      Verfahren    zur Herstellung eines     direktziehenden        o-Oxyazofarbstofes.       Es wurde gefunden,     class    durch Kuppeln  von     diazotier(er        2-#\iiiiiio-l-o-xyl)eiizol-It-sLilfo-          ,    mit dem Harnstoffe der     ni-Amino--          s    äure       benzoyl-2    :

       5-aminona.lilitol-7-sulfosäui-e    ein  direktziehender     o-Oxyazofas-bstoff    erhalten  wird, welcher Baumwolle in     lieht-    und     al-          lzaliemhfindlichen        rosa    Tönen     anfiirbt.     Durch     Nacliku}ifern    oder noch besser durch  Färben     iii    der für     direktziehende    Farbstoffe  Üblichen Weise unter     Zusatz    von     I@u        l>fer-          verbindungen    zum Bade werden hervor  ragend licht- und     

  alkaliechte        bordeaux    Töne  erhalten.  



       Beispiel:     31,8     1:g        2-Amino-l-oxybenzol-li-sulfosäure          werden    in die     Diazoverbindung    übergeführt  und diese in eine Lösung von 74,2 kg des  auf bekannte Weise durch     Einleiten    von       Phosgen        iu    eine     sodaalkalische    Lösung von       m-Amiriobenzoyl    2 :

       5-aminonaplitol-7-sulfo-          säure    erhaltenen Harnstoffes und 50 kg Soda         einfliessen        ;elassen.    lach 12 Stunden wird  der     Farbstoff        ausg-esaizeri,    filtriert und ge  trocknet.



      Process for the preparation of a substantive o-oxyazo dye. It has been found that by coupling diazotized (er 2 - # \ iiiiiio-l-o-xyl) eiizol-It-sLilfo-, with the urea of the ni-amino acid benzoyl-2:

       5-aminona.lilitol-7-sulfosäui-e a substantive o-oxyazo fiber is obtained, which stains cotton in light and all-easy pink tones. By nacliku} ifern or even better by coloring iii the usual way for substantive dyes with the addition of I @ u l> fer- connections to the bath are excellent light and

  Alkali-like burgundy tones preserved.



       Example: 31.8 1: g of 2-amino-1-oxybenzene-1-sulfonic acid are converted into the diazo compound and this is converted into a solution of 74.2 kg of a soda-alkaline solution of m-amiriobenzoyl in a known manner by introducing phosgene into it 2:

       5-aminonaplitol-7-sulfonic acid obtained urea and 50 kg of soda flow in; After 12 hours, the dye is dried out, filtered and dried.
