Beschreibung
Zusammenfassung:	A solid dispersion of pigment for an aqueous composition includes a pigment and an ethoxylated alcohol. The solid dispersion of pigment is adapted for being directly incorporated into the aqueous composition with reduced shear for coloration. A method of preparing a solid dispersion of pigment for an aqueous composition with reduced shear mixing includes heating the mixture of an ethoxylated alcohol and a pigment, and cooling the mixture to obtain the solid dispersion of pigment. L'invention porte sur une dispersion solide de pigment pour une composition aqueuse comprenant un pigment et un alcool éthoxylé. La dispersion solide de pigment est conçue pour être directement incorporée dans la composition aqueuse avec un cisaillement réduit pour la coloration. L'invention porte également sur un procédé de préparation d'une dispersion solide de pigment pour une composition aqueuse avec un mélange à cisaillement réduit comprenant le chauffage du mélange d'un alcool éthoxylé et d'un pigment, et le refroidissement du mélange pour obtenir la dispersion solide de pigment.
