  Verfahren zur Darstellung eines     Beizenfar        bstoffs.       Es wurde gefunden, dass durch Kupplung  von     4-Nitro-2-diazo-l-oxybenzol-6-sulfosäure     mit     8-Oxychinolin    ein Farbstoff erhalten wird,  der Wolle in brauner Nuance anfärbt, die  durch     Nachchromieren    in sehr licht- und       walkechtes    Bordeaux übergeht.  



       Beispiel:          plan        diazotiert        23;4    Teile     4-Nitro-2-ainino-          1-oxybenzol-6-sulfösäure    in der üblichen Weise  und lässt     dieDiazoverbindung    in eine alkalische  Lösung von 14,5 Teilen     8-Oxychinolin    -ein  laufen. Nach beendeter Kupplung wird der       Farbstoff    wie üblich. aufgearbeitet; er färbt  Wolle direkt     braun;    durch     Nächehromieren       geht die Färbung in ein sehr -licht- und wallr  echtes Bordeaux über:



  Process for the preparation of a stain dye. It has been found that by coupling 4-nitro-2-diazo-1-oxybenzene-6-sulfonic acid with 8-oxyquinoline, a dye is obtained which dyes wool in a brown shade, which changes into very lightfast and milled Bordeaux after chrome-plating .



       Example: plane diazotized 23; 4 parts of 4-nitro-2-ainino-1-oxybenzene-6-sulfoic acid in the usual way and lets the diazo compound run into an alkaline solution of 14.5 parts of 8-oxyquinoline.
