發明之形態〕 本發明之耐擦傷性樹脂板係在樹脂基板之兩面形成有 特定的硬化被膜。構成前述樹脂基板的樹脂例如有甲基丙 烯酸樹脂等之丙烯酸系樹脂、聚碳酸酯樹脂、聚苯乙烯樹

板形成多層構造。藉此可提高樹脂基板的剛性。層合數爲 2層以上，較佳爲2~4層。 樹脂基板爲多層構造時’較佳爲至少1層爲甲基丙烯 酸樹脂層。具體例如，含有後述之橡膠粒子的甲基丙烯酸 樹脂層與不含橡膠粒子之甲基丙烯酸樹脂層之多層構造、 玻璃轉化溫度不同之甲基丙烯酸樹脂層之多層構造、甲基 丙烯酸樹脂層與聚碳酸酯樹脂層之多層構造、甲基丙嫌酸 -10- 201002768 樹脂層與苯乙烯系樹脂層之多層構造等。 又，樹脂基板爲多層構造時’表層爲甲基丙稀酸樹脂 層，在耐擦傷性的觀點較佳。其厚度係兩表層爲甲基丙嫌 酸樹脂層時，各表層之厚度通常爲3μηι以上’較佳爲 ΙΟμιη以上，更佳爲30μιη以上。表層之甲基丙烯酸樹脂層 之厚度爲前述厚度，可得到充分的表面硬度。 表層之甲基丙烯酸樹脂層中，可在不使表面硬度降低 的範圍內，可含有橡膠粒子。橡膠粒子之含量通常爲在甲 基丙烯酸樹脂中1重量％以上50重量％以下，較佳爲30 重量％以下，更佳爲20重量％以下。 多層構造之樹脂基板特別是聚碳酸酯樹脂層之至少一 面被層合甲基丙烯酸樹脂層所成的層合板，其機械強度高 ，耐擦傷性優異，因此較適用。此層合板中，聚碳酸酯樹 脂層之厚度可爲整體厚度之5 0%以上。又，甲基丙烯酸樹 脂層之厚度係在聚碳酸酯樹脂層之兩面被層合甲基丙烯酸 樹脂層時，各甲基丙烯酸樹脂層之厚度與上述同樣，通常 爲3μιη以上，較佳爲ι〇μπ1以上，更佳爲30μιη以上，又 ’通常爲 12〇μιη以下，較佳爲 11〇μηι以下，更佳爲 ΙΟΟμιη以下。聚碳酸酯樹脂層之兩面層合甲基丙烯酸樹脂 層時’兩甲基丙烯酸樹脂層，其組成或厚度彼此可相同或 不同。 樹脂基板從賦予耐衝撃性的觀點，含有橡膠粒子者較 佳。可使用橡膠粒子之種類例如丙烯酸系、丁二烯系、苯 乙嫌-丁二烯系等的橡膠，其中丙烯酸系者在所得之樹脂 -11 - 201002768 基板之表面硬度、耐候性、耐衝撃性等諸物性之平衡方面 較佳。丙烯酸系橡膠粒子可使用例如以丙烯酸丁酯之丙烯 酸烷酯爲主成分之彈性聚合物所構成之單層構造者或在以 甲基丙烯酸甲酯爲主成分之硬質聚合物所構成之内層的周 圍，設置以丙烯酸丁酯之丙烯酸烷酯爲主成分之彈性聚合 物所構成之外層的多層構成者等、公知的丙烯酸系橡膠粒 子。彈性聚合物一般爲交聯性之多官能單體少量共聚合。 又，於彈性聚合物周圍設置有以甲基丙烯酸甲酯爲主 成分之硬質聚合物所構成之最外層的構造者也適用。例如 於以丙烯酸丁酯之丙烯酸烷酯爲主成分之彈性聚合物所構 成之內層周圍，設置有由丙烯酸丁酯之丙烯酸烷酯爲主成 分之彈性聚合物所構成之中間層，再於其周圍設置以甲基 丙烯酸甲酯爲主成分之硬質聚合物所構成之最外層的三層 構造者等。此種多層構造的橡膠粒子係揭示於例如日本特 公昭55-27576號公報。特別是上述三層構造者較佳，日 本特公昭55-27576號公報之實施例3所記載者係較佳的 組成之一。 橡膠粒子之平均粒徑可依該粒子適當選擇’其中該平 均粒徑爲0.1〜0.4 μχη之範圍者特佳。橡膠粒子之平均粒徑 在此範圍時，可得到耐衝擊性高、表面硬度優’表面平滑 的樹脂基板。橡膠粒子的平均粒徑過小時’表面硬度不足 ，或樹脂基板會變脆。此外’其平均粒徑過大時，可能影 響樹脂基板的表面平滑性。這種橡膠粒子一般而言可藉由 乳化聚合而製造。橡膠粒子的平均粒徑係藉由調節乳化聚 -12- 201002768 合之乳化劑的添加量或單體的投給量’可控制在所需要之 數値。 將橡膠粒子分散於丙烯酸系樹脂中，作爲樹脂基板時 ，兩者的比例較佳爲丙烯酸系樹脂爲50〜95重量份、橡膠 粒子爲5〜50重量份的範圍。橡膠粒子的量過少時，所得 之樹脂基板有變脆的傾向，因此不佳。而量過多時，耐熱 性或剛性有降低的傾向，故不佳。 樹脂基板係如通常的板（薄片）或薄膜，表面可爲平 面者，或如凸透鏡或凹透鏡等，表面成爲彎曲面者。 樹脂基板必要時可被著色劑、顏料等著色，可含有添 加劑例如氧化防止劑或紫外線吸收劑等。樹脂基板之厚度 通常爲 0.1〜3.0mm， 較佳爲 0.2〜2.0mm， 更佳爲 〇·3〜1.5 mm。這種厚度的樹脂基板柔軟，使用於本發明的 耐擦傷性樹脂板時，可進一步提高本發明之使用性。 樹脂基板可藉由擠壓成型來製造。擠壓成型具體而言 W藉由如T型模頭法或吹塑成型法等之熔融擠壓法來進行 。所得之樹脂基板表面可爲平滑。如欲賦予平滑性時，將 原料樹脂從例如由T型模頭熔融擠出，並使所得板狀物之 至少一面接觸於表面爲鏡面或皮帶（b e 11 )進行製板的方 法’由於能獲得表面性狀良好的樹脂基板，因此較佳。此 時輕筒可使用例如高剛性的金屬輥筒、具有彈性的橡膠輥 筒 '具有彈性的金屬輥筒等，這些輥筒可適當選擇或組合 使用。欲製造多層構造的樹脂基板時，可採用例如複數的 濟壓機’與具有爲將從之後所擠出之樹脂加以層合用之多 -13- 201002768 岐管（multimanifold)方式或分流塊（Feed Block)方式 等機構之周知的多層擠壓機。 本發明係在前述樹脂基板之兩面形成特定的硬化被膜 ，作爲耐擦傷性樹脂板。此時，其中一面之硬化被膜之形 成係使用可形成相對於前述樹脂基板之靜摩擦係數爲未達 〇 . 4的硬化被膜的硬化性塗料〔以下有時將此硬化性塗料 稱爲塗料（A)〕來進行。另一面之硬化被膜之形成係使 用可形成相對於前述樹脂基板之靜摩擦係數爲0.4以上之 硬化被膜的硬化性塗料〔以下有時將此硬化性塗料稱爲塗 料（B )〕來進行。如此，在樹脂基板之表背兩面使用各 自不同塗料（A ) 、（ B )形成硬化被膜，可得到即使與液 晶構件之偏光板接觸，牛頓環也容易消失的耐擦傷性樹脂 板。 塗料（A ) 、（ B )所含有之硬化性化合物，較佳爲使 用具有藉由照射電子線或紫外線等活性化能量線，產生硬 化之性質的化合物，特佳爲使用多官能（甲基）丙烯酸酯 化合物。其中多官能（甲基）丙烯酸酯化合物係指分子中

