摘要： Disclosed is a pigment dispersion that can be used for an ink jet printing-use pigment ink that affords stable printing characteristics and has excellent storage stability in an ink jet printer having a head driven at a high frequency and having finer nozzles in order to enhance image quality and raise the speed. Disclosed is also a method for manufacturing this pigment dispersion. This manufacturing method includes a step of surface-treating a self-dispersing type of pigment, in which at least hydrophilic, dispersibility-imparting group is introduced to the pigment surface directly and/or via a polyvalent group, and a step of dispersing the self-dispersing pigment obtained in said surface-treating step in an aqueous medium, wherein the dispersion step is a step in which at least the self-dispersing pigment, a wetting agent, and water are dispersed in the form of a liquid mixture.
