ABSTRACT:
It is possible by heating at temperatures of between 65.degree. and 200.degree. C. to convert the known .alpha.-modification of the azo dye of the formula ##STR1## which is unstable to dyeing, completely into the .beta.-modification which is stable to dyeing. The modification transformation can be performed either with the solid dye or with a suspension thereof in an organic, preferably aromatic, solvent.
The novel dye modification is stable in dispersion under dyeing conditions, and shows no tendency to flocculate.
