| 摘要 |
The object of the present invention is to provide a composition for protective films excellent in adhesion and visible light transmittance that can form a protective film having high surface smoothness even on a substrate whose surface has not been smoothed and has extremely high resistance to thermal yellowing without staining liquid crystals. Especially, when used for protective films of color filters for liquid-crystal displays, the protective films have the excellent high-temperature resistance under ITO (yellowing resistance) vapor deposition. The composition for protective films is characterized by comprising (1) an epoxy resin having at least two epoxy groups in one molecule, (2) apolyphenol compound having a cyclic terpene skeleton, and (3) an imidazole-type curing promoter.
