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： A pigment is disclosed wherein the pigment includes a platy substrate or uniform platy substrate coated with an odd number of layers of alternating layers of high or low refractive index material, wherein each layer has a refractive index that differs from adjacent layers by at least 0.2; and the pigment has from about 40 to about 100% reflectance of light having a wavelength of 280 nm to 400 nm. Processes for making and using the pigments are also disclosed. These pigments can find application in paints, plastics, cosmetics, glass, printing inks, and glazes.
