摘要

PROBLEM TO BE SOLVED: To provide a pigment dispersion having desired pigment concentration and obtained by condensing a highly and uniformly dispersed pigment fine particle dispersion.

SOLUTION: This method for producing the nano-pigment dispersion is characterized by mixing a solution of a pigment in a good solvent with a solvent which is compatible with the good solvent and is poor for the pigment, thereby producing nano-size pigment fine particles to prepare the nano-pigment particle dispersion which has pigment concentration of 0 to 10 mass% on the production of the particles, and then concentrating the dispersion in higher final pigment concentration of ≥5 mass% than a pigment concentration on the production of the pigment.
