Abstract
Abstract An insulated wire comprising a conductor coated and baked thereon with an insulating lacquer, the insulating lacquer comprising (a) 100 parts by weight of a polyamideimide resin having a molecular weight corresponding to a reduced specific viscosity of from 0.1 to 1.0, and (b) 75 to 400 parts by weight of a stabilized polyisocyanate compound derived from diphenylmethanediisocyanate.
