  Verfahren zur Herstellung eines neuen metallhaltigen     Polyazofarbstoffes.       Es wurde gefunden,     da13    man einen neuen  metallhaltigen     Polyazofarbstoff    erhält, wenn  man     den;        Mou.oazo@farbsto:

  ff    aus 1     Mol.        5,5'-Di-          oxy-2,2'-dinaphthylamin-7,7'-disulfosäure    und  1     Mol.        diazotiertemf        4-Chlor-2-amino-l-phenol     mit kupferabgebenden Mitteln behandelt,

   die er  haltene     Komplexkupferverbindung    weiter mit  1     Mol.        diazotiertem        4-Chlor-2-amino-l-phenol     kuppelt und die     entstandene    Kupferverbin  dung des     Dsazofarbstoffes    bis zur voll  ständigen Sättigung der     metallisierbaren     Gruppen mit kupferabgebenden Mitteln wei  terbehandelt.  



  Der neue Farbstoff löst sich in Wasser  und in 10     %iger        Sodalösung    oder Natron  lauge mit rotvioletter und in konzentrierter  Schwefelsäure mit     schwärzlichblauer    Farbe.  Er färbt Baumwolle aus neutralem oder alka  lischem Färbebad violett.    <I>Beispiel:</I>  46,1 Teile     5,5'-Dioxy-2,2'-dinaphthyl-          amin-7,7'-disulfosäure    werden in<B>709</B> Teilen    Wasser zusammen mit 30 Teilen Soda gelöst  und mit der     Diazolösung    aus 14;3 Teilen     4-          Chlor-2-amino-l-phenol    kombiniert.

   Der durch       Aussalzen    wie üblich aufgearbeitete rote  Farbstoff wird in 6000 Teilen Wasser  heiss gelöst und mit 25     Teilen.    Kupfersulfat  in     Form    einer     konzentrierten]    Lösung versetzt  und eine     Viertelstunde        unter    Rühren auf dem  Wasserbad     erwärmt.    Der Farbstoff nimmt  dabei eine violette Nuance an und wird durch       Kochsalz        quantitativ    abgeschieden.

   In Was  ser und     konzentrierter,S'chwefelsäure    löst er  sich     violett,    in     Sodalösung    oder verdünnter       Ätzalkalilauge    blaurot. Er färbt Baumwolle  aus     glaubersalzhaltigem    Färbebad rotviolett       .an.     



  Der neue Farbstoff wird nun in 1000 Tei  len einer 5     %igen        Sodalösung    gelöst     resp.          suspendiert    und     weiterhin    mit der     Diazo-          lösung    aus 14,3 Teilen     4-Chlor-2-amino-l-          phenol    gekuppelt.

   Die     wie    üblich     isolierte          Monokupferverbindung    wird nun in 6000  Teilen Wasser heiss gelöst, mit einer kon-           zentrierten    Lösung     aus    25 Teilen Kupfer  sulfat versetzt und eine     Stunde    auf dem  Wasserbad     erwärmt.    Die gebildete Kupfer  verbindung wird hierauf wie üblich isoliert  und getrocknet. Sie färbt Baumwolle aus  neutralem oder alkalischem Färbebad violett.



  Process for the preparation of a new metal-containing polyazo dye. It has been found that a new metal-containing polyazo dye is obtained if the; Mou.oazo@farbsto:

  ff treated from 1 mol. 5,5'-dioxy-2,2'-dinaphthylamine-7,7'-disulfonic acid and 1 mol. diazotized 4-chloro-2-amino-1-phenol with copper-releasing agents,

   he obtained complex copper compound further coupled with 1 mol. Diazotized 4-chloro-2-amino-l-phenol and the resulting copper compound of the disazo dye is further treated with copper-donating agents until the metallizable groups are completely saturated.



  The new dye dissolves in water and in 10% soda solution or caustic soda with red-violet and in concentrated sulfuric acid with a blackish-blue color. It dyes cotton from a neutral or alkaline dye bath purple. <I> Example: </I> 46.1 parts of 5,5'-dioxy-2,2'-dinaphthylamine-7,7'-disulfonic acid are added to <B> 709 </B> parts of water together with 30 Parts of soda dissolved and combined with the diazo solution of 14; 3 parts of 4-chloro-2-amino-1-phenol.

   The red dye, worked up by salting out as usual, is dissolved in 6000 parts of hot water and then added to 25 parts. Copper sulfate in the form of a concentrated] solution and heated for a quarter of an hour while stirring on the water bath. The dye takes on a violet shade and is quantitatively deposited by table salt.

   In water and concentrated sulfuric acid it dissolves violet, in soda solution or dilute caustic lye it dissolves blue-red. He dyes cotton from a dyebath containing Glauber's salt red-violet.



  The new dye is now dissolved in 1000 parts of a 5% soda solution, respectively. suspended and further coupled with the diazo solution of 14.3 parts of 4-chloro-2-amino-1-phenol.

   The monocopper compound isolated as usual is then dissolved in 6000 parts of hot water, mixed with a concentrated solution of 25 parts of copper sulfate and heated for one hour on a water bath. The copper compound formed is then isolated and dried as usual. It dyes cotton from a neutral or alkaline dye bath purple.
