Document Type and Number:
Japanese Patent JP2013032413
Kind Code:
A
Abstract:
To provide an azo pigment which is high not only in color characteristics such as hue and light resistance but also, especially, in purity, and has a new crystalline form, in which pyrazole rings having specific substituents are linked through azo group and triazine ring, and to provide a dispersed substance of the azo pigment and a tinting composition, and to provide excellent printed matters in which the variation of performance due to the difference among lots is reduced by using the azo pigment as inkjet recording ink.
The azo pigment or a tautomer thereof is represented by formula (1), and has distinct X-ray diffraction peaks at Bragg angles (2θ±0.2°) of 4.9°, 8.8° and 13.1° in CuKα characteristic X-ray diffraction.
