Description

  

      Zusatzpatent    zum Hauptpatent Nr. 141635.    Verfahren zur Herstellung eines metallhaltigen Farbstoffes.    Es wurde gefunden, dass man einen  neuen metallhaltigen Farbstoff erhält, wenn  man den Farbstoff aus     diazotiertem        4-Chlor-          2-amino-l-phenol    und     ss-Naphthylamin    mit  einem eisen- und     kobalthaltigen    Produkt,

   das  durch     Einwirkung    einer     hydroxylgruppen-          haltigen    organischen     Verbindung    auf     Eisen-          und        Kobaltverbindungen    in Gegenwart von       Alkalien    erhalten wird, behandelt.  



  Der metallhaltige Farbstoff ist in Was  ser oder     Na..ronlauge    unlöslich. In konzen  trierter Schwefelsäure löst er sich mit     violet-          l    er, in organischen Lösungsmitteln mit  braunvioletter Farbe. Aus einer Lösung in       Zaponlack    erhält man auf geeigneten Unter  lagen je nach der Konzentration     braunstichig     violette bis schwarzviolette Überzüge.

      <I>Beispiel:</I>     ,l>     5,95 Teile des Farbstoffes aus     diazotier-          tem        4-Chlor-2-amino-l-phenol    und     ss-Naph-          thylamin    werden in 5,00 Teilen Wasser und  1.0 Teilen Natronlauge von 36       B6    aufge-    kocht und mit einer aus 2,6 Teilen Eisen  chlorid, 0,95 Teilen kristallisiertem     Kobalt-          chlorid,    50 Teilen Wasser, i Teilen     Glycerin     und 20 Teilen Natronlauge erhaltenen     11Ie-          tallhydroxydlösung    zwei Stunden am Rück  fluss im Sieden gehalten.

   Hierauf wird der  ausgeschiedene Farbstoff     abfiltriert,    ausge  waschen und getrocknet.  



  Ein gleiches Endprodukt wird erhalten,  wenn statt Glycerin andere     hydroxylgrup-          penhaltige    organische Verbindungen, wie  Glykol,     Tannin,        Gallussäure,    Zuckerarten,  Kohlenhydrate, verwendet werden.



      Additional patent to main patent no. 141635. 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 obtained from diazotized 4-chloro-2-amino-1-phenol and ß-naphthylamine with an iron and cobalt-containing product,

   which is obtained by the action of an organic compound containing hydroxyl groups on iron and cobalt compounds in the presence of alkalis.



  The metal-containing dye is insoluble in water or sodium hydroxide solution. In concentrated sulfuric acid it dissolves with violet color, in organic solvents with brownish-violet color. From a solution in Zapon lacquer, brownish violet to black violet coatings are obtained on suitable substrates, depending on the concentration.

      <I> Example: </I>, l> 5.95 parts of the dye from diazotized 4-chloro-2-amino-1-phenol and ß-naphthylamine are dissolved in 5.00 parts of water and 1.0 part of sodium hydroxide solution of 36 B6 are boiled up and boiled under reflux for two hours with a metal hydroxide solution obtained from 2.6 parts of iron chloride, 0.95 parts of crystallized cobalt chloride, 50 parts of water, 1 part of glycerol and 20 parts of sodium hydroxide solution.

   The precipitated dye is then filtered off, washed out and dried.



  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.
