PURPOSE:A resin composition which is excellent in coatability and flame retardancy and can give a laminate excellent in heat resistance, impact resistance, etc., obtained by mixing specified two bisphenol A epoxy resins with a bisphenol and a novolak resin. CONSTITUTION:A bisphenol A diepoxy resin (A) of a MW <=500, a bisphenol (B) of formula I (wherein R1 is a 1-3 C linear alkylene, R2 and R3 is a 1-3 C alkyl or alkenyl), e.g., bisphenol A, a bisphenol A novolak polyepoxy resin (C) of formula II (wherein R1 and R2 are each a 1-3 C alkyl or alkenyl and n is 1-3) and a novolak resin (D) as a curing agent are prepared. These components are mixed together in such amounts that 5-50pts.wt. component C is present per 100pts.wt. total of components A and C to obtain the purpose resin composition for laminates.
