  <B>Zusatzpatent</B> zum Hauptpatent Nr. 212422.    Verfahren zur Herstellung eines     Trisazofarbstoffes.       Gegenstand des Hauptpatentes     ist    ein  Verfahren zur Herstellung eines Trisazo-  
EMI0001.0003     
    mit     N-4'-Oxy-3'-earboxyphenyl-1'-sulfonyl-          N    -     methyl-2-amino-5-oxynaphthalin-7-sulf        on-          säure    kuppelt.

         farbstoffes,    bei dem man .die     Diazoverbin-          dung    des     Aminodisazofarbstoffes    der Formel    Es wurde nun gefunden,     dass    man einen  neuen, ebenfalls wertvollen     Trisazofarbstoff     erhält,

   wenn man die     Diazoverbindung    des       Aminodisazofarbstoffes    der Formel      mit     N-4'-Oxy-3'-carboxyphenyl-1'-sulfonyl-          N-        methyl-2-amino-5-oxynaphtha.lin-7-sulf        on-          säure    (entsprechend der Formel  
EMI0002.0006     
    kuppelt.

    Der neue     Trisazofarbstoff    färbt. in grü  nen Tönen, zieht     substantiv    auf Baumwolle,       Viskoseseide    und Leinen und lässt sich im  Gemisch mit Wollfarbstoffen zum Färben  von     Wolle-Baumwolle-    oder     Wolle-Viskose-          kunstseidemischungen    verwenden. Die Echt  heit der Färbungen kann durch Nachbehan  deln mit Kupfer- oder Chromsalzlösungen       noch    verbessert werden.  



  <I>Beispiel:</I>  Man kuppelt die     Diazoverbindung    aus  352 Teilen     3'-Aminobenzoyl    - 1 -     amino    - 3     -          ca.rboxy-4-oxybenzol-5-sulfonsäure    mit 189  Teigen     i    - (4'-     Aminophenyl)-3-methyl-5-py    r  a.zolon unter Zugabe von     Natriumacetat.    Nach    Beendigung der     Farbstoffbildung    löst man  die ockergelbe Masse mit Natronlauge auf,  setzt 69     Teile        Natriumnitrit    zu und lässt bei  15   C langsam bis zur schwach sauren  Reaktion Salzsäure zulaufen.

   Man rührt. die  dicke     ora.ngebraune    Masse einige Stunden  lang nach und setzt dann eine neutrale Lö  sung von 267 Teilen     1-Amino-2-äthoxynaph-          thalin-6-sulfonsäure    hinzu. Die Kupplung  wird unter Zusatz von     Natriumacetat    zu  Ende geführt. Sodann löst man. die Farb  säure mit     Natronlauge,    salzt aus und saugt  den     Disazofarbstoff    ab. Darauf nimmt man  mit Wasser auf, setzt 69 Teile Natrium  nitrit hinzu und     diazotiert    bei etwa 8   C  durch langsame Zugabe von Salzsäure.

   Da  nach kuppelt man mit 453 Teilen     N-4'-Oxy-          3'-        earboxyphenyl    -1'-     sulfonyl    - N -     methyl    -     2-          amino    - 5 -     oxynaphthalin    - 7 -     sulfonsä,ure    in       ammoniakalischer,        pyridinhaltiger    Lösung.



  <B> Additional patent </B> to main patent no. 212422. Process for the production of a trisazo dye. The subject of the main patent is a process for the production of a trisazo
EMI0001.0003
    with N-4'-oxy-3'-earboxyphenyl-1'-sulfonyl-N-methyl-2-amino-5-oxynaphthalene-7-sulfonic acid.

    
EMI0001.0009
         dye in which one .die diazo compound of the amino disazo dye of the formula It has now been found that a new, likewise valuable trisazo dye is obtained,

   if the diazo compound of the aminodisazo dye of the formula with N-4'-oxy-3'-carboxyphenyl-1'-sulfonyl-N-methyl-2-amino-5-oxynaphtha.lin-7-sulfonic acid (corresponding to the formula
EMI0002.0006
    clutch.

    The new trisazo dye stains. in green tones, draws substantive to cotton, viscose silk and linen and can be used in a mixture with wool dyes to dye wool-cotton or wool-viscose rayon blends. The authenticity of the colorations can be improved by post-treating with copper or chromium salt solutions.



  <I> Example: </I> The diazo compound is coupled from 352 parts of 3'-aminobenzoyl - 1 - amino - 3 - about rboxy-4-oxybenzene-5-sulfonic acid with 189 doughs i - (4'-aminophenyl) - 3-methyl-5-py r a.zolon with addition of sodium acetate. When the dye formation has ended, the ocher-yellow mass is dissolved with sodium hydroxide solution, 69 parts of sodium nitrite are added and hydrochloric acid is slowly added at 15 ° C. until a weakly acidic reaction occurs.

   One stirs. the thick orange-brown mass for a few hours and then adds a neutral solution of 267 parts of 1-amino-2-ethoxynaphthalene-6-sulfonic acid. The coupling is brought to an end with the addition of sodium acetate. Then you solve. the color acid with sodium hydroxide solution, salt out and sucks off the disazo dye. It is then taken up in water, 69 parts of sodium nitrite are added and the mixture is diazotized at about 8 ° C. by slowly adding hydrochloric acid.

   Then coupling is carried out with 453 parts of N-4'-oxy-3'-earboxyphenyl -1'-sulfonyl-N-methyl-2-amino-5-oxynaphthalene-7-sulfonic acid in an ammoniacal, pyridine-containing solution.
