Description

  

  Verfuhren zur Darstellung eines     Beizenfarbstoffs.       Es wurde gefunden, dass durch Kupplung       voii_2-Diazo-l-oxybenzol-4-sulfösäure    mit     8-          oxychinolin    ein Farbstoff erhalten wird, der  Wolle in brauner     Nuance    anfärbt, die durch       Nachchromieren    in sehr licht- und     walkechtes     Bordeaux übergeht.  



  <I>Beispiel,</I>       11I    an dianotiert 18,9 Teile     2-Amino-l-oxy-          benzol-4-sulfosäüre    in der üblichen Weise und  lässt die     Diazoverbindung    in eine     ätzalkalische          Lösung    von 14,5 Teilen     8-Oxychinolin    laufen.  Nach beendeter Kupplung salzt man den       Farbstoff    aus und arbeitet ihn wie gewöhn-    lieh auf. Er färbt Wolle braun; durch Nach  chromieren erhält man ein sehr licht- und       walkechtes    Bordeaux.



  Procedure for the preparation of a stain dye. It has been found that by coupling voii_2-diazo-1-oxybenzene-4-sulfoic acid with 8-oxyquinoline, a dye is obtained which dyes wool in a brown shade, which changes to very lightfast and millfast bordeaux after chroming.



  <I> Example, </I> 11I an dianotized 18.9 parts of 2-amino-1-oxy-benzene-4-sulfonic acid in the usual way and lets the diazo compound run into a caustic solution of 14.5 parts of 8-oxyquinoline . After the coupling is complete, the dye is salted out and worked up as usual. He dyes wool brown; after chrome-plating, you get a very lightfast and whackfast Bordeaux.
