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 pcnt 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 pcnt 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 pcnt of the monomers forming the polymeric dispersant; and d) an associative thickener polymer.
