摘要：
There is provided an azo pigment having excellently good color reproducibility, dispersibility, and storage stability of pigment dispersions and having excellent hue and tinctorial strength. An azo pigment represented by the following formula (1) and having characteristic peaks at Bragg angles (28:f::0.2°) of 7.2,p, 13.4°, 15.0°, and 25.9 in X-ray diffraction with characteristic Cu K± line, and a tautomer thereof:
