  Zusatzpatent zum     IE[auptpatent        Nr.    212421.    Verfahren zur Herstellung eines     Trisazofarbstoffes.       Gegenstand des Hauptpatentes ist ein  Verfahren zur     Ilerstellung    eines neuen Tris-         azoTarbstoffes,    bei dem man     dieDiazoverbin-          dung    des     Aminodisazo#farbstoffes,    der Formel

  Der neue     Trisazofarbstoff    färbt in     grün-          stichig    blauen Tönen, zieht     substantiv    auf  Baumwolle,     Viskosekunstseide    oder Leinen  und     lässt    sich im Gemisch mit     Wollfarbstof-          èn    zum Färben von     Wülle-Baumwolle-    oder       Wolle-Viskosekunstseidemisehungen    verwen  den. Die Echtheit der Färbungen kann  durch     Nachbebündlung    mit Kupfer- oder       Chramsalzlösungen        noeb.    verbessert werden.

      <I>Beispiel:</I>  47,5 Teile     4'-Aminobenzoyl-l-amino-9-          oxy   <B>- 3 -</B>     earboxybenzol-5-sulfons a'ure    werden       diazatiert    und in Gegenwart von Essigsäure  mit 22,4 Teilen     1-Aminonaphthalin-7-sulfon-          säure    vereinigt. Der erhaltene     Aminoazo-          farbstoff    wird sodann     diazotiert    und in         essigsanrer    Lösung mit     13,3    Teilen     1-Amino-          naphthalin    vereinigt.

   Nach Beendigung der  Kupplung wird der     Disazofarbstoff        abfil-          triert,    in     Sodalösun'-,    gelöst und     diazotiert.

  Additional patent to IE [main patent no. 212421. Process for the production of a trisazo dye. The subject of the main patent is a process for the preparation of a new trisazo dye in which the diazo compound of the aminodisazo dye, of the formula
EMI0001.0009
    with N-4'-oxy-3'-carboxyplienyl <B> - </B> 2 <B> - </B> amino-5-oxynaphthalene-7-sulfenic acid in an alkaline medium.



  It has now been found that a new, likewise valuable trisazo dye is obtained if the diazo compound of the amino disazo dye of the formula
EMI0001.0018
      with N-4'-oxy-3'-carboxyphenyl <B> - </B> 2 <B> - </B> amino-5- oxyna.pht # halin-7-sulfonic acid in an alkaline medium.



  The new trisazo dye dyes in green-tinged blue tones, applies substantively to cotton, viscose artificial silk or linen and can be used in a mixture with wool dyes for dyeing Wülle-cotton or wool-viscose artificial silk. The authenticity of the dyeings can be improved by re-bundling with copper or chromium salt solutions. be improved.

      <I> Example: </I> 47.5 parts of 4'-aminobenzoyl-1-amino-9-oxy <B> - 3 - </B> earboxybenzene-5-sulfonic acid are diazated and in the presence of acetic acid combined with 22.4 parts of 1-aminonaphthalene-7-sulfonic acid. The aminoazo dye obtained is then diazotized and combined with 13.3 parts of 1-amino-naphthalene in a solution of acetic acid.

   After the coupling has ended, the disazo dye is filtered off, dissolved in soda solution and diazotized. The diazo compound is then dissolved in a solution of 37.5 parts of N-4'-oxy-3'-earboxyphenyl - </B> 2 - </B> amino <B> - 5 - </B> oxynaphthalene-7-sulfonic acid in 200 parts of water, <B> 55 </B> parts of ammonia and 20 parts of pyridine,

  oil. After the coupling has ended, the mixture is heated and the dye is salted out. He dyes cotton and rayon artificial silk with a green e stiehi.o1- blue shade. The dyeings, which have not been sewn up with chromium salt solution, show very good washability.
