Description

  

      Zusatzpatent    zum Hauptpatent Nr. 215148.         Terfahren    zur Herstellung eines wasserlöslichen basischen Farbstoffes.    Gegenstand vorliegender Erfindung ist  ein Verfahren zur Herstellung eines wasser  löslichen basischen Farbstoffes. Das Ver  fahren besteht darin, dass man     1-Methyl-2-          phenylindol-3-aldehyd    mit     5-Brom-1,3,3-tri-          methyl-2-methylenindolin    umsetzt.  



  Der Farbstoff stellt ein gut kristallisier  tes Pulver dar, das sich in Wasser und Al  kohol gut löst und tannierte Baumwolle und       Acetatseide    in orangen Tönen färbt.  



  <I>Beispiel:</I>  11,8 Gewichtsteile     1-Methyl-2-phenyl-          indol-3-aldehyd    und 12,6 Gewichtsteile 5  Brom-1,3,3-trimethyl-2-methylenindolin wer  den in Eisessig gelöst und einige Stunden  auf<B>100'</B> erhitzt. Man giesst die Lösung in  Wasser und salzt aus. Das so erhaltene Roh  produkt wird erneut in heissem Wasser ge  löst, von unlöslichen harzigen Bestandteilen  abgetrennt und     ausgesalzen.    Man erhält den    Farbstoff schön kristallinisch. Er ist in Was  ser und Alkohol gut löslich. Tannierte Baum  wolle und     Acetatseide    färbt er in orangen  Tönen an.

   Das Umsetzungsprodukt mit     Phos-          phor-Wolfram-Molybdänsäure    liefert einen  besonders klaren, licht- und     spritechten        Farb-          lack.  



      Additional patent to the main patent No. 215148. The process for the production of a water-soluble basic dye. The present invention relates to a process for the preparation of a water-soluble basic dye. The process consists in reacting 1-methyl-2-phenylindole-3-aldehyde with 5-bromo-1,3,3-trimethyl-2-methyleneindoline.



  The dye is a well-crystallized powder that dissolves well in water and alcohol and dyes tannic cotton and acetate silk in orange tones.



  <I> Example: </I> 11.8 parts by weight of 1-methyl-2-phenyl-indole-3-aldehyde and 12.6 parts by weight of 5-bromo-1,3,3-trimethyl-2-methylene-indoline are dissolved in glacial acetic acid and heated to <B> 100 '</B> for a few hours. The solution is poured into water and salted out. The raw product thus obtained is redissolved in hot water, separated from insoluble resinous components and salted out. The dye is obtained in a nicely crystalline form. It is easily soluble in water and alcohol. He dyes tannic cotton and acetate silk in orange tones.

   The reaction product with phosphorus-tungsten-molybdic acid provides a particularly clear, lightfast and spritable colored lacquer.
