    <SEP> was found <SEP>, <SEP> that <SEP> man <SEP> one
<tb> receives new, <SEP> valuable <SEP> azo dye <SEP>, <SEP> if

EMI0001.0004
  
EMI0001.0005
  
    The <SEP> new <SEP> azo dye <SEP> is <SEP> particularly suitable for <SEP>, <SEP> for <SEP> coloring <SEP> of <SEP> cellulose esters <SEP> and
<tb> -äthe, rn, <SEP> where <SEP> man <SEP> clear <SEP> ruby red <SEP> tones <SEP> of

<tb> Dispensing medium <SEP> so <SEP> fine <SEP> in <SEP> ZVasser <SEP> distribute,
<tb> that <SEP> one receives <SEP> colloidal <SEP> solutions <SEP>, <SEP> the <SEP> itself
<tb> does not distinguish <SEP> from <SEP> real <SEP> solutions <SEP>.
<tb> Solehe <SEP> solutions <SEP> have <SEP> an <SEP> excellent
<tb> Durehfärbebarkeit, gen <SEP> for <SEP> Dichtgeschla.g@enes Acetatseidengeweibe and strongly twisted acetate silk yarn.



  <I> Example: </I> The diazo compound from 172.5 parts of l.-amino-2-chloro-4-nitrobenzene is slowly added to the solution of 264 parts diluted with water to about 5000 parts at 0 to 5 C N-ethyl-N-3-methyl-phenylaminopropioonic acid-ss'-oxyethyl ester poured into 110 parts of 35% hydrochloric acid.

   The formation is over after a few hours. Sodium acetate or dilute sodium hydroxide solution is added so that the pH of the solution is 5, suctioned off, washed well, dried at 50 ° C. and ground with the same amount of a dispersant.



  The dyestuff forms a black powder and, from aqueous baths containing Glauber's salt or chlorammonium, produces strong ruby-red colorations on acetate silk, which: are well dyed and lightfast. '
