Verfahren zur Darstellung von ätzbaren Azofarbstoffen auf der Faser.
Es wurde gefunden, dass man wertvolle Färbungen auf Baumwolle erhält, wenn man die Diazoverbindungen von halogenierten Aminobenzolsulfosäuren mit na-Diaminen kuppelt und die so erhaltenen Produkte mit Nitrodiazobenzol auf der Faser entwickelt. Die Färbungen zeichnen sich durch kräftige und klare, gelbbraune bis rotbraune. zum Teil kupferähnliche Nuancen aus ; sie sind sehr gut ätzbar, wasch-und säureecht ; auch die Lichtechtheit ist vorzüglich.
Beispiel.
EMI1.1
gestelltes, auf ein Liter gebrachtes Bad passieren, welches 14 9 p-Nitrani1in und 40 g kristallisiertes Natriumazetat gelöst enthält. Nach dem Waschen, Seifen und Trocknen erhält man ein kräftiges Rotbraun von den angegebenen guten Echtheitseigenschaften.
In ganz. analoger Weise werden die Färbungen mit anderen Farbstoffen aus dia- zotierten ha) ogenierten Aminohenzo ! sutfosäuren und m-Diaminen hergestellt.
Als halogenierte Aminobenzolsulfosäuren kommen z. B. ausser der genannten noch in Betracht : die 4-Chloranilin-3-sulfosäure, die 3-Brom-2-toluidin-5-sulfosäure. die 2. 5-Dichlor- anilin-4-sulfosäure.

Process for the representation of etchable azo dyes on the fiber.
It has been found that valuable dyeings on cotton are obtained if the diazo compounds of halogenated aminobenzene sulfonic acids are coupled with na-diamines and the products thus obtained are developed on the fiber with nitrodiazobenzene. The colors are strong and clear, yellow-brown to red-brown. partly copper-like nuances; they are very easy to etch, washable and acid-proof; the lightfastness is also excellent.
Example.
EMI1.1
Pass the provided bath made up to one liter, which contains 14 9 p-nitroanine and 40 g of crystallized sodium acetate dissolved. After washing, soaping and drying, a strong reddish brown with the stated good fastness properties is obtained.
In whole. in an analogous manner, the dyeings with other dyes from diazotized ha) ogenated Aminohenzo! sutfoic acids and m-diamines.
As halogenated aminobenzene sulfonic acids come z. B. in addition to the mentioned: 4-chloroaniline-3-sulfonic acid, 3-bromo-2-toluidine-5-sulfonic acid. 2. 5-dichloro-aniline-4-sulfonic acid.
