Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 143026.    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-(Benzoylainino)-8-oxynaphthalin-4-sulfo-          säure    mit chromabgebenden Mitteln behandelt.  



  Der erhaltene metallhaltige Farbstoff bil  det getrocknet ein dunkles Pulver, das sich  in Wasser mit graublauer Farbe löst und  Naturseide in     rotstichig    grauen Tönen färbt.       Beispiel:     5,08 Teile des durch Kombinieren von       diazotiertem        5-Nitro-2-amino-l-pheiiol    und     1-          (Benzoylamino)-8-oxynaphthalin    - 4 -     sulfosäure     in alkalischer Lösung erhaltenen     Farbstoffes     werden in 400 Teilen Wasser gelöst und mit  20 Teilen einer 7,

  6      /o        Cr2        0s    enthaltenden       Fluorchromlösung    24-30 Stunden am Rück-         flusskühler    zum Kochen erhitzt.     Hierauf    wird  die gebildete Chromverbindung mit Kochsalz  abgeschieden, filtriert und bei mässiger Tem  peratur getrocknet.



      Additional patent to main patent no. 143026. 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- (benzoylainino) -8-oxynaphthalene-4-sulfonic acid is treated with chromium donating agents.



  The metal-containing dye obtained forms a dark powder when dried, which dissolves in water with a gray-blue color and dyes natural silk in reddish gray tones. Example: 5.08 parts of the dye obtained by combining diazotized 5-nitro-2-amino-1-phenol and 1- (benzoylamino) -8-oxynaphthalene-4-sulfonic acid in an alkaline solution are dissolved in 400 parts of water and mixed with 20 Split a 7,

  6 / o Cr2 0s containing fluorochrome solution heated to boiling for 24-30 hours on the reflux condenser. The chromium compound formed is then deposited with common salt, 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-2-diazo-l-phenol und 1-(Benzoylamirio)- 8-oxynaphthalin-4-sulfosäure mit chromabge benden Mitteln behandelt. Der erhaltene metallhaltige Farbstoff bil det getrocknet ein dunkles Pulver, das sich in Wasser mit graublauer Farbe löst und Naturseide in rotstichig grauen Tönen färbt. PATENT CLAIM: Process for the production of a new metal-containing dye, characterized in that the azo dye from 5- nitro-2-diazo-1-phenol and 1- (benzoylamirio) - 8-oxynaphthalene-4-sulfonic acid is treated with chromium-releasing agents. The metal-containing dye obtained forms a dark powder when dried, which dissolves in water with a gray-blue color and dyes natural silk in reddish gray tones.
