摘要：
The invention relates to a novel crystallographic modification (".beta.-modification") being stable under dyeing conditions of the dyestuff of the formula ##STR1## which is characterized by an X-ray diffraction pattern as shown in FIG. 1 with characteristic reflexes at the following glance angles .theta. (CuK.sub..alpha. radiation) with the relative intensities:______________________________________ .phi. 3.71 6.62 7.85 8.6 9.43 10.51 11.8 12.57 relat. 67 44 34 36 60 60 46 100 intensity ______________________________________ to processes for their manufacture and to their use for dyeing fibrous materials of cellulose esters or of synthetic linear polyesters or blended fabrics of these polyesters and wool or rayon.
