 kannter Weise abgeschieden. Er erweist sich in jeder Beziehung identisch mit dem gemäss Beispiel 1 der französischen Patentschrift Nr. 351125 erhältlichen Farbstoff. 



   In analoger Weise erfolgt die Darstellung der Farbstoffe unter Verwendung anderer   o-Diazonaphtolsulfosäuren,   wie z. B. 1 : 2   Diazonaphtol-6-sulfosäure,   2 : 1 Diazonaphtol- 4-sulfosäure, 2 :   1-Diazonaphtol-5-sulfosäure   usw. 



   Ebenso lassen sich an Stelle der in den Beispielen genannten Komponenten auch andere Azokomponenten verwenden, ohne dass das Verfahren eine wesentliche Änderung erfahren müsste. Ferner können die Mengenverhältnisse der zugesetzten organischen Verbindungen innerhalb weiter Grenzen variiert werden.

 deposited in a familiar way. It turns out to be identical in every respect to the dye obtainable according to Example 1 of French Patent No. 351125.



   The dyes are represented in an analogous manner using other o-diazonaphthol sulfonic acids, such as. B. 1: 2 diazonaphthol-6-sulfonic acid, 2: 1 diazonaphthol-4-sulfonic acid, 2: 1-diazonaphthol-5-sulfonic acid, etc.



   Likewise, other azo components can also be used instead of the components mentioned in the examples, without the process having to undergo any significant change. Furthermore, the proportions of the added organic compounds can be varied within wide limits.
