  • Patent number: 8362132
    Abstract: Aqueous coating composition having a PVC from 78 to 85% and free of non-fugitive coalescing solvent, comprising, based on the total volume solids of the dry coating unless otherwise stated, a) opacifying pigment particles comprising from 3 to 10% titanium dioxide and from 0 to 20% of hollow polymeric particles; b) non-opacifying extender particles comprising calcium magnesium carbonate and/or calcium carbonate and/or nepheline syenite and/or kaolin; c) polymer binder particles of calculated Fox Tg of from 5 to 25° C. having an acid value of from 15 to 65 mg KOH/g of polymer; d) dispersant having weight average molecular weight of at least 3500 Daltons, and wherein the dispersant demand of a mixture of the opacifying pigment particles, other than the hollow polymeric particles, of a) and the extender particles of b) is greater than 0.35 wt %, calculated on the weight of the titanium dioxide and extender particles; e) fugitive coalescing solvent.
