  Verfahren zur Herstellung eines kupferhaltigen     Trisazofarbatoffes.       Die vorliegende Erfindung betrifft ein  Verfahren zur Herstellung eines kupferhal  tigen     Trisazofarbstoffes,    welches darin besteht,  dass man 1     11o1        5,5'-Dioxy-2,2'-dinaphthyl-          amin-7,7'-disulfonsäure,    1     1Iol        tetrazotiertes          3,3'-Dimethoxy-4,4'-diaminodiphenyl,    1     Mol        1-          Oxynaphthalin-3,

  6-disulfonsäure    und 1     Mol          diazotierte        4-Nitro-2-amino-l-ox3,benzol-6-sul-          fonsäure    derart aufeinander einwirken lässt,  dass das     3,3'-Dinietlioxy-4,4'-tetrazodiphenyl     einerseits in     2-Stellung    der     1-Oxynaphthalin-          3,6-disulfonsäure    und anderseits in     6-Stellung     der     5,5'-Dioxy-2,2'-dinaphthylamin-7,

  7'-disul-          fonsäure        lind    die     4-Nitro-2-diazo-l-oxybenzol-6-          sulfonsäure    in     6'-Stellung    der     5,5'-Dioxy-2,2'-          dinaplit.hylamin-7,7'-disulfonsäure    eingreifen,  und den erhaltenen     Trisazofarbstoff    mit einem  kupferabgebenden Mittel behandelt.  



       Beispiel:     21,4 Teile     3,3'-Dimethoxy-4,4'-cliainino-          diphenyl    werden wie üblich     tetrazotiert    und  die     Tetrazoverbindung    hierauf unter Eisküh  lung mit 30,4 Teilen     1-Oxynaphtlialin-3,6-di-          sulfonsäure    in Gegenwart von Soda ver  einigt.. Nach erfolgter Bildung der     Zwi-          sehenverbind'ung    wird diese in     sodaalkalischein     Mittel mit 46,1 Teilen     5,5'-Dioxy-2,2'-dinaph-          thylamin-7,7'-disulfonsäure    gekuppelt.

   Der  entstandene     Disazofarbstoff    wird filtriert,  unter Zusatz von Soda und     Wasser    gelöst und  in Gegenwart von 5 bis 10     Vol.II/o        Pyridin-          basengemisch    mit der in üblicher Weise her  gestellten     Diazoverbindung    von 23,4 Teilen         4-Nitro-2-amino-l-oxybenzol-6-sulfonsäure    ver  einigt.  



  Der isolierte     Trisazofarbstoff    wird mit       Kupferoxy        dammoniaklösung    auf bekannte  Weise in die     Kupferkomplexverbindtmg    über  geführt. Der neue Farbstoff färbt Baumwolle  und Fasern aus regenerierter     Cellulose    in  lebhaft blauen Tönen von sehr guter     Lieht-          und    Waschechtheit.



  Process for the production of a copper-containing trisazo carbate. The present invention relates to a process for the preparation of a kupferhal term trisazo dye, which consists of 1 11o1 5,5'-dioxy-2,2'-dinaphthylamine-7,7'-disulfonic acid, 1 1Iol tetrazotized 3,3 '-Dimethoxy-4,4'-diaminodiphenyl, 1 mole of 1-oxynaphthalene-3,

  6-disulfonic acid and 1 mole of diazotized 4-nitro-2-amino-1-ox3, benzene-6-sulfonic acid can act on one another in such a way that the 3,3'-dinietlioxy-4,4'-tetrazodiphenyl on the one hand in 2- Position of 1-oxynaphthalene-3,6-disulfonic acid and, on the other hand, in 6-position of 5,5'-dioxy-2,2'-dinaphthylamine-7,

  7'-disulfonic acid and the 4-nitro-2-diazo-1-oxybenzene-6-sulfonic acid in the 6'-position of the 5,5'-dioxy-2,2'-dinaplit.hylamine-7,7'- intervene disulfonic acid, and treated the obtained trisazo dye with a copper donor.



       Example: 21.4 parts of 3,3'-dimethoxy-4,4'-cliainino-diphenyl are tetrazotized as usual and the tetrazo compound is then mixed with 30.4 parts of 1-oxynaphthalene-3,6-disulfonic acid in the presence of ice-cooling united by soda. After the intermediate compound has formed, it is coupled in an alkaline soda agent with 46.1 parts of 5,5'-dioxy-2,2'-dinaphthylamine-7,7'-disulfonic acid.

   The resulting disazo dye is filtered, dissolved with the addition of soda and water and in the presence of 5 to 10 Vol.II / o pyridine base mixture with the diazo compound of 23.4 parts of 4-nitro-2-amino-l prepared in the usual way -oxybenzene-6-sulfonic acid united ver.



  The isolated trisazo dye is converted into the copper complex compound in a known manner using copper oxy ammonia solution. The new dye dyes cotton and fibers made from regenerated cellulose in lively blue tones with very good light and wash fastness.
