摘要
Provided is a flexible epoxy resin composition, which shows improved flexibility, heat resistance and electrical properties, and is useful for producing a copper clad laminate plate for a printed circuit board. The flexible epoxy resin composition comprises: (a) 20-40 parts by weight of an epoxy resin; (b) 40-70 parts by weight of a high-acid value epoxy acrylate resin; and (c) 20-40 parts by weight of an acid-modified polycarbonate. In the composition, the epoxy resin includes a novolac epoxy resin or bisphenol A epoxy resin. The composition may further comprise 1-80 parts by weight of a curing agent selected from amine-based curing agents, acid anhydride-based curing agents, imidazole and adipic acid.
