Abstract: An acrylic composition includes the reaction product of an acrylic polymer, a carbamate having anhydride-reactive functionality and carbamate functionality, and a carboxylic acid anhydride that is reactive with the carbamate to form a carboxylic acid carbamate. The acrylic polymer includes the reaction product of a functionalized monomer, a first compound reactive with the functionalized monomer to form a functionalized intermediate, and a highly branched, polyfunctional core molecule reactive with the functionalized intermediate. The first compound includes vinyl functionality reactive with the functionalized monomer and epoxy functionality. The carboxylic acid carbamate has the carbamate functionality and carboxylic acid functionality that is reactive with the acrylic polymer. The acrylic composition is highly-branched and, when used in coating compositions in combination with a suitable cross-linking agent, enhances recoat adhesion and produces cured films that have optimum scratch, mar, and chip performance, and acid etch resistance.

Abstract: The present invention is directed to a polymeric pigment dispersant to be used as a grind resin to incorporate pigment into a pigment dispersion for a coating composition. The polymeric pigment dispersant is the reaction product of dipentaerylthritol, hexahydrophthalic anhydride, glycidylneodecanoate, dimethylethanolamine, and polyphosphoric acid. The present invention is also directed to a method of preparing the polymeric pigment dispersant. In this method, the dipentaerythritol and the hexahydrophthalic anhydride are polymerized to form an intermediate compound. Next, an epoxy group of the glycidylneodecanoate reacts with the intermediate compound, and then the dimethylethanolamine salts the intermediate compound. Finally, the polyphosphoric acid is added to form the completed polymeric pigment dispersant. The polymeric pigment dispersant has improved stability in the pigment dispersion and is utilized for efficient wetting and grinding of the pigment in the pigment dispersion.
