Abstract
Synthetic resins which are water-dispersible Zwitterion-containing resins and containing chemically-bound quaternary ammonium base groups can be dissolved or dispersed in water to provide aqueous coating compositions. Such compositions in which these resins are the major resinous component can be applied by electrodeposition and deposit on the cathode to provide coatings of improved properties including a high degree of resistance to corrosion or staining.
