  Verfahren zur Herstellung eines     nachebromierbaren        Azofarbstoffes    der     Pyrazolonr-eibe.       Es     wurdegefunden,        dassman        durchKuppeln     von     diazotierter        2-Amino-l-pheriol-4-sulfo-6-          karbonsäure    mit     1(3'-Karboxyl-)phenyl-5-pyr-          azolon-3-karbonsäure    einen     nachchromierbaren          Azofarbstoff    erhält,

   welcher auf Wolle     nach-          chromiert    reine orange Töne gibt und bei  dem Chromdruck auf Baumwolle orangerote  Töne von sehr guter Seifen-, Chlor- und  Lichtechtheit erzeugt.    <I>Beispiel:</I>  <B>23,3</B> Teile     2-Amino-1-plienol-4-sulfo-6-          karbonsäure    werden auf übliche Weise     dia-          zotiert.    Die     Diazoverbindung    wird in eine  konzentrierte     wässrige    Lösung von 26 Teilen       1(3'-Karboxyl)

          -phenyl-    5     -pyrazolon-3-karbon-          säure    und 30 Teile Soda     eingetragen.    Nach    vollendeter Kupplung wird der     Farbstoff        durch     Zusatz von Kochsalz ausgeschieden, filtriert,  gepresst und getrocknet.



  Process for the production of a post-brominable azo dye of the pyrazolone pulp. It has been found that by coupling diazotized 2-amino-1-pheriol-4-sulfo-6-carboxylic acid with 1 (3'-carboxylic) phenyl-5-pyrazolone-3-carboxylic acid, a post-chromable azo dye is obtained,

   which, when chromed on wool, gives pure orange tones and, with the chrome print on cotton, produces orange-red tones of very good soap, chlorine and lightfastness. <I> Example: </I> <B> 23.3 </B> parts of 2-amino-1-plienol-4-sulfo-6-carboxylic acid are diazotized in the usual way. The diazo compound is dissolved in a concentrated aqueous solution of 26 parts of 1 (3'-carboxyl)

          -phenyl- 5 -pyrazolon-3-carbonic acid and 30 parts of soda are registered. After coupling is complete, the dye is separated out by adding sodium chloride, filtered, pressed and dried.
