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-4-chlor-2-diazo-          1-phenol    und     1-Amino-8-oxynaphtbalin-4-sulfo-          säure    mit chromabgebenden Mitteln behandelt.  



  Der erhaltene metallhaltige Farbstoff bil  det getrocknet ein dunkles Pulver, das Natur  seide in grünen Tönen färbt.  



  <I>Beispiel:</I>  8,77 Teile des durch Kuppeln in alkali  scher Lösung erhaltenen Farbstoffes aus     dia-          zotiertem        5-Nitro-4-chlor-2-amino-1-phenol    und       1-Amirio-8-oxynaphthalin-4-sulfosäure    werden  in 600 Teilen Wasser gelöst und .mit 3,04  Teilen     Cr20a    in Form von     Fluorchrom    24       Stunden    am     Rückfluss    zum Kochen erhitzt.    Die gebildete Chromverbindung wird hierauf  durch Zugabe von Kochsalz abgeschieden, fil  triert und bei mässiger Temperatur 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-4-chloro-2-diazo-1-phenol and 1-amino-8-oxynaphthalene-4-sulfonic acid is treated with chromium donating agents .



  The metal-containing dye obtained forms a dark powder when dried, which dyes natural silk in green tones.



  <I> Example: </I> 8.77 parts of the dye obtained by coupling in an alkaline solution from diazotized 5-nitro-4-chloro-2-amino-1-phenol and 1-amirio-8-oxynaphthalene 4-sulfonic acid are dissolved in 600 parts of water and heated with 3.04 parts of Cr20a in the form of fluorochrome to reflux for 24 hours. The chromium compound formed is then deposited by adding sodium chloride, filtered and dried at a moderate temperature.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes, dadurch gekenn zeichnet, dass man den Azofarbstoff aus 5- Nitro-4-chlor-2-diazo-l-phenol und 1-Amino- 8-oxynaphthalin-4-sulfosäure mit chromabge benden Mitteln behandelt. Der erhaltene metallhaltige Farbstoff bil det getrocknet ein dunkles Pulver, das Natur seide in grünen Tönen färbt. PATENT CLAIM: Process for the production of a new metal-containing dye, characterized in that the azo dye from 5- nitro-4-chloro-2-diazo-1-phenol and 1-amino-8-oxynaphthalene-4-sulfonic acid with chromium-releasing agents treated. The metal-containing dye obtained forms a dark powder when dried, which dyes natural silk in green tones.
