Abstract:
A method of making a multilayer electrodeposited composition, comprising,applying a first coating composition by electrophoretic deposition to a substrate to make a coated substrate,subjecting the coated substrate to an amount of energy effective to cause the coated substrate to become a conductive coated substrate,applying a second coating composition to the conductive coated substrate by electrophoretic deposition to make a multicoated substrate, andsubjecting the multicoated substrate to conditions sufficient to result in the cure of the second coating composition so as to make a cured multicoated substrate,wherein the second coating composition comprisesa cathodic electrocoat coating composition comprising an aqueous dispersion of a polymer (a) having a plurality of carbamate functional groups, said polymer represented by randomly repeating units according to the formula: ##STR10##R.sub.1 represents H or CH.sub.3,R.sub.2 represents H, alkyl, or cycloalkyl,L represents a divalent linking group,A represents repeat units comprising at least one repeat unit having a pendentcationic salting site,x represents 10 to 90 weight %, andy represents 90 to 10 weight %.
