  Zusatzpatent zum Hauptpatent     Nr.   <B>185961.</B>    Verfahren zur Herstellung eines wasserlöslichen, komplex gebundenes Kupfer  enthaltenden     Farbstoffpräparates.       Es wurde gefunden,     dass    ein     wasserlös-        tendes        Farbstoffpräparat    erhalten werden       liches,    komplex gebundenes Kupfer     enthal-    kann, wenn man den     Azofarbstoff    der Formel  
EMI0001.0010     
    ein kupferabgebendes Mittel sowie     Amino-          essigsäure    oder ein Salz derselben aufeinander  einwirken     lässt.     



  Das so erhaltene wasserlösliche, komplex  gebundenes Kupfer enthaltende     Parbstoff-          präparat    stellt ein gelbes Pulver dar, das in  Wasser löslich ist; demgegenüber ist die  komplexe Kupferverbindung, die aus dem  selben     Azofarbstoff    durch Behandeln mit  einem kupferabgebenden Mittel in Abwesen  heit von     Aminoessigsäure    hergestellt wird,  in Wasser unlöslich.

   Das     Farbstoffpräparat     eignet sich insbesondere zum Färben von       zellulosehaltigem    Material, wie zum Beispiel  Baumwolle, Kunstseide aus regenerierter Zel-         lulose,    Papier,     Kokosfaser    und Jute; beim  Färben wird aus dem     Farbstoffpräparat          .Aminoessigsäure    abgespalten, und es werden  sehr echte, insbesondere. wasch- und licht  echte gelbe Färbungen, erhalten.  



  Das Verfahren kann beispielsweise derart  durchgeführt werden,     dass    man zuerst den       Azofarbstoff    obiger Formel mit dem kupfer  abgebenden Mittel reagieren     lässt        und    dann  auf die gebildete Kupferverbindung     amino-          essigsaures    Natron einwirken     lässt.       <I>Beispiel:

  </I>    <B>6,5</B> Teile des     Azofarbstoffes    der Formel    
EMI0002.0001     
    in Form seines     Natronsalzes,    werden in  200 Teilen Wasser bei<B>800</B>     C    gelöst und  mit einer wässerigen Lösung von<B>6</B> Teilen       aminoessigsaurdm    Kupfer versetzt, die er  halten wird durch kurzes Kochen einer Lö  sung von<B>1,6</B> Teilen     Aminoessigsäure    in<B>100</B>  Teilen Wasser mit einer solchen Menge  Kupferkarbonat, die     1,55    Teilen Kupfer ent  spricht. Man rührt einige Zeit, versetzt mit    Kochsalz, filtriert und trocknet gegebenen  falls.



  Additional patent to main patent no. <B> 185961. </B> Process for the production of a water-soluble, complex-bonded copper-containing dye preparation. It has been found that a water-dissolving dye preparation can contain complex-bonded copper if the azo dye of the formula
EMI0001.0010
    a copper-releasing agent and aminoacetic acid or a salt thereof can act on one another.



  The water-soluble, complex-bound copper-containing perfume preparation obtained in this way is a yellow powder which is soluble in water; In contrast, the complex copper compound, which is produced from the same azo dye by treatment with a copper donor in the absence of aminoacetic acid, is insoluble in water.

   The dye preparation is particularly suitable for dyeing cellulose-containing material, such as cotton, rayon made from regenerated cellulose, paper, coconut fiber and jute; When dyeing, aminoacetic acid is split off from the dye preparation, and it becomes very real, in particular. Washable and light-fast yellow colorations are preserved.



  The process can, for example, be carried out in such a way that the azo dye of the above formula is first allowed to react with the copper-releasing agent and then sodium aminacetate is allowed to act on the copper compound formed. <I> example:

  </I> <B> 6.5 </B> parts of the azo dye of the formula
EMI0002.0001
    in the form of its sodium salt, are dissolved in 200 parts of water at <B> 800 </B> C and mixed with an aqueous solution of <B> 6 </B> parts of aminoacetic acid copper, which is obtained by briefly boiling a solution of <B> 1.6 </B> parts of aminoacetic acid in <B> 100 </B> parts of water with an amount of copper carbonate equivalent to 1.55 parts of copper. The mixture is stirred for some time, mixed with common salt, filtered and dried, if necessary.