前述微粒子之添加量係相對於硬化性化合物1 〇〇重量 份，通常爲0.5〜50重量份，較佳爲1~20重量份。此添加 量太少時，無法使靜摩擦係數未達〇.4，而添加量太多時 ，透明性降低。 賦予滑性的添加劑，例如有聚砂氧油（s i 1 i c 0 n e 0 i1 ) 等。該聚矽氧油可使用一般者，具體例有二甲基聚矽氧油 、苯基甲基聚矽氧油、烷基•芳烷基改性聚矽氧油、含氟

201002768 ，使用0.1〜2重量份，較佳爲0.1〜1.0重量份。此使用量 較少時，無法使摩擦係數成爲未達0.4，而使用量太多時 ，硬化被膜之透明性會降低。 此外，樹脂基板之另一面所形成之硬化被膜的靜摩擦 係數爲0.4以上，較佳爲0.4〜1 .5，但是這種硬化被膜由塗 料（B )所形成時，例如在該塗料（B )中不要添加上述說 明之微粒子或滑性的添加劑即可。 以塗料（B )形成的硬化被膜必須具有攜帶型資訊終 端之顯示窗保護板所需的耐擦傷性。具體而言，要滿足後 述使用鋼綿的耐擦傷性及鉛筆硬度爲2H以上，較佳爲3H 以上。前述鉛筆硬度係依據JIS K 5 600所測定的値。欲賦 予前述硬化被膜所定的耐擦傷性時，藉由調整例如調配於 塗料（B )中之前述硬化性化合物的組成或量、後述導電 性微粒子的量等，而任意進行。 對於以塗料（B )形成的硬化被膜可賦予防靜電性能 ’使塵埃不易附著。具體而言，以塗料（B)形成之靜摩 擦係數爲0.4以上的硬化被膜可具有1〇9〜1〇14Ω/□之表面 電阻率。前述表面電阻率係如後述，依據AS TM D-25 7所 測得的値。 爲了將防靜電性能賦予前述硬化被膜時，例如有在塗 料（B )中添加導電性微粒子的方法等。前述導電性微粒 子例如有氧化銻（五氧化銻）之金屬氧化物、銦/錫之複 合氧化物（ITO )、被摻雜銻的氧化錫（AT0

panel of a portable information terminal and a display window protection panel using the portable information terminal thereof. [Prior Art] In recent years, mobile phones such as mobile phones or PHS (Personal Handy-phone System) have become popular with the Internet and have a simple voice transmission function. In addition, portable information terminals having the function of displaying text information or video information have been widely used. In addition, unlike the portable telephone type, in addition to the functions such as the address book, a PDA (Personal Digital Assistant) which has an Internet function or an e-mail function is also widely used. These portable information terminals display text information or video information by means of liquid crystal or EL (electroluminescence), etc., but in the display window, a transparent resin is generally used as a protective plate (see, for example, Japanese Patent Laid-Open 2002). Japanese Unexamined Patent Publication No. Hei. No. Hei. No. 2004-143365 Further, in order to prevent the surface of the protective sheet from being scratched, a cured film having scratch resistance (hardenability) by a curable coating material is proposed. Further, as the portable information terminal is thinned, it is required to be thinner for the display window protection panel. -5- 201002768 However, when the display window protection panel is made thinner, it is easier to become softer, and it is easier to come into contact with the liquid crystal surface (that is, the polarizing plate of