摘要

Bragg angle as measured by powder X-ray diffraction using a CuKα ray in the (2θ ± 0.2 °), the diffraction intensity of the peak of 26.6 ° to the diffraction intensity of the peak of 11.7 ° the ratio (26.6 ° / 11.7 °) is 0.85 to 1.12, and an average primary particle diameter of the insoluble azo pigment is characterized in that the crystal grains of 20~130nm C. I. By providing a pigment yellow 74, as compared with conventional pigments, is excellent in dispersibility when it is utilized in the coloring agent of the coloring composition, the particle size stability and storage stability can provide good coloring composition it is possible to, by using a colored composition, higher levels of which were not achieved in the prior art, enabling image formation excellent in vividness and transparency (recording).
