PROBLEM TO BE SOLVED: To provide a method for producing a color material substance dispersion capable of obtaining a color material substance dispersion having a small particle size containing a color material and a block copolymer using a microreactor. SOLUTION: A color material and a block copolymer are mixed in the flow path of a microreactor 1 having flow paths 2 and 3, and a color material substance including the color material and the block copolymer is dispersed. A method for producing a color material substance dispersion to obtain a product. The synthesis, precipitation or crystallization of the color material is carried out in a microreactor channel equipped with a channel. Mixing is performed by introducing a fluid containing a color material and a fluid containing a block copolymer from different channels into the mixing channel and bringing these fluids into contact with each other in the mixing channel.
