    摘要： 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.

    摘要： The present invention relates to polyalkylene imine based polymers, which have aliphatic polyester groups attached to the polyalkylenimine backbone via an carboxamide group. The novel polymers are particularly useful as dispersants for pigments, in particular as dispersants for pigments in non-aqueous compositions. The polyalkylene imine based polymers are characterized by having a) a polyalkylene imine backbone; b) at least one aromatic moiety P.1, which is bound to a nitrogen atom of the polyalkylene imine backbone via an carboxamide or carboximide group; and c) at least one aliphatic polyester moiety P.2, which is bound to a nitrogen atom of the polyalkylene imine backbone via an carboxamide group.
