<p>A resin composition for protective films which comprises an epoxy resin having two or more epoxy groups, a hardener, a hardening 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 adhesion and visible-light transmission, which are performances conventionally required. The protective film further has high surface smoothness even when the substrate surface has not been smoothed. The resin composition has satisfactory storage stability and does not cause liquid-crystal fouling. Furthermore, the 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 displays.</p> |
