ABSTRACT:
Electrodepositable coating compositions comprising an active hydrogen-containing ionic resin and a curing agent which contains blocked isocyanate groups and oxazolidone groups are disclosed. These coating compositions reduce the tendency of cured electrodeposited films to cause yellowing in subsequently applied topcoat systems. The use of these electrodepositable coating compositions in the process of electrodeposition is also disclosed.
