Fillers and / or pigments comprising a composite or an aqueous slurry of a composite of inorganic and / or organic microparticles and nano-dolomite particles

摘要

Fillers and / or pigments comprising a composite or an aqueous slurry of a composite, wherein the composite comprises inorganic and / or organic pigment and / or filler particles, which are at least partially coated with a composition comprising dolomite particles, and a binder, characterized in that - The spherical equivalent diameter of the pigment and / or filler particles of the composite in the micrometer range of greater than 0.2 microns and the spherical equivalent diameter of the dolomite particles in the nanometer range of ≤ 200 nm; and - The binder is a copolymer comprising as monomers one or more dicarboxylic acids and one or more monomers from the group of diamines, triamines, dialkanolamines or trialkanolamines.
