  Zusatzpatent zum     ]Elauptpatent        Nr.   <B>210606.</B>    Verfahren zur Herstellung eines     Tripheuylmethaufarbstoffes.       Gegenstand. des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines sauren,  violetten     Triphenylmethanfarbstoffes.    Das  Verfahren ist dadurch gekennzeichnet,     dass     man den Farbstoff folgender Konstitution  
EMI0001.0006     
    mit     S-Sulfo-5-amino-2-oxybenzoesäure    um  setzt.

   Der neue Farbstoff färbt Wolle und  Seide in blaustichig violetten Tönen mit der  Lichtechtheit 4-5. e  <I>Beispiel:</I>  <B><I>6</I> g</B> des Farbstoffes folgender Konstitution:  
EMI0001.0008     
    werden in<B>30</B>     em,9        Pyridin   <B>+ 15</B> cm' Wasser  mit 4<B>g</B>     3-Sulfo-5-amino-2-oxybenzoesäure   <B>15</B>  Stunden lang auf<B>95-100</B>     '1        C    erwärmt. Dar  auf wird die Schmelze in<B>300</B>     ems    heisses  Wasser eingetragen,     ausgesalzen,        genutscht     und der Farbstoff getrocknet.

  Additional patent to] Elauptpatent No. <B> 210606. </B> Process for the production of a tripheuylmethane dye. Object. of the present patent is a method of making an acidic, violet triphenylmethane dye. The method is characterized in that the dye of the following constitution
EMI0001.0006
    with S-sulfo-5-amino-2-oxybenzoic acid sets.

   The new dye dyes wool and silk in bluish violet tones with a lightfastness of 4-5. e <I> Example: </I> <B> <I> 6 </I> g </B> of the dye of the following constitution:
EMI0001.0008
    are in <B> 30 </B> em, 9 pyridine <B> + 15 </B> cm 'of water with 4 <B> g </B> 3-sulfo-5-amino-2-oxybenzoic acid <B> Heated to <B> 95-100 </B> '1 C for 15 hours. Then the melt is poured into <B> 300 </B> ems hot water, salted out, suction filtered and the dye is dried. It dyes wool and silk in bluish violet tones with a lightfastness of 4-5.
