Description

  

  Verfahren zur Herstellung eines metallhaltigen     Farbstoffes.       Es wurde     gefunden,    dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den Farbstoff aus     diazotiertem        5-Nitro-2-          amino-l-phenol    und     2,4-Dioxychinolin    in  einem Medium, dessen     PI,    nicht grösser als  10 ist, mit einem     kobaltabgebenden        Mittel     behandelt.  



  Der erhaltene Farbstoff stellt ein dunkel  rotbraunes Pulver dar, das sich in verdünn  ter     Sodalösung    mit gelbroter und in konzen  trierter Schwefelsäure     mit    oranger Farbe  löst. Aus der Lösung des Farbstoffes in       Zaponlack    erhält man auf Metallfolien  hirschrote Überzüge.  



  <I>Beispiel:</I>  3,26 Gewichtsteile des Farbstoffes aus     di-          a.zotiertem        5-Nitro-@2-amino-l-phenol    und     2,4-          Dioxychinolin    werden in 2000 Teilen Wasser  gelöst und mit 1,5 Teilen ameisensaurem Ko  balt 2 Stunden am     Rückflusskühler    zum  Kochen erhitzt. Hierauf wird die abgeschie  dene     Kobaltverbindung    des Farbstoffes fil-         triert,    ausgewaschen und bei mässiger Tem  peratur getrocknet.  



  Die Behandlung mit     Kobaltformiat    führt  zum gleichen Resultat, wenn man dem Reak  tionsgemisch Zusätze wie zum Beispiel     Na-          triumformiat,        Natriumacetat,    Kochsalz oder       Natriumsulfit    beigibt.



  Process for the production of a metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye of diazotized 5-nitro-2-amino-1-phenol and 2,4-dioxyquinoline in a medium whose PI is not greater than 10, with a treated cobalt-releasing agents.



  The dye obtained is a dark red-brown powder, which dissolves in dilute soda solution with yellow-red and in concentrated sulfuric acid with an orange color. Deer-red coatings are obtained on metal foils from the solution of the dye in zapon varnish.



  <I> Example: </I> 3.26 parts by weight of the dye from di- a.zotierter 5-nitro- @ 2-amino-1-phenol and 2,4-dioxyquinoline are dissolved in 2000 parts of water and 1.5 Share formic acid Ko balt heated to the boil for 2 hours on the reflux condenser. The deposited cobalt compound of the dye is then filtered, washed out and dried at a moderate temperature.



  Treatment with cobalt formate leads to the same result if additives such as sodium formate, sodium acetate, common salt or sodium sulfite are added to the reaction mixture.
