  Process for the preparation of a nonoazo dye. The present invention relates to a method for producing a monoaza color staff. The process is characterized in that diazotized 1-amino # b # enzene-2,5-disulfone, acid, acid with 1-phenyl-3-meth # 1-5-pyrazolone <B> - </B> 3 ', 5'- di <B> - </B> (sulf <B> -ss- </B> ehloroethylamide) couples.



  The dye is a yellow, water-soluble powder and dyes wool from acidic baths yellow. <I> Example: </I>
EMI0001.0018
  
    <B> 25.2 </B> <SEP> egg - weight parts <SEP> 1-amine # abovezol-2,5-disulfonic acid <SEP> are <SEP> diazotized. <SEP> The <SEP> diazo connection <SEP> leaves <SEP> one <SEP> in <SEP> a <SEP> egg8-cold, <SEP> aqueous

EMI0001.0019
    run in the presence of sodium acetate.

    When the coupling is complete, the dye staff is removed and finished as usual. It is a yellow, water-soluble powder and dyes wool from acidic pure. Bath greenish yellow; the dyeing is irrelevant and has very good wash fastness in c, c, light-colored laundry, both in terms of bleeding on white and in preservation of the color ion and the depth of color.
