Claim Text:
1. A composition comprising a) a stable aqueous dispersion of polymer particles functionalized with structural units of a phosphorus acid monomer or a salt thereof and; b) a dispersion of pigment particles stabilized by an adsorbing water-soluble dispersant functionalized with structural units of a sulfonic acid monomer or a salt thereof; wherein the weight percent of the dispersant is from 0.1 to 10 percent, based on the weights of the dispersant and pigment particles; wherein the weight percent of pigment particles is from 20 to 95 weight percent based on the weight of the polymer particles, the pigment particles, and the dispersant; and wherein the weight percent of structural units of phosphorus acid monomer or a salt thereof is from 0.1 to 5 weight percent, based on the weight of the phosphorus acid functionalized polymer particles.
