Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr.<B>1272.60.</B>    Verfahren zur Herstellung eines neuen     Azofarbstofes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man das     3-ivletliy        1-          5-pyrazolon    mit der     Diazoverbindung    des       Farbstoffes    der Formel  
EMI0001.0008     
    kuppelt. Der neue Farbstoff stellt ein schwar  zes Pulver dar, welches sich mit blauvioletter  Farbe in verschiedenen organischen Lösungs  mitteln löst. Er ist zum Färben von Lacken  sehr gut geeignet und färbt diese.     Erzeugnisse     in violetten Tönen von vorzüglicher Licht  echtheit.  



  <I>Beispiel.:</I>  Eine wie üblich hergestellte     Dlazolösung     des     Farbstoffes    der Formel  
EMI0001.0012     
    wird in eine mit 30 Teilen kristallisiertem       Natriumacetat    versetzte Lösung von 10 Teilen       3-Methyl-5-pyi#azolord    eingegossen. Der sofort  ausfallende Farbstoff wird alsdann filtriert  und gegebenenfalls getrocknet.



  <B> Additional patent </B> to main patent no. <B> 1272.60. </B> Process for the production of a new azo dye. It has been found that a new azo dye is obtained if the 3-ivletliy 1- 5-pyrazolone is mixed with the diazo compound of the dye of the formula
EMI0001.0008
    clutch. The new dye is a black powder that dissolves in various organic solvents with a blue-violet color. It is very suitable for coloring paints and colors them. Products in purple tones with excellent lightfastness.



  <I> Example .: </I> A dlazo solution of the dye of the formula prepared as usual
EMI0001.0012
    is poured into a mixed with 30 parts of crystallized sodium acetate solution of 10 parts of 3-methyl-5-pyi # azolord. The dye which precipitates out immediately is then filtered and, if necessary, dried.
