  Verfahren zur Erzeugung echter Färbungen auf der pflanzlichen Faser. 



   In der deutschen Patentschrift Nr. 256999 und einer Reihe anderer sind Farbstoffe beschrieben, welche durch Kombination von   unsulfierten   Diazoverbindungen mit 2. 3-Oxynaphtoesäurearyliden entstehen und unter anderem zur Erzeugung von wertvollen Färbungen auf Faserstoffen dienen können. 



   Es wurde nun gefunden, dass man besonders wertvolle Färbungen erhält, wenn man die mit einer Lösung des 2. 3-Oxynaphtoesäure-ss-naphtalids imprägnierte Faser mit den Diazoverbindungen solcher Aminobasen behandelt, welche in 2. 5-Stellung zur Aminogruppe Substituenten tragen, von denen mindestens einer ein Chloratom ist. Als geeignete Basen kommen z. B. in Betracht: p-Chlor-o-toluidin 
 EMI1.1 
 CI = 1 : 2 : 5) usw. 



   Die so erhaltenen Farbstoffe zeichnen sich neben einer klaren Nuance und guten Echtheitseigenschaften besonders durch vorzügliche Bäuchechtheit aus. 



   Beispiel : Gut ausgekochtes und getrocknetes Garn wird mit einer Lösung von 
 EMI1.2 
 
8 cc Türkischrotöl im Liter imprägniert, gründlich abgewunden und, ohne zu trocknen, in einer mit Kreide neutralisierten Diazolösung, welche
2,9 g p-Chlor-o-toluidin oder
4,4 g   p-Chlor-o-aminodiphenyläther   im Liter enthält, entwickelt, gespült und geseift. 



   Man erhält so mit beiden   Aminobasen   klare, rote   Färbungen   von   sehr guter Bäuchechtheit.   
 EMI1.3 
 erzeugt werden. 



   Mit anderen entsprechenden,   chlorierten Aminobasen kann   das Verfahren in der gleichen Weise durchgeführt werden.

  Process for producing true colorations on vegetable fibers.



   In the German patent specification No. 256999 and a number of others, dyes are described which are formed by combining unsulfated diazo compounds with 2,3-oxynaphthoic acid arylides and can serve, among other things, to produce valuable colorations on fiber materials.



   It has now been found that particularly valuable dyeings are obtained if the fiber impregnated with a solution of the 2,3-oxynaphthoic acid-ß-naphthalide is treated with the diazo compounds of amino bases which have substituents in the 2,5-position to the amino group of at least one of which is a chlorine atom. Suitable bases are e.g. B. possible: p-chloro-o-toluidine
 EMI1.1
 CI = 1: 2: 5) etc.



   In addition to a clear shade and good fastness properties, the dyes obtained in this way are particularly notable for their excellent stomach fastness.



   Example: Well-boiled and dried yarn is mixed with a solution of
 EMI1.2
 
8 cc Turkish red oil per liter, impregnated, carefully wound and, without drying, in a diazo solution neutralized with chalk, which
2.9 g of p-chloro-o-toluidine or
4.4 g of p-chloro-o-aminodiphenyl ether per liter contains, developed, rinsed and soaped.



   In this way, with both amino bases, clear, red dyeings of very good tummy fastness are obtained.
 EMI1.3
 be generated.



   The process can be carried out in the same way with other corresponding, chlorinated amino bases.
