ABSTRACT:
The present invention provides a method of producing a pigment dispersion, comprising the steps of: preparing a solution in which two or more color pigments and a dispersant are dissolved in a solvent containing an aprotic organic solvent in the presence of an alkali; preparing a medium that decreases a solubility of the two or more color pigments by being added to the solution; feeding the solution and the medium to respective microchannels; and depositing the two or more color pigments by merging the solution and the medium transported through the respective microchannels.
