  Zusatzpatent zum Hauptpatent     Nr.   <B>166156.</B>    Verfahren zur Herstellung eines     inetallhaltigen        Farbstoffes.       Es wurde gefunden,     dass    man einen     nie-          tallhaltigen    Farbstoff durch Behandeln des       Azofarbstoffes    aus     diazotiertem    4<B>-</B> Chlor<B>-</B> 2  <B>- 1 -</B>     phenol    und 2<B>-</B>     Oxynaplithalin    mit  <B>z</B>     aiiiino     eisenabgebenden Mitteln in alkalischem Me  dium erhalten kann,

   wenn die Behandlung in       fi          i'Tegenwart    von Salzen der Weinsäure erfolgt.  Der erhaltene eisenhaltige Farbstoff stellt  ein dunkles Pulver dar, das sich in Alkohol  sehr leicht löst und aus einer Lösung in     Ni-          tro-    oder     Acetylzelltiloselack    auf geeigneten  Unterlagen braune bis braunschwarze     Über-          züge'ergibt.     



  <I>Beispiel:</I>  <B>30</B> Teile des Farbstoffes aus     diazotiertem          4-Chlor-2-arnino-l-phenol    und     2-Oxynaphtha-          lin    werden in 400 Teilen Wasser und<B>15</B>       Teilen        30%iger        Natronlauge        aufgeschlämmt     und bei 40<B>0</B> mit einer Lösung von<B>8,1</B> Teilen       Ferrichlorid,   <B>3,6</B> Teilen Weinsäure,<B>30</B> Teilen  Wasser und<B>36</B> Teilen<B>30</B>     '/oige    Natronlauge    versetzt.

   Man erwärmt einige Stunden auf  <B>80-90</B>     11,    neutralisiert mit     verdünnterAmeisen-          säure,        filtriert,    wäscht aus und trocknet bei  mässiger Temperatur.



  Additional patent to main patent no. <B> 166156. </B> Process for the production of a metal-containing dye. It has been found that a metal-containing dye can be obtained by treating the azo dye from diazotized 4 <B> - </B> chlorine <B> - </B> 2 <B> - 1 - </B> phenol and 2 < B> - </B> Oxynaplithalin can be obtained with <B> z </B> aiiiino iron-releasing agents in an alkaline medium,

   if the treatment is carried out in the presence of salts of tartaric acid. The iron-containing dye obtained is a dark powder which dissolves very easily in alcohol and, from a solution in nitro or acetyl cell silose lacquer on suitable substrates, gives brown to brown-black coatings.



  <I> Example: </I> <B> 30 </B> parts of the dye from diazotized 4-chloro-2-arnino-1-phenol and 2-oxynaphthalene are in 400 parts of water and <B> 15 < / B> parts of 30% sodium hydroxide solution slurried and at 40 <B> 0 </B> with a solution of <B> 8.1 </B> parts of ferric chloride, <B> 3.6 </B> parts of tartaric acid, <B> 30 </B> parts of water and <B> 36 </B> parts of <B> 30 </B>% sodium hydroxide solution are added.

   The mixture is heated to <B> 80-90 </B> 11 for a few hours, neutralized with dilute formic acid, filtered, washed out and dried at a moderate temperature.
