    摘要: An object of the present invention is to provide a method for producing a pigment composition that can achieve both a reduction in the number of coarse particles that may be contained in the pigment composition and improvement in the production efficiency of the pigment composition. The present invention relates to a method for producing a pigment composition in which a pigment is dispersed in a liquid medium by a pigment dispersion resin by undergoing step 1 in which a raw material composition containing the pigment, the pigment dispersion resin, and the liquid medium is processed with a dispersing machine, the dispersing machine being a dispersing machine including a configuration allowing the raw material compositions to collide with each other.