the internal liquid crystal member). When the display window protector is in contact with the polarizing plate, an interference pattern called light of the Newton's ring is generated and does not disappear, so there is a problem that the image quality is lowered. [Disclosure of the Invention] An object of the present invention is to provide a scratch-resistant resin sheet having a cured film capable of suppressing deterioration of image quality on one surface of a resin substrate, and a display window protection board using the portable information terminal using the same . The inventors of the present invention have found a solution to the above-described problems in order to solve the above problems. (1) A scratch-resistant resin sheet characterized in that a hard coating film having a static friction coefficient of less than 〇·4 with respect to the resin substrate is formed on one surface of the resin substrate, and a static friction coefficient of the other surface with respect to the resin substrate is A hardened film of 0.4 or more is formed. (2) The scratch-resistant resin sheet according to the above item (1), wherein the hardened film having a static friction coefficient of 0.4 or more has a surface resistivity of from 109 to 1 〇 14 Ω/□. (3) The scratch-resistant resin sheet according to the above item (1) or (2), wherein the resin substrate has a thickness of 0.3 to 1.5 mm. (4) The scratch-resistant resin sheet according to any one of the above (1), wherein the resin substrate is an acrylic resin sheet. (5) The scratch-resistant resin sheet according to any one of the above items (1) to (3), wherein the resin substrate is a layer of a methacrylic resin layer laminated on at least one side of the polycarbonate resin layer The resulting laminate. (6) The scratch-resistant resin sheet according to any one of the items (1) to (5), wherein the resin substrate contains rubber particles. (7) A display window protection panel of a portable information terminal, characterized in that it is composed of the scratch-resistant resin sheet of any one of the above items (1) to (6). (8) The display window protection panel of the portable information terminal according to the above (7), wherein the surface of the hardened film having the static friction coefficient of less than 0.4 is formed facing the liquid crystal surface side. The aforementioned "portable information terminal" of the present invention