Disclosed is a coloring compound that has low solubility in water, high solubility in an organic solvent, and improves dispersibility of an azo pigment in an organic solvent. A dye compound represented by the following general formula (1): Since the dye compound represented by the general formula (1) has a high affinity for an azo pigment, use as a pigment dispersant improves the dispersibility of the azo pigment and provides a pigment composition having a good color tone. I can do it. Further, by using the pigment composition, a pigment dispersion excellent in dispersibility in an organic solvent and having a good color tone, particularly a pigment dispersion of a styrene monomer.
