RESIN COMPOSITION, METHOD FOR FORMING TRANSPARENT FILM, AND TRANSPARENT FILM

摘要

PURPOSE:To prepare a resin comps. capable of forming a protective film excellent in adhesion and surface smoothness on the surface of a glass plate, etc., by compounding a specific epoxy resin, a curative contg. an o-cresol novolac resin, and a specific solvent. CONSTITUTION:An epoxy resin composition is prepared from an epoxy resin comprising 5-90wt.% polyepoxy resin of the formula and 95-10wt.% glycidyl ether of a novolac resin, a curative contg. an o-cresol novolac resin softening at 100-140 deg.C, and an org. solvent mixture comprising 10-90wt.% org. solvent boiling at 180-200 deg.C (e.g. butyl cellosolve acetate or diethylene glycol monomethyl ether) and 90-10wt.% org. solvent boiling at 140-170 deg.C (e.g. ethyl cellosolve acetate).
