Provided is a process for the preparation of a pigment dispersion which comprises a pigment surface treatment step of introducing at least one hydrophilic dispersibility-providing group onto the surface of a pigment directly and/or with the interposition of a polyvalent group, and a dispersion step of dispersing a surface-treated pigment obtained at the surface treatment step in an aqueous medium, characterized in that the dispersion step involves the dispersion of the surface-treated pigment in admixture with a wetting agent and water and a resin for providing dispersibility and/or fixability is added during and/or after the dispersion step.
