The present invention relates to a composition comprising an aqueous dispersion having: an associative thickener having a hydrophobic portion having a calculated log P in the range of 2.7 to 5.0; and composite particles , which comprises phosphoric acid-functionalized polymer particles adsorbed to the surface of TiO2 particles; wherein the phosphoric acid-functionalized polymer particles have a core-shell morphology, wherein the core protrudes from the shell. The compositions of the present invention provide the formulator with flexibility in using low shear rate thickeners and medium shear rate thickeners to balance paint performance. |
