Abstract
This invention relates to a latex composition particularly suited as a paint vehicle for the manufacture of semi-gloss and flat interior paint compositions. The latex composition comprises from about 40 to 70% by weight of copolymer resin particles having at least 50% vinyl acetate polymerized therein, the particles being substantially spherical and characterized in that not more than 5% of the particles have a size greater than 0.65 microns and not more than 5% have a particle size less than 0.33 microns. In the preferred instance, the resin particles comprise vinyl acetate, a lower alkyl acrylate and a conventional wet adhesion monomer, the combination consisting of from about 80 to 90% vinyl acetate, 10 to 20% of lower alkyl acrylate, e.g., butyl acrylate and 0.2 to 1.5% of the wet adhesion monomer.
