Abstract

A curable resin composition which can give cured products of superior impact resistance, superior flexibility, thermal shock resistance, storage stability and adhesiveness, and which comprises PA1 A. either (1) a polyepoxide compound containing at least two 1,2-epoxy groups per molecule or (2) an unsaturated polyester having a molecular weight of 500 to 5,000. PA1 B. a specified aromatic copolyester having a weight average molecular weight of 10,000 to 100,000 and PA1 C. either (1) a curing agent for the polyepoxide compound (A-1) or (2) an ethylenic monomer copolymerizable with the unsaturated polyester (A-2).
