The present invention relates to a composition comprising a bimorphological aqueous dispersion of first and second polymer particles, wherein the first polymer particles comprise a shell and a phosphorus acid functionalized protuberating core, and the second polymer particles do not comprise a protuberating core. The composition is useful for pigmented coatings formulations.

Bimorphological latex

The present invention relates to a composition comprising an aqueous dispersion of an associative thickener having a hydrophobic portion with a calculated log P in the range of from 2.7 to 5.0; and composite particles comprising phosphorus acid functionalized polymer particles adsorbed to the surfaces of TiOparticles; wherein the phosphorus acid functionalized polymer particles have a core-shell morphology wherein the core protuberates from the shell. The composition of the present invention provides formulators with flexibility in their use of low and mid shear rate thickeners to balance paint performance properties.

Pigmented paint formulation with a phosphorus acid functionalized latex binder and an associative thickener

The present invention relates to a composition comprising an aqueous dispersion of an associative thickener having a hydrophobic portion with a calculated log P in the range of from 2.7 to 4.8; and composite particles comprising phosphorus acid functionalized polymer particles adsorbed to the surfaces of TiOparticles. The composition of the present invention provides formulators with flexibility in their use of low and mid shear rate thickeners to balance paint performance properties.

The present invention relates to a coatings composition comprising an aqueous dispersion of polymer particles, pigment particles, and extender particles. The polymer particles comprise from 35 to 99.8 weight percent structural units of vinyl acetate and from 0.1 to 6 weight percent structural units of a phosphorus acid monomer or a salt thereof, and the coating composition has a pigment volume concentration in the range of from 25 up to the critical pigment volume concentration of the composition.
