Abstract
Disclosed are electrodepositable coating compositions that include a cationic amine salt group-containing (meth)acrylic polymer in which the (meth)acrylic polymer is prepared by polymerizing a mixture of ethylenically unsaturated monomers comprising at least 10% by weight of a (meth)acrylic monomer containing hydroxy ester groups, the % by weight being based on total weight of ethylenically unsaturated monomers, and an acid salt of a guanidine or a guanidine reaction product. Associated methods of preparing an amine salt group containing composition and for coating a substrate are also disclosed. Substrates coated with the electrodepositable coating composition are also disclosed.
