  <I>Beispiel:</I>       33,7    Teile     3-Amino-4'-ogy-1    :     1'-a,zobenzol-          3'    -     carbonsäure    - 4 -     sulfonsäure    werden, nach  dem aus der schweizerischen Patentschrift  Nr.     1750,2.9        bekannten    Verfahren     diazotiert     und in essigsaurer Lösung mit     2'3,9        Teilen        2-          Amino-5-ogynaphthalin-7-sulfonsäure    gekup  pelt.

   Dann     wird,der    erhaltene     Disazofarbstoff     in alkalischer     Lösung    mit der     Diazoverbin-          dung    aus     23,3.    Teilen 2-Amino-l-ogy-benzol-         6-carbonsäure-4-,sulfonsäure        weiter    gekuppelt.

    Nach     beendeter    Kupplung wird der     erhaltene          Trisazo-farbstoff        ausgesalzen,        abgenutscht,    in       20'0O    Teilen     heissem    Wasser gelöst und diese  Lösung mit     einer        wässerigen    Lösung von 25  Teilen     kristallisiertem    Kupfersulfat versetzt.  Die     rotbraune    Fällung wird während einer.

    Stunde bei 90   C     gerührt    und die Ausfäl  lung der     Kupferverbindung    durch     Zusatz     von     Kochsalz    beendet.     Durch    Kochen     einer     Lösung der Kupferverbindung bei     Gegen-          wart    von Alkali kann, wenn nötig,     eventuell     nicht     komplex        gebundenes        Kupfer    gefällt  werden.

  Process for the production of a new, metal-containing stain dye. It has been found that a new, copper-containing mordant dye is obtained if a molecule of 2-amino-5-oxynaphthalene-7-sulfonic acid is first added to a weakly acid medium with a molecule of diazotized amino-4'-ogy-1:

       1'-azo @ benzene-3'-carboxylic acid-4-sulphonic acid and then in a weakly alkaline medium with a molecule of diazotized 2-amino.-l-ogybenzene-6-carboxylic acid-4-sulphonic acid and: the obtained tris azo dye is treated with a copper-releasing substance.



  <I> Example: </I> 33.7 parts of 3-Amino-4'-ogy-1: 1'-a, zobenzene- 3 '- carboxylic acid - 4 - sulfonic acid, according to the Swiss patent no. 1750 , 2.9 known processes and diazotized in acetic acid solution with 2'3.9 parts of 2-amino-5-ogynaphthalene-7-sulfonic acid gekup pelt.

   Then the disazo dye obtained is in alkaline solution with the diazo compound from 23.3. Share 2-amino-l-ogy-benzene-6-carboxylic acid-4-, sulfonic acid further coupled.

    After the coupling has ended, the trisazo dye obtained is salted out, filtered off with suction, dissolved in 20,000 parts of hot water and this solution is treated with an aqueous solution of 25 parts of crystallized copper sulfate. The red-brown precipitation is during a.

    Stirred for an hour at 90 ° C. and the precipitation of the copper compound was terminated by adding sodium chloride. By boiling a solution of the copper compound in the presence of alkali, if necessary, copper that is not complexly bound can be precipitated.



  The new, copper-containing dye forms a dark brown powder when dried, dissolves in water with a reddish brown color, in concentrated sulfuric acid with a yellowish brown color and, when printed on chrome on cotton, artificial silk made from regenerated cellulose or natural silk, produces reddish brown tones.