is a general name for a person who can carry a window (disp 1 ay ) for displaying text information or video information, such as the mobile phone or PHS exemplified above. PDA, etc. According to the present invention, a hardened film having a static friction coefficient of less than 0.4 with respect to the resin substrate is formed on one surface of the resin substrate, and thus the cured film contacts the polarizing plate of the liquid crystal member, and even if a Newton ring is produced, the hardened film is on the polarizing plate. By sliding away from the polarizing plate, the Newton's ring easily disappears. Therefore, according to the present invention, even if a Newton's ring is produced, it can be instantly disappeared, and the effect of suppressing deterioration of image quality can be obtained. Further, since the predetermined hardened film is formed on the other surface, the scratch-resistant resin sheet is used as a display window protection plate of the portable information terminal, and the display window can be effectively protected. In particular, when the cured film having a static friction coefficient of 0.4 or more has a surface resistivity of 1 〇 9 to 1 〇 14 Ω/□, the dust can be prevented from adhering to the cured film. 201002768 When the present invention is applied to a soft scratch-resistant resin sheet as described in the above (3), the usability of the present invention can be further improved. (8) 'When the surface of the cured film having a static friction coefficient of less than 0.4 is formed on the liquid crystal surface side, the display window protective sheet of the portable information terminal such as a mobile phone is required to have transparency and excellent surface hardness. And it can effectively make the Newton ring generated on the back side disappear, and can protect the display window of the portable information terminal to improve its reliability.

An alkyl cyano compound such as an unsaturated carboxylic acid, acrylonitrile or methacrylonitrile. The polycarbonate resin may be obtained by, for example, reacting a dihydric phenol with a carbonylating agent by an interfacial polycondensation method or a melt transesterification method, and polymerizing the carbonate prepolymer by a solid transesterification method or the like to form a ring. The carbonate compound is obtained by polymerization in a ring-opening polymerization method or the like.

