Abstract

Aqueous synthetic resin dispersions comprising (A) an ionic resin, based on aralkylated epoxy resins, (B) a blocked polyisocyanate and (C) a polymer of at least one olefinically unsaturated monomer which is capable of undergoing free-radical polymerization are useful, for example, as binders in processes of coating by electrodeposition.
