  Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden,     da.ss    man einen neuen       wertvollen    metallhaltigen Farbstoff erhält,  wenn man den     Azofa.rbstoff    aus     dia.zotiertem          4-Nitro-2-a.mino-l-phenol        und        2-Amino-5-          oxynaphthalin-7-sulfosäure    mit     kupfera#b-          gebenden    Mitteln und mit einem Oxydations  mittel behandelt, wobei diese beiden Opera  tionen nicht gleichzeitig,

   sondern     naehein-          a.nder        idurahgeführt    werden.  



  Der .erhaltene metallhaltige Farbstoff bil  det getrocknet ein schwarzes Pulver, welches  in Wasser mit     rötlichblauer,    in     verdünnter          Sod,alösung    mit blauroter und in konzentrier  ter Schwefelsäure mit schmutzig blauvio  letter Farbe löslich ist. Er färbt     Baumwolle     aus .alkalischem     Gl.aubersalzbade    in echten       rötlichgrauen    Tönen an.

      <I>Beispiel:</I>         15,4    Teile     dia.zotiertes        4-Nitro-2-.amino-          l.-phenol        werden    auf bekannte Weise mit       23,9    Teilen 2 -     Amino    - 5 -     oxynaphthalin    - 7     -          sulfosä.ure    in alkalischer     Lösung    zum Azo-         farbstoff    kombiniert     und    dieser durch Er  wärmen mit 25 Teilen kristallisiertem Kup  fersulfat in die Kupferverbindung über  geführt.

   Diese wird in 800 Teilen Wasser       unter    Zusatz von 80 Teilen     ,So-da    gelöst     resp-          suspendiert    und im Verlauf mehrerer     Stun-          den    mit einer     Alkalihypochloritlösung,    ent  sprechend 15 Teilen     .aktivam    Chlor versetzt.  Der abgeschiedene Farbstoff wird! durch Um  fällen gereinigt.



  Process for the production of a new metal-containing dye. It has been found that a new valuable metal-containing dye is obtained if the azo dye is obtained from dia.zotierter 4-nitro-2-a.mino-1-phenol and 2-amino-5-oxynaphthalene-7-sulfonic acid treated with kupfera # b- donating agents and with an oxidizing agent, whereby these two operations are not simultaneous

   but to be led closer to one another.



  The obtained metal-containing dye forms a black powder when dried, which is soluble in water with a reddish blue, in dilute soda, a solution with blue-red and in concentrated sulfuric acid with dirty blue-violet color. It dyes cotton from an alkaline magic salt bath in real reddish-gray tones.

      <I> Example: </I> 15.4 parts of dia.zotierter 4-nitro-2-amino-1-phenol are in a known manner with 23.9 parts of 2 - amino - 5 - oxynaphthalene - 7 - sulfosä. ure combined in an alkaline solution to form the azo dye and this by heating it with 25 parts of crystallized copper sulfate into the copper compound.

   This is dissolved or suspended in 800 parts of water with the addition of 80 parts of so-da, and an alkali hypochlorite solution corresponding to 15 parts of active chlorine is added over the course of several hours. The deposited dye will! cleaned by accidents.