It is particularly preferred to use bisphenol A alone or in combination with bisphenol A and a compound selected from the group consisting of U1-bis(4-diphenyl)-3,5,5-trimethylcyclohexane, 2,2-double { ( One or more dihydric phenols in a group of 4, hydroxy-3.methyl)phenyl}propane and α,α'-bis(4-hydroxyphenyl)-m-diisopropylbenzene. The mineralization agent may be, for example, a mercapto halide such as phosgene (ph 〇sge η ), a carbonate such as diphenyl carbonate, or a haloformate such as a dihaloformate of a dihydric phenol. Two or more of these may be used. The resin substrate is not limited to a single layer, and a resin substrate having a different composition may be laminated to form a multilayer structure. Thereby, the rigidity of the resin substrate can be improved. The number of laminations is 2 or more, preferably 2 to 4. When the resin substrate has a multilayer structure, it is preferred that at least one layer is a methacrylic resin layer. Specifically, for example, a multilayer structure including a methacrylic resin layer containing rubber particles described later and a methacrylic resin layer containing no rubber particles, a multilayer structure of a methacrylic resin layer having a different glass transition temperature, a methacrylic resin layer and a poly The multilayer structure of the carbonate resin layer, the methyl propylene sulphate-10-201002768 multilayer structure of the resin layer and the styrene resin layer, and the like. Further, when the resin substrate has a multilayer structure, the surface layer is a methyl acrylate resin layer, which is preferable from the viewpoint of scratch resistance. When the thickness of the two surface layers is a methyl propylene succinic resin layer, the thickness of each surface layer is usually 3 μηι or more, preferably ΙΟμηη or more, more preferably 30 μmη or more. The thickness of the surface layer methacrylic resin layer is the aforementioned thickness, and sufficient surface hardness can be obtained. In the methacrylic resin layer of the surface layer, rubber particles may be contained in a range in which the surface hardness is not lowered. The content of the rubber particles is usually 1% by weight or more and 50% by weight or less, preferably 30% by weight or less, and more preferably 20% by weight or less based on the methacrylic resin. The resin substrate having a multilayer structure, in particular, a laminate obtained by laminating at least one surface of a polycarbonate resin layer with a methacrylic resin layer is excellent in mechanical strength and excellent in scratch resistance. In the laminate, the thickness of the polycarbonate resin layer may be more than 50% of the overall thickness. Further, when the thickness of the methacrylic resin layer is such that the methacrylic resin layer is laminated on both surfaces of the polycarbonate resin layer, the thickness of each methacrylic resin layer is usually 3 μm or more, preferably ι, as described above. Ππ1 or more, more preferably 30 μmη or more, and 'usually 12 〇μηη or less, preferably 11 〇μηι or less, more preferably ΙΟΟμιη or less. When the methacrylic resin layer is laminated on both sides of the polycarbonate resin layer, the two methacrylic resin layers may have the same or different compositions or thicknesses. The resin substrate is preferably one containing rubber particles from the viewpoint of imparting impact resistance. A rubber type such as an acrylic type, a butadiene type, a styrene-butadiene-butadiene type rubber, or the like, wherein the surface hardness, weather resistance, and impact resistance of the obtained resin -11 - 201002768 substrate can be used. It is better to balance the physical properties. As the acrylic rubber particles, for example, a single layer structure composed of an elastic polymer containing butyl acrylate as a main component or an inner layer composed of a hard polymer containing methyl methacrylate as a main component can be used. A known rubber-based rubber particle such as a multilayered structure of an outer layer composed of an elastomeric polymer containing butyl acrylate as a main component. The elastomeric polymer is generally a small amount of a cross-linking polyfunctional monomer copolymerized. Further, a structure in which an outermost layer composed of a hard polymer containing methyl methacrylate as a main component is provided around the elastic polymer is also applicable. For example, an intermediate layer composed of an elastomeric polymer containing butyl acrylate as a main component is provided around an inner layer composed of an elastomeric polymer containing butyl acrylate as a main component, and then A three-layer structure of the outermost layer composed of a hard polymer containing methyl methacrylate as a main component is provided. Such a rubber particle of a multilayer structure is disclosed, for example, in Japanese Patent Publication No. 55-27576. In particular, the three-layer structure is preferred, and the one described in the third embodiment of Japanese Patent Publication No. 55-27576 is one of preferable compositions. The average particle diameter of the rubber particles can be appropriately selected depending on the particle, wherein the average particle diameter is in the range of 0.1 to 0.4 μχη. When the average particle diameter of the rubber particles is within this range, a resin substrate having high impact resistance and excellent surface hardness can be obtained. When the average