A polyester-amide-imide wire enamel blend is disclosed which is made up of four components-a cross-linkable polyester, a linear polyester, a polyester amide-imide component, and a cresol formaldehyde resin. The cross-linkable polyester is the reaction product of a polyol which is mixture of diol and a triol, a polyfunctional carboxylic compound, and a catalyst. The linear polyester is the reaction product of a diol, a polyfunctional carboxylic compound, and a catalyst. The polyester-amide-imide component is the reaction product of a diamine, trimellitic anhydride, and a polyester which in turn is the reaction product of a polyol, a polyfunctional carboxylic compound, and a catalyst. The cresol formaldehyde resin is the reaction product of a phenol, formaldehyde, and a amine catalyst. All of the four components are in a solution of a carbitol. The polyester-amide-imide wire enamel blend also contains a fatty acid component which may be reacted into any of its polyester components.
