Description

  

  Verfahren zur     Herstelluug    eines für den     CVromdruek    auf Baumwolle besonders  geeigneten     Azofarbstoffes.       Es wurde gefunden,     d.a,ss    man durch Kup  peln von zwei     Mol.        dia.zotiertem        4-Nirto-2-          .        ani        .ino-l-oxybenzol        mit        einem        Mol.        Resorcyl-          s#iure    einen     Azoàrbstoff    erhält, welcher bei       dF:

  ni    Chromdruck auf Baumwolle violett  braune Töne von guten     Echtheiten    erzeugt.         Beispiel:       Die     Diazoverbindung    aus 15,4 Teilen     4-          Nitro-2-amino-l-oxybenzol    lässt man in eine  Lösung von 7,7 Teilen     Resorcylsäure    und  30 Teilen Soda einfliessen. Der     gebildete     Farbstoff wird durch Fällen mit Kochsalz       abgeschieden.     



  Der neue Farbstoff bildet ein dunkles  Pulver, welches sich in Wasser mit rot  brauner Farbe löst, welche Lösung .auf Zu  satz von Soda, etwas röter     wird.    In konzen  trierter Schwefelsäure ist er mit rotbrauner  Farbe löslich. Im     Chromdru.ek    ,auf Baum-    wolle erzeugt er     violettbraune    Töne von gu  ten     Echtheiten.  



  Process for the production of an azo dye which is particularly suitable for CVromdruek on cotton. It has been found that by coupling two moles of dia.zotierter 4-Nirto-2-. ani .ino-l-oxybenzene with one mole of resorcylic acid gives an azo dye, which at dF:

  ni chrome print on cotton produces violet-brown shades of good fastness properties. Example: The diazo compound from 15.4 parts of 4-nitro-2-amino-1-oxybenzene is allowed to flow into a solution of 7.7 parts of resorcylic acid and 30 parts of soda. The dye formed is deposited by precipitating with common salt.



  The new dye forms a dark powder which dissolves in water with a red-brown color, which solution becomes a little redder with the addition of soda. It is soluble in concentrated sulfuric acid with a red-brown color. In Chromdru.ek, on cotton, it creates violet-brown tones with good fastness properties.

PATENT CLAIM Process for the production of an azo dye particularly suitable for chrome printing on cotton; characterized in that two moles of di.azotized 4-nitro-2-amino-1-oxyberizole are coupled with one mole of resorcylic acid. Der neue Farbstoff bildet ein dunkles Pulver, welches sich in Wasser mit rot brauner Farbe löst, welche Lösung auf Zu satz von Soda etwas röter wird. In konzen trierter Schwefelsäure ist er mit rotbrauner Farbe löslich. Im Chromdruck auf Baum wolle erzeugt er violetthraune Töne von gu ten Echtheiten. The new dye forms a dark powder, which dissolves in water with a red-brown color, which solution becomes a little redder with the addition of soda. It is soluble in concentrated sulfuric acid with a red-brown color. In chrome printing on cotton, it creates violet-lime tones with good fastness properties.