particle diameter of the rubber particles is too small, the surface hardness is insufficient, or the resin substrate becomes brittle. Further, when the average particle diameter is too large, the surface smoothness of the resin substrate may be affected. Such rubber particles are generally produced by emulsion polymerization. The average particle diameter of the rubber particles can be controlled to a desired number by adjusting the amount of the emulsifier -12-201002768 to be added or the amount of the monomer to be fed. When the rubber particles are dispersed in the acrylic resin, the ratio of the two is preferably 50 to 95 parts by weight of the acrylic resin and 5 to 50 parts by weight of the rubber particles. When the amount of the rubber particles is too small, the obtained resin substrate tends to become brittle, which is not preferable. On the other hand, when the amount is too large, heat resistance or rigidity tends to decrease, which is not preferable. The resin substrate is, for example, a usual plate (sheet) or film, and the surface may be a flat surface, or a convex lens or a concave lens, and the surface may be a curved surface. The resin substrate may be colored by a coloring agent, a pigment or the like as necessary, and may contain an additive such as an oxidation preventing agent or an ultraviolet absorber. The thickness of the resin substrate is usually 0.1 to 3.0 mm, preferably 0.2 to 2.0 mm, more preferably 3 to 1.5 mm. When the resin substrate having such a thickness is soft and is used in the scratch-resistant resin sheet of the present invention, the usability of the present invention can be further improved. The resin substrate can be produced by extrusion molding. The extrusion molding is specifically carried out by a melt extrusion method such as a T-die method or a blow molding method. The surface of the obtained resin substrate can be smooth. When smoothness is to be imparted, the raw material resin is melt-extruded from, for example, a T-die, and at least one side of the obtained plate is brought into contact with the surface to be a mirror or a belt (be 11). A resin substrate having a good surface property is preferred. At this time, the light cylinder can be, for example, a highly rigid metal roll, a flexible rubber roll, a flexible metal roll, or the like, which can be appropriately selected or used in combination. In order to manufacture a resin substrate having a multilayer structure, for example, a plurality of presses can be used, and a multi-manifold method or a flow block having a laminate for laminating the resin to be extruded from the back can be used. A well-known multi-layer extruder of a mechanism such as a system. In the present invention, a specific hardened film is formed on both surfaces of the resin substrate as a scratch-resistant resin sheet. In this case, a hardening coating which forms a hardened film having a static friction coefficient with respect to the resin substrate of not more than 0.4 is used for the formation of the hardened film on one of the surfaces (hereinafter, this curable coating is sometimes referred to as a coating (A). ] Come and proceed. On the other hand, the hardened coating film is formed by using a curable coating material (hereinafter referred to as a coating material (B)) which forms a hardened film having a static friction coefficient of 0.4 or more with respect to the resin substrate. In this manner, a cured film is formed on each of the front and back surfaces of the resin substrate by using the respective coating materials (A) and (B), and a scratch-resistant resin sheet in which the Newton ring easily disappears even when it is in contact with the polarizing plate of the liquid crystal member can be obtained.

The aromatic monomer may, for example, be a monofunctional monomer such as styrene, α-methylstyrene or ethylvinylbenzene or a polyfunctional monomer such as divinylbenzene. These monofunctional monomers and polyfunctional single systems are used singly or in combination of two or more. When the organic fine particles are to be obtained, the above monomer mixture can be polymerized to obtain ', but when the desired particle diameter is desired, the emulsion polymerization method is preferred. -17-201002768 The inorganic fine particles are, for example, a metal oxide such as cerium oxide, aluminum oxide, titanium oxide or zirconia. These may be used alone or in combination of two or more. These inorganic fine particles exemplified can be used in the form of a sol. The organic fine particles and the inorganic fine particles may be used in combination. The volume average particle diameter of the fine particles is preferably from 0.05 to Ιμιη, more preferably from 0.08 to 0.5 μm. When the volume average particle diameter is less than 〇·〇5μηη, in order to make the static friction coefficient less than 0.4, it is necessary to add a large amount of fine particles, and when it is larger than 1 μm, the transparency is lowered. The volume average particle diameter is as follows, and the enthalpy obtained by a dynamic light scattering type particle size distribution measuring apparatus is used. The amount of the fine particles added is usually 0.5 to 50 parts by weight, preferably 1 to 20 parts by weight, based on 1 part by weight of the curable compound. When the amount of addition is too small, the static friction coefficient cannot be made up to 44, and when the amount is too large, the transparency is lowered.

