Abstract
A pigment dispersant useful in cathodic electrocoat compositions is disclosed. The pigment dispersant is the reaction product of an organic monoepoxide or polyepoxide with a primary amine containing an imidazoline moiety. This pigment dispersant allows the maximazation of pigment to binder ratios and the minimization of volatile organic content (VOC) in electrocoat baths.
