Description

  

  Verfahren zur Herstellung eines     metallhaltigen        Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den Farbstoff aus     diazotiertem        5-Nitro-2-          amino-l-phenol    und     ss-Naphtlrol    mit einem  eisen-,     aluminium-    und kupferhaltigen Pro  dukt, das durch Einwirkung einer     hydroxyl-          gruppenhaltigen    organischen Verbindung  auf Eisen-, Aluminium- und Kupferverbin  dungen in Gegenwart von Alkalien erhalten  wird, behandelt.  



  Der neue metallhaltige     Farbstoff    ist in  Wasser sehr schwer, in Natronlauge etwas  mit braunroter Farbe löslich. In konzentrier  ter Schwefelsäure löst er sich violett, und  aus der ebenfalls violetten Lösung in     Zapon-          lack    erhält man auf Metallfolien violette  Anstriche von sehr guter Lichtechtheit.  



  <I>Beispiel:</I>  6,18 Gewichtsteile des Farbstoffes aus  dianotiertem     5-Nitro-2-amino-l-phenol    und l  Naphthol werden in 500 Teilen Wasser und  <B>10</B> Teilen Natronlauge von<B>36'</B>     Be    gelöst    und mit einer     glyzerinhaltigon,    alkalischen  Lösung aus 0,65 Teilen Eisenchlorid, 0,69  Teilen Aluminiumsulfat und 3,0 Teilen kri  stallisiertem Kupfersulfat in 50 Teilen Was  ser, 5 Teilen Glyzerin und 20 Teilen Natron  lauge (36       B6)    kurze Zeit am     Rückfluss    zum  Kochen erhitzt. Nach dem Erkalten des  Reaktionsgemisches wird mit Essigsäure  neutralisiert und der abgeschiedene Farbstoff  filtriert, ausgewaschen und bei mässiger Tem  peratur getrocknet.  



  Ein gleiches Produkt wird erhalten, wenn  statt Glyzerin andere     hydroxylgruppenhaltige     organische Verbindungen, wie     Glykol,        Tannin,          Gallussäure,    Zuckerarten, Kohlenhydrate, ver  wendet werden.



  Process for the production of a metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye is made from diazotized 5-nitro-2-amino-1-phenol and ss-naphtholrol with an iron, aluminum and copper-containing product that is produced by the action of a hydroxyl - Group-containing organic compound on iron, aluminum and copper compounds in the presence of alkalis is obtained treated.



  The new metal-containing dye is very difficult in water and somewhat soluble in caustic soda with a brownish-red color. It dissolves violet in concentrated sulfuric acid, and the violet solution in Zapon varnish gives violet coatings of very good lightfastness on metal foils.



  <I> Example: </I> 6.18 parts by weight of the dye from dianotized 5-nitro-2-amino-1-phenol and 1 naphthol are mixed with 500 parts of water and 10 parts of sodium hydroxide solution > 36 '</B> Be dissolved and with a glycerin-containing, alkaline solution of 0.65 parts of ferric chloride, 0.69 parts of aluminum sulfate and 3.0 parts of kri-crystallized copper sulfate in 50 parts of water, 5 parts of glycerin and 20 parts of sodium hydroxide (36 B6) heated to reflux for a short time. After the reaction mixture has cooled, it is neutralized with acetic acid and the deposited dye is filtered, washed and dried at a moderate temperature.



  The same product is obtained if, instead of glycerine, other organic compounds containing hydroxyl groups, such as glycol, tannin, gallic acid, types of sugar, carbohydrates, are used.