When the amount of use is small, the coefficient of friction cannot be made less than 0.4, and when the amount used is too large, the transparency of the cured film is lowered. Further, the hard coat film formed on the other side of the resin substrate has a static friction coefficient of 0.4 or more, preferably 0.4 to 1.5, but when the hardened film is formed of the coating material (B), for example, in the coating material (B) Do not add the above-mentioned microparticles or slippery additives. The hardened film formed of the coating (B) must have the scratch resistance required for the display window protection board of the portable information terminal. Specifically, the scratch resistance and the pencil hardness of the steel wool to be used later are 2H or more, preferably 3H or more. The aforementioned pencil hardness is enthalpy measured in accordance with JIS K 5 600. When it is desired to impart the scratch resistance to the hardened film, the composition or amount of the curable compound to be blended in the coating material (B), the amount of the conductive fine particles described later, and the like are arbitrarily adjusted. The hardened film formed of the coating material (B) can be imparted with antistatic properties. Specifically, the cured film formed by the coating material (B) having a static friction coefficient of 0.4 or more may have a surface resistivity of from 1 〇 9 to 1 〇 14 Ω / □. The aforementioned surface resistivity is as described later, based on the enthalpy measured by ASTM D-25 7. In order to impart antistatic properties to the cured film, for example, a method of adding conductive fine particles to the coating (B) may be employed.

The volume average particle diameter of the conductive fine particles is preferably 0.001 to ΙμΓΠ. The above-mentioned particle size is too small to be industrially difficult to produce, and when the above particle diameter is too large, the transparency of the cured film is lowered, which is not preferable. Further, the amount of the conductive fine particles used in the coating material is preferably from 1 to 100 parts by weight based on 100 parts by weight of the curable compound. When the amount used is too small, the resulting scratch-resistant resin sheet is easily cracked when it is pressed, and a sufficient antistatic effect cannot be obtained. When the amount is too large, the scratch resistance of the cured film is lowered, or the film formability is lowered. So not good. The coating materials (A) and (Β) may contain a solvent in order to adjust the viscosity and the thickness of the cured film. Such solvents are, for example, methanol, ethanol, 1-propanol, 2-propanol (isopropanol), 1-butanol, 2-butanol (sec-butanol), 2-methyl-1-propanol (different) Butanol), 2-methyl-2-propanol (tert-butanol) alcohol, 2-ethoxyethanol, 2-butoxyethanol, 3-methoxy-1-propanol, 1- Methoxy-2-propanol, alkoxy alcohols of 1-ethoxy-2-propanol, ethyl ketone alcohols of diacetone alcohol, acetone, methyl ethyl ketone, methyl ketone of methyl isobutyl ketone An aromatic hydrocarbon such as toluene or xylene, an ester of ethyl acetate or butyl acetate, and the like.

Further, the coating materials (A) and (B) may contain additives such as a stabilizer, an oxidation inhibitor, a colorant, a fluorine-based or an acrylic-based flat agent, if necessary. -20- 201002768 The coatings (A) and (B) described above are applied to one surface of the resin substrate, and then dried if necessary, and then the formed coating film is cured to obtain the scratch resistance of the present embodiment. Resin board. The order of application hardening of the two coatings may be arbitrary or may be carried out simultaneously. The coating of the coatings (A) and (B) may be carried out by applying a mask on one side as necessary, for example, a micro gravure coating method, a roll coating method, a dip coating method, a spin coating method, a die coating method, It is carried out by a method such as a mold transfer method, a flow coating method, or a spray coating method. The hardening of the coating film is carried out by irradiating the activated energy rays. The active energy ray is, for example, an electron beam, an ultraviolet ray, a visible ray or the like, and can be appropriately selected in accordance with the type of the curable compound. When an ultraviolet ray or visible ray