A method of making polymer-coated pigment particles, involving the steps of providing a plurality of pigment particles, each of which has an outer surface coated with a layer of material that operates as a nucleus for initiating polymerization on the outer surface of each of the pigment particles. The pigment particles are mixed with a reaction mixture containing a solvent and a monomer material, wherein the layer of material coating each of the pigment particles causes the monomer material to polymerize on the outer surface of substantially each of the pigment particles to form a polymer coating thereon.
L'invention concerne un procédé de fabrication de particules pigmentaires enduites de polymères qui consiste à prendre plusieurs particules pigmentaires, chacune d'entre elles ayant une surface extérieure enduite d'un couche de matière agissant comme un noyau permettant d'amorcer la polymérisation sur la surface extérieure de chaque particule pigmentaire. Les particules pigmentaires sont mélangées à un mélange de réaction contenant un solvant et une matière monomère, dans lequel la couche de matière enduisant chaque particule pigmentaire entraîne la polymérisation de la matière monomère sur la surface extérieure de sensiblement chaque particule pigmentaire afin d'y former un enduit polymère.
