Description

  

  Verfahren zur Herstellung eines     o-Ogyazofarbstoffes.       Nach dem im Hauptpatent beschriebenen  Verfahren erhält man einen Wolle in Gegen  wart einer Chrombeize in blaugrünen Tönen  anfärbenden o -     Oxyazofarbstoff,    wenn man       2-Amitio-l-oxybenzol        diazotiert    und die     Diazo-          verbindung    mit     1-Phenylamino-8-ogynaphtha-          lin-4-sulfosäure    kuppelt.  



  Wie nun weiter gefunden wurde, erhält  man einen ähnlichen Farbstoff, wenn man       4-9ethyl-6-nitro-2-amino-l-ogybenzol        diazo-          tiert    und die     Diazoverbindung    mit 1-(2'       Methoxy-phenyl)-arnino-8-oxynaphthalin-4-          sulfosäure    kuppelt.    <I>Beispiel:</I>  168 Teile     4-Methyl-6-nitro-2-amino-l-oxy-          benzol    werden     diazotiert    und mit 362 Teilen         1-(2'-Methoxy-phenyl)-amirio-8-oxynaphthalin-          4-sulfosäure    in     sodaalkalischer    Lösung kom  biniert.

   Man erhält, auf Wolle mit     Meta-          chrombeize    gefärbt, ein Grün.



  Process for the preparation of an o-ogyazo dye. The process described in the main patent gives a wool in the presence of a chrome stain in blue-green shades of o - oxyazo dye, if 2-amitio-1-oxybenzene is diazotized and the diazo compound with 1-phenylamino-8-ogynaphthalin-4 -sulfonic acid couples.



  As has now been found, a similar dye is obtained if 4-9ethyl-6-nitro-2-amino-1-ogybenzene is diazo- and the diazo compound is treated with 1- (2 'methoxyphenyl) -amino-8- oxynaphthalene-4-sulfonic acid couples. <I> Example: </I> 168 parts of 4-methyl-6-nitro-2-amino-1-oxy-benzene are diazotized and mixed with 362 parts of 1- (2'-methoxyphenyl) -amirio-8-oxynaphthalene - 4-sulfonic acid combined in a soda-alkaline solution.

   When the wool is dyed with metachrome stain, a green is obtained.

PATENTANSPRUCH: Verfahren zur Herstellung eines o - Oxy- azofarbstoffes, dadurch gekennzeichnet, da13 man 4-Methyl-6-nitro-2-amino-l-oxybenzol diazotiert und die Diazoverbindung mit 1 (2'-Methoxy-phenyl)-amino-8-oxynaphthalin.4- sulfosäure kuppelt. Mit Metachrombeize wird auf Wolle ein Grün erhalten. Claim: Process for the production of an o-oxy azo dye, characterized in that 4-methyl-6-nitro-2-amino-1-oxybenzene is diazotized and the diazo compound is diazotized with 1 (2'-methoxyphenyl) -amino-8 -oxynaphthalene.4- sulfonic acid couples. With Metachrome stain a green is obtained on wool.
