摘要： The present invention relates to a resin composition for protective films which comprises an epoxy resin having two or more epoxy groups, a curing agent, a curing accelerator, a solvent, and a colloidal slurry of fine silica particles having an average particle diameter, as determined by conversion from the specific surface area, of 50 nm or smaller, a pH of 6 to 8, and an alkali metal content of 5 ppm or lower. The resin composition gives a protective film which satisfies adhesiveness and visible-light transmission, which are performances conventionally required. The protective film further has high surface smoothness even when the substrate surface is not smoothed. The resin composition has satisfactory storage stability and does not stain liquid crystal. Furthermore, a cured film obtained from the resin composition has excellent high-temperature resistance, especially ITO resistance. The resin composition is hence suitable for use in forming a protective film for the colored resin films of color filters for liquid-crystal display.
摘要翻译：本发明涉及一种保护膜用树脂组合物，其包含具有两个以上环氧基的环氧树脂，固化剂，固化促进剂，溶剂和具有平均粒径的二氧化硅微粒的胶体浆料比表面积为50nm以下，pH为6〜8，碱金属含量为5ppm以下。树脂组合物得到满足粘合性和可见光透射性的保护膜，这是常规要求的性能。即使基板表面不平滑，保护膜还具有高的表面光滑度。该树脂组合物具有令人满意的储存稳定性，并且不会使液晶染色。此外，由树脂组合物获得的固化膜具有优异的耐高温性，特别是ITO电阻。因此，树脂组合物适用于形成液晶显示用滤色片的有色树脂膜用保护膜。
