Abstract
An electrodeposition process using an aqueous coating composition comprising a carbamate-functional crosslinking agent and at least one principal resin is described. The carbamate-functional crosslinker is formed by first reacting a polyamine having at least two primary amine groups and at least one secondary amine group with a cyclic carbonate, and then reacting the product of the first reaction with a polyepoxide compound.
