Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 210606.    Verfahren zur Herstellung eines     Triphenylmethanfarbstoffes.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines sauren,  violetten     Triphenylmethanfarbstoffes.    Das  Verfahren ist dadurch gekennzeichnet, dass  man den     Farbstoff    folgender Konstitution  
EMI0001.0004     
    mit     5-Arnino-2-oxybenzoesänre    umsetzt. Der  neue Farbstoff färbt Wolle und Seide in     schi-          klaren,    violetten Tönen von der Lichtecht  heit 4.  



  <I>Beispiel:</I>  15 g des     Farbstoffes    folgender Konstitution  
EMI0001.0009     
    werden in 75     ems        Pyridin        -{--    15 cm' Wasser  mit 6,3 g     5-Amino-2-oxybenzoesäure    15 Stun  den lang auf dem kochenden Wasserbade  erwärmt. Nach dem Erkalten wird der in  goldgelben Kristallen ausgeschiedene Farb  stoff     genutscht,    mit salzsäurehaltigem Wasser  das     Pyridin    ausgewaschen und der Farbstoff  getrocknet. Er färbt Wolle und Seide in sehr  klaren Tönen violett von der     Lichtechtheit    4.



  <B> Additional patent </B> to main patent no. 210606. Process for the production of a triphenylmethane dye. The present patent relates to a process for the preparation of an acidic, violet triphenylmethane dye. The method is characterized in that the dye of the following constitution
EMI0001.0004
    with 5-amino-2-oxybenzoesänre implemented. The new dye dyes wool and silk in clear, violet shades of lightfastness 4.



  <I> Example: </I> 15 g of the dye of the following constitution
EMI0001.0009
    are heated in 75 ems pyridine - {- 15 cm 'water with 6.3 g of 5-amino-2-oxybenzoic acid for 15 hours on the boiling water bath. After it has cooled down, the dyestuff precipitated in golden yellow crystals is sucked off, the pyridine is washed out with water containing hydrochloric acid and the dyestuff is dried. It dyes wool and silk in very clear shades of violet with a lightfastness rating of 4.
