Abstract:
1. An aqueous coating composition comprising: (1) a base latex resin; and (2) a stratifying latex resin having latent crosslinking functionality, the stratifying latex comprising the polymerization reaction product of at least one or more copolymerizable monoethylenically unsaturated monomers, wherein the monoethylenically unsaturated monomers comprise (a) at least one fluorine containing monomer and (b) at least one monomer having latent crosslinking functionality, wherein the stratifying latex resin is a two-stage polymer formed by sequentially polymerizing a first group of monomers to form a core and a second group of monomers to form a shell, and wherein the core has a Tg from about −20° C. to about 10° C. and comprises the polymerization reaction product of a fluorine containing monomer, a monomer having latent crosslinking functionality; and a long chain acrylate monomer having an alkyl length of at least 12, and wherein the shell has a Tg from about 35° C. to about 100° C. and comprises the polymerization reaction product of one or more copolymerizable monoethylenically unsaturated monomers excluding fluorine containing monomers.
