Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>165155.</B>    Verfahren zur Herstellung eines, metallhaltigen     Farbstoffes.       Es wurde gefunden,     dass    man einen me  tallhaltigen Farbstoff durch Behandeln des       Azofarbstoffes    aus     diazotiertem    4<B>-</B> Chlor<B>-</B>     2-          amiiio-1.-phenol    und 2.<B>3 -</B>     Oxynaphthoesäure-          anilicl    mit     kobalt-    und     ehromabgebenden     Mitteln in alkalischem Medium erhalten kann,  wenn diese Behandlung in Gegenwart von  Salzen der Weinsäure erfolgt.  



  Der erhaltene     kobalt-    und chromhaltige  Farbstoff stellt ein violettes Pulver dar, das  aus einer Lösung in     Nitro-    oder     Acetylzellu-          loselack    auf geeigneten Unterlagen violette  Überzüge gibt.  



  <I>Beispiel:</I>  42 Gewichtsteile des Farbstoffes aus     di-          azotiertem        4-Ohloi#-2-amirio-l-phenol    und  2<B>. 3 -</B>     Oxynaphthoesäureanilid    werden in 400       Teilen        Wasser        und        54        Teilen        30%iger        Na-          tronlauge    aufgeschlämmt und bei<B>65 "</B> mit  einer Lösung aus<B>16</B> Teilen kristallisiertem       Chromisulfat,   <B>5,6</B> Teilen kristallisiertem     Ko-          baltsulfat,

     <B>30</B> Teilen Weinsäure,<B>150</B> Teilen  Wasser und<B>110</B> Teilen<B>80</B>     Il'oiger    Natronlauge  versetzt. Hierauf erwärmt man     auf   <B>100 0</B> und    hält während<B>18</B> Stunden unter     Rückfluss    im  Sieden. Nach Beendigung der     Metallisierung     wird mit verdünnter Ameisensäure     neuträli-          siert,    der abgeschiedene Farbstoff     abfiltriert,          ausgewasehen        und    bei mässiger Temperatur  getrocknet.



  Additional patent to main patent no. <B> 165155. </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- amiiio-1.-phenol and 2. <B> 3 - </B> Oxynaphthoic acid anilicl with cobalt and Ehrom donating agents in an alkaline medium can be obtained if this treatment is carried out in the presence of salts of tartaric acid.



  The cobalt and chromium-containing dye obtained is a violet powder which, from a solution in nitro or acetyl cellulose lacquer, gives violet coatings on suitable substrates.



  <I> Example: </I> 42 parts by weight of the dye composed of diacotized 4-Ohloi # -2-amirio-1-phenol and 2 <B>. 3 - Oxynaphthoic anilide are suspended in 400 parts of water and 54 parts of 30% strength sodium hydroxide solution and at <B> 65 "</B> with a solution of <B> 16 </B> parts of crystallized chromium sulfate, < B> 5.6 parts of crystallized cobalt sulfate,

     <B> 30 </B> parts of tartaric acid, <B> 150 </B> parts of water and <B> 110 </B> parts of <B> 80 </B> sodium hydroxide solution are added. The mixture is then heated to <B> 100 0 </B> and refluxed for <B> 18 </B> hours. When the metallization is complete, the mixture is neutralized with dilute formic acid, and the deposited dye is filtered off, washed out and dried at a moderate temperature.
