1. An electrodepositable coating composition comprising:
(a) an active hydrogen-containing cationic salt group-containing polymer; and (b) 0.1 to 20 percent by weight, based on the total weight of resin solids in the coating composition, of a cationic salt group-containing ungelled acrylic polymer, different from (a), that comprises a reaction product of an ethylenically unsaturated monomer composition comprising:
(i) a hydroxy-functional ethylenically unsaturated monomer;(ii) at least 10 percent by weight, based on the total weight of the ethylenically unsaturated monomer composition, of an amine-functional ethylenically unsaturated monomer;(iii) 10 to 40 percent by weight, based on the total weight of the ethylenically unsaturated monomer composition, of an alkyl(meth)acrylate having at least 8 carbon atoms in the alkyl group; and at least one of:(iv) 1 to 20 percent by weight, based on the total weight of the ethylenically unsaturated monomer composition, of an alkyl(meth)acrylate having less than 8 carbon atoms in the alkyl group, and(v) 1 to 30 percent by weight, based on the total weight of the ethylenically unsaturated monomer composition, of a vinyl aromatic monomer. |
