Abstract
An electrocoating composition containing a polymer having pendant amine groups, an alpha-, beta-ethylenically unsaturated carbonyl cross-linking agent, and an ultraviolet photosensitizer can be electrodeposited onto a cathode substrate disposed within an aqueous electrocoating bath. The amine groups of the polymer are protonated to render the polymer water dispersible prior to electrodeposition and upon electrodeposition the amine groups become de-protonated. The cross-linking agent cross-links the polymer upon ultraviolet irradiation of the electrocoated cathode substrate to form a fully-cured electrodeposited coating on the cathode substrate.
