Abstract: A waterbased coating composition containing about 10-30% by weight of film forming binder dispersed in an aqueous carrier; wherein the binder contains abouta. 20-85% by weight, based on the weight of the binder, of a methylol (meth)acrylamide carboxyl containing acrylic polymer and the carboxyl groups of the polymer are reacted with ammonia or amine to provide a pH to the composition of about 7.0-10.0;b. 10-40% by weight, based on the weight of the binder, of a polyurethane which is either a polyester urethane, polyether urethane or polyacrylourethane;c. 5-40% by weight, based on the weight of the binder of a water-soluble or a water-dispersible alkylated melamine formaldehyde crosslinking agent of a polymeric partially methylated melamine formaldehyde resin having a degree of polymerization of about 1-3;the composition forms an automotive quality clear coat and/or pigmented color coat for automobiles and trucks; and the acrylic polymer can be used to form an automotive quality primer composition.
