Description

  

  Verfahren zur Darstellung eines     o-Ogyazofarbstoffes.       Es wurde gefunden, dass durch Kuppeln von  3     #    4     #        5-Tiichlor-2-diazophenol    mit     1-Aeetyl-          amiiio-8-naphtol-4-sulfosäure    ein Farbstoff er  halten wird, der auf Wolle mit Hilfe von  Chrombeizen blaue Nuancen von guter Wasch-,       Walk-    und Lichtechtheit liefert.

      <I>Beispiel:</I>  Die aus 21,3 Teilen 3     #    4     #        5-Trichlor-          2-amino-l-oxybenzol    erhaltene     Diazoverbin-          dung    wird mit 28,1 Teilen     1-Acetylaniino-          8        oxynaphtalin-4-sulfosäure    in     sodaalkalischer     Lösung vereinigt. Der Farbstoff wird in der  üblichen Weise aufgearbeitet.



  Process for the preparation of an o-ogyazo dye. It has been found that by coupling 3 # 4 # 5-Tiichlor-2-diazophenol with 1-Aeetyl- amiiio-8-naphthol-4-sulfonic acid he will keep a dye, which on wool with the help of chrome stains blue shades of good Provides washing, milling and lightfastness.

      <I> Example: </I> The diazo compound obtained from 21.3 parts of 3 # 4 # 5-trichloro-2-amino-1-oxybenzene is mixed with 28.1 parts of 1-acetylaniino-8-oxynaphthalene-4-sulfonic acid combined in soda-alkaline solution. The dye is worked up in the usual way.
