PURPOSE:To provide the titled compsn. having excellent flexibility and resistance to heat and chemicals, by blending a polymer having a specified functional group with a resin compsn. consisting of a solvent-soluble polyimide resin, an epoxy resin and a hardener. CONSTITUTION:The titled compsn. is obtd. by blending 10-100pts.wt. polymer having epoxy groups or a functional group reactive with epoxy group (e.g. epoxy group-contg. acrylic rubber) with 100pts.wt. resin compsn. consisting of a solvent- soluble polyimide resin, an epoxy resin contg. at least two epoxy groups per molecule (e.g. bisphenol A type epoxy resin) and a hardener (e.g. dicyandiamide). The compsn. has excellent resistance to heat and chemicals, flexibility, electrical insulating properties and adhesion.
