Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 141535.    Verfahren zur Herstellung eines metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen     Farbstoff    erhält, wenn man  den Farbstoff     aus        diazotiertem        4-Nitro-2-          amitto-l-phenol    und     Resorcin    mit der Sus  pension einer Verbindung des dreiwertigen  Kobalts behandelt.  



  Der gebildete     Farbstoff    stellt ein dunkel  braunes Pulver dar, das sich in Wasser mit  kirschroter, in Natronlauge mit braunroter  und in konzentrierter Schwefelsäure mit  braungelber Farbe löst. Aus einer Lösung  in     Zaponlack    erhält man auf Metallfolien  lichtechte scharlachrote Überzüge.  



  <I>Beispiel:</I>  5,48 Teile des     Farbstoffes    aus     diazotiertem          4-Nitro-2-amino-l-phenol    und     Resorcin    werden  in 400 Teilen Wasser aufgekocht und mit  5,4 Teilen     Kobaltioxyd        (Co20s)    während  24 Stunden zum Sieden erhitzt. Nach dem  Erkalten wird der ausgeschiedene     Farbstoff          abfiltriert,    gewaschen und getrocknet. Durch         (Tmlösen    aus Soda wird die gebildete Kobalt  verbindung von überschüssigem Metalloxyd  getrennt und bei mässiger Temperatur ge  trocknet.



  <B> Additional patent </B> to main patent no. 141535. Process for the production of a metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye consisting of diazotized 4-nitro-2-amitto-1-phenol and resorcinol is treated with the suspension of a compound of trivalent cobalt.



  The dye formed is a dark brown powder that dissolves in water with a cherry-red color, in sodium hydroxide solution with a brown-red color and in concentrated sulfuric acid with a brown-yellow color. From a solution in zapon lacquer, lightfast scarlet coatings are obtained on metal foils.



  <I> Example: </I> 5.48 parts of the dye from diazotized 4-nitro-2-amino-l-phenol and resorcinol are boiled in 400 parts of water and mixed with 5.4 parts of cobalt dioxide (Co20s) for 24 hours Boiling heated. After cooling, the precipitated dye is filtered off, washed and dried. The cobalt compound formed is separated from the excess metal oxide by dissolving it from soda and dried at a moderate temperature.
