Abstract
Abstract Aqueous coating compositions, such as paints, are provided which have improved stain resistance with resulting improved cleanability. The coating compositions comprise aqueous dispersions of water-insoluble polymeric binders having about 0.5 to 10% by weight of ethylenically unsaturated acid monomer units and about 0.2 to 10% by weight of solids of selected thickeners used with about 0.01 to 5% by weight of solids of a fluorocarbon compound containing one or more segments having at least one water-solvatable polar group of water solubility and one or more segments having fluorinated carbon atoms terminated by trifluoromethyl groups for aiding in stain resistance in combination with the selected thickeners.
