Abstract

Process for obtaining varnishes based on polyester resins or polyesterimides, characterized in that it comprises polyesterifying at least one polycarboxylic acid comprising at least one pentagonal lactam cycle, or a compound capable of generating said acid, with at least one polyalcohol, said acid being prepared polycarboxylic by condensation of itaconic acid, or one of its substitution derivatives or its esters, with a primary amine which further comprises another primary amino group or a carboxyl group at its chain end.
