Description

耐光性硬塗覆材料Light resistant hard coating material

[0001] 本發明為關於一種耐光性硬塗覆材料(硬化組成物)，其特徵為，適合作為用於觸控面板顯示器、液晶顯示器等各種顯示元件的表面之硬塗覆層之形成材料者。[0001] The present invention relates to a light-resistant hard coat material (hardened composition) characterized by being suitable as a material for forming a hard coat layer for a surface of various display elements such as a touch panel display or a liquid crystal display. .

[0002] 如個人電腦、行動電話、行動遊戲機、ATM等，為數非常多的搭載觸控面板之平板顯示器之產品已被商品化。尤其，因出現智慧型手機或平板電腦，具備多點觸控功能之靜電容式觸控面板的搭載數被大幅地提升。 　　[0003] 此些觸控面板顯示器表面使用了薄強化玻璃，並於顯示器表面貼上保護膜以防止此玻璃散射。保護膜，因使用塑膠膜故較玻璃易留下損傷，需於其表面鋪設抗擦傷性較佳之硬塗覆層。欲於塑膠膜表面賦予抗擦傷性，可舉例如，使用可形成高度交聯結構，即分子運動性較低之交聯結構使表面硬度提升，賦予對外力之抵抗性的方法。 　　此些硬塗覆層形成材料中，目前最常使用之多官能丙烯酸酯類材料，因其多數於常溫下為液狀單體，且會受到由光聚合引發劑產生之游離基形成3次元交聯。因丙烯酸酯類受紫外線(UV)會硬化，而因照射UV的時間非常短故可省能源，故以其產能高為特徵。於塑膠膜表面上形成硬塗覆層之方法，可舉例如，將多官能丙烯酸酯、光聚合引發劑及含有機溶劑之溶液使用凹版塗覆等塗覆於塑膠膜上，並於有機溶劑乾燥後，使用紫外線使其硬化，而形成硬塗覆層之方法。所形成之硬塗覆層中，欲使硬度、抗擦傷性等功能於實用上不產生問題之等級時，一般硬塗覆層之厚度為形成1～15μm。 　　[0004] 另外，靜電容式觸控面板為透過人的手指觸碰以進行操作。為此，進行操作時指紋會密著於觸控面板之表面，而會產生顯示器之影像能見度明顯的減少，且顯示器之外觀受損之問題。因指紋中含有汗水帶來之水份及皮脂帶來之油份，就使任何東西都難以密著之觀點，故高度期望對於顯示器表面之硬塗覆層，可賦予撥水性及撥油性。 　　由此觀點，觸控面板顯示器表面，極期望對指紋等具有防污性。但，靜電容式觸控面板中，因人會每天用手指觸碰，故即便初期之防污性達到相當高之等級，但伴隨使用過程其功能多有降低之情形。為此，使用過程的防污性之耐久性即成為發明之課題。 　　[0005] 過去，於硬塗覆層表面賦予防污性之方法，多使用於形成硬塗覆層之塗覆液中少量添加氟類表面改性劑之方法。所添加之氟類化合物，因其具有低表面能量而會偏存於硬塗覆層，而可賦予撥水性及撥油性。氟類化合物，就撥水性、撥油性之觀點，多使用具有聚(全氟伸氧烷基)鏈之被稱為全氟聚醚的具有1,000～5,000左右之數量平均分子量之寡聚物。但，因全氟聚醚具有高氟濃度，一般，較難溶解於形成硬塗覆層之塗覆液所使用之有機溶劑中。此外，於所形成之硬塗覆層中會產生凝聚現象。 　　欲對該些全氟聚醚中，賦予對於有機溶劑之溶解性及硬塗覆層中之分散性時，多會使用於全氟聚醚附加有機部位之方法。並且，為賦予抗擦傷性時，多會使用鍵結由(甲基)丙烯酸酯基代表之活化能量射線硬化部位之方法。 　　目前為止，具有抗擦傷性的防污性硬塗覆層中，對於硬塗覆層表面所賦予的防污性成份，已有揭示使用於聚(全氟伸氧烷基)鏈之兩終端，介由具有異佛酮架構之複數的胺基甲酸酯鍵結的具有(甲基)丙烯醯基之化合物作為表面改性劑之技術(專利文獻1)。 　　[0006] 另，欲於顯示器表面等基材表面使用防污性硬塗覆膜，需在與形成防污性硬塗覆層之面相反之面，使用光學透明黏著劑(OCA)，貼附於基材表面。OCA可透過加熱及照射活化能量射線硬化，發揮其黏著功能。藉由活化能量射線硬化的OCA之情形，雖為由防污性硬塗覆側照射活化能量射線以進行硬化，但該期間，因活化能量射線之照射，會自殘留於防污性硬塗覆層中之未反應的聚合引發劑產生游離基。並且，產生之游離基成為起始種，會使未反應之活化能量射線多官能單體之過度進行聚合，導致防污性硬塗覆層脆化，並引發防污性硬塗覆層及薄膜間之密著性降低，產生防污性硬塗覆層剝離之問題。為防止密著性降低，一般使用之手段，例如，於形成防污性硬塗覆層之硬化性組成物中，預先添加紫外線吸收劑及光穩定劑之方法(專利文獻2)。 [先行技術文獻] [專利文獻] 　　[0007] 　　[專利文獻1] 特開2013-76029號公報 　　[專利文獻2] 特開2016-125049號公報[0002] For example, personal computers, mobile phones, mobile game consoles, ATMs, etc., a large number of flat panel displays equipped with touch panels have been commercialized. In particular, the number of mounted capacitive touch panels with multi-touch capability has been greatly improved due to the emergence of smart phones or tablets. [0003] Such touch panel display surfaces use thin tempered glass, and a protective film is attached to the surface of the display to prevent scattering of the glass. The protective film is easy to leave damage to the glass due to the use of the plastic film, and a hard coating layer having a good scratch resistance is required to be applied to the surface. In order to impart scratch resistance to the surface of the plastic film, for example, a method of forming a highly crosslinked structure, that is, a crosslinked structure having a low molecular mobility, is used to increase the surface hardness and impart resistance to external force. Among these hard coating layer forming materials, polyfunctional acrylate materials which are most commonly used at present are mostly liquid monomers at normal temperature, and are subjected to a 3-dimensional cross by free radicals generated by a photopolymerization initiator. Union. Acrylates are hardened by ultraviolet rays (UV), and since UV irradiation is very short, energy is saved, so it is characterized by high productivity. A method of forming a hard coat layer on the surface of a plastic film, for example, applying a polyfunctional acrylate, a photopolymerization initiator, and an organic solvent-containing solution to a plastic film by gravure coating or the like, and drying the organic solvent. Thereafter, it is cured by using ultraviolet rays to form a hard coat layer. In the hard coating layer formed, when the function such as hardness and scratch resistance is to be practically not problematic, the thickness of the hard coat layer is generally 1 to 15 μm. [0004] In addition, the capacitive touch panel is operated by touching a human finger. For this reason, the fingerprint is adhered to the surface of the