Description

  

      Zusatzpatent    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-Chlor-          z-amino-l-phenol    und     Resorcin    in einem  Medium, dessen     Pii    nicht grösser als 10  ist, mit einem nickelabgebenden Mittel  behandelt.  



  Der erhaltene Farbstoff stellt ein gelb  braunes Pulver dar, das sich in Natron  lauge mit tiefroter und in     konz.    Schwefel  säure mit braungelber Farbe löst. Aus der  orange gefärbten Lösung des Farbstoffes in       Zaponlack    erhält man auf Metallfolien  orange gefärbte Anstriche.  



  <I>Beispiel:</I>  2,63 Gewichtsteile des Farbstoffes aus       diazotiertem        4-Chlor--2-amino-l-phenol    und       Resorcin    werden in 25,0 Teilen Wasser mit  einer 0,64 Teilen Nickel entsprechenden  Menge Nickelsulfat unter Zusatz der äqui  valenten Menge     Natriumformiat    einige Zeit    am     Rückfluss    zum Kochen erhitzt, nach dem  Erkalten der ausgeschiedene Farbstoff ab  filtriert, gewaschen und bei mässiger Tem  peratur getrocknet.  



  Die Behandlung mit Nickelsulfat führt  zum gleichen Resultat, wenn man das im  Beispiel verwendete     Natriumformiat    zum  Beispiel durch     Natriumacetat,    Kochsalz oder       Natriumsulfit    ersetzt.



      Additional patent 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 made from diazotized 4-chloro-z-amino-1-phenol and resorcinol is treated with a nickel-releasing agent in a medium whose Pii is not greater than 10.



  The dye obtained is a yellow-brown powder, which is in sodium hydroxide solution with deep red and in conc. Sulfuric acid dissolves with a brownish yellow color. Orange-colored paints are obtained on metal foils from the orange-colored solution of the dye in zapon varnish.



  <I> Example: </I> 2.63 parts by weight of the dye from diazotized 4-chloro-2-amino-1-phenol and resorcinol are added to 25.0 parts of water with an amount of nickel sulfate corresponding to 0.64 part of nickel the equivalent amount of sodium formate heated to the boil under reflux for some time, after cooling the precipitated dye is filtered off, washed and dried at a moderate temperature.



  Treatment with nickel sulphate leads to the same result if the sodium formate used in the example is replaced, for example, by sodium acetate, common salt or sodium sulphite.
