A phthalocyanine-based pigment is dissolved in a good solvent to which a pigment dispersant comprising a compound represented by the general formula (I) is added to prepare a pigment solution, and a solvent which is compatible with the good solvent and becomes a poor solvent for the phthalocyanine-based pigment. The manufacturing method of the phthalocyanine pigment microparticles | fine-particles which mix and produce a phthalocyanine pigment as microparticles | fine-particles of a nanosize.n n n n n n n n (Wherein, Q represents an organic dye residue selected from an anthraquinone dye, etc., X represents -CO-, etc., Y 1 represents -NH- or -O-, Z represents a hydroxyl group, etc., R 1 , R 2 each independently represents an alkyl group, m represents an integer of 1 to 6, n represents an integer of 1 to 4) |
