  Zusatzpatent zum Hauptpatent     Nr.   <B>278943.</B>    Verfahren zur Herstellung eines     Indolyl-diphenylmethaufarbstoffes.       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Herstellung eines       Indolyl   <B>-</B>     diphenylniethanfarbstoffes,    welches  dadurch gekennzeichnet ist,     dass    man     4,4'-Di-          chlorbenzoplienon-3,3'-di.-,

  ulfosäure    mit     1-Me-          thyl-2-phenylindol    in etwa molekularem Ver  hältnis kondensiert und das erhaltene Kon  densationsprodukt mit einem     übersehuss    von       p-Aminodiplienylamin    umsetzt.  



  <I>Beispiel:</I>  Man kondensiert<B>35</B>     Gewiehtsteile        4,4'-di-          chlorbenzophenon-3,3'-disullosaures    Natrium  mit 14,5     Gewiehtsteilen        1-Methyl-2-phenyl-          indol    in<B>150</B>     Gewiehtsteilen        301/oiger    Salz  säure 20 Stunden bei     60oC,

      saugt das rote  Zwischenprodukt ab und     versehmilzt    mit<B>150</B>  Gewichtsteilen     p-Aminodiphenylamin    bei Ge  genwart von Glykol<B>5</B> Stunden bei     9011   <B>C.</B> Die  überschüssige Base entfernt man durch Ex  traktion mit verdünnter Salzsäure, löst den    Farbstoff in verdünnter     Sodalösung    und salzt  mit Kochsalz aus.  



  Das so erhaltene Produkt stellt ein violett  glänzendes Pulver dar, das Wolle und Seide  in marineblauen Tönen von sehr guter Licht-,  Wasch- und     Walkeehtheit    färbt.



  Additional patent to main patent no. <B> 278943. </B> Process for the preparation of an indolyl-diphenylmethane dye. The subject of the present additional patent is a process for the preparation of an indolyl diphenylniethane dye, which is characterized in that 4,4'-dichlorobenzoplienone-3,3'-di.-,

  Sulphonic acid is condensed with 1-methyl-2-phenylindole in an approximately molecular ratio and the condensation product obtained is reacted with an excess of p-aminodiplienylamine.



  <I> Example: </I> <B> 35 </B> parts by weight of 4,4'-dichlorobenzophenone-3,3'-disullosauresodium are condensed with 14.5 parts by weight of 1-methyl-2-phenylindole in <B> 150 </B> parts by weight of 301 / o hydrochloric acid for 20 hours at 60oC,

      The red intermediate product is suctioned off and melted with <B> 150 </B> parts by weight of p-aminodiphenylamine in the presence of glycol for <B> 5 </B> hours at 9011 <B> C. </B> The excess base is removed by extraction with dilute hydrochloric acid, the dye dissolves in dilute soda solution and salted with table salt.



  The product obtained in this way is a shimmering violet powder which dyes wool and silk in navy blue shades of very good lightfastness, washfastness and looseness.
