Abstract
Water-dilutable polyurethane/acrylic copolymers which may be either completely nonionically stabilized or partically nonionically and partically anionically stabilized comprise the reaction product of an ethylenically terminated polyurethane macromonomer containing poly(oxyalklyene) segments and one or more ethylencially unsaturated monomers selected from acrylic acid, methacruylic acid, fumaric acid, styrene, vintyltoluene, and alkyl and hydroxyalkyl esters of acrylic, methacrylic, and furamic acids. The copolymers are useful as principal resins and as pigment grind resins in water-borne automotive base coat paint formulations.
