Description

  

  Zusatzpatent zum Hauptpatent Nr. 143026.    Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffe    Es wurde gefunden, dass man einen neuen  metallhaltigen     Farbstoff    erhält, wenn man  den     Azofarbstoff    aus     5-Nitro-2-diazo-l-phenol     und     1-(Acetylamino)-8-oxynaphthalin-4-sulfo-          säure    mit kupferabgebenden Mitteln behandelt.  



  Der erhaltene metallhaltige Farbstoff     bil-'          det    getrocknet ein dunkles Pulver, das Na  turseide in     rötlichblauen    Tönen färbt:    <I>Beispiel:</I>  4,46 Teile des     Farbstoffes,    welcher durch  Kuppeln von     diazotiertem        5-I@Titro-2-amino-          1-phenol    mit     1-(Acetylamino)-8-oxynaphtha-          lin-4-sulfosäui@e    in alkalischer Lösung erhal  ten wird, löst man in 400 Teilen Wasser,  kocht auf und versetzt mit 2,5 Teilen kri-         stallisiertein        Kupfersulfat    und 1,4 Teilen  kristallisierten:

       Natriumacetat,    kocht kurze  Zeit, salzt aus, filtriert und trocknet.



  Additional patent to main patent No. 143026. Process for the preparation of a new metal-containing dye It has been found that a new metal-containing dye is obtained if the azo dye is obtained from 5-nitro-2-diazo-1-phenol and 1- (acetylamino) -8 -oxynaphthalene-4-sulfonic acid treated with copper releasing agents.



  The metal-containing dye obtained forms a dark powder when dried, which dyes natural silk in reddish-blue tones: <I> Example: </I> 4.46 parts of the dye, which is obtained by coupling diazotized 5-I @ Titro-2- Amino-1-phenol with 1- (acetylamino) -8-oxynaphthalin-4-sulfosäui @ e is obtained in alkaline solution, it is dissolved in 400 parts of water, boiled and treated with 2.5 parts of crystallized copper sulfate and 1.4 parts crystallized:

       Sodium acetate, boil for a short time, salt out, filter and dry.
