摘要:
A C.I. Pigment Yellow 74 as an insoluble azo pigment is provided. This C.I. Pigment Yellow 74 is crystalline particles. The ratio (26.6°/11.7°) of a diffraction intensity of a peak at 26.6° to a diffraction intensity of a peak at 11.7° in terms of Bragg angle (2¸±0.2°) as measured by powder X-ray diffraction using CuK ±-radiation is 0.85 to 1.12, and the average primary particle size is 20 to 130 nm. The use of this C.I. Pigment Yellow 74 as a colorant in a coloring composition enables to provide the coloring composition with excellent dispersibility and good particle size stability and storage stability compared with conventional pigments. The use of this coloring composition enables the formation (recording) of images having excellent clarity and transparency of such high levels that have not been achievable by conventional technologies.
