Abstract

Heat-curable aqueous coating agents for cathodic electrocoating contain PA1 (A) an amino-containing polymerization, polycondensation or polyaddition product as a binder which becomes water-dilutable on protonation with an acid, PA1 (B) a crosslinking agent and PA1 (C) from 0.05 to 10% by weight, based on components (A) and (B), of a monomeric organic complexing agent.
