Abstract

Solvent-free aqueous synthetic-resin dispersions comprising a polymer (A) which is obtained by polymerization of (A1) capped polyisocyanates in which some of the capping groups contain an ethylenically unsaturated group, and (A2) ethylenically unsaturated monomers in the presence of an ionic resin (B). The resin is useful in electrodeposition coatings.
