    Abstract: The present invention relates to latex paints, which contain a) a multistage carboxylated polymer latex binder obtainable by multistage aqueous emulsion polymerisation of a monomer composition M consisting of at least one non-ionic monomer M1, which is selected from C1-C20-alkyl esters of acrylic acid, C1-C20-alkylesters of methacrylic acid, and vinyl aromatic monomers; one or more monoethylenically unsaturated monomers M2, which are selected from monoethylenically unsaturated monocarboxylic acids having 3 to 6 carbon atoms and monoethylenically unsaturated dicarboxylic acids having 4 to 6 carbon atoms, and optionally one or more non-ionic monomers M3, which are different from monomers M1; where in at least one stage, the relative amount of monomers M2 added in this stage is at least 6% by weight, based on the total amount of monomers added in said stage, the total amount of monomers M2 being from 0.05 to 5% by weight, based on the total amount of the monomer composition M; b) a titanium dioxide pigment; c) a polymeric dispersant PD which is selected from homo and copolymers of monomers M4, which are selected from monoethylenically unsaturated monocarboxylic acids having 3 to 6 carbon atoms and monoethylenically unsaturated dicarboxylic acids having 4 to 6 carbon atoms, where the monomers M4 make up at least 85% of the monomers forming the polymeric dispersant; and d) an associative thickener polymer.

    Abstract: Una pintura de látex que contiene: a) un aglutinante de látex de polímero carboxilado de múltiples etapas que puede ser obtenido por medio de la polimerización en emulsión acuosa de múltiples etapas de una composición de monómero M que consiste en - al menos un monómero no iónico M1, que es seleccionado entre ésteres de alquilo C1-C20 de ácido acrílico, ésteres de alquilo C1-C20 de ácido metacrílico y monómeros aromáticos de vinilo; - uno o más monómeros monoetilénicamente insaturados M2, que son seleccionados entre ácidos monocarboxílicos monoetilénicamente insaturados que tienen de 3 a 6 átomos de carbono y ácidos dicarboxílicos monoetilénicamente insaturados que tienen de 4 a 6 átomos de carbono, y - opcionalmente uno o más monómeros no iónicos M3, que son diferentes de los monómeros M1; en la que al menos una etapa, la cantidad relativa de monómeros M2 añadidos en esta etapa es de al menos 6% en peso, en base a la cantidad total de monómeros añadidos en dicha etapa, siendo la cantidad total de monómeros M2 de 0,05 a 5% en peso, en base a la cantidad total de la composición de monómeros M; b) un pigmento de dióxido de titanio; c) un dispersante polimérico PD que es seleccionado entre homo y copolímeros de monómeros M4, que son seleccionados entre ácidos monocarboxílicos monoetilénicamente insaturados que tienen de 3 a 6 átomos de carbono y ácidos dicarboxílicos monoetilénicamente insaturados que tienen de 4 a 6 átomos de carbono, en la que los monómeros M4 constituyen al menos el 95% en moles de los monómeros que forman el dispersante polimérico, y en la que el dispersante polimérico PD tiene un peso molecular promedio en número, determinado por medio de GPC, de como máximo 6000 Dalton; y d) un polímero espesante asociativo.
