Description

  

  Zusatzpatent zum Hauptpatent     Nr.    143026.    Verfahren zur     Rerstellung    eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden,     dass    man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den     Azolarbstoff    aus     5-Niti-o-2-diazo-l-pheiiol     und     1-Aniino-8-oxynaphtbalit)-4-sulfosätire    mit       ehromabgebenden    Mitteln behandelt.  



  Der erhaltene metallhaltige Farbstoff bil  det getrocknet ein dunkles Pulver, das sich  in Wasser mit blaustichig grüner Farbe löst  und Wolle sowie Seide in grünen Tönen  färbt.  



  <I>Beispiel:</I>  <B>8,08</B> Teile des Farbstoffes aus     diazotiertem          5-Nitro-2-amiiio-l-phenol    und     1-Amirio-S-oxy-          naphthalin-4-sulfosäure,    in alkalischer Lösung  kombiniert, werden in<B>500</B> Teilen Wasser  gelöst und mit einer 3,04 Teilen     Or20s    ent  sprechenden Menge an     Fluorchrom        2-4-,#i0       Stunden am     Rückfluss    zum Kochen erhitzt.  Hierauf wird die gebildete     Chroinvet-b,iidtitig     mit Kochsalz abgeschieden,     filtriert    und bei  mässiger Temperatur 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 azoic material composed of 5-Niti-o-2-diazo-1-phenol and 1-Aniino-8-oxynaphthalite) -4-sulfosate is treated with an homomorbid agent.



  The metal-containing dye obtained forms a dark powder when dried, which dissolves in water with a bluish green color and dyes wool and silk in green tones.



  <I> Example: </I> <B> 8.08 </B> parts of the dye from diazotized 5-nitro-2-amiiio-1-phenol and 1-amirio-S-oxynaphthalene-4-sulfonic acid, combined in an alkaline solution, are dissolved in <B> 500 </B> parts of water and heated to boiling under reflux with a 3.04 parts of Or20s corresponding amount of fluorochrome for 2-4, # 10 hours. The chroinvet-b formed is then precipitated iidtitig with common salt, filtered and dried at moderate temperature.
