Abstract

The disclosed invention involves water-dispersible binding agents for cationic electrodeposition coatings and a method for making them, the binding agents are the reaction product of (A) epoxy resins having a molecular weight greater than about 350; (B) polyfunctional, alcohols, carboxylic acids and/or SH-compounds having a molecular weight between about 500-5000 and (C) aminoalcohols with at least one protected primary or tertiary nitrogen atom.
