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.
