Abstract: The modification (I) of the dyestuff of formula: has an x-ray diffraction diagram showing lines of strong intensity at 9.1 and 25.5 degrees, of medium intensity at 16.1, 17.1, 17.9, 20.1, 20.8, and 27.1 degrees and of weak intensity at 4.8, 11.2, 14.4 and 23.7 degrees at a diffraction angle of 2 H. (I) is dispersion-stable, unlike the alpha-modification (II), and does not flocculate out of aq. medium after prolonged exposure to high temp. It is prepd. by heating (II), opt. in water and/or water-sol. org. solvent.
