Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>165155.</B>    'Verfahren zur Herstellung eines     inetallhaltigen    Farbstoffes.    <B>Es</B> wurde gefunden,     dass    man einen     ine-          tallhaltigen    Farbstoff durch Behandeln des       Azofarbstoffes    aus     diazotiertem        4-Chlor-2-          amino-I-phenol    und     1-Phenyl-3-methyl-5-          pyrazolon    mit     chrornabgebenden    Mitteln in  alkalischem Medium erhalten kann, wenn  diese Behandlung in Gegenwart von Salzen  der Weinsäure erfolgt.  



  Der erhaltene     ehromhaltige    Farbstoff stellt  ein rotes Pulver dar, das sich in organischen  Lösungsmitteln mit gelbroter Farbe löst und  aus einer Lösung in handelsüblichen     Nitro-          zelluloselacken    auf Metallfolien lichtechte,  scharlachrote Überzüge ergibt.

      <I>Beispiel:</I>  <B>6,51</B> Gewichtsteile des     Farbstoffes    aus       diazotiertem        4-Chloi--2-amitio-l-phenol    und       1-Phenyl-3-methyl-5-pyrazolon    werden in       400        Teilen        Wasser        und        2,7        Teilen        30%iger     Natronlauge aufgekocht und mit einer aus  <B>11,8</B> Teilen     Chromisulfat,   <B>9</B> Teilen Weinsäure,

         40        Teilen        Wasser        und        29,2        Teilen        30        %iger       Natronlauge erhaltenen komplexen Chrom  lösung versetzt. Nach     lOstündigem    Kochen  wird mit     Essigsätire    neutralisiert, der ausge  schiedene Farbstoff     abfiltriert,    gewaschen und  getrocknet.



  Additional patent to main patent no. <B> 165155. </B> 'Process for the production of a metal-containing dye. It has been found that an metal-containing dye can be obtained by treating the azo dye composed of diazotized 4-chloro-2-amino-1-phenol and 1-phenyl-3-methyl-5-pyrazolone with chromium-donating agents can be obtained in an alkaline medium if this treatment is carried out in the presence of salts of tartaric acid.



  The resulting Ehrom-containing dye is a red powder which dissolves in organic solvents with a yellow-red color and, from a solution in commercially available nitrocellulose lacquers on metal foils, results in lightfast, scarlet-red coatings.

      <I> Example: </I> <B> 6.51 </B> parts by weight of the dye from diazotized 4-chloro-2-amitio-1-phenol and 1-phenyl-3-methyl-5-pyrazolone are used in 400 parts of water and 2.7 parts of 30% sodium hydroxide solution are boiled and mixed with one of <B> 11.8 </B> parts of chromium sulfate, <B> 9 </B> parts of tartaric acid,

         40 parts of water and 29.2 parts of 30% sodium hydroxide solution obtained complex chromium solution were added. After boiling for 10 hours, it is neutralized with acetic acid, and the dye which has separated out is filtered off, washed and dried.
