摘要：
A process for preparing a pigment dispersion, which comprises mixing a first solvent composed of an organic solvent in which a pigment has been dissolved with a second solvent which lowers the solubility of the pigment in the presence of a dispersant, thereby precipitating and dispersing particles of the pigment in a mixed solvent, wherein a pigment derivative to which a hydrophobic substituent having affinity for the first solvent has been bonded is used as the pigment.
