Description

Verfahren zur Herstellung lichtechter, blauer, transparenter Zaponlacke Gut lichtechte, transparente Zaponlacke in lebhaftem, blauem Farbton herzustellen, gelang bisher nicht, da ein geeigneter Farbstoff dafür noch nicht bekannt war.Process for the production of lightfast, blue, transparent Zapon varnishes Produce good lightfast, transparent Zapon varnishes in a lively, blue shade, has not yet been successful because a suitable dye for it was not yet known.

Es wurde nunmehr die überraschende Beobachtung gemacht, daß es gelingt, mit den Farbstoffen aus salzsauren dialkylierten Nitrosoanilinen und dialkylierten m-Aminokresolen (vgl. S chultz -j ulius, AuflageV Nr. 62o) Lacke oder plastische Massen aus Nitrocellulose in lebhaft grünlichblauem Farbton gut lichtechtanzufärben. Dieses Ergebnis war durchaus nicht vorauszusehen, da Farbstoffe ganz ähnlicher Konstitution, wie das Oxazin, aus Nitrosodialkyl-m-amino-p-kresol und m- oder p-Diaminen (s. Schultz Nr. 6-- 1) oder der Farbstoff aus Dialkylamin und Meldolablau (Nitrosodimethylanilin und ß-Naphthol, s. S c h u 1 t z Nr. 65 1) in Zaponlack vollkommen lichtunechte Färbungen ergeben. Beispiel i g 2-Dimethylamiiio-2'-diäthylamino-3'-methyloxazinchlorid werden in 25og Zaponlack unter schwachem Erwärmen gelöst.The surprising observation has now been made that it is possible to use the dyes made from hydrochloric acid dialkylated nitrosoanilines and dialkylated m-aminocresols (cf. S chultz-j ulius, Edition V No. 62o) to dye varnishes or plastic compositions made of nitrocellulose in a lively greenish-blue shade . This result could not be foreseen at all, since dyes of a very similar constitution, such as oxazine, made from nitrosodialkyl-m-amino-p-cresol and m- or p-diamines (see Schultz No. 6-1 ) or the dye from dialkylamine and Meldola blue (nitrosodimethylaniline and ß-naphthol, see S chu 1 tz no. 65 1) in zapon varnish result in completely lightfast colorations. Example 1 g of 2-dimethylamino-2'-diethylamino-3'-methyloxazine chloride are dissolved in 25 g of Zapon varnish with gentle heating.
