  Zusatzpatent zum Hauptpatent     Nr.    114283.    Verfahren zur Herstellung eines neuen     Farbstoffes.       <B>Es</B> wurde gefunden,     dass        man    einen  neuen Farbstoff erhält, wenn man die  jenige     u.-Naphthylbarbitursäure,    welche aus       u,-Xkaphthylharnstoff    und     Malonester    erhal  ten wird, mit     diazotierter        4-Chlor-'2?-amino-          1-phenol-ä-sulfosb,ure    kuppelt und das so  erhaltene Produkt mit     Fluorchrom    be  handelt.

   Der neue Farbstoff bildet ein  braunes Pulver, löst sich in     verdüunter        Soda-          Lösung    mit     rotoranger    Farbe und erzeugt  auf Wolle, aus saurem Bade gefärbt, echte  rotorange Töne.  



       Beispiel-          224    Teile     4-Chlor-9--amino-l-pheiiol-5-          sulfosäure    werden wie üblich     diazotiert     und in ein Gemisch aus<B>267</B> Teilen     a-          Naplithylbarbitursäure,   <B>133</B> Teilen<B>30</B>     '/oiger     Natronlauge,<B>170</B> Teilen Soda und<B>1500</B> Tei  len Wasser eingetragen. Die Kupplung setzt  sofort ein; zu ihrer Vervollständigung rührt  man noch einige Zeit. Der gebildete Farb  stoff wird dann filtriert und getrocknet.

      <B>50,2</B> Teile dieses Farbstoffes werden in  <B>650</B> Teilen kochendem Wasser gelöst und  mit einer,     Fluorcl:Üomlösung,    entsprechend  <B>15,2</B> Teilen     Cr,O"        versetzt.o    Man     hocht     mehrere Stunden am     Rückflusskühler,    dampft  teilweise ein -und gewinnt die neue Chrom  verbindung durch Filtrieren, gegebenenfalls  -unter vorherigem     Aussalzen.  



  Additional patent to main patent No. 114283. Process for the production of a new dye. It has been found that a new dye is obtained if the u-naphthylbarbituric acid, which is obtained from u, -Xcaphthylurea and malonic ester, is mixed with diazotized 4-chloro-2? -Amino - 1-phenol-a-sulfosb, ure couples and treats the product thus obtained with fluorochrome.

   The new dye forms a brown powder, dissolves in diluted soda solution with a red-orange color and creates real red-orange tones on wool dyed from an acid bath.



       Example 224 parts of 4-chloro-9-amino-1-phenol-5-sulfonic acid are diazotized as usual and converted into a mixture of <B> 267 </B> parts of α-naplithylbarbituric acid, <B> 133 </B> Parts <B> 30 </B> '/ oiger caustic soda, <B> 170 </B> parts soda and <B> 1500 </B> parts water. The clutch works immediately; stir for a while to complete them. The color formed is then filtered and dried.

      <B> 50.2 </B> parts of this dye are dissolved in <B> 650 </B> parts of boiling water and mixed with a fluorine solution, corresponding to <B> 15.2 </B> parts of Cr, O "Added. o The reflux condenser is heated up for several hours, partially evaporated and the new chromium compound is obtained by filtering, if necessary, with salting out beforehand.
