Claim:
1. A composition comprising an aqueous dispersion of a) from 0.02 to 2 weight percent, based on the weight of the composition, of an associative thickener having a hydrophobic portion with a calculated log P in the range of from 2.7 to 4.8; and b) from 5 to 60 weight percent, based on the weight of the composition, of composite particles comprising phosphorus acid functionalized polymer particles adsorbed to the surfaces of TiO 2 particles; wherein the volume solids content of the composition is in the range of from 30 to 44 volume percent, with the proviso that when the volume solids content is in the range of from 30 to 36 volume percent, the calculated log P of the hydrophobic portion of the associative thickener is in the range of from 4.0 to 4.8.
