Description

  

  Verfahren zur Herstellung eines neuen     indigolden        Farbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     indigoiden     Farbstoffes, dadurch gekennzeichnet, dass man  6.     7-Dimethyl-5-methoxy-3-oxythionaphthen     mit     2.1-Naphthoxy-thiophen-anil    kondensiert.  



  Das Produkt färbt die Faser aus gold  gelber     Küpe    oliv. Die Färbungen sind hervor  ragend lichtecht. Der     Farbstoff    ist auch für  den Zeugdruck geeignet.         Beispiel:       <I>a)</I>     Darstellung   <I>des</I>     Oxythioraapht%ens:    Die  Darstellung des     Oxythionaphthens    erfolgt in  der gleichen Weise wie in Absatz a) des  Beispiels des Hauptpatentes beschrieben.  



  <I>b)</I>     Herstellung   <I>des</I>     Z'arbslofes:    5 Teile     6.7-          Dimetbyl-5-methoxy#3-oxythionaphthen,   <B>6,6</B>  Teile     2.1-Naphthoxy-thiophen-anil,    120 Teile    Eisessig werden unter Rühren 5 Stunden lang  auf 115   erhitzt. Der ausgeschiedene Farb  stoff wird abgesaugt, getrocknet und aus  Schwefelsäure vergastet.



  Process for the production of a new indigolden dye. The present patent relates to a process for the production of an indigoid dye, characterized in that 6. 7-dimethyl-5-methoxy-3-oxythionaphthene is condensed with 2.1-naphthoxy-thiophene-anil.



  The product dyes the fibers from the golden yellow vat olive. The colors are extremely lightfast. The dye is also suitable for stuff printing. Example: <I> a) </I> Representation <I> des </I> Oxythioraapht% ens: The representation of oxythionaphthene takes place in the same way as described in paragraph a) of the example of the main patent.



  <I> b) </I> Preparation of <I> the </I> Z'arbslofes: 5 parts of 6.7-dimethyl-5-methoxy # 3-oxythionaphthene, <B> 6.6 </B> parts of 2.1-naphthoxy -thiophen-anil, 120 parts of glacial acetic acid are heated to 115 for 5 hours with stirring. The precipitated dye is suctioned off, dried and gasified from sulfuric acid.
