Abstract
An aqueous coating composition includes, based on the total weight of the aqueous coating composition, (a) an aqueous polymer dispersion present in an amount of from 15% to 33% by solids weight, wherein the polymer includes at least 95% by solids weight of an acrylic emulsion copolymer based on the solids weight of the polymer; (b) anionic colloidal silica present in an amount of from 1% to 13% by solids weight; (c) a solvent present in an amount of from 0.5% to 9% by weight, wherein the solvent has at least one hydroxyl group and a dielectric constant at 25° C. of from 7 to 10.3; (d) a monoamine compound present in an amount of from 0.2% to 1.5% by weight, wherein the monoamine compound is selected from an alkyl monoamine, a beta-hydroxyl monoamine containing up to 2 hydroxyl groups, or mixtures thereof; and (e) water.
