      Zusatzpatent    zum     Hauptpatent    Nr. 212422.         Terfahren    zur Herstellung eines     Trisazofarbstoffes.       Gegenstand des Hauptpatentes ist ein  Verfahren zur Herstellung eines Trisazo-  
EMI0001.0005     
         mit        N-4'-Oxy-3'-carboxyphenyl-l'-sulfonyl-          N    -     methyl-2-amino-5-oxynaphthalin-7-sulfon-          säure    kuppelt.  



  Es wurde nun gefunden, !dass man einen  
EMI0001.0011     
         farbstoffes,    bei dem man die     Diazoverbin-          dung    des     Aminodisazofarbstoffes    der Formel    neuen,     ebenfalls    wertvollen     Trisazofarbstoff          erhält,    wenn man die     Diazoverbindung    des       Aminodisazofarbsto.ffes    der     Formel         mit N-4'-Oxy-3'-carboxyphenyl-1'-sulfonyl       N-methyl-2-a.mino-5-oxynaphthalin-7-sulfon-          säure    (entsprechend der Formel  
EMI0002.0003     
    kuppelt.

    Der neue     Trisazofarbstoff    färbt in blau  grauen Tönen, zieht     substantiv    auf Baum  wolle,     Viskosekunstseide    oder Leinen und  lässt sich im Gemisch mit. Wollfarbstoffen  zum Färben von     Wolle-Baumwolle-    oder       Wolle-Viskosekunstseidemischungen    verwen  den. Die Echtheit der Färbungen kann  durch     Naehheha.ndlung    mit Kupfer- oder  Chromsalzlösungen noch verbessert werden.

         Beispiel:     47,6 Teile     4'-Aminobenzoyl-l-amino-2-          oxy-3-earboxybenzol-5-sulfonsä.ure    werden  dianotiert und in essigsaurer Lösung mit  22,4 Teilen     1-Aminonaphthal.in-7-sulfonsäure     vereinigt. Der erhaltene     Azofarbstoff    wird  
EMI0002.0015     
    mit N-4'-Oxy-3'-carboxyphenyl-1'-sulfonyl       N-methyl-2-amino-5-oxynaphthalin-7-sulfon-          säure    kuppelt.  



  Der neue Farbstoff färbt in blaugrauen  Tönen, zieht     substa.ntiv    auf Baumwolle,     Vis-          kosekunstseide    oder Leinen. Die Echtheit    nun dianotiert, worauf man die     Diazoverbin-          dung    mit 30 Teilen     1-Aminonaphthalin-7-          sulfonsäure    vereinigt.

   Der     Disazofa.rbstoff     wird sodann     ausgesalzen    und     abfiltriert.     Danach löst man ihn in     Na.triumcarbonat-          lösung    und     diazotsert    durch Zugabe von Na  triumnitrit und Eintragen des Gemisches in  verdünnte Salzsäure.

   Die erhaltene     Diazo-          verbindung    wird     abfiltriert    und bei 0   C  in eine mit 60 Teilen     Pyridin    und 57 Tei  len 20%igem Ammoniak versetzte Lösung  von 59 Teilen     N-4'-Oxy-3'-ca-rboxyphenyl-1'-          sulf        onyl    -N-     methyl-2-amino-5-oxynaphthalin-          7-sulfonsäure    eingetragen.  



  Nach Beendigung der Kupplung wird er  hitzt und der     Trisazofarbstoff        ausgesalzen.     Er färbt Baumwolle und     Viskosekunstseide     in blaugrauen Tönen. Durch Nachbehandeln  mit     Chromisalzlösungen    wird eine hervor  ragende Waschechtheit der Färbung erzielt.



      Additional patent to the main patent No. 212422. A method for the production of a trisazo dye. The subject of the main patent is a process for the production of a trisazo
EMI0001.0005
         with N-4'-oxy-3'-carboxyphenyl-1'-sulfonyl-N-methyl-2-amino-5-oxynaphthalene-7-sulfonic acid.



  It has now been found! That one
EMI0001.0011
         dye in which the diazo compound of the aminodisazo dye of the formula new, likewise valuable trisazo dye is obtained when the diazo compound of the aminodisazo dye of the formula with N-4'-oxy-3'-carboxyphenyl-1'-sulfonyl N-methyl -2-a.mino-5-oxynaphthalene-7-sulfonic acid (according to the formula
EMI0002.0003
    clutch.

    The new trisazo dye dyes in blue-gray tones, draws substantive to cotton, viscose artificial silk or linen and can be mixed with. Use wool dyes for dyeing wool-cotton or wool-viscose artificial silk mixtures. The fastness of the dyeings can be further improved by treatment with copper or chromium salt solutions.

         Example: 47.6 parts of 4'-aminobenzoyl-1-amino-2-oxy-3-earboxybenzene-5-sulfonic acid are dianotized and combined with 22.4 parts of 1-aminonaphthalene-7-sulfonic acid in an acetic acid solution. The obtained azo dye is
EMI0002.0015
    with N-4'-oxy-3'-carboxyphenyl-1'-sulfonyl N-methyl-2-amino-5-oxynaphthalene-7-sulfonic acid.



  The new dye dyes in blue-gray tones, applies substa.ntiv to cotton, viscose artificial silk or linen. The authenticity is now dianotized, whereupon the diazo compound is combined with 30 parts of 1-aminonaphthalene-7-sulfonic acid.

   The disazofa dye is then salted out and filtered off. It is then dissolved in sodium carbonate solution and diazotized by adding sodium nitrite and adding the mixture to dilute hydrochloric acid.

   The diazo compound obtained is filtered off and at 0 C in a with 60 parts of pyridine and 57 parts of 20% ammonia mixed solution of 59 parts of N-4'-oxy-3'-ca-rboxyphenyl-1'-sulfonyl - N-methyl-2-amino-5-oxynaphthalene-7-sulfonic acid entered.



  After the coupling has ended, it is heated and the trisazo dye is salted out. He dyes cotton and viscose rayon in blue-gray tones. After-treating with chromium salt solutions, the dyeing is extremely washfast.
