Description
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.
