Description

  

  Verfahren zur     Herstellung    eines     direktziehenden        o-Uz3-azofarbstoffes.       Es wurde     gefunden,    dass durch Kuppeln  von 1     b1ol.        diazotiertein    Anilin und     11\1o1.     dianotiertem     2-Amino-4-Nitro-l-oxybei@zol    mit  1     11Io1.    Harnstoff der     2-Aniitro-5-oxyriaphtalirt-          7-sulfosäure    ein direktziehender     o-Oxyazo-          farbstoff    erhalten wird,

   welcher Baumwolle  in licht- und     alkaliempfindlichen        bordeaux     Tönen anfärbt. Durch     Nachkupfern    oder noch  besser durch Färben in der für     direktziehende          Farbstoffe    üblichen     Weise    unter Zusatz     von     Kupferverbindungen zum Bade werden leer  vorragend licht- und     alkaliechte        gelbbordeaux     Töne erhalten.

      <I>Beispiel:</I>  9,3 kg Anilin und     15,4    kg     2-Atitino-4-          nitro-l-oxybenzol    werden dianotiert und diese  nacheinander in eine Lösung von 50,4 kg       Harnstoff    der     2-Aniiiio-5-oxytiaphtalin-7-stilfo-          säure    und 50 kg Soda einfliessen gelassen.    Nach 12 Stunden wird der     Farbstoff'        ausge-          salzen,    filtriert     lind    getrocknet.



  Process for the production of a substantive o-Uz3-azo dye. It was found that by coupling 1 b1ol. diazotized in aniline and 11 \ 1o1. dianotated 2-amino-4-nitro-1-oxybei @ zol with 11101. Urea of 2-Aniitro-5-oxyriaphtalirt- 7-sulfonic acid a substantive o-oxyazo dye is obtained,

   which dyes cotton in light- and alkali-sensitive burgundy tones. By re-coppering or, even better, by dyeing in the manner customary for substantive dyes with the addition of copper compounds to the bath, light- and alkali-fast yellow-burgundy shades that protrude empty are obtained.

      <I> Example: </I> 9.3 kg of aniline and 15.4 kg of 2-atitino-4-nitro-1-oxybenzene are dianotized and these are successively converted into a solution of 50.4 kg of urea of the 2-aniiiio-5 -oxytiaphtalin-7-stilfoic acid and 50 kg of soda are allowed to flow in. After 12 hours, the dye is salted out, filtered and dried.

Durch Nachkupfern oder besser durch Färben in der für direkt ziehende Farbstoffe üblichen Weise unter Zusatz von Kupferverbindungen zum Bade werden hervorragend licht- und alkaliechte gelbbordeaux Töne erhalten. The oxyazo dye obtained directly dyes cotton in light- and alkali-resistant shades of burgundy. By re-coppering or, better, by dyeing in the manner customary for direct dyes with the addition of copper compounds to the bath, excellent light- and alkali-fast yellow-bordeaux tones are obtained.
