ABSTRACT:
Self-crosslinking coating compositions which are cathodically deposited on electrodeposition of paints containing the coating compositions and a process for producing aqueous solutions of the self-crosslinking coating compositions by acid neutralization are described. The coating compositions are the reaction products of a resin carrying amine groups and hydroxyl or carboxyl groups, and the reaction product carrying one free isocyanate group of a polyisocyanate and at least one ethylenically unsaturated monomer having at least one isocyanate reactive hydrogen atom and the group ##STR1## The cathodically depositable electrodeposition paints cure rapidly at relatively low temperatures to provide films which are highly resistant to corrosive influences.
