Disclosed are electrodepositable aqueous resinous dispersions that include a polymeric dispersant comprising an at least partially neutralized high molecular weight cationic acrylic polymer, and a cationic acrylic polymer that is different from the polymeric dispersant. Also disclosed are electrodepositable compositions comprising such a dispersion, electroconductive substrates at least partially coated with such compositions, methods for coating an electroconductive substrate with such compositions, and methods for making electrodepositable aqueous resinous dispersions. |
