<p><P>PROBLEM TO BE SOLVED: To provide a method for easily producing a pigment dispersion having small particle diameter, uniform particle size distribution and high color development, and enabling easy saving of installation space and smooth transfer to mass-production scale. <P>SOLUTION: The method for producing a pigment dispersion contains a step to prepare a solution containing pigments of two or more colors and a dispersing agent in a solvent containing an aprotic organic solvent in the presence of an alkali, a step to prepare a precipitation medium for the pigments having two or more colors, a step to supply the solution and the precipitation medium to separate micro-flow channels, and a step to precipitate the pigments of two or more colors by joining the streams of the solution and the precipitation medium discharged from the separate micro-flow channels. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
