  Zusatzpatent     ztim    Hauptpatent     Nr.    100479.    Verführen zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen neuen       -lzof,        arbstoff        herstellen        kann,        wenn        man        die          1)i#17overbilidulig    der     '2)-#,Imino-l-oxy-4-ben-          zolsulfosäure    mit     1-(3'-Suliamido)-phenyl-3-          mLthvl-5-pyrazolon    kuppelt.

   Der neue     Azo-          farb.,toff    bildet ein rotbraunes Pulver. Er  färbt Wolle in gelborangen Farbtönen,     wel-          ehe    beim     Nachehromieren        orancrerot    werden.  <B>CD</B>  <I>Beispiel:</I>  Die     Diazoverbinclung,    hergestellt aus       189Teilen        2-Amino-l-oxy-4-beiizolsulfosäure,     wird in eine abgekühlte Lösung von<B>253</B> Tei  len     1-(3'-Sulfamido,)-phenyl-3-methyl-5-pyr-          Izolon    und 200 Teilen Soda eingetragen.

  Additional patent to main patent no. 100479. Seduction to produce a new azo dye. It has been found that a new -lzof, dye can be produced if the 1) i # 17overbilidulig der '2) - #, imino-l-oxy-4-benzene sulfonic acid with 1- (3'-suliamido) -phenyl-3- mLthvl-5-pyrazolon couples.

   The new azo color, toff forms a red-brown powder. It dyes wool in yellow-orange hues which turn orange-red when re-homing. <B> CD </B> <I> Example: </I> The diazo compound, produced from 189 parts of 2-amino-1-oxy-4-bizolsulfonic acid, is poured into a cooled solution of <B> 253 </B> parts len 1- (3'-sulfamido,) - phenyl-3-methyl-5-pyr-izolone and 200 parts of soda entered.

           After prolonged stirring, the dye is salted out, filtered and dried.
