Abstract:
A process for preparing an aqueous pigment dispersion is provided in which a pigment, a coating agent, a grinding agent and a vehicle are subjected to grinding, followed by removal of the grinding agent and the vehicle to form a press cake, and dispersing the press cake to form a pigment dispersion. Also disclosed is an ink-jet ink containing an aqueous vehicle and the aqueous pigment dispersion thus made.
