Abstract
Aqueous coating compositions are described where the binder includes an anionically stabilized polymeric dispersion. The monomers used to prepare the dispersion are acrylic acid and methacrylic acid as a carboxylic monomer and styrene, alpha methyl styrene or vinyl toluene as a hydrophobic high Tg aromatic monomer and an alkyl acrylate ester as a low Tg monomer. The relative weight proportions of the monomers are required to satisfy a formula. Blends of high and low Tg dispersions are also described. Paints formulated with the binders exhibit an excellent balance of stain resistance, tint strength and viscosity stability.
