ABSTRACT:
An electrodepositable composition is provided comprising: (a) active hydrogen-containing, cationic salt group-containing resin electrodepositable on a cathode; (b) at least one at least partially capped polyisocyanate curing agent; (c) at least one metal-containing catalyst; and (d) at least one material having the following general formula: ##STR1## wherein R.sub.1 is alkyl or substituted alkyl having 1 to 18 carbon atoms or aryl or substituted aryl; and R.sub.2 is hydrogen, alkyl or substituted alkyl having 1 to 18 carbon atoms or aryl or substituted aryl. The composition can demonstrate enhanced corrosion resistance at low metal catalyst levels without loss of cured film properties or appearance when electrodeposited and cured over conductive substrates.
