Abstract:
The present invention relates to coating compositions formed by combining two latex resins: a base latex resin and a stratifying latex resin. The stratifying latex resin comprises at least one “driver” to promote migration of the stratifying latex to the surface of the coating during curing or drying. Drivers may be selected from one or more of fluorine containing monomers incorporated into the stratifying latex, long chain acrylate monomers, such as lauryl methacrylate, wax, small particle size, or relatively low Tg.
