PURPOSE:To obtain a resin compsn. which forms a coating film excellent in appearance even when applied thick and in solderability, heat resistance, and thermal shock resistance by compounding an imidized polyester resin, a stabilized isocyanate, and a polyether sulfone resin. CONSTITUTION:A resin compsn. comprises an imidized polyester resin, a stabilized isocyanate, and a polyether sulfone resin in an amt. of 0.1-10wt.% based on the sum of the two foregoing components. The wt. ratio of the polyester resin to the isocyanate is pref. (1:1)-(1:10) from the viewpoint of the solderability and heat resistance of an insulated wire obtd. by coating a conductor with the compsn. and baking it. |
