There is provided a pigment dispersion including water, an aqueous polymer and a pigment as essential components, wherein the aqueous polymer is a carboxyl group-containing polyurethane which is formed by reacting a diol compound, a diisocyanate compound and a reaction product, which is mainly composed of a compound represented by general formula (1) and prepared by reacting a diol compound having one or two carboxyl groups within each molecule with a diisocyanate compound and which also has a reaction index as calculated by (Formula 1) within a range from 0.95 to 1.10. (see formula 1) Reaction index = (reaction rate of isocyanate group) x [(number of moles of diisocyanate compound (B))/ (number of moles of diol compound (A))]
L'invention porte sur une dispersion de pigment contenant de l'eau, un polymère aqueux et un pigment comme constituants essentiels, le polymère aqueux étant un polyuréthane contenant des groupes carboxy qui est obtenu par réaction d'un composé diol, d'un composé diisocyanate et d'un produit de réaction, lequel est principalement composé d'un composé représenté par la formule générale (1) et obtenu par réaction d'un composé diol ayant un ou deux groupes carboxy dans chaque molécule et d'un composé diisocyanate et a un indice de réaction tel que calculé par (formule 1) de 0,95-1,10. L'invention porte également sur une encre aqueuse pour l'impression par jet d'encre. Indice de réaction = (vitesse de réaction d'un groupe isocyanate) x (nombre de moles de composé diisocyanate (B)/nombre de moles de composé diol (A)) (formule 1).
