Description

  

  Verfahren zur Darstellung eines Beizenfarbstoffs.    <B>Es</B> wurde gefunden,     dass    durch Kupplung  von 6-Nitro-2-diazo-l-oxybetizo-4-stilfosäure  mit 8-Oxychinolin ein Farbstoff erhalten wird,  der Wolle in brauner Nuance anfärbt, die  durch Nachchromieren in seht, licht- 'und  walkechtes Bordeaux übergeht.  



  Beispiel:  A Han diazotiert 23,4 Teile     6-Nitro-2-ainitio-          1-oxybeiizol-4-sulfosäure    in der übliehen Weise  und lässt die Diazoverbindung in eine alkalische  Lösung von 1455 Teilen 8-Oxychinoliii laufen.  Nach beendeter Kupplung wird der Farbstoff  wie üblich aufgearbeitet. Er färbt Wolle  direkt braun; durch Nachchromieren geht die    Färbung in ein sehr licht- und walkechtes  Bordeaux Über.



  Process for the preparation of a mordant dye. It has been found that the coupling of 6-nitro-2-diazo-1-oxybetizo-4-stilfonic acid with 8-oxyquinoline gives a dye which dyes wool in a brown shade, which is then chromated in see, light- and whale-fast Bordeaux passes over.



  Example: A Han diazotizes 23.4 parts of 6-nitro-2-ainitio-1-oxybeiizole-4-sulfonic acid in the usual manner and lets the diazo compound run into an alkaline solution of 1455 parts of 8-oxyquinoline. After the coupling has ended, the dye is worked up as usual. He dyes wool brown directly; after chrome plating, the color changes into a very lightfast and whalefast Bordeaux.
