Description

  

  Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den     Azofarbstoff    aus     5-Nitro-2-diazo-l-phenol     und     1-Amino-8-ogynaphthalin-4-sulfosäure    mit  nickelabgebenden Mitteln behandelt.  



  Der erhaltene metallhaltige     Farbstoff    bil  det getrocknet ein dunkles Pulver, das Natur  seide in grünblauen Tönen färbt.    <I>Beispiel:</I>    8,08 Teile des     Farbstoffes    aus     diazotier-          tern        5-Nitro-2-amino-l-phenol    und     1-Amino-          8-ogyriaphthalin-4-sulfosäure,    in alkalischer  Lösung kombiniert, werden in 500 Teilen  Wasser gelöst und mit 5,5 Teilen kristalli  siertem Nickelsulfat und 4 Teilen kristalli  siertem     Natriumacetat    kurze Zeit am Rück  flusskühler zum Kochen erhitzt. Hierauf wird    die gebildete Nickelverbindung des Farb  stoffes durch Kochsalz abgeschieden, filtriert  und getrocknet.



  Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the azo dye composed of 5-nitro-2-diazo-1-phenol and 1-amino-8-ogynaphthalene-4-sulfonic acid is treated with nickel-releasing agents.



  The metal-containing dye obtained forms a dark powder when dried, which dyes natural silk in green-blue tones. <I> Example: </I> 8.08 parts of the dye from diazotized 5-nitro-2-amino-1-phenol and 1-amino-8-ogyriaphthalene-4-sulfonic acid, combined in alkaline solution, are in 500 parts of water dissolved and heated to boiling for a short time on a reflux condenser with 5.5 parts of crystallized nickel sulfate and 4 parts of crystallized sodium acetate. The nickel compound formed in the dye is then deposited by sodium chloride, filtered and dried.
