The present invention relates to composites, comprising inorganic and/or organic pigments and/or fillers in the form of rnicroparticles, the surface of which is coated at least partially with finely divided nano-dolomiie with the help of binders hased on copolymers comprising as monomers one or more diearboxyjic acids and one or more monomers from the group of diamines, triammcs, dialkanolamines or maikanohitnmes, a method for producing such composites, aqueous slurries thereof, their use, and the use of the inventive binders for coating the microp articles with nano-dolomite.
La présente invention concerne des composites, comprenant des pigments et/ou des matières de remplissage inorganiques et/ou organiques sous forme de microparticules, dont la surface est enduite au moins en partie de dolomite nanométrique finement divisée à l'aide de liants à base de copolymères comprenant en tant que monomères un ou plusieurs acides dicarboxyliques et un ou plusieurs monomères du groupe des diamines, triamines, dialcanolamines ou trialcanolamines, un procédé de fabrication de tels composites, des pâtes aqueuses de ces composites et leur utilisation, ainsi que l'utilisation des liants selon l'invention pour le revêtement des microparticules avec de la dolomite nanométrique.
