ABSTRACT:
A pigment dispersant that is useful in a cathodic electrocoating composition is prepared by bringing into contact the following compounds: a cyclic alkylene urea amine, a polyepoxide and a dialkanol amine; this pigment dispersant has an advantage of allowing for the high pigment to binder ratios and minimizes the volatile organic content (VOC) in the electrocoating composition.
