Description

  

  Verfahren zur Herstellung einer     1VIonoazofarbstoffsulfonsäure.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung einer     Monoazo-          farbstoffsulfonsäure,    dadurch gekennzeich  net, dass man die     Diazoverbindung    von       1-Aminobenzol    - 3 -     carbonsäure-        dicyklohegyl-          amid    mit     1-(2'-Sulfophenyl)-3-phenyl-5-pyr-          azolon    vereinigt.  



  Der getrocknete Farbstoff ist ein wasser  lösliches     rotstichig    gelbes Pulver     und    färbt  Wolle aus neutralem Bade in sehr echten       rotstichig    gelben Tönen von besonders guter  Lichtechtheit.  



  <I>Beispiel:</I>  30 Teile     1-Aminobenzol-3-carbonsäure-          dicyklohegylamid    werden     diazotiert.    Die       Diazolösung    vereinigt man mit einer     soda-          alkalischen        Lösung    von 37 Teilen 1-(2'-Sulfo-         phenyl)-3-phenyl-5-pyrazolon.    Der erhaltene  Farbstoff wird abgeschieden und getrocknet.



  Process for the preparation of a 1Vionoazo dye sulfonic acid. The present patent relates to a process for the preparation of a monoazo dye sulfonic acid, characterized in that the diazo compound of 1-aminobenzene - 3 - carboxylic acid dicyklohegyl amide with 1- (2'-sulfophenyl) -3-phenyl-5- pyr-azolone combined.



  The dried dye is a water-soluble reddish yellow powder and dyes wool from a neutral bath in very genuine reddish yellow shades of particularly good lightfastness.



  <I> Example: </I> 30 parts of 1-aminobenzene-3-carboxylic acid dicyklohegylamide are diazotized. The diazo solution is combined with a soda-alkaline solution of 37 parts of 1- (2'-sulfophenyl) -3-phenyl-5-pyrazolone. The dye obtained is deposited and dried.
