  Verfahren zur Herstellung eines direktziehenden     o-Oxyazofarbstoffes.       Es wurde gefunden,     dass    durch     Kuppeln     von 1     Mol.        diazotiertem        2-Amino-4-nitro-          1-oxybenzol    und 1     Mol.        diazotiertem        Mono-          acetyl-p-phenylencliamin    mit 1     Mol.        Harn-          stoff    der     2-Amina-5-oxynaphtalin-7-sulfo,

  säure     ein direktziehender     o-Oxyazofarbstoff    erhal  ten wird, welcher Baumwolle in     licht-    und       alkaliempfindlichen    Bordeaux Tönen an  färbt. Durch Nachkupfern oder noch besser  durch Färben in der für direktziehende  Farbstoffe üblichen Weise unter Zusatz von  Kupferverbindungen zum Bade werden her  vorragend licht- und     alkaliechte,        gelbstichig     Bordeaux Töne erhalten.  



  <I>Beispiel:</I>  15,4 kg     2-Amitio-4-nitro-l-oxybenzol    und  15 kg     Monoacetyl-p-phenylendiamin    werden       diazotiert    und diese     nacheinander    in eine  Lösung von 50,4     k4    Harnstoff der     2-Amino-          5-oxynaplitalin-7-sulfosätii-e    und 50 kg Soda    einfliessen gelassen. Nach 1.2 Stunden wird  der Farbstoff     ausgesalzen.    filtriert und ge  trocknet.



  Process for the preparation of a substantive o-oxyazo dye. It was found that by coupling 1 mole of diazotized 2-amino-4-nitro-1-oxybenzene and 1 mole of diazotized monoacetyl-p-phenylene cliamine with 1 mole of urea, the 2-amina-5-oxynaphthalene -7-sulfo,

  acid a substantive o-oxyazo dye is obtained, which dyes cotton in light- and alkali-sensitive Bordeaux 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- and alkali-fast, yellowish Bordeaux tones are obtained.



  <I> Example: </I> 15.4 kg of 2-amino-4-nitro-1-oxybenzene and 15 kg of monoacetyl-p-phenylenediamine are diazotized and these are successively converted into a solution of 50.4 k4 of urea of the 2-amino - Let 5-oxynaplitalin-7-sulfosätii-e and 50 kg of soda flow in. After 1.2 hours, the dye is salted out. filtered and dried.
