Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>110287.</B>    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     dass    man einen neuen  Farbstoff erhält, wenn man die     diazotierte          2-Aminobenzol-l-p-toluolsulfon-4-sulfosäure     mit     3-Aminonaphthalin-1,8-dikarbonsäure    ver  einigt. Der neue Farbstoff bildet ein brau  nes Pulver, das sich in Wasser mit roter, in  Schwefelsäure mit     gelbbranner    Farbe löst.  Im Chromdruck auf Baumwolle erzeugt er  reine, rote Töne.

      <I>Beispiel:</I>    <B>10,7</B> Teile     3-Aminonaplithalin-1,8-clilzar-          bonsä,ureanllydrid    werden mit Hilfe von<B>10</B>  Teilen<B>30</B>     %iger    Natronlauge in<B>1.50</B> Teilen  Wasser heiss gelöst, mit<B>10</B> Teilen Soda, ver  setzt, abgekühlt und mit der aus<B>16,3</B> Teilen       2-Aminobenzol-l-p-toluols-Lilfon-4-sulfosäure       hergestellten     Dia-zoverbindung    versetzt. Nach  erfolgter Kupplung wird der Farbstoff     a-us-          gesalzen,    filtriert und getrocknet.



  Additional patent to main patent no. <B> 110287. </B> Process for the production of a new dye. It has been found that a new dye is obtained if the diazotized 2-aminobenzene-1-p-toluenesulfone-4-sulfonic acid is combined with 3-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a brown powder that dissolves in water with a red color and in sulfuric acid with a yellowish-brown color. In the chrome print on cotton it creates pure, red tones.

      <I> Example: </I> <B> 10.7 </B> parts of 3-aminonaplithalin-1,8-clilzar- bonsa, ureanllydride are converted into <B> 10 </B> parts <B> 30 </B>% sodium hydroxide solution dissolved in <B> 1.50 </B> parts of hot water, mixed with <B> 10 </B> parts of soda, cooled and mixed with the <B> 16.3 </ B > Parts of 2-aminobenzene-lp-toluene-Lilfon-4-sulfonic acid produced dia-zo compound added. After coupling has taken place, the dye is salted out, filtered and dried.
