-14. (canceled)
A water-borne polymer emulsion comprises:
- (A) a copolymer prepared by polymerization of at least one hydrophobic monoethylenically unsaturated monomer (a), hydrophilic monoethylenically unsaturated monomer (b), and at least one functional monomer (c);
- wherein the functional monomer (c) is selected from the group consisting of an ethylenically unsaturated monomer having an acid group and/or the corresponding anion thereof, an ethylenically unsaturated monomer having an amino, amido, ureido, 1,3-diketo group, hydroxyl, polyether chain, or N-heterocyclic group and/or protonated on the nitrogen, or alkylated ammonium derivatives thereof;
- wherein the functional monomer (c) is different from monomer (a) and monomer (b);
- and
- (B) an emulsifier system, wherein the emulsifier system comprises at least one phosphate emulsifier.
