Abstract:
An object of the invention is to provide an azo pigment having extremely good dispersibility and dispersion stability and having excellent hue and tinctorial strength and, preferably, having a long axis observed with a transmission microscope of from 0.01 μm to 30 μm. An azo pigment which is represented by the following formula (1) and having characteristic peaks at Bragg angles (2θ±0.2°) of (i) 7.6° and 25.6°, (ii) 7.0°, 26.4°, and 27.3°, or (iii) 6.4°, 26.4°, and 27.2° in X-ray diffraction with characteristic Cu Kα line, or a tautomer thereof:
