Water reducible quaternary ammonium salt containing polymers

摘要

This invention relates to a water dispersible coating composition which comprises: (i) an acrylic polymer having active hydrogen functionality and quaternary ammonium salt functionality; and (ii) a blocked polyisocyanate. The water dispersible coating composition of this invention can be applied by any means known within the coatings art, but is especially suited for use in cathodic electrodeposition.
