Abstract
(EN)
Provided are: a pigment dispersion which, through use thereof in an ink, can adequately increase the color density of a formed image part; an inkjet ink composition and an ink set obtained using the dispersion; and an image formed using the inkjet ink composition, and an image formation method. This pigment dispersion contains an aqueous medium, a pigment, and a pigment dispersant comprising a polymer having an anionic group, the pKa (DMSO) of the polymer before neutralization of the pigment dispersant being 14 or greater. The inkjet ink composition and the ink set use the pigment dispersion. The image is formed and the image formation method forms an image using the inkjet ink composition.

L'invention concerne : une dispersion de pigment qui, par son utilisation dans une encre, peut augmenter de manière adéquate la densité de couleur d'une partie d'image formée ; une composition d'encre pour jet d'encre et un jeu d'encres obtenu à l'aide de la dispersion ; et une image formée à l'aide de la composition d'encre pour jet d'encre, et un procédé de formation d'image. Cette dispersion de pigment contient un milieu aqueux, un pigment et un dispersant de pigment comprenant un polymère ayant un groupe anionique, la pKa (DMSO) du polymère avant la neutralisation du dispersant de pigment étant de 14 ou plus. La composition d'encre pour jet d'encre et le jeu d'encres utilisent la dispersion de pigment. L'image est formée et le procédé de formation d'image forme une image à l'aide de la composition d'encre pour jet d'encre.
