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.
