A crystalline form of the dye represented by the following formula (1):
characterized by an X-ray diffraction pattern having a strong peak at the angle of diffraction (2ϑ) of 23.2° and relatively strong peaks respectively at the angles of diffraction (2ϑ) of 8.3°, 12.3°, 20.8°, 21.9°, 25.0°, 27.1°, 29.2° and 30.8° according to X-ray powder diffractometry through the use of a Cu-Kα line and a process for preparing the same by heat-treating a heat-instable crystalline form of the dye represented by the formula (1) in water, water containing a water-soluble organic solvent, or water containing an anionic or nonionic surfactant at a temperature of 40°C or above.
It withstands dyeing at high temperature, e.g. 130°C or higher, to provide dyed fibers having excellent fastness properties.
