摘要：
The present invention is directed to a polyester polycarbamate polymeric pigment dispersant to be used as a grind resin to incorporate pigment into pigment dispersions for coating compositions. The pigment dispersant is the reaction product of a first compound having a plurality of hydroxyl groups, a carboxylic acid anhydride, a second compound having at least one epoxy group, and a carbamate compound. The present invention is also directed to a method of preparing the pigment dispersant.
