Novel coating compositions are disclosed which comprise aqueous dispersions of polyamine resins in the form of their acid salts along with azetidinedione crosslinking agents and other optional adjuvants. The compositions give rise to improved methods for the electrodeposition of heat-curable films on substrates. The compositions and methods find particular utility in the cathodic deposition of coatings and films on automotive parts and household appliances.

Described are compounds characterized by the following formula: ##STR1## wherein C. sub. n H. sub. 2n is alkylene from 2 to 12 carbon atoms and C. sub. m H. sub. 2m is alkylene from 2 to 20 carbon atoms. Each of the alkylene groups can, optionally, be substituted by inert substituents. The compounds contain a free isocyanato group and a masked isocyanate group, namely, the cyclic urea moiety, which, when the compounds are heated, preferably in the presence of a catalyst, opens to give the group OCN--C. sub. n H. sub. 2n --. Thus, the compounds can be reacted via the free isocyanate group with active hydrogen-containing monomers or polymers to form storage stable compositions which, upon heating, are curable via reaction with the cyclic urea group.
