Summary: | An aqueous resin dispersion containing as an aqueous resin component a polyurethane-modified epoxy-polyamine resin comprising a reaction product of an epoxy group-containing polyurethane compound obtained by the reaction of a polyhydroxy compound having a number average molecular weight of 50 to 8,000, a polyisocyanate compound, and a compound containing one hydroxyl group and at least one alicyclic epoxy group in a molecule; a bisphenol compound; a bisphenol diglycidyl ether compound; and an active hydrogen-containing amine compound. Said aqueous resin dispersion has excellent corrosion resistance and is suited especially for cathode electrodeposition coating. |
