Abstract
It has been found that aqueous coating compositions comprising a blocked organic polyisocyanate, an amine adduct of an epoxy group-containing resin, and optionally a catalyst for urethane formation can be electrodeposited. These compositions deposit on the cathode to provide coatings having excellent properties.
