Description

  

  Verfahren zur Darstellung eines     o-Oxyazof %rbstoffes.       Es wurde gefunden,     dass    durch Kuppeln  von<B>3 -</B> 4<B>-</B>     5-Trichlor-2-diazo-l-oxybenzol    mit       1-Arniiio-8-naphtol-2   <B>-</B>     4-disulfosäure    ein Farb  stoff erhalten wird, der Wolle aus saurem  Bade     korinth    färbt- beim     Nachehroinieren     entsteht ein Grünblau.  



  <I>Beispiel:</I>  Die aus<B>21,3</B> Teilen<B>3 -</B> 4<B>-</B>     5-Trichlor-2-          amiiio-l-oxybenzol    bereitete     Diazoverbindung     kuppelt man mit<B>3,5</B> Teilen     1-Amii)o-8-oxy-          naphtalin-2   <B>-</B>     4-disulfosäure        (Mononatriumsalz)     in     sodaalkalischer    Lösung. Der Farbstoff wird  in der üblichen Weise aufgearbeitet,



  Process for the preparation of an o-oxyazo dye. It was found that by coupling <B> 3 - </B> 4 <B> - </B> 5-trichloro-2-diazo-1-oxybenzene with 1-arniiio-8-naphtol-2 - </B> 4-disulphonic acid a dye is obtained that dyes wool from acidic bath corinth - a green-blue arises when it is processed afterwards.



  <I> Example: </I> The <B> 21,3 </B> parts <B> 3 - </B> 4 <B> - </B> 5-Trichlor-2- amiiio-l- Diazo compound prepared oxybenzene is coupled with 3.5 parts of 1-amii) o-8-oxynaphthalene-2 - 4-disulfonic acid (monosodium salt) in a soda-alkaline solution. The dye is worked up in the usual way,
