Abstract

An aqueous coating composition contains: (a) from 50% to 90%, by weight based on the weight of the aqueous coating composition, of a film-forming polymer; (b) from 4% to 90%, by weight based on the weight of the film-forming polymer, of an oligomer having a weight average molecular weight of less than 15,000 g/mol; where the oligomer comprises, by weight based on the weight of the oligomer, from 1% to 20% of structural units of an acid monomer, a salt thereof, or mixtures thereof; from zero to 20% of structural units of a monoethylenically unsaturated functional monomer carrying at least one of functional groups selected from an amide, carbonyl, ureido, silane, hydroxy, or amino group, or combinations thereof; from 30% to 99% of structural units of a hydrophilic monoethylenically unsaturated nonionic monomer; and from zero to 30% of structural units of a hydrophobic monoethylenically unsaturated nonionic monomer; and (c) from 4% to 15%, by weight based on the weight of the aqueous coating composition, of a specific silicone polyether copolymer.
