Abstract:
1. A polymer dispersion comprising: a) an aqueous continuous phase; and b) dispersed particles of wherein the ratio of polyurethane to emulsion polymer is between 50:50 and 10:90; wherein the particles of the dispersion are in the form of multiphase particles comprising said polyurethane and said polymer; and wherein said dispersion is formed by emulsion polymerization of the monomers in the presence of a polyurethane dispersion, and wherein said polymer dispersion has a solids level of from 30 to 70 percent by weight, and wherein said emulsion copolymer or terpolymer further comprises from 0.5 to 10 percent by weight of the total monomers of at least one monomer having a functionality selected from the group consisting of aceto acetoxy, hydroxyl, and methylol functionalities, or a mixture thereof.
