ABSTRACT:
An aqueous, cationically electrodepositable coating composition contains a ternary sulfonium or quaternary phosphonium group containing resin, an aminoplast or phenoplast crosslinking agent and a catalytic amount of a non-ionic ester of a sulfonic acid as latent acid catalyst to catalyze the reaction between the sulfonium or phosphonium group containing resin and the aminoplast crosslinking agent.
