Abstract
Official abstract text for this publication.
The present invention relates to a coatings composition comprising an aqueous dispersion of polymer particles, pigment particles, and extender particles. The polymer particles comprise from 35 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 or a salt thereof, and the coating composition has a pigment volume concentration in the range of from 25 up to the critical pigment volume concentration of the composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A 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, at least 35 weight percent structural units of vinyl acetate, from 10 to 64.8 weight percent structural units of ethyl acrylate, 2-ethylhexyl acrylate, or butyl acrylate or a combination thereof; from 0.1 to 2.0 weight percent str…
