A pigment dispersion comprising pigment, an aqueous carrier selected from water and a mixture of water and at least one organic solvent, and a pigment dispersant is described. The pigment dispersant is prepared by polymerizing (i) at least one prepolymer having a radically polymerizable group, and (ii) at least one second monomer. The prepolymer is prepared by controlled radical polymerization, e.g., atom transfer radical polymerization, of at least one radically polymerizable first monomer. The second monomer forms a polymeric backbone segment of the pigment dispersant, and the prepolymer forms polymeric segments that are pendent to the backbone. The backbone segment of the pigment dispersant in hydrophobic, while at least a portion of each pendent polymeric segment is hydrophilic.

L'invention concerne une dispersion contenant un pigment, un support aqueux sélectionné dans le groupe constitué par de l'eau et un mélange d'eau et d'au moins un solvant organique, et un dispersant. Le dispersant est préparé par polymérisation: i) d'au moins un prépolymère qui présente un groupe se prêtant à une polymérisation radicalaire; et ii) au moins un second monomère. Le prépolymère est préparé par polymérisation radicalaire contrôlée (par exemple, une polymérisation radicalaire, par transfert d'atomes, d'au moins un premier monomère se prêtant à une polymérisation radicalaire). Le second monomère forme un segment squelette polymérique du dispersant, et le prépolymère forme des segments polymériques pendants du squelette. Le segment squelette du dispersant à base de pigment est hydrophobe tandis qu'au moins une partie de chaque segment polymérique pendant du squelette est hydrophile.
