Abstract:
A cathodic electrodeposition method, comprising1) immersing a conductive substrate in a coating composition comprising, in an aqueous medium:(a) a polymer backbone having appended thereto at least one carbamate functional group, said first component represented by randomly repeating units according to the formula: ##STR8## 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 pendent cationic salting site which is salted with an acid,x represents 10 to 90 weight %, andy represents 90 to 10 weight %, and(b) a compound having a plurality of functional groups that are reactive with said carbamate groups,2) applying a voltage between an anode and the conductive substrate, and3) removing the substrate from the coating composition.
