The invention relates to acrylic emulsion comprising between 0.1 and 10% of at least one fluoromonomer, at least one polymerizable phosphate functional monomer, and at least one wet adhesion monomer. The combination of the fluoromonomer with a polymerizable phosphate functional monomer and wet adhesion adhesion monomer act together to greatly improve the stain resistance of the acrylic emulsion.