touch panel during operation, and the visibility of the image of the display is significantly reduced, and the appearance of the display is damaged. Since the moisture contained in the fingerprint and the oil from the sebum make it difficult to adhere to anything, it is highly desirable to impart water repellency and oil repellency to the hard coating layer on the surface of the display. From this point of view, the touch panel display surface is highly desirable to have antifouling properties against fingerprints and the like. However, in the capacitive touch panel, since the person touches with a finger every day, even if the initial antifouling property reaches a relatively high level, the function is often lowered with the use of the process. Therefore, the durability of the antifouling property of the use process is a subject of the invention. [0005] In the past, a method of imparting antifouling properties to the surface of a hard coat layer has been generally used in a method of adding a fluorine-based surface modifier to a coating liquid for forming a hard coat layer. The fluorine compound to be added is biased in the hard coat layer because of its low surface energy, and imparts water repellency and oil repellency. As the fluorine-based compound, an oligomer having a number average molecular weight of about 1,000 to 5,000, which is called a perfluoropolyether, having a poly(perfluoroalkyloxyalkyl) chain is often used from the viewpoint of water repellency and oil repellency. However, since the perfluoropolyether has a high fluorine concentration, it is generally difficult to dissolve in the organic solvent used for the coating liquid for forming the hard coat layer. In addition, agglomeration occurs in the formed hard coat layer. When the solubility in an organic solvent and the dispersibility in a hard coat layer are imparted to these perfluoropolyethers, a method of adding an organic site to the perfluoropolyether is often used. Further, in order to impart scratch resistance, a method of bonding an active energy ray-cured portion represented by a (meth) acrylate group is often used. Heretofore, in the antifouling hard coat layer having scratch resistance, the antifouling component imparted to the surface of the hard coat layer has been disclosed to be used for the two terminals of the poly(perfluoroextended alkyl) chain. A technique of using a compound having a (meth) acrylonitrile group bonded with a plurality of urethane groups of an isophorone structure as a surface modifier (Patent Document 1). [0006] In addition, in order to use an antifouling hard coat film on the surface of a substrate such as a display surface, it is necessary to use an optically clear adhesive (OCA) on the opposite side to the surface on which the antifouling hard coat layer is formed. On the surface of the substrate. OCA can be hardened by heating and irradiation to activate energy rays to exert its adhesive function. In the case of OCA which is activated by energy ray hardening, the active energy ray is irradiated by the anti-fouling hard coating side to perform hardening, but during this period, due to the irradiation of the active energy ray, the anti-fouling hard coating is left. The unreacted polymerization initiator in the layer generates a radical. Moreover, the radical formed is an initial species, which causes excessive polymerization of the unreacted activated energy ray polyfunctional monomer, resulting in embrittlement of the antifouling hard coating layer, and initiation of the antifouling hard coating layer and film. The adhesion between the two is lowered, resulting in the problem of peeling off the antifouling hard coat layer. In order to prevent a decrease in the adhesion, a method of generally adding a UV absorber and a light stabilizer to a curable composition forming an antifouling hard coat layer is used (Patent Document 2).

[發明欲解決之問題] 　　[0008] 專利文獻1具體記載之方法，因形成防污性硬塗覆層之硬化性組成物中不含紫外線吸收劑及光穩定劑，故存在由防污性硬塗覆層之膜發生剝離之疑慮。 　　又，專利文獻2具體記載之方法中，紫外線吸收劑會抑制由聚合引發劑產生游離基，又，光穩定劑會補捉產生之游離基使其猝滅(quench)。因此，預先於形成防污性硬塗覆層之硬化性組成物中添加紫外線吸收劑及光穩定劑之情形，即使於形成防污性硬塗覆層中，也會抑制游離基之產生及產生猝滅，而阻礙防污性硬塗覆層之形成，因而引發抗擦傷性之惡化。又，紫外線吸收劑，亦具有吸收400nm附近之種類，添加過多之情形，仍會有存在損害防污性硬塗覆層的透明性之情形。
