摘要： The present invention relates to a stable aqueous pigment dispersion including: an aqueous medium, pigment particles, and from 0.1% to 15%, by weight based on the weight of pigment, of a dispersant, the dispersant including: (1) a first water-soluble polymer having an acid number of from 0 to 80 and a calculated Mn of from 450 Daltons to 10,000 Daltons; and 2) a second water-soluble polymer comprising, as copolymerized units, from 30% to 100% by weight, based on the weight of the second polymer sulfonic acid monomer, or a salt thereof, and from 0% to 10% by weight, based on the weight of the second polymer, carboxylic acid monomer, or a salt thereof; wherein the second polymer has a calculated Mn of from 1000 to 25,000 Daltons; wherein the dispersant comprises a proportion of the first polymer to the second polymer of from 0.1:1 to 10:1 on a solids basis, and the first polymer and the second polymer are miscible in those proportions; and wherein the dispersant is substantially free of structural units of phosphorus acid monomers and their salts. The invention also relates to a method for forming the stable aqueous dispersion and a dry coating formed from the aqueous dispersion. The stable aqueous dispersion is useful, inter alia, for forming certain composite particles.