is used for the activated energy ray, a photopolymerization initiator is usually used. The photopolymerization initiators include, for example, acetophenone, phenethyl benzyl ketal, anthracene, 1-(4-isopropylphenyl)-2-hydroxy-2-methylpropan-1-one, and taste. Azole, xanthone, 4-chlorobenzophenone, 4,4,-diaminobenzophenone, dimethoxydeoxybenzoin, 3,3'-dimethyl-4-methoxy Benzophenone, thioxanthone, 2,2-dimethoxy-2-phenylacetophenone, iota-(4-laurylphenyl)-2-hydroxy-2-methylpropan-1-one , 2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropan-1-one, triphenylamine, 2,4,6-trimethylbenzhydrazene diphenyl Phosphine oxide, 1-hydroxy-cyclohexyl phenyl ketone, 2-hydroxy-2-methyl-1-phenylpropan-1-one, anthrone, anthracene, benzaldehyde, benzoin ethyl ether, benzoin Propyl ether, benzophenone, Michler's ketone, 3-methylacetophenone, 3,3',4,4, tetra (tert-butylperoxycarbonyl)benzophenone (BTTB), 2-( Dimethylamino)-1-[4-(morpholino)phenyl]-2.(phenylmethyl)-indole-butyl copper, -21 - 201002768 4-benzhydryl-4'-methyl Diphenyl sulfide, benzyl, and the like. The aforementioned photopolymerization initiator can be used in combination with a dye sensitizer. The dye sensitizer is, for example, xanthone, thioxanthone, coumarin, oxycoumarin or the like. The combination of the photopolymerization initiator and the dye sensitizer is, for example, a combination of B T TB and xanthonone, a combination of BTTB and thioxanthone, a combination of BTTB and coumarin, a combination of BTTB and oxocoumarin, and the like. The upper sB photopolymerization initiator can be used for the sale of the towel. The photopolymerization initiators sold by the company are, for example, "IRGACURE 651", "IRGACURE 184", "IRGACURE 500", "IRGACURE 1000", "IRG A CURE 2 9 5" manufactured by Ciba· Speciality Chemicals Co., Ltd., respectively. 9,, "DAROCUR 1173", "IRGACURE 907", "IRGACURE 369", "IRGACURE 1 700", "IRGACURE 1 800", "IRGACURE 8 1 9", and "IRG A CURE 7 84", respectively, from Japan "KAYACURE ITX", "KAYACURE DETX-S", "KAYACURE BP-100", "KAYACURE BMS"' and "KAYACURE 2-EAQ" sold by Chemicals Co., Ltd., etc. When using a photopolymerization initiator, The amount used is usually 0.1 part by weight or more based on 100 parts by weight of the curable compound. When the amount used is too small, the curing rate does not tend to increase as compared with the case where no photopolymerization initiator is used. The upper limit of the amount of the initiator to be used is usually 10 parts by weight based on 1 part by weight of the curable compound. Further, the intensity of the activated energy ray and the irradiation time are based on the type of the curable compound or the thickness of the coating film. Appropriate adjustment The activated energy line can be irradiated in an inert gas atmosphere. The inert gas can be a nitrogen gas or a gas 1-22-201002768 body. The thickness of the hardened film formed is preferably 1 to 1 〇μιη, and more preferably. Preferably, the thickness is 2 to 8 μηι. If the thickness is too small, the scratch resistance is insufficient. When the thickness is too large, the transparency is lowered. Or when it is under high temperature and high humidity, cracks are likely to occur. The thickness of the cured film can be adjusted by coating. The amount of the area unit of the curable coating material on the surface of the resin substrate or the concentration of the solid content contained in the curable coating material is arbitrarily adjusted.

INDUSTRIAL APPLICABILITY According to the present invention, a cured film having a static friction coefficient of less than 〇·4 with respect to the resin substrate is formed on one surface of the resin substrate. Therefore, the cured film contacts the polarizing plate of the liquid crystal member, and even a Newton's ring is generated. The hardened film leaves the polarizing plate by sliding on the polarizing plate, so the Newton's ring easily disappears. Therefore, according to the present invention, even if a Newton's ring is produced, it can be instantly disappeared, and the effect of suppressing deterioration of image quality can be obtained. Further, since the predetermined hardened film is formed on the other surface, the scratch-resistant resin sheet is used as a display window protection plate of the portable information terminal, and the display window can be effectively protected.
