  Verfahren zur Darstellung von Monoazofarbstoffen auf der vegetabilischen Faser. 



   In der Patentschrift Nr. 56761 sind Monoazofarbstoffe beschrieben, welche dadurch entstehen, dass man solche Diazoverbindungen der Benzolreihe, welche mindestens eine von der Sulfogruppe verschiedene negative Gruppe enthalten, mit den Arylamiden der 2. 3-Oxy-   naphtoesäure   kombiniert. 



   Es wurde nun gefunden, dass man die genannten Farbstoffe auch auf der vegetabilischen Faser erzeugen kann, nach den bei der Darstellung von Eisfarben üblichen Arbeitsweisen. 



  Man erhält so vollständig seifenechte, sehr lebhafte Töne, welche sich Tor den mit ss-Naphtol erzeugten, durch grössere Lichtechtheit auszeichnen. 



   Beispiel. 



   Der Stoff wird geklotzt mit einer Lösung von 25   9   2. 3-Oxynaphtoesäureanilid, 27 cm3 Natronlauge 34  Bé, 100 g rizinusölsaurem Natron, 20 g essigsaurem Natron, 40   cm3   Antimonlösung, auf 1 l gestellt.   (Diese Antimonlösung   wurde bereitet durch Verkochen von 80   9     Brechweinstein mit 200 Glyzerin, 100 g Natronlauge 34  Bé. Man stellt auf 1 l ein. ) Dann   wird gut getrocknet und mit einer   Diazotösung   entwickelt, die wie folgt dargestellt ist : 
 EMI1.1 
 und 200 cm3 kochendem Wasser gelost, gut abgekühlt und mit 150 g Eis versetzt.

   Man lässt hierauf in dünnem Strahle unter beständigem Rühren   15'6 9   Natriumnitrit, gelöst in 50   cm3 Wasser, einfliessen und   stellt auf   Il ein.   
 EMI1.2 
 saurem Natron 1 : 1. 



   Man erhält so auf der Faser ein leuchtendes Scharlachrot. 



   Auf gleiche Weise kann man die anderen Farbstoffe darstellen. So erhält man zum Beispiel mit Chloranisidin (O CH3.NH2:Cl=1 : 2 : 4) ein bläuliches Rot. 



   Klotzt man den Stoff aut entsprechende Weise mit einer Lösung von 2. 3-Oxynaphtoesaure-m-nitranilid und entwickelt mit der Diazoverbindung aus Nitroanisidin 
 EMI1.3 
 Färbung ein blaustichiges Rosa.

  Process for the representation of monoazo dyes on vegetable fibers.



   Patent specification No. 56761 describes monoazo dyes which are formed by combining diazo compounds of the benzene series which contain at least one negative group other than the sulfo group with the arylamides of 2,3-oxynaphthoic acid.



   It has now been found that the dyes mentioned can also be produced on the vegetable fiber using the usual procedures for the production of ice colors.



  In this way, completely soap-resistant, very lively tones are obtained, which are distinguished by greater lightfastness than those produced with ss-naphtol.



   Example.



   The fabric is padded with a solution of 25.92.3-oxynaphthoic anilide, 27 cm3 sodium hydroxide solution 34 Be, 100 g castor oil acid, 20 g acetic acid sodium, 40 cm3 antimony solution, to 1 l. (This antimony solution was prepared by boiling 80 9 tartar emetic with 200 glycerine, 100 g caustic soda 34 Bé. Adjust to 1 l.) It is then dried well and developed with a diazo solution, which is shown as follows:
 EMI1.1
 and 200 cm3 of boiling water, cooled well and mixed with 150 g of ice.

   15.6 9 sodium nitrite, dissolved in 50 cm3 of water, is then allowed to flow in in a thin stream with constant stirring and adjusted to II.
 EMI1.2
 Sour soda 1: 1.



   A bright scarlet red is obtained on the fiber.



   The other dyes can be represented in the same way. For example, with chloroanisidine (O CH3.NH2: Cl = 1: 2: 4) you get a bluish red.



   The substance is padded in a corresponding manner with a solution of 2. 3-oxynaphthoic acid-m-nitranilide and developed from nitroanisidine with the diazo compound
 EMI1.3
 Coloring a bluish pink.
