AZO PIGMENT COMPOSITION, PROCESS FOR PRODUCTION OF THE COMPOSITION, DISPERSIONS CONTAINING THE COMPOSITION, COLORED COMPOSITIONS AND JET PRINTING INK

摘要

To provide an azo pigment composition having extremely good hue and extremely good light fastness and showing excellent tinctorial strength (color density) and, preferably, to provide an azo pigment composition further containing an azo pigment having characteristic X-ray diffraction peaks at different positions or a tautomer thereof. An azo pigment composition which contains at least one azo pigment represented by the following formula (1) and having characteristic peaks at Bragg angles (2¸±0.2°) of 7.2° and 25.9° in X-ray diffraction with the characteristic Cu K± line, or a tautomer thereof:
