ABSTRACT:
A composition suitable for use as a coating composition depositable by cationic electrodeposition which has improved edge protection capability containing, in addition to the conventional ingredients used in compositions for cationic electrocoat, such as an aqueous cationic resin, micro-resin particles of a size sufficient to be water dispersible which particles comprise an internally crosslinked polymer of (A) an active hydrogen containing monomer and (B) a monomer containing at least two active double bonds, which polymer further contains a cationic group in sufficient proportion to allow the micro-resin particle to be water dispersed.
