Abstract

A pigmented latex composition having a solids content in a range from 60 wt % to 95 wt % includes

a) an aqueous dispersion of a polymeric binder that is a copolymer including units of vinyl acetate, ethylene and at least one ethylenically unsaturated carboxylic acid or salt thereof, the polymeric binder constituting in a range from 10 wt % to 30 wt % of the composition; wherein vinyl acetate units constitute in a range of 70-95 wt % of the polymeric binder, ethylene units constitute in a range of 5-30 wt % of the polymeric binder and ethylenically unsaturated carboxylic acid units constitute in a range from 0.75 wt % to 5 wt % of the polymeric binder;the aqueous dispersion of the polymeric binder is free of alkylphenol ethoxylate surfactants and phosphate ester surfactants; andthe polymeric binder has a weight average particle size in a range from 0.1 μm to 0.3 μm; b) one or more pigments constituting in a range from 30 wt % to 50 wt % of the composition, selected from the group consisting of polymeric pigments, aluminosilicates, calcium carbonate, titanium dioxide, talc, barium sulfate, zinc oxide, aluminum trihydrate, amorphous silica and silicates;c) one or more plasticizers; andd) one or more pigment dispersants.
