Description

Verfahren zur Verbesserung der Lichtechtheit basischer Färbungen Es wurde gefunden, daß durchNachbehandlung basischer Färbungen mit Reduktionsprodukten komplexer Molybdä nwolframverbindungen die Lichtechtheit basischer Farbstoffe bedeutend erhöht wird.Process for improving the lightfastness of basic dyeings Es it was found that by post-treating basic dyeings with reduction products complex molybdenum tungsten compounds significantly increase the lightfastness of basic dyes is increased.

Beispiel Eine iprozentige Ausfärbung von Rhodamin B extra (Schultz, Farbstofftabellen [19i41, Nr.573) auf Tannin-Antimonbeize wird % Stunde bei So bis 6o° mit einer Lösung von o, i bis o,a g der z. B. durch Reduktion des Natronsalzes der Komplexsäure 24 (WO.- -f- MO 0:,) 3 H, 0, # P:; O, mit Hilfe von Natriumbisulfitlösung in der Wärme erhältlichen Phosphorwolframmolybdänverbindung in ioo ccm Wasser nachbehandelt und, ohne zu spülen, getrocknet. Die Färbung ist bedeutend lichtechter als eine nicht behandelte.EXAMPLE A percent coloring of Rhodamine B extra (Schultz, color tables [19i41, no.573) on tannin-antimony stain is used for% hour at So to 60 ° with a solution of o, i to o, ag of z. B. by reducing the sodium salt of complex acid 24 (WO.- -f- MO 0 :,) 3 H, 0, # P :; O, post-treated with the help of sodium bisulfite solution in the heat obtainable phosphorus tungsten molybdenum compound in 100 cc of water and dried without rinsing. The coloration is significantly more lightfast than one that has not been treated.
