Description

  

      Zusatzpatent    zum Hauptpatent     Nr.89057.       Verfahren zur Darstellung eines     o-Ogyazofarbstoffes.       Es     wurde    gefunden, dass durch Kuppeln  von 3     #    4     #    5     #        6-Tetrachlor-2-diazo-l-oxybenzol     mit     1-Oxy        naphtalin-5-sulfosäure    ein Farbstoff  erhalten wird, der auf Wolle mit Chrombeizen  ein violettes Blau von guter Wall-, Wasch-,  Reib- und Lichtechtheit liefert.

      <I>Beispiel:</I>    Die aus 24,8 Teilen 3     #    4     #    5     #        6-Tetrachlor-          2-amino-1-oxybenzolbereitete        Diazoverbindung     vereinigt man mit 25 Teilen     1-Oxyiiaphtalin-          5-sulfosai.,irem    Natrium in     sodaalkalischer     Lösung. Der     Farbstoff    wird in der üblichen  Weise aufgearbeitet.



      Additional patent to main patent number 89057. Process for the preparation of an o-ogyazo dye. It has been found that by coupling 3 # 4 # 5 # 6-tetrachloro-2-diazo-1-oxybenzene with 1-oxynaphthalene-5-sulfonic acid, a dye is obtained which on wool with chrome stains has a violet blue of good wall -, washing, rubbing and lightfastness.

      <I> Example: </I> The diazo compound prepared from 24.8 parts of 3 # 4 # 5 # 6-tetrachloro-2-amino-1-oxybenzene is combined with 25 parts of 1-oxyiiaphthalene-5-sulfosai., Irem sodium in soda-alkaline solution. The dye is worked up in the usual way.
