摘要： Fluorescent colorant compositions contain a pigment and a resin. The pigment is a crystalline, azo-based, fluorescent pigment obtained from a coupling reaction of a specific diazo compound, which was obtained from a particular aromatic amine, with a particular acetoacetylamino-containing aromatic coupler. As crystalline characteristics of the crystalline, azo-based, fluorescent pigment, the ratio (h/w) of a height (h) of a maximum peak to its half-value width (w) in a diffraction angle (20) range of from 5 to 35° in an x-ray diffraction spectrum of the pigment may preferably be 20 or greater. Also disclosed are coloring processes and colored articles, which make use of the fluorescent colorant compositions.
