Abstract: The present invention relates to a method for preparing a multiplicity of containers of paint from a plurality of vessels separately containing an aqueous solution of a rheology modifier, an aqueous dispersion of a colorant, an aqueous dispersion of polymer particles, and an aqueous dispersion of organic polymeric microspheres. In another embodiment, the present invention relates to a method of dispensing a colorant or an opacifying agent or an inorganic extender into separate containers partially filled with a waterborne pre-paint mixture of rheology modifier, polymer particles, and organic polymeric microspheres. The process of the present invention provides a simple and cost-effective way of preparing a wide variety of a large quantity of contained and finished paints at point-of-sale.

Abstract: The present invention is a composition comprising a blend of a PVA based latex and an EA/MMA based polyacrylic latex. The composition of the present invention is useful in a paint formulation for providing a coating with superior scrub resistance over a formulation comprising a blend of a PVA based latex and a BA/MMA based polyacrylic latex.

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 80 nm to 500 nm; b) polymeric crosslinked organic microspheres having a D50 particle size in the range of from 1 μm to 30 μm; c); a colorant and d) a zinc or zirconium compound. The composition of the present invention is useful for reducing leaching from a coating prepared from a deep base, low sheen paint formulation.
