Description

  

  Verfahren zur Darstellung eines     Trisazofarbstoffes.       Gegenstand vorliegender Erfindung ist  ein Verfahren zur Darstellung eines     Trisazo-          farbstoffes,    dadurch gekennzeichnet, dass man  den     diazotierten        Farbstoff        o-Sulfanilsäure-azo-          1-naphthylamin-    7     -sulfosäure-azo-1-amino    - 2  naphtol-äthyläther-6-sulfosäure mit     rn-Amino-          benzoyl-2-amirro-5-naphtol-7-sulfosäure    in Ge  genwart von     Pyridin    kuppelt.  



  <I>Beispiel:</I>  75,1 Gewichtsteile des     Natriumsalzes    des       Farbstoffes        o-Sulfanilsäure-azo-l-rraphtylamin-          7-sulfosäure-azo-l-amino-    2     -naplitoläthyläther-          6-sulfosäure    werden     diazotiert    und mit 35,8  Gewichtsteilen m-     Aminobenzoyl-2-amino-5-          naphtol-7-sulfosäure    bei Gegenwart von 50  Gewichtsteilen Wasser und 100 Gewichtstei  len     Pyridin    zum     Farbstoff    eiskalt vereinigt.  



  Der in der üblichen Weise isolierte Farb  stoff färbt auf Baumwolle ein Blaugrün. Der         Farbstoff    lässt sich auf der Faser     diazotieren     und mit     Methylphenylpyrazolon    zu einem  echten Grün entwickeln.



  Process for the preparation of a trisazo dye. The present invention relates to a process for the preparation of a trisazo dye, characterized in that the diazotized dye o-sulfanilic acid azo-1-naphthylamine-7-sulfonic acid azo-1-amino-2-naphthol-ethyl ether-6-sulfonic acid with rn-Amino-benzoyl-2-amirro-5-naphthol-7-sulfonic acid in the presence of pyridine.



  <I> Example: </I> 75.1 parts by weight of the sodium salt of the dye o-sulfanilic acid-azo-l-rraphthylamine-7-sulfonic acid-azo-l-amino-2-naplitolethyl ether-6-sulfonic acid are diazotized and 35, 8 parts by weight of m-aminobenzoyl-2-amino-5-naphthol-7-sulfonic acid combined ice-cold in the presence of 50 parts by weight of water and 100 parts by weight of pyridine to form the dye.



  The dye, isolated in the usual way, stains a blue-green on cotton. The dye can be diazotized on the fiber and developed into a real green with methylphenylpyrazolone.
