Abstract: The present invention relates to a composition comprising an aqueous dispersion of a) polymer particles having a z-average particle size in the range of from 50 nm to 500 nm; b) anion exchange resin particles having a D50 median particle size in the range of from 0.1 μm to 50 μm; and c) polymeric organic microspheres having a D50 median particle size in the range of from 1 μm to 20 μm, wherein the weight-to-weight ratio of polymer particles to microspheres is in the range of from 0.5:1 to 20:1. The composition of the present invention is useful for paint compositions that form matte finishes with an excellent balance of stain blocking and stain removal properties.

Abstract: The present invention relates to a composition comprising an aqueous dispersion of polymer particles; b) anion exchange resin particles; and c) an aminosilane. The composition achieves a more desirable balance of stain blocking and stain removal properties in pigmented coating formulations over compositions that contain the latex and the aminosilane but no anion exchange resin, or the latex and the ion exchange resin but no aminosilane.

Abstract: The present invention relates to opaque polymers functionalized with phosphorus acid groups, composites of TiO2 particles and the opaque polymers, and methods for their preparation. The composites are useful in coatings formulations and have been shown to exhibit improved hiding benefits in coated substrates over compositions containing non-functionalized opaque polymer and TiO2.

Abstract: The present invention relates to a latex composition comprising a) an opaque polymer having a pigment volume concentration of from 18 to 28; b) fully or partially polymer encapsulated TiO2 particles having a pigment volume concentration of from 8 to 18; c) an extender having a pigment volume concentration of from 0 to 10; d) a binder; e) a thickener; and f) water. Notwithstanding the surprisingly high pigment volume concentration of opaque polymer, the composition—upon application to a substrate—gives a coating with a gloss or semi-gloss finish, excellent hiding, and acceptable burnish resistance.
