Abstract
The present invention is directed to an electrodepositable coating composition comprising an acrylic polymer comprising a polymerization product of a polymeric dispersant and an aqueous dispersion of a second-stage ethylenically unsaturated monomer composition comprising greater than 40% by weight of a second-stage hydroxyl-functional (meth)acrylate monomer, based on the total weight of the second-stage ethylenically unsaturated monomer composition; an ionic salt group-containing film-forming polymer different from the acrylic polymer; and a curing agent. Also disclosed are coatings, coated substrates, and methods of coating a substrate.
