      \'erfahren    zur Herstellung eines     direktziehenden        o-OYyazofau'bstoffes.       Es wurde     gefunden,    dass durch Kuppeln  von 1     Mol.        diazotierte.r        p-Aminoazobeiizol-          sulfosäure    und 1     Mol.        diazotiertein        2-Amino-          4-nitro-l-oxybenzol    mit 1     Mol.    Harnstoff     dei-          2-Amiiio-5-oxyiiaphtalin-7-sulfosäur    e ein di  rektziehender     o-Oxyazofarbstoff   

       ei halten     wird, welcher Baumwolle in licht- und     al-          kaliempfindlichen    violetten Tönen anfärbt.  Durch     Nachkupfern    oder noch besser     durch          Färben    in     cler    für     clirektziehende        Farbstoffe     üblichen Weise     unter    Zusatz von     1iupferver-          bindungen        zum    Bade weiden hervorragend  licht- und     alkalieclite        gelbbordeaux    Töne er  halten.  



       Beispiel:          30    kg     1)-Aniinoazobenzolsulfosäure    und  15,4 kg     2-.Xmino--i-nitro-l-oxylieiizol    werden       diazotiert    und diese     nacheinanclei-    in eine  Lösung von     50,4    kg Harnstoff der     2-Amino--          5-oxynaplitalin-7-sulfosäure    und 50 kg     Soda     einfliessen     gelassen.

      \ 'experienced for the production of a substantive o-OYyazo dye. It has been found that by coupling 1 mole of diazotized p-aminoazobeiizole sulfonic acid and 1 mole of diazotized 2-amino-4-nitro-1-oxybenzene with 1 mole of urea dei-2-amino-5-oxyiiaphthalene 7-sulfonic acid is a direct o-oxyazo dye

       egg, which dyes cotton in light- and alkali-sensitive violet tones. By re-coppering or, even better, by dyeing in the manner customary for direct dyes with the addition of copper compounds to the bathing willow, excellent light and alkaline yellow-bordeaux tones are obtained.



       Example: 30 kg of 1) -aniinoazobenzenesulfonic acid and 15.4 kg of 2-.Xmino-i-nitro-l-oxylieiizole are diazotized and these are successively converted into a solution of 50.4 kg of urea of 2-amino-5-oxynaplitalin -7-sulfonic acid and 50 kg of soda are allowed to flow in. After 12 hours, eler dye is salted out, filtered and dried.
