<p>An azo pigment selected from the group consisting of: an azo pigment represented by the following formula (1), which has: a characteristic X-ray diffraction peak at Bragg angles (2¸±0.2°) of 6.9°, 21,5°, and 27.3° in CuK± characteristic X-ray diffraction, a peak height at 11.9° of 0.6 or less relative to a peak height at 10.9° or a tautomer thereof, or a salt, hydrate, or solvate of the azo pigment or tautomer thereof; and an azo pigment represented by the following formula (1), which has: a characteristic X-ray diffraction peak at Bragg angles (2¸±0.2°) of 6.9°, 25.8°, and 27.1° in CuK± characteristic X-ray diffraction, a peak height at 10.9° of 0.2 or less relative to a peak height at 11.9° or a tautomer thereof, or a salt, hydrate, or solvate of the azo pigment or tautomer thereof.</p> |
