Description

  

  Verfahren zur Tierstellung eines für den Chromdruck auf Baumwolle besonders  geeigneten     Azofarbstoffes.       Es wurde gefunden, dass     man    durch Kup  peln von     dia.zotierter        1-OYy-2-,amino-4-chlor-          benzol-5-sulfosäure    mit     Resorcylsäure    einen       Azofarbstoff    .erhält, welcher bei dem Chrom  druck auf Baumwolle     violettbraune    Töne von  sehr guten     Echtlieiten    erzeugt.  



       Beispiel:     Die .auf übliche Weise dargestellte     Dia-          zoverbind        ung    aus<B>22,3</B> Teilen     1-OYy-2-amino-          4-chlorbenzol-5-sulfosäure    lässt man in eine  Lösung von 15,4 Teilen     Resorcylsäure    und  30 Teilen Soda einfliessen. Durch Neutrali  sation mit Mineralsäuren lässt sieh der Farb  stoff fällen.  



  Der neue Farbstoff löst sich in Wasser  mit gelbbrauner Farbe, welche Lösung auf  Zusatz von Soda blaurot wird; in konzen  trierter Schwefelsäure löst er sich rot. Beim    Chromdruck auf     Baumwolle        erzeugt    er     vio-          lettbraune    Töne von sehr guten     Bchtheiten.  



  Method for making animals of an azo dye particularly suitable for chrome printing on cotton. It has been found that by coupling dia.zotierter 1-OYy-2-, amino-4-chlorobenzene-5-sulfonic acid with resorcylic acid, an azo dye is obtained which, with the chrome print on cotton, has very good violet-brown tones Real love generated.



       Example: The diazo compound prepared in the usual way and made from 22.3 parts of 1-OYy-2-amino-4-chlorobenzene-5-sulfonic acid is left in a solution of 15.4 parts of resorcylic acid and pour in 30 parts of soda. Neutralization with mineral acids causes the dye to precipitate.



  The new dye dissolves in water with a yellow-brown color, which solution turns blue-red on addition of soda; it dissolves red in concentrated sulfuric acid. When printing chrome on cotton, it produces violet-brown tones of very good fastness.

PATENTANSPRUCH: Verfahren zur Herstellung eines für den Chromdruck auf Baumwolle besonders geeig neten Azofarbstoffes, dadurch gekennzeich net, dass diazotierte 1-Oxy-2-amino-4-chlor- beiizol-5-sulfosäure mit Resorcylsäure gekup pelt wird. Der neue Farbstoff löst sich in Wasser mit gelbbrauner Farbe, welche Lösung auf Zusatz von Soda blaurot wird; in konzen trierter Schwefelsäure löst er sich rot. PATENT CLAIM: Process for the production of an azo dye particularly suitable for chromium printing on cotton, characterized in that diazotized 1-oxy-2-amino-4-chloro-beiizole-5-sulfonic acid is coupled with resorcylic acid. The new dye dissolves in water with a yellow-brown color, which solution turns blue-red on addition of soda; it dissolves red in concentrated sulfuric acid. Beim Chromdruck auf Baumwolle erzeugt er vio- lettbraune Töne von sehr guten Echtheiten. When printing chrome on cotton, it produces violet-brown tones with very good fastness properties.
