Description

  

  Verfahren zur Darstellung eines.     o-Oxyazofarbstoffes.       Es wurde gefunden,     dass    durch Kuppeln  von<B>3 -</B> 4<B>-</B>     6-Trichlor-2-diazo-l-oxybenzol    mit       1-Toluolsulfamido-8-naphtol-4-sulfosätire    ein  Farbstoff erhalten wird, der mit Hilfe von  Chrombeizen auf Wolle gleichmässige     walk-,     licht- und reibechte     blaueNuancen    liefert.

    <I>Beispiel:</I>  Die aus<B>21,3</B> Teilen<B>3 -</B> 4<B>-</B>     6-Trichlor-9,-          amino-l-oxybenzol    bereitete     Diazoverbindung          lässt    man in eine     S'Odaalkalische    Lösung von  <B>39,3</B> Teilen     1-Toluolsuliamitio-8-naphtol-4-          sulfosäure    einlaufen. Der Farbstoff wird in  der üblichen Weise aufgearbeitet.



  Method for representing a. o-oxyazo dye. It has been found that by coupling <B> 3 - </B> 4 <B> - </B> 6-trichloro-2-diazo-1-oxybenzene with 1-toluenesulfamido-8-naphthol-4-sulfosate Dye is obtained which, with the help of chrome stains on wool, provides uniform blue nuances that are fast to kneading, light and rubbing.

    <I> Example: </I> The <B> 21,3 </B> parts <B> 3 - </B> 4 <B> - </B> 6-trichloro-9, - amino-l Oxybenzene-prepared diazo compound is allowed to run into an S'Oda-alkaline solution of 39.3 parts of 1-toluenesuliamite-8-naphthol-4-sulfonic acid. The dye is worked up in the usual way.
