  Verfahren zur Darstellung orangefarbener Disazofarbstoffe für Wolle. 



   In der   Stamm-Patentschrift   wurde ein Vorfahren zur Darstellung von walkechten Disazofarbstoffen beschrieben, welches darin besteht, dass man die Tetrazoverbindnngen der Benzidin- oder Tolidin-m-disulfosäure mit 2 Molekülen Methylketol   (&alpha;-Methylindol)   oder in beliebiger Reihenfolge mit 1 Molekül Methylketol   (&alpha;-Methylindol)   und 1   Molokü)   I-Phenyl-3-methyl-5-pyrazolon kuppelt. 



   Es wurde nun gefunden, dass, wenn man die genannten Tetrazoverbindungcn der Benzidin- bezw. Tolidinsulfosäuren der Formeln : 
 EMI1.1 
 
 EMI1.2 
 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the preparation of orange disazo dyes for wool.



   In the parent patent, an ancestor for the preparation of mill-fast disazo dyes was described, which consists in that the tetrazo compounds of benzidine or tolidine-m-disulfonic acid with 2 molecules of methyl ketol (α-methylindole) or in any order with 1 molecule of methyl ketol (α-methylindole) and 1 Molokü) I-phenyl-3-methyl-5-pyrazolone couples.



   It has now been found that if the tetrazo compounds mentioned are the benzidine or. Tolidinsulfonic acids of the formulas:
 EMI1.1
 
 EMI1.2
