Description

  

  Verfahren zur Herstellung eines metallhaltigen     Farbstoffes.       Es wurde gefunden,     dass    man einen  neuen metallhaltigen Farbstoff erhält, wenn  man den Farbstoff aus     diazotiertem        4-Nitro-          2-amino-l-phenol    und     Resorcin    mit     einem     metallhaltigen Produkt, das durch Einwir  kung von     hydroxylgruppenhaltigen    orga  nischen Verbindungen auf Eisen-, Alu  minium- und Kupfersalze in Gegenwart von  Alkalien erhalten wird, behandelt.  



  Die entstandene Metallverbindung stellt  getrocknet ein dunkelbraunes Pulver dar, das  sich in Wasser schwer mit brauner, in Na  tronlauge mit gelbbrauner und in konzen  trierter Schwefelsäure mit     braunstichig    gel  ber Farbe löst. In organischen Lösungsmit  teln ist. es leicht löslich und ergibt aus einer  Lösung in handelsüblichem     Zaponlack    auf  Aluminiumfolie braune, kräftige Überzüge  von sehr guter Lichtechtheit.

      <I>Beispiel:</I>  5,48 Teile des Farbstoffes aus     diazotier-          tem        4-Nitro-2-amino-l-phenol    und     Resorcin       werden in 400 Teilen Wasser und 10 Teilen  Natronlauge von 36       B6    gelöst und kochend  mit einer Glycerin und überschüssige Na  tronlauge enthaltenden Lösung von 1 Teil       Ferrichlorid,    1,9 Teilen Aluminiumsulfat und  1 Teil kristallisiertem Kupfersulfat in 50  Teilen Wasser versetzt. Nach dreistündigem  Kochen wird kalt gerührt, hierauf mit Essig  säure schwach sauer gestellt, filtriert, mit  Wasser neutral gewaschen und der Rück  stand bei 50-60   getrocknet.  



  Ein gleiches Endprodukt wird erhalten,  wenn statt Glycerin andere     hydroxylgrup-          penhaltige    organische Verbindungen, wie  Glykol,     Tannin,        Gallussäure,    Zuckerarten,  Kohlenhydrate, verwendet 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 4-nitro-2-amino-1-phenol and resorcinol with a metal-containing product that is produced by the action of hydroxyl-containing organic compounds on iron, aluminum minium and copper salts is obtained in the presence of alkalis, treated.



  The resulting metal compound, when dried, is a dark brown powder that dissolves with difficulty in water with a brown color, in sodium hydroxide solution with a yellow-brown color and in concentrated sulfuric acid with a brownish yellow color. In organic solvents is. it is easily soluble and, from a solution in commercially available zapon varnish on aluminum foil, results in strong, brown coatings of very good lightfastness.

      <I> Example: </I> 5.48 parts of the dye from diazotized 4-nitro-2-amino-1-phenol and resorcinol are dissolved in 400 parts of water and 10 parts of sodium hydroxide solution of 36 B6 and boiled with a glycerine and excess sodium hydroxide solution containing 1 part of ferric chloride, 1.9 parts of aluminum sulfate and 1 part of crystallized copper sulfate in 50 parts of water. After three hours of boiling, the mixture is stirred cold, then made slightly acidic with acetic acid, filtered, washed neutral with water and the residue was dried at 50-60.



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