EMI0001.0002
  
    The present <SEP> patent <SEP>, <SEP> refers to <SEP>
<tb> Process <SEP> for the <SEP> production <SEP> of an <SEP> acidic
<tb> wool azo dye - characterized by <SEP>,
<tb> that <SEP> one <SEP> diazotized <SEP> 1- (N-acetyl-isopropyl amino) -4-am # inobenzal <SEP> in <SEP> soda-alkaline
<tb> Medium <SEP> with <SEP> 1- (2'-chloro-5'-sulfophenyl) -6 methyl-5-pyrazolane <SEP> couples.
<tb>



  The <SEP> thus <SEP> obtained <SEP> dye <SEP> reproduces <SEP>
<tb> <SEP> drying <SEP> a <SEP> lemon yellow <SEP> water-soluble <SEP> powder <SEP> and <SEP> colors <SEP> wool <SEP> and <SEP> silk <SEP> in

<tb>



  <I> Example: </I>
<tb> 1,9,2 <SEP> parts <SEP> 1- (N-Acetyl-: isopTopylamina) 4-aminoibenzol <SEP> are <SEP> diazotized <SEP> as usual <SEP>.
<tb> The <SEP> received <SEP> diazo solution <SEP> is coupled <SEP> to <SEP> in
