Abstract
The present invention relates to the use of a polymer dispersion (PD) comprising at least one polymer (P), obtainable by free-radical emulsion polymerization of at least one ethylenically unsaturated monomer (M1) and at least one monomer (M2) different therefrom and selected from esters of phosphonic acid or of phosphoric acid with unalkoxylated or alkoxylated hydroxyalkyl(meth)acrylates, and at least one emulsifier (E) selected from phosphoric esters with unalkoxylated or alkoxylated C-Calkanols, and their salts, in coating materials to improve the scrub resistance of the coatings produced therefrom and/or to improve the burnish resistance of the coatings produced therefrom and/or to improve the stain resistance of the coatings produced therefrom and/or to improve the pigment distribution in the coatings produced therefrom and/or to reduce the emission of volatile organic compounds by the coatings produced therefrom, to polymer dispersions used in accordance with the invention, and to coating materials comprising the polymer dispersions of the invention.
