PROBLEM TO BE SOLVED: To obtain a polyamideimide based heat-resistant resin composition having excellent wear resistance and flexibility, a coating material which uses this heat-resistant resin composition as the film-forming component, and an enamel wire having excellent wear resistance and flexibility which uses this coating material. SOLUTION: The heat-resistant resin composition comprises a polyamideimide resin and a heterocyclic mercaptan represented by formula (I) (wherein A is a group to form a 5 or 6-memebered hetero ring together with a group of formula (II) and has a main chain composed of two or three carbon atoms bonded by a single bond or a double bond, two or three carbon atoms forming a part of one aromatic ring, two nitrogen atoms bonded by a single bond or a double bond, or one carbon atom and one or two nitrogen atoms bonded by a single bond or a double bond; and X is oxygen atom, sulfur atom, carbon atom or nitrogen atom and the carbon atom or the nitrogen atom is substituted with hydrogen atom, a 1-4C alkyl group, phenyl group or mercapto group). The coating material and the enamel wire use this heat-resistant resin composition.
