Title WATERBASED COATING COMPOSITION OF METHYLOL (METH)ACRYLAMIDE ACRYLIC POLYMER, ACRYLIC HYDROSOL AND MELAMINE CROSSLINKING AGENT ABSTRACT 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 0.5-10% by weight of an ethylenically unsaturated carboxylic acid, 0.5-10% by weight of ethylenically unsaturated hydroxyl and the carboxyl groups of the polymer are reacted with ammonia or an amine and c. an alkylated melamine formaldehyde crosslinking agent and the composition forms an automotive quality clear coat and/or pigmented color coat.
