Abstract
The present invention is directed to an electrodepositable coating composition comprising an acrylic polymer comprising greater than 60% by weight of constitutional units comprising the residue of a hydroxyl-functional (meth)acrylate monomer and/or a hydroxyl-functional (meth)acrylamide monomer, based on the total weight of the acrylic polymer; and an ionic salt group-containing film-forming polymer different from the acrylic polymer. Also disclosed are coatings, coated substrates, and methods of coating a substrate.
