Claim Text:
1. An aqueous coating composition comprising a binder, the binder comprising a cathodically electrodepositable, acid-salted, amine-functional phosphorylated resin and a second amine-functional resin selected from the group consisting of epoxy resins, polyesters, polyurethanes, vinyl resins, and polybutadiene resins, wherein the cathodically electrodepositable, acid-salted, amine-functional phosphorylated resin is prepared by a phosphorylating reaction and wherein the cathodically electrodepositable, acid-salted, amine-functional phosphorylated resin has at least one amine group introduced before or after the phosphorylating reaction, wherein the acid comprises a member selected from the group consisting of phosphoric acid, phosphonic acid, propionic acid, formic acid, acetic acid, lactic acid, and citric acid; wherein the cathodically electrodepositable, acid-salted, amine-functional phosphorylated resin comprises a monophosphate ester group, a monophosphonic acid ester group, or both.
