Abstract
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.
