Abstract: The present invention is an above-critical coating composition comprising an aqueous dispersion of polymer particles, pigment particles, and extender particles wherein the polymer particles comprise from 80 to 99.8 weight percent structural units of vinyl acetate and from 0.1 to 6 weight percent structural units of a phosphorus acid monomer. The composition shows surprisingly improved hiding with increased particle size of the polymer particles.

Abstract: The present invention is an above-critical coating composition comprising an aqueous dispersion of polymer particles, pigment particles, and extender particles wherein the polymer particles comprise, in a single phase and based on the weight of the polymer particles, from 35 to 79.9 weight percent structural units of vinyl acetate and from 0.1 to 6 weight percent structural units of a phosphorus acid monomer or a salt thereof, wherein the polymer particles have a particle size by dynamic light scattering of from 250 nm to 500 nm. The above-critical composition shows surprising improvements in hiding with increasing particle size of the polymer particles.
