Description

Verfahren zur Herstellung von Lacken und 1Vlassen aus Nitrocellulosen In den Patentschriften 515 057 und 516 315 sind Verfahren zur Herstellung von Lacken und Massen aus Nitrocellulosen beschrieben, darin bestehend, daß man die Lacke oder Massen mit Farbstoffen, die aus salzsauren, dialkvlierten Nitrosoanilinen einerseits und dialkylierten m Aminokresolen oder monoalkylierten m-Aminophenolen anderseits erhältlich sind, färbt.Process for the production of lacquers and lacquers from nitrocelluloses The patents 515 057 and 516 315 describe processes for the production of lacquers and compositions from nitrocelluloses, which consist in that the lacquers or compositions are dialkylated with dyes made from hydrochloric acid, dialkylated nitrosoanilines on the one hand On the other hand, m aminocresols or monoalkylated m-aminophenols are obtainable, colors.

Es wurde nun gefunden, daß man durch gemeinsames Färben mit den nach den Verfahren der genannten Patentschriften erhältlichen blauen Oxazinfarbstoffen und Dinitrodiphenylaminen zu Grüntönen gelangt, welche in N itrocellulose sehr gut lichtecht sind. Dieses Ergebnis war keinesfalls vorauszusehen, da die beschriebenen blauen Oxazinfarbstoffe mit allen anderen, an sich in Nitrocellulose lichtechten gelben Farbstoffen gemischt, Grüntöne liefern, welche eine schlechte Lichtechtheit in Nitrocellulose besitzen.It has now been found that by dyeing together with the after blue oxazine dyes obtainable by the processes of the patents mentioned and dinitrodiphenylamines come to green tones, which in nitrocellulose do very well are lightfast. This result was by no means to be foreseen, since the described blue oxazine dyes with all others, per se lightfast in nitrocellulose mixed yellow dyes, give green tones, which have poor lightfastness in nitrocellulose.

Beispiele. I . 0,5 g Oxazinfarbstoff aus salzsaurem Nitroso-m-äthoxydiäthylanilin und m-oxyäthylanilin sowie 0,5 g 2, 4.-Dinitrodiphenylamin werden in 2509 Zaponlack unter schwachem Erwärmen gelöst.Examples. I. 0.5 g of oxazine dye from hydrochloric acid nitroso-m-ethoxydiethylaniline and m-oxyethylaniline and 0.5 g of 2,4-dinitrodiphenylamine are dissolved in 2509 Zapon varnish with gentle heating.

2. 0,5 g des Farbstoffes 2'-Dimethylamino-2-diäthylamino-3-methyloxazinchlorid und o,5 g 2, d-Dinitrodiphenylamin werden in 25o g Zaponlack unter schwachem Erwärmen gelöst.2. 0.5 g of the dye 2'-dimethylamino-2-diethylamino-3-methyloxazine chloride and 0.5 g of 2, d-dinitrodiphenylamine are placed in 250 g of zapon varnish with gentle heating solved.
