Description
Verfahren zur Herstellung eines PolymethinfarbstofPes. In der Hauptanmeldung ist ein Verfah ren zur Herstellung eines neuen Polymethin- farbstoffes beschrieben, bei dem man 1,3,3- Trimethyl-2-methylenindolin-co-aldehyd in Gegenwart eines sauren Kondensationsmittels mit p-Phenylendiamin umsetzt.
Es wurde nun gefunden, dass tnan eben falls einen neuen wertvollen Polymethinfarb- stoff erhält, wenn man 1,3,3-Trimethyl-2- methylenindolin-co-aldehyd in Gegenwart eines sauren Kondensationsmittels mit p- Phenetidin umsetzt.
Der neue Farbstoff ähnelt den basischen Triphenylmethanfarbstoffen der Auraminreihe. Er ist gut wasserlöslich und zeichnet sich durch ausgezeichnete Klarheit und sehr gute Lichtechtheit seiner Färbungen aus. Durch Sulfonierung kann man den Farbstoff in einen wertvollen sauren Farbstoff überführen. 21 Teilen 1,3,3-Trimethyl-2-methylenicidolin- o)-aldehyd versetzt und '/s Stunde lang auf <B>950</B> C erwärmt. Der nach dem Erkalten der Lösung auskristallisierte Farbstoff wird ab gesaugt, mit wenig Wasser gewaschen und getrocknet.
Er färbt tannierte Baumwolle in reinen grüngelben Tönen von guter Licht- echtbeit.
Process for the preparation of a polymethine dye. In the main application, a method for producing a new polymethine dye is described in which 1,3,3-trimethyl-2-methyleneindoline-co-aldehyde is reacted with p-phenylenediamine in the presence of an acidic condensing agent.
It has now been found that a new, valuable polymethine dye is also obtained if 1,3,3-trimethyl-2-methyleneindoline-co-aldehyde is reacted with p-phenetidine in the presence of an acidic condensing agent.
The new dye is similar to the basic triphenylmethane dyes of the auramine series. It is readily soluble in water and its dyeings are characterized by excellent clarity and very good lightfastness. The dye can be converted into a valuable acidic dye by sulfonation. 21 parts of 1,3,3-trimethyl-2-methylenicidolin- o) -aldehyde are added and the mixture is heated to 950 ° C. for an hour. The dye which crystallizes out after the solution has cooled is filtered off with suction, washed with a little water and dried.
It dyes tannic cotton in pure green-yellow tones with good light-fastness.
