Description

  

      \'erfahren    zur Herstellung eines     direktziehenden        o-Oiyazofarbstoffes.       Es wurde gefunden, dass     dureli        Kuppeln     von dianotierter     2-Amitio-l-oxybenzol-4-sulfo-          säure    mit dem Harnstoffe der     2-Amino-5-oxy-          n.iphtalin-7-sulfosäure    ein direktziehender       o-Oxyazofarbstofferhalteu    wird,     welclierBaum-          wollc    in licht- und ,     alkali-empfindlichen     gelbrosa Tönen anfärbt.

   Durch     Nachkupfern     oder noch besser durch Färben in der für  direktziehende     Farbstoffe    üblichen Weise un  ter     Zusatz    von     Kupferverbindungen    zum Bade  werden hervorragend licht-     arid        alkalieclite     blaurote Töne erhalten.  



       Beispiel:     37,8 kg     2-Ainino-l-ox@#betizol-4-stilfosiitire     werden in die     Diazoverbindting    übergeführt  Lind diese in eine Lösung     voll        50,-1    kg     Harn-          stoff    der     2-Aiiiino-5-oxynaphtalin-7-sulfosäiire          und        501c-    Soda einfliessen gelassen. Nach    12     Stunden    wird der     Farbstoff    aasgesalzen,       filtriert    und getrocknet.



      \ 'experienced in the production of a substantive o-oiyazo dye. It has been found that by coupling dianotated 2-amino-1-oxybenzene-4-sulfonic acid with the urea of 2-amino-5-oxy-n.iphtalin-7-sulfonic acid, a substantive o-oxyazo dye is obtained, welclierTree- wollc dyes in light and alkali-sensitive yellow-pink 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, excellent light-arid alkaline blue-red tones are obtained.



       Example: 37.8 kg of 2-ainino-l-ox @ # betizol-4-stilfosiitire are converted into the diazo compound and this is converted into a solution full of 50.1 kg of urea of the 2-aiiiino-5-oxynaphthalene-7- sulfosäiire and 501c soda allowed to flow in. After 12 hours the dyestuff is salted ashes, filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines direkt ziehenden o-Oxy-tizufai#bsto$es, dadurch ge- kennzE#ichnet, dafj dianotierte 2-Amino-l-o-xy- benzol-4-sulfosiiure mit dem Harnstoffe der An üno-5-oxynaphtalin-7-sulfosäure kombi niert wird. PATENT CLAIM: Process for the production of a direct o-oxy-tizufai # bsto $ es, characterized by the fact that dianotated 2-amino-lo-xy-benzene-4-sulfonic acid with the urea of an uno-5-oxynaphthalene -7-sulfonic acid is combined. Der erhaltene Oxyazofarbstoff färbt direkt Baumwolle in lieht- und alkali- empfindlielien gelbrosa Tönen. Dureli Nach kupfern oder besser durch Färben in der für direktziehende Farbstoffe üblichen Weise un ter Zusatz von Kupfervei#bindungen zum Bade werden hervorragend licht- und alkalieclite blaurote Tune erhalten. The oxyazo dye obtained directly dyes cotton in light- and alkali-sensitive yellow-pink shades. Dureli after copper or better by coloring in the usual way for direct dyes with the addition of copper compounds to the bath, excellent light and alkaline blue-red tones are obtained.
