Zusammenfassung:PROBLEM TO BE SOLVED: To provide a fluoflavine pigment excellent in chromatic properties such as coloring power and clearness, durability such as light resistance, weatherability, and in particular heat resistance, and to provide a pigment dispersion having excellent chromatic properties using the same. SOLUTION: This fluoroflavine pigment is characterized by being shown by the general formula (1) [wherein, R1 to R4 are each H, a halogen atom, OH, a carboxylic acid group or (halogen-substituted) 1-3C alky, (halogen- substituted) 1-3C alkoxy or (halogen-substituted) phenyl] and having a specific surface area of 10-50 m /g.
