Abstract:
The present invention relates to a composition comprising a stable aqueous dispersion of large acrylic based polymer particles and small acrylic based polymer particles wherein the large polymer particles comprise structural units of a phosphorus acid monomer or a salt thereof; and wherein the small polymer particles comprise a substantial absence of structural units of any phosphorus acid monomer and salts thereof. The bimodal dispersion of the present invention provides a way of making a high solids adsorbing latex with high hiding efficiency.
