Description

  

      Verfahren    zur Herstellung von wasserunlöslichen     Azofarbstoffen       Gegenstand des Hauptpatentes ist ein Verfahren  zur Herstellung von wasserunlöslichen     Azofarbstof-          fen,    welches dadurch gekennzeichnet ist, dass man die       Diazoniumverbindungen    aus     o-Amino-azoverbindun-          gen    der Formel  
EMI0001.0008     
    worin X eine     Alkyl-    oder     Alkoxygruppe    bedeutet, mit       Arylamiden    der     2,3-Oxy-naphthoesäure,    die keine       wasserlöslichmachenden    Gruppen enthalten, kuppelt.

    



  Nach diesem Verfahren erhält man     Farbstoffe,     die auf pflanzlichen Fasern nach den bekannten  Färbe- und Druckverfahren     grünstichig    braune bis  grüne Färbungen und Drucke von guten Echtheits  eigenschaften ergeben, wie sie bisher     in    der Eisfarben  reihe unter Verwendung von     Diazokomponenten    noch  nicht erhalten werden konnten.  



  Die Farbstoffe können auch zum Färben von  hochmolekularen plastischen Massen oder für die  Zubereitung von Farblacken verwendet werden.  



  Bei der Weiterbearbeitung dieses Erfindungs  gedankens wurde nun gefunden, dass man zu wasser  unlöslichen     Azofarbstoffen    von ähnlich wertvollen  Eigenschaften gelangt, wenn man die     Diazoniumver-          bindungen    aus     o-Amino-azoverbindungen    der Formel  
EMI0001.0022     
    mit     Arylamiden    der     2,3-Oxy-naphthoesäure,    die keine       wasserlöslichmachenden    Gruppen enthalten, kuppelt.  



  Mit den neuen Farbstoffen kann man auf pflanz  lichen Fasern, einschliesslich solchen aus regenerierter       Cellulose,    nach den bekannten Färbe- und Druckver  fahren vorwiegend     grünstichig    braune bis grüne Fär  bungen und Drucke von guten Echtheitseigenschaften  erhalten.  



  Die Farbstoffe können auch zum Färben von  hochmolekularen plastischen Massen oder für die  Zubereitung von Farblacken verwendet werden.  



  Die Herstellung der als     Diazokomponenten    ver  wendeten     o-Amino-azoverbindüngen    kann nach be  kannten Methoden erfolgen.  



  <I>Beispiel</I>  47 g     2-Amino-4,5-diäthoxy-2'-phenylsulfonyl-4'-          nitro-1,1'-azobenzol    in Form des     Diazoniumsulfats     werden in 4 Liter Wasser gelöst. Zu dieser     Diazo-          lösung    lässt man unter gutem Rühren eine Lösung  von 30 g     1-(2',3'-Oxy-naphthoylamino)-2-methoxy-          benzol    in verdünnter Natronlauge zulaufen. Durch  allmähliches Erwärmen auf 900 C     wird    die Kupplung  beendet. Der gebildete     grünstichig    schwarze     Farbstoff     wird     abfiltriert,    gut ausgewaschen und getrocknet.  



  Man kann die Kupplung auch in     Gegenwart    eines  zur     Farblackherstellung    geeigneten Trägerstoffes vor  nehmen.  



  Die folgende Tabelle enthält noch eine Anzahl  von weiteren erfindungsgemäss verwendbaren Kom  ponenten sowie die Farbtöne der daraus erhältlichen       Azofarbstoffe,    die gute Echtheitseigenschaften be  sitzen.

      Process for the production of water-insoluble azo dyes The subject of the main patent is a process for the production of water-insoluble azo dyes, which is characterized in that the diazonium compounds are derived from o-amino-azo compounds of the formula
EMI0001.0008
    wherein X denotes an alkyl or alkoxy group, couples with arylamides of 2,3-oxynaphthoic acid which contain no water-solubilizing groups.

    



  This process gives dyes that produce greenish brown to green dyeings and prints of good fastness properties on vegetable fibers by the known dyeing and printing processes, as previously not been able to be obtained in the ice paint series using diazo components.



  The dyes can also be used for coloring high molecular weight plastic masses or for the preparation of colored lacquers.



  In further processing this idea of the invention, it has now been found that water-insoluble azo dyes with similar valuable properties are obtained if the diazonium compounds are obtained from o-amino-azo compounds of the formula
EMI0001.0022
    with aryl amides of 2,3-oxynaphthoic acid, which contain no water-solubilizing groups, couples.



  The new dyes can be used on vegetable fibers, including those made from regenerated cellulose, by the known dyeing and printing processes, predominantly greenish brown to green dyeings and prints with good fastness properties.



  The dyes can also be used for coloring high molecular weight plastic masses or for the preparation of colored lacquers.



  The o-amino-azo compounds used as diazo components can be prepared by known methods.



  <I> Example </I> 47 g of 2-amino-4,5-diethoxy-2'-phenylsulfonyl-4'-nitro-1,1'-azobenzene in the form of the diazonium sulfate are dissolved in 4 liters of water. A solution of 30 g of 1- (2 ', 3'-oxynaphthoylamino) -2-methoxybenzene in dilute sodium hydroxide solution is allowed to run into this diazo solution with thorough stirring. The coupling is terminated by gradually heating to 900 ° C. The greenish black dye formed is filtered off, washed well and dried.



  The coupling can also be carried out in the presence of a carrier suitable for the production of colored varnishes.



  The following table also contains a number of other components which can be used according to the invention and the hues of the azo dyes obtainable therefrom, which have good fastness properties.
