Description

  

      Verfahren    zur Herstellung eines     direktziehenden        o-Oiyazofarbstoffe,.       Es wurde gefunden, dass durch Kuppeln  von     diazotiertem        2-Amino-5-nitro-l-oxyben-          zol    mit     m-Aminobe,rizoyl-2:5-aminonaphtol-          i-sulfosäure    ein direktziehender     o-Oxyazo-          farbstoff    erhalten wird, welcher Baumwolle  in licht- und     alkaliempfin.dlichen    violetten  Tönen anfärbt.

   Durch Nachkupfern oder  noch besser durch Färben in der für direkt  ziehende Farbstoffe üblichen Weise unter  Zusatz von     Kupferverbindungen        zum    Bade  werden     hervorra@:end    licht- und     alkalieclite     graue Töne erhalten.

           Beispiel:       15,4 kg     2-Amino-5-nitro-1-oxybenzol    wer  den in die     Diazowerbindung        übergeführt    und  diese in eine Lösung von 37     kg        m-Amino-          benzoyl=?        :i)aniiiioriaphtol-7-sulfosäure        und     30 kg Soda     einfliessen        gelassen.        Nach    1          Stunden        wird    der Farbstoff     aasgesalzen,     filtriert, und getrocknet



      Process for the preparation of a substantive o-olyazo dye. It has been found that by coupling diazotized 2-amino-5-nitro-1-oxybenzene with m-aminobe, rizoyl-2: 5-aminonaphthol-1-sulfonic acid, a substantive o-oxyazo dye is obtained, which is cotton colors in light- and alkali-sensitive violet tones.

   By re-coppering or, even better, by dyeing in the manner customary for direct dyestuffs with the addition of copper compounds to the bath, excellent light and alkaline gray tones are obtained.

           Example: 15.4 kg of 2-amino-5-nitro-1-oxybenzene are converted into the diazo bond and this is converted into a solution of 37 kg of m-amino-benzoyl =? : i) aniiiioriaphtol-7-sulfonic acid and 30 kg of soda are allowed to flow in. After 1 hour, the dyestuff is washed with salt, filtered and dried

PATENTANSPRUCH: Verfahren zur Herstellung eines direkt- ziehenden o-Oxyazofa.rbstoffes, dadurch ge kennzeichnet, class diazotiertes 2-Amino-5- iiitro-l-oxybenzol mit ziii-Aminobenzoyl-2- : 5- Aminoiial,ht.ol-7-sulfosiiui-e kombiniert wird. PATENT CLAIM: Process for the production of a direct o-oxyazofa dye, characterized in that class diazotized 2-amino-5-nitro-1-oxybenzene with ziii-aminobenzoyl-2-: 5- aminoiial, ht.ol-7- sulfosiiui-e is combined. Der erhaltene Oxvazofarbstoff färbt. direkt Baumwolle in licht- und alkaliempfind- lichen violetten Tönen. Durch Nachkupfern oder besser durch Färben in der für direki- ziehende Farbstoffe üblichen Weise unter Zusatz von Kupferverbindungen zum Bade werden hervorragend iiclit- und alkaliechte ;raue Töne erhalten. The oxvazo dye obtained stains. directly cotton in light- and alkali-sensitive violet tones. By re-coppering or, better still, by dyeing in the manner customary for directing dyes with the addition of copper compounds to the bath, outstandingly white and alkali-fast, rough tones are obtained.
