 bemerken ist. 



   Diese beidon Thatsachen sind technisch von grösster Bedeutung, da es auf diese Weise ermöglicht ist, selbst tiefe Färbungen auf dem verschiedensten Papiermaterial herzustellen, ohne gefärbte Abwässer zu haben-ein Umstand, der von allergrösster Bedeutung für die Papierfabriken ist-andererseits können bei der absoluten Wasserechtheit der erzielten Färbungen melierte Papiere mit mehrfarbigen Effectfasern bei z. B. absolut weissem Grund hergestellt werden und man kann ferner die sog. Ingrainpapiere mit 
 EMI2.2 
 begrenztem Gehalt an Melierfasern herstellen. 



   Das Färben geschieht, wie schon oben erwähnt, genau in derselben Weise, wie das Färben von Baumwolle im kochenden Bade und die Färbungen können des weiteren auf sonst übliche Weise nachbehandelt werden, wie z.   B.   durch   Behandlung mit Mctallsalzen,   Diazoverbindungen, Solidogen A pat. oder   durch   Weiterdiazotieren und Kuppeln des Farbstoffes auf der Faser.

 notice is.



   These two facts are technically of the greatest importance, since in this way it is possible to produce even deep colorations on the most varied of paper materials without having colored waste water - a circumstance which is of the greatest importance for the paper mills - on the other hand, with absolute waterfastness the colorations achieved mottled papers with multicolored effect fibers in z. B. absolutely white ground and you can also use the so-called Ingrain papers
 EMI2.2
 produce a limited content of mottled fibers.



   The dyeing takes place, as already mentioned above, exactly in the same way as the dyeing of cotton in a boiling bath and the dyeings can furthermore be aftertreated in the usual way, such as B. by treatment with metal salts, diazo compounds, Solidogen A pat. or by further diazotizing and coupling the dye on the fiber.
