Abstract: The present invention relates to an aqueous binder dispersion for cathodic electrodeposition coatings obtained A) by reacting I. a precursor prepared at temperatures of from 120 to 180° C. from a) a diepoxide compound or a mixture of diepoxide compounds and b) an aromatic or aliphatic compound hydroxyl, carboxyl, phenol and/or thiol groups, or a mixture of such compounds with reaction of the phenolic hydroxyl groups with epoxide groups, II. with at least one organic amine or a mixture of organic amines at a temperature between 60 and about 130° C. to give an epoxide/amine adduct; B) subsequently or simultaneously reacting at least one secondary hydroxyl group of the precursor with an unreacted epoxide group of the epoxide/amine adduct prepared in step A) at a temperatures of from about 110 to about 150° C.; C) adding a crosslinking agent at a temperature of less than about 150° C.
