  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 198713.    Verfahren     zur    Darstellung eines     ehromierbaren    Farbstoffes der     Triarylmethanreihe.            Gegenstand    dieses     Zusatzpatentes    ist ein  Verfahren zur Darstellung     eines        chromier-          baren        Farbstoffes    der     Triarylmethanreihe,     welches dadurch gekennzeichnet ist,

   dass man       methyläthylamino    - m -     phenol    -     co    -     sulf        onsaures     Natrium mit     5-Ogytrimellithsäureanhydrid     kondensiert.    <I>'</I>     Beispiel:     65     Gewichtsteile        5-Ogytrimellithsäure-          anhydrid    werden mit<B>82</B> Gewichtsteilen me-         thylamino-m-phenol-u)-sulfonsaurem        Natrium     4 Stunden auf     180-190'    C erhitzt.

   Die     pul-          verisierte,Schmelze    wird zur Entfernung der       überschüssigen        5-Ogytrimellithsäure    mit 200  Gewichtsteilen Alkohol kurze Zeit in der  Wärme behandelt und nach dem Erkalten       abgesaugt.    Der Rückstand wird in     etwa    100       Gewichtsteilen        Wasser-,gelöst,    die     Lösung    fil  triert     und    der Farbstoff mit     Kochsalz        aus-          g:esalzen:

      Der rote Farbstoff besitzt folgende  Konstitution

           und    färbt Wolle aus saurem Bade in sehr  klaren     blaustichigroten    Tönen, die durch       Nachchromieren    in ihren     Echtheiten    verbes  sert werden.



  <B> Additional patent </B> to the main patent No. 198713. Process for the preparation of an honorable dye of the triarylmethane series. The subject of this additional patent is a process for the preparation of a chromable dye of the triarylmethane series, which is characterized by

   that methylethylamino - m - phenol - co - sulfonate sodium is condensed with 5-Ogytrimellitic anhydride. <I> '</I> Example: 65 parts by weight of 5-ogytrimellitic anhydride are heated with <B> 82 </B> parts by weight of methylamino-m-phenol-u) -sulphonic acid at 180-190 ° C. for 4 hours .

   To remove the excess 5-ogytrimellitic acid, the pulverized melt is treated with 200 parts by weight of alcohol under heat for a short time and, after cooling, is suctioned off. The residue is dissolved in about 100 parts by weight of water, the solution is filtered and the dye is salted out with common salt:

      The red dye has the following constitution
EMI0001.0038
           and dyes wool from an acid bath in very clear blue-tinged red tones, the fastness of which is improved by re-chrome plating.
