<P>PROBLEM TO BE SOLVED: To provide a method of producing a low-viscosity dispersion containing organic pigment fine particles having a small particle size and a narrow particle size distribution, a method of producing an organic pigment fine particle dispersion, in which the amount of a dispersant dispersing organic pigment fine particles can be reduced, even a dispersant labile to a high-concentration alkali can be made usable, and a variety of dispersants are applicable, and an inkjet recording ink and a paint using the organic pigment fine particles obtained by the same. <P>SOLUTION: The method of producing an organic pigment fine particle dispersion includes feeding at least three liquids, which are a solution containing an organic pigment dissolved in an organic solvent in the presence of an alkali, a solution containing a dispersant, and an aqueous medium, into separate channels L1-L4 and bringing the at least three liquids into junction with each other in a channel simultaneously to produce fine particles of the organic pigment. <P>COPYRIGHT: (C)2010,JPO&INPIT |
