Abstract: The present invention is directed to a curable, water-based coating composition utilized in waterborne coating systems. The coating composition is the reaction product of a water-dispersible cross-linking agent and a water-based copolymer prepared by free-radical polymerization. The copolymer is the reaction product of a first block and a second block. The first block is the reaction product of a plurality of monomers including ethylenically unsaturated monomers, acrylic acid and methyl methacrylate and vinylaromatic hydrocarbon monomers. One of the ethylenically unsaturated monomers includes a functional group suitable for reaction with the cross-linking agent. The second block is the reaction product of a non-functional, ethylenically unsaturated monomer. Methods for preparing the coating composition and a cured film are also disclosed.

Abstract: The present invention is directed to a curable, water-based coating composition utilized in waterborne coating systems. The coating composition is the reaction product of a water-based copolymer prepared by free-radical polymerization, and a cross-linking agent. The copolymer is the reaction product of a first block and a second block. The first block is the reaction product of a first ethylenically unsaturated monomer, acrylic acid, and a second ethylenically unsaturated monomer, methyl methacrylate, as well as the reaction product of a vinylaromatic hydrocarbon monomer, diphenylethylene. The second block is the reaction product of a plurality of ethylenically unsaturated monomers, styrene, 2-ethylhexyl methacrylate, cyclohexyl methacrylate, and carbonate-modified glycidyl methacrylate including a carbonate functional group that is subsequently converted into a carbamate functional group by ammonium hydroxie. The cross-linking agent, preferably a melamine, reacts with the carbamate functional group to establish a coating composition having urethane cross-linking from the carbamate- melamine reaction.

Abstract: The present invention is directed to a polyester carboxylate polymeric pigment dispersant to be used as a grind resin to incorporate inorganic pigment into a pigment dispersion for a coating composition. The polymeric pigment dispersant is the reaction product of pentaerythritol, hexahydrophthalic anhydride, glycidylneodecanoate, and dimethylethanolamine. The present invention is also directed to a method of preparing the polymeric pigment dispersant. In this method, the pentaerythritol 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 neutralizes the intermediate compound to form the completed polymeric pigment dispersant. The polymeric pigment dispersant is utilized for efficient wetting and grinding of the pigment.
