Abstract
Ungelled resins, aqueous dispersions of cationic resins, coating compositions, and electrodeposition using the resinous coating compositions are disclosed. The resins are formed from reacting polyepoxides with polyoxyalkylenepolyamines. The aqueous dispersions are prepared by at least partially neutralizing the resins to provide cationic groups and dispersing the cationic resins in aqueous medium. When added to cationic electrodepositable coating compositions, such as high throwpower compositions, the ungelled cationic resins provide better appearing, more flexible and water-resistant electrodeposited coatings.
