ABSTRACT:
A method of producing a dispersion of a pigment, comprising: bringing a solution in which an organic pigment is dissolved, and an aqueous medium, into contact with each other in a channel having an equivalent diameter of 1 mm or less, thereby making the pigment into a fine particle thereof, wherein at least one of the solution and the aqueous medium comprises at least one anionic dispersing agent.
