    • 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 C8-C30 alkanols, 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.
    • 本发明涉及包含至少一种聚合物(P)的聚合物分散体(PD)的用途,所述聚合物(P)可通过至少一种烯属不饱和单体(M1)和至少一种不同于其的烯属不饱和单体(M2)的自由基乳液聚合而获得 并选自膦酸或磷酸与未烷氧基化或烷氧基化羟基烷基(甲基)丙烯酸酯的酯,和至少一种选自具有非烷氧基化或烷氧基化的C 8 -C 30链烷醇的磷酸酯及其盐的乳化剂(E) 提高由其制备的涂料的耐擦洗性和/或提高由其制备的涂料的耐光泽性和/或改善由其制备的涂料的耐污染性和/或改善由其制备的涂料中的颜料分布和/ 或者通过由其制备的涂层来减少挥发性有机化合物的排放,以减少根据本发明使用的聚合物分散体 d涂覆包含本发明聚合物分散体的材料。
