Description

  

  Verfahren zur Herstellung eines     direktziehenden        o-Osyazofarbstoffes.       Es wurde     gefunden,    dass durch Kuppeln  von     diaz.otiertem        2-Aniino-4-clilor-l-oxyberi-          zol    mit dem Harnstoffe der     2-Amino-5-oxy-          naphtalin-7-sulfosäure    ein     direktziehender          o-Oxyazofarbstoff    erhalten wird, welcher  Baumwolle in licht- und     alkaliempfind-          lichen,    gelbrosa Tönen anfärbt.

   Durch Nach  kupfern oder noch besser durch Färben in  der für direktziehende Farbstoffe     üblichen     Weise unter Zusatz von     Kupferverbindun-          gen    zum Bade werden hervorragend     liclit-          und        alkaliechte    blaurote Töne     erhalten.     



  <I>Beispiel:</I>       28,7    kg     2-Amirio-4-chlor-l-oxyberizol    wer  den in die     Diazoverbindung    übergeführt und  diese in eine Lösung von 50,4 kg Harnstoff  der     2-Amino-5-oxynaphtalin-7-sulfosäure        und     50 kg Soda einfliessen gelassen. Nach 12         Stunden    wird der Farbstoff     a-usgesalzen,    fil  triert     und    getrocknet.



  Process for the production of a substantive o-osyazo dye. It has been found that by coupling diaz.otosed 2-aniino-4-clilor-1-oxyberizole with the urea of 2-amino-5-oxynaphthalene-7-sulfonic acid, a substantive o-oxyazo dye is obtained, which Dyes cotton in light- and alkali-sensitive, yellow-pink tones.

   After coppering or, even better, coloring in the manner customary for substantive dyes with the addition of copper compounds to the bath, excellent licit- and alkali-fast blue-red tones are obtained.



  <I> Example: </I> 28.7 kg of 2-amirio-4-chloro-l-oxyberizole are converted into the diazo compound and this is converted into a solution of 50.4 kg of urea of the 2-amino-5-oxynaphthalene- 7-sulfonic acid and 50 kg of soda are allowed to flow in. After 12 hours, the dye is salted out, filtered and dried.
