Description

  

  Verfahren zur Darstellung eines     o-Ogyazofarbstoffes.       Es wurde gefunden, dass durch Kuppeln  von 3     #    4     #        6-Trichlor-2-diazo-l-oxybenzol    mit       1-Amino-8-naphtol-2        #        4-disulfosäure    .ein Farb  stoff erhalten wird, der auf chromgebeizter  Wolle grünblaue, gleichmässige walk-,     licht-          und    reibechte Nuancen liefert.  



  <I>Beispiel:</I>  <B>21,3</B> Teile 3     #    4     #        6-Trichlor-2-amino-l-oxy-          benzol    werden in der üblichen Weise     diazo-          tiert    und mit einer Lösung von<B>35</B> Teilen  1-     Amino    - 8 -     oxynaphtalin    - 2     #    4 -     disulfosäure          (Mononatriumsalz)    in     sodaalkalischer    Lösung    vereinigt. Der Farbstoff wird auf die übliche  Weise aufgearbeitet.



  Process for the preparation of an o-ogyazo dye. It has been found that by coupling 3 # 4 # 6-trichloro-2-diazo-1-oxybenzene with 1-amino-8-naphthol-2 # 4-disulfonic acid, a dye is obtained that turns green-blue on chrome-stained wool provides evenly milled, lightfast and rubfast nuances.



  <I> Example: </I> <B> 21.3 </B> parts 3 # 4 # 6-trichloro-2-amino-1-oxybenzene are diazotized in the usual way and with a solution of <B> 35 </B> parts 1 - amino - 8 - oxynaphthalene - 2 # 4 - disulfonic acid (monosodium salt) combined in an alkaline soda solution. The dye is worked up in the usual way.
