ABSTRACT:
A pigment dispersant that is useful in a cathodic electrocoating composition is prepared by bringing into contact compound (i), an alkylene carbonate, with a compound (ii) of the structure: ##STR1## where R is and alkyl group having 8-24 carbon atoms, and bringing the resulting reaction product of (i) and (ii) into contact with a half blocked organic diisocyanate; this pigment dispersant has an advantage of allowing for the maximization of pigment to binder ratios and the minimization of volatile organic content (VOC) in electrocoating compositions.
