Patent ID: 8791190

Claim:
A one component aqueous composition comprising (i) a cationic stain blocking polymer chosen from 0.01 to 7 wt. %, based on the total weight of solids in the composition, of anion exchange resin copolymer beads that have a weight average particle size of from 0.1 to 20 μm and have a copolymerized crosslinker content of from 0.5 to 2.0 wt. %, based on the total weight of monomers used to make the anion exchange resin copolymer, from 1 to 30 wt. %, based on the total weight of solids in the composition of a crosslinked cationic addition polymer which has from 20 wt. % to 96 wt. %, based on the total weight of monomers used to make the copolymer, of the copolymerized residue of a monomer chosen from a cationic monomer, a monomer that is modified to contain a cation and mixtures thereof, from 4 to 30 wt. % of a crosslinking monomer, and the remainder of an one or more other monoethylenically unsaturated monomer, and mixtures thereof, (ii) one or more emulsion copolymer having a copolymerized residue of at least one phosphorus acid monomer and having an anionic surfactant or its polymerization residue and a reductant or its polymerization residue, and (iii) a stabilizer of from 0.1 to 2 wt. %, based on the total weight of emulsion copolymer solids, of an inorganic phosphorus containing dispersant, and from 0.2 to 5.0 wt. %, based on the total weight of emulsion copolymer solids, of a mixture of a nonionic surfactant and an anionic surfactant, wherein when the cationic stain blocking polymer is an anion exchange resin bead it is chosen from gelular beads, beads having a dual morphology, and mixtures thereof.
