A waterbased coating composition containing about 10-30% by weight of film forming binder dispersed in an aqueous carrier; wherein the binder contains about a. 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.

A waterbased coating composition formed of an acrylic latex and an acrylic hydrosol dispersed in an aqueous carrier and has a pH of about 7-10; wherein the binder is a blend of an acrylic latex polymer having a particle size of about 0. 06-0. 20 microns and an acrylic hydrosol polymer having a particle size of less than 0. 30 microns; wherein the blend contains a. a methylol (meth)acrylamide carboxyl containing acrylic latex polymer of polymerized monomers of alkyl methacrylate, alkyl acrylate or mixtures thereof, 1-15% by weight of methylol methacrylamide, methylol acrylamide or mixtures thereof, 0. 5-10% by weight of ethylenically unsaturated carboxylic acid having reactive carboxyl groups, 0. 5-10% by weight of ethylenically unsaturated hydroxyl and the carboxyl groups of the polymer are reacted with ammonia or an amine; b. an acrylic hydrosol polymer of methylol (meth)acrylamide acrylic polymer containing carboxyl and hydroxyl groups about 0.
