      Zusatzpatent    zum Hauptpatent     Nr.    114283.    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     dass        man    einen neuen  Farbstoff     erh5,1t,    wenn man diejenige     p-To-          #ylbarbitursäure,    welche aus     p-Tolylharlistof   <B>f</B>       und        Malonester    erhalten wird, mit     diazo-          tierter        '-#)-Amino-1-1)henol-4-sulfos#,

  i-tre    kup  pelt Lind das so erhaltene Produkt mit     Fluor-          ehrom    behandelt. Der neue Farbstoff bildet  ein rotbraunes Pulver, löst sieh in verdünnter       Sodalösung    mit     oranger    Farbe und erzeugt  auf Wolle, aus saurem Bade gefärbt, echte  rotorange Töne.  



  <I>Beispiel:</I>  <B>190</B> Teile,     2-Aniino-l-pheliol-4-sulfosä.ure     werden wie üblich     diazotiert    und in ein Ge  misch     aus   <B>228</B> Teilen     p-Tolylbarbitursäure,     <B>133</B> Teilen<B>30</B>     '/oiger    Natronlauge,<B>170</B> Teilen  Soda und<B>1500</B> Teilen Wasser eingetragen.  Die Kupplung setzt sofort ein, zu ihrer     Ver-          vollstä,ndigung    rührt man noch einige Zeit.  Der     "ebildete    Farbstoff wird dann filtriert       z#          und    getrocknet.

      <B>-12,9</B> Teile dieses Farbstoffes werden in  <B>650</B> Teilen kochendem Wasser gelöst und mit  einer     Fluorchromlösung    entsprechend<B>15,2</B>  Teilen     Cr,0,    versetzt. Man kocht mehrere  Stunden am     Rückf        lusskühler,    dampft teilweise  ein und gewinnt die neue Chromverbindung  durch Filtrieren, gegebenenfalls unter vor  herigem     Aussalzen.  



      Additional patent to the main patent No. 114283. Process for the production of a new dye. It has been found that a new dye is obtained if that p-To- # ylbarbituric acid, which is obtained from p-Tolylharlistof <B> f </B> and malonic ester, with diazotized '- #) - Amino-1-1) henol-4-sulfos #,

  i-tre couples and treats the product obtained in this way with fluorine-chromium. The new dye forms a red-brown powder, dissolves in a dilute soda solution with an orange color and produces real red-orange tones on wool dyed from an acid bath.



  <I> Example: </I> <B> 190 </B> parts of 2-aniino-l-pheliol-4-sulfonic acid are diazotized as usual and mixed into a mixture of <B> 228 </B> Parts of p-tolylbarbituric acid, <B> 133 </B> parts of <B> 30 </B> '/ oiger sodium hydroxide solution, <B> 170 </B> parts of soda and <B> 1500 </B> parts of water are added. The clutch starts immediately, and stir for some time to complete. The dye formed is then filtered off and dried.

      <B> -12.9 </B> parts of this dye are dissolved in <B> 650 </B> parts of boiling water and mixed with a fluorochrome solution corresponding to <B> 15.2 </B> parts of Cr.0. It is boiled for several hours on the reflux condenser, partially evaporated and the new chromium compound is obtained by filtering, if necessary with prior salting out.
