PROBLEM TO BE SOLVED: To obtain both a heat-resistant resin composition having a reduced amount of an organic solvent content, not causing the environmental pollution and deteriorating the operation environment, advantageous for safety and sanitation, having excellent characteristics of coating and coating film, and a coating comprising the resin composition as a coating film component. SOLUTION: This heat-resistant resin composition is obtained by mixing (A) a polyamide-imide resin obtained by reacting a diisocyanate compound or a diamine compound with a tribasic acid anhydride or a tribasic acid chloride in a basic polar solvent with (B) a basic compound and (C) water and the amount of the basic compound in the component (B) mixed is 1-20 equivalents based on the acid number obtained by adding the carboxy group contained in the polyamide-imide resin in the component (A) to the carboxy group obtained by subjecting the acid anhydride group in the polyamide-imide resin to ring opening.
