Abstract

L'invention décrit l'obtention de compositions de pigments colorés ayant une meilleure dispersabilité. On obtient ces pigments colorés pulvérulents en mélangeant intimement une suspension du pigment, sans agent de dispersion, avec un latex aqueux de polymère, en coagulant le polymère par addition d'un électrolyte sous une action intense de mélange puis en séparant éventuellement le pigment de façon connue, en le séchant et éventuellement en le broyant. Les compositions obtenues peuvent servir à pigmenter des matières plastiques, des encres d'impression, des laques des peintures et produits pour l'enduction.The invention describes the production of colored pigment compositions having better dispersability. These powdery colored pigments are obtained by intimately mixing a suspension of the pigment, without dispersing agent, with an aqueous polymer latex, by coagulating the polymer by adding an electrolyte under an intense mixing action and then optionally separating the pigment in such a way. known, by drying it and possibly by grinding it. The compositions obtained can be used for pigmenting plastics, printing inks, lacquers, paints and products for coating.
