摘要:
The present invention relates to latex paints containing a) a multistage carboxylated polymer latex binder obtainable by multistage aqueous emulsion polymerisation of at least one non-ionic monomer 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 where in at least one stage, monomers M2 added in this stage is at least 6% by weight; b) a titanium dioxide pigment; c) a polymeric dispersant 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 make up at least 85% of the monomers forming the polymeric dispersant; and d) a thickener polymer.
