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.
