Aqueous dispersion of opacifying pigment particles and colorant

A composition comprising an aqueous dispersion of

• 1) multistage polymer particles comprising:
• a) a water-occluded core comprising from 20 to 60 weight percent structural units of a salt of a carboxylic acid monomer and from 40 to 80 weight percent structural units of a nonionic monoethylenically unsaturated monomer;
• b) a polymeric shell having a Tg in the range of from 60° C. and 120° C.;
• and
• c) a polymeric binder layer superposing the shell, which polymeric binder layer has a Tg of not greater than 35° C. and comprises structural units of at least one monoethylenically unsaturated monomer;
• wherein the weight-to-weight ratio of structural units of monomers in the water-occluded core to the shell in the multistage polymer particles is in the range of 1:10 to 1:20;
• the weight-to-weight ratio of the polymer binder to the sum of the shell and the structural units of monomers in the core in the multistage polymer particles is in the range of 1:1 to 3.5:1;
• and
• the z-average particle size of the multistage polymer particles is in the range of from 300 nm to 750 nm;
• 2) from 0.01 to 0.05 weight percent, based on the weight of the composition, of a colorant that absorbs light in the range of from 500 nm to 600 nm, and
• 3) an opacifying inorganic pigment having a pigment volume concentration in the range of from 25% to 40%.
