Description

  

  Verfahren zur Herstellung eines     o-Ogyazofarbstoffes.       Es wurde gefunden, dass durch Kuppeln  von 3     #    4     #        6-Trichlor-2-amino-l-oxybenzol    mit       1-Benzoylamino    - 8 -     oxynaphtalin-4-        sulfösäure     ein     Farbstoff    erhalten wird, der aus saurem  Bade stumpf violette Nuancen liefert und  dessen Chromlack klar blau ist.  



  <I>Beispiel:</I>  Die aus 21,3 Teilen 3     #    4     #        6-Trichlor-          2-amino-l-oxybenzolbereitete        Diazoverbindung     vereinigt man mit 34,5 Teilen     1-Benzoyl-          amino-8-oxynaphtalin-4-sulfosäure    in     soda-          alkalischer    Lösung. Der     Farbstoff    wird in  üblicher Weise aufgearbeitet.



  Process for the preparation of an o-ogyazo dye. It has been found that by coupling 3 # 4 # 6-trichloro-2-amino-1-oxybenzene with 1-benzoylamino-8-oxynaphthalene-4-sulfoic acid, a dye is obtained which, from acidic bath, gives dull purple nuances and its Chrome paint is clear blue.



  <I> Example: </I> The diazo compound prepared from 21.3 parts of 3 # 4 # 6-trichloro-2-amino-1-oxybenzene is combined with 34.5 parts of 1-benzoylamino-8-oxynaphthalene-4- sulfonic acid in a soda-alkaline solution. The dye is worked up in the usual way.
