    • A coating composition comprises at least one material dispersed in a vinyl or acrylic polymer, wherein the vinyl or acrylic polymer comprises (a) one or more anchor group monomer units (a) having an ionizable or active hydrogen functionality or a functionality that forms a covalent bond with the dispersed material, wherein the ionizable functionality is other than a carboxylic acid group in which the carbonyl carbon is separated from the closest ethylenically unsaturated carbon by at least four atoms and the anchor group monomer units (a) are other than those having polyoxyalkylene groups; (b) about 5% to about 45% by weight of one or more stabilizer monomer units (b) having a carboxylic acid group in which the carbonyl carbon is separated from the closest ethylenically unsaturated carbon by at least four atoms, having polyoxyalkylene groups, having gamma-hydroxy carbamate or beta-hydroxy carbamate groups, and combinations thereof; and (c) up to about 50 percent by weight of aromatic monomer units.
