Description

  

      Zusatzpatent    zum Hauptpatent Nr. 312189    Verfahren zur     Herstellung    eines kupferhaltigen     Polyazofarbstoffes    der     Stilbenreihe       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines kupfer  haltigen     Polyazofarbstoffes    der     Stilbenreihe,       welches darin besteht,

   dass man 1     Mol    der       Aminotrisazoverbindung    der Zusammenset  zung  
EMI0001.0009     
         diazotiert    und den     Diazokörper    mit 1     Mol    der       Kupferkomplexverbindung    von     2,2',4'-Trioxy-          1,1'-azoben7ol-5-sulfonsäure    vereinigt.  



  Der neue, kupferhaltige     Polyazofarbstoff     ist ein braunschwarzes     Pulver,    welches sich in       Wasser    mit     violettstichig    brauner Farbe löst    und     Chromvelourleder    in dunkelbraunen,  schleifechten Tönen färbt.  



  Im nachfolgenden Beispiel bedeuten die  Teile     Gewichtsteile,    und die Prozente sind in  Gewichtsprozenten angegeben.    <I>Beispiel</I>  79,1 Teile der     Aminotrisazoverbindung    der Formel  
EMI0001.0023     
    werden     in    Form des     Natriumsalzes    in 1000  Teilen Wasser gelöst und durch Zugabe einer  Lösung von 7 Teilen     Natriumnitrit    in 20 Tei  len Wasser und 30 Teilen     30o/oiger    Salzsäure  bei 15      diazotiert.    Die     Diazosuspension    lässt  man zu einer     eisgekühlten    Lösung von 37,

  2    Teilen der     Kupferkomplexverbindung    von       2,2',4'-Trioxy-1,1'-azobenzol-5-sulfonsäure    und  40 Teilen     Natriumcarbonat    in 400 Teilen  Wasser fliessen. Nach beendigter Kupplung  wird der erhaltene     Polyazofarbstoff    durch  Zugabe von     Natriumchlorid    abgeschieden, von      der Lösung     abfiltriert    und     getroeknet.    Er ist  ein braunschwarzes Pulver, welches sich in  Wasser mit     violettstichig        brauner    Farbe löst    und     Chromvelourleder    in dunkelbraunen,  schleifechten Tönen färbt.



      Additional patent to main patent No. 312189 Process for the production of a copper-containing polyazo dye of the stilbene series The subject of the present patent is a process for the production of a copper-containing polyazo dye of the stilbene series, which consists in

   that one mole of the aminotrisazo compound of the composition
EMI0001.0009
         diazotized and the diazo body combined with 1 mole of the copper complex compound of 2,2 ', 4'-trioxy-1,1'-azoben7ol-5-sulfonic acid.



  The new, copper-containing polyazo dye is a brown-black powder that dissolves in water with a purple-tinged brown color and dyes chrome suede in dark brown, abrasion-resistant tones.



  In the following example, parts are parts by weight and percentages are percentages by weight. <I> Example </I> 79.1 parts of the aminotrisazo compound of the formula
EMI0001.0023
    are dissolved in 1000 parts of water in the form of the sodium salt and diazotized at 15 by adding a solution of 7 parts of sodium nitrite in 20 parts of water and 30 parts of 30% hydrochloric acid. The diazo suspension is added to an ice-cold solution of 37

  2 parts of the copper complex compound of 2,2 ', 4'-trioxy-1,1'-azobenzene-5-sulfonic acid and 40 parts of sodium carbonate in 400 parts of water flow. After the coupling is complete, the polyazo dye obtained is precipitated by adding sodium chloride, the solution is filtered off and dried. It is a brown-black powder that dissolves in water with a purple-tinged brown color and dyes chrome suede in dark brown, abrasion-resistant tones.
