Abstract

A resin composition comprising (A) a reaction product obtained by reacting (a) a polyvalent isocyanate, (b) a polyvalent carboxylic acid anhydride, and if necessary, (c) a polyvalent carboxylic acid, in an organic solvent, and (B) a compound having active hydrogen in the molecule except for a phenolic compound, shows excellent heat resistance and storage stability. Insulated wires obtained by coating said resin composition on an electric conductor directly or indirectly are advantageously produced.
