Abstract: Amide-containing epoxy resin/amine adducts are prepared by a process in which an epoxy resin/amine adduct containing primary and/or secondary aminoalkyl groups is reacted with a carboxylic acid in the presence of esterification catalysts, particularly advantageously in the presence of an alcohol. The products prepared according to the invention are useful as binders for cathodic electrocoating.

Abstract: The heat-curable coating agent according to the invention contains a combination of a binder, which possesses basic nitrogen groups and is rendered water-dilutable by protonation with an acid, and a crosslinking agent and, if required, pigments, fillers, corrosion inhibitors, surface coating assistants and catalysts, and the binder used is a reaction product of a dicarboxylic acid or of a dicarboxylate or of a (meth)acrylate oligomer or polymer with an adduct of a di- or triglycidyl ether and a polyamine, the polyamine containing 2 or more amine nitrogen atoms per molecule and one or more alkylene chains of 3 or more carbon atoms between the amino groups, and has an NH amine number of from 50 to 150 mg of KOH/g and is combined with aminoplasts and/or phenoplasts as crosslinking agents. The novel coating agent is useful as a binder for the cathodic electrocoating of metal articles.
