  Zusatzpatent zum Hauptpatent     Nr.   <B>205169.</B>    Verfahren zur Herstellung eines sauren     Farbstoffes    der     Triphenylmethanreihe.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Herstellung eines sauren Farb  stoffes der     Triphenylmethanreihe,    welches da  durch gekennzeichnet ist,

       dass    man den durch  Kondensation von     4.4'-Dichlorbenzophenon     mit     1-Isobutyl-2-p-chlorphenyl-4.6-dimethyl-          indol    erhältlichen     Ti-iphenylmethanfarbstoff    mit       1-Alethylamino-4-methoxybenzol    verschmilzt  und den so erhaltenen Farbstoff zur     Disulfon-          säure        sulflert.    Bei dieser Umsetzung tritt  <B>1</B>     Mol    des     Triphenylmethanfarbstoff    es mit 2     Mol          Methylaminometboxybenzol    in Reaktion.

      <I>Beispiel:</I>  Das durch Kondensation von 4.     4'-Dichlor-          benzophenon    mit     1-Isobutyl-2-p-chlorphenyl-          4.6-dimethyliridol    erhältliche Kondensations  produkt wird mehrere, z.

  Additional patent to main patent no. <B> 205169. </B> Process for the production of an acidic dye of the triphenylmethane series. The subject of this additional patent is a process for the production of an acidic dye of the triphenylmethane series, which is characterized by

       that the titanium phenylmethane dye obtainable by condensation of 4,4'-dichlorobenzophenone with 1-isobutyl-2-p-chlorophenyl-4,6-dimethylindole is fused with 1-alethylamino-4-methoxybenzene and the dye thus obtained is sulflert to disulfonic acid. In this reaction, 1 mole of the triphenylmethane dye reacts with 2 moles of methylaminomethboxybenzene.

      <I> Example: </I> The condensation product obtained by condensation of 4'-dichlorobenzophenone with 1-isobutyl-2-p-chlorophenyl-4,6-dimethyliridol is several, z. B. three hours, with excess 1-methylainino-4-methoxybenzene at 120 0 C and the resulting basic blue dye is cleaned by stirring with dilute hydrochloric acid.

    By sulfonating the paraffin with concentrated sulfuric acid at normal temperature to disulfonic acid, a dye is created that dyes wool and silk in greenish blue tones. The dye has true
