Abstract

A water-based, low-emission latex paint formulation includes a vinyl acetate/ethylene (VAE) latex including a VAE resin with from 80 to 95 weight % vinyl acetate residue and from 5 to 20 weight % ethylene residue, optionally including additional monomers as well as a pigment composition including inorganic solids selected from inorganic pigments, inorganic fillers and mixtures thereof present in an amount such that the paint formulation has a pigment volume concentration (PVC) of from 25% to 85%. The formulations are suitable for eggshell and flat latex paints and exhibit surprising durability.
