Description

  

      Verfahren    zur Herstellung eines neuen     metallhaltigen    Farbstoffes.    Es wurde gefunden, dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  das Kupplungsprodukt aus     diazotierter    2  Amino-l-oxynaphthalin-3,8-disulfosäure und       ss-Resorcylsäure    mit Kupfersulfat behan  delt. Der neue metallhaltige Farbstoff bildet  ein dunkles Pulver, löst sich in Wasser mit  blauroter Farbe und erzeugt auf Wolle, aus  saurem Bade gefärbt, echte rotviolette Töne.

    <I>Beispiel:</I>  48,7 Teile des Farbstoffes aus der     Di-          azoverbindung    der     2-Amino-l-oxy        naphthalin-          3,8-disulfosäure    und     ss-Resorcylsäure    werden  in 2000 Teilen Wasser kochend gelöst. Hier  auf setzt man dieser Lösung 21 Teile Kup  fersulfat, gelöst in 300 Teilen heissem Was  ser, zu und kocht das Gemisch noch einige  Zeit weiter, indem die frei gewordene Mine-         ralsäure    mit     Natriumacetat    abgestumpft  wird. Der kupferhaltige Farbstoff wird  hernach durch Zusatz von Kochsalz gewon  nen.



      Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the coupling product of diazotized 2-amino-1-oxynaphthalene-3,8-disulfonic acid and β-resorcylic acid is treated with copper sulfate. The new metal-containing dye forms a dark powder, dissolves in water with a blue-red color and produces real red-violet tones on wool dyed from an acid bath.

    <I> Example: </I> 48.7 parts of the dye from the diazo compound of 2-amino-1-oxy naphthalene-3,8-disulfonic acid and ß-resorcylic acid are dissolved in 2000 parts of boiling water. On top of this, 21 parts of copper sulphate, dissolved in 300 parts of hot water, are added to this solution and the mixture is boiled for some time, blunting the released mineral acid with sodium acetate. The copper-containing dye is then won by adding table salt.
