KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Über die Verwendbarkeit von Monoazofarbstoffen aus «-Naphtholsulfosäuren für die Darstellung von Farblacken lagen bisher noch keine Literaturangaben vor. Da fast sämtliehe in letzter Zeit bekannt gewordenen Patente für die Darstellung von Farblacken die Verwendung von β - Naphtholfarbstoffen und nur einige wenige diejenige von Farbstoffen aus Sulfosäuren des ß-Naphthols vorschreiben,About the usability of monoazo dyes from «-naphtholsulfonic acids for the Representation of colored lacquers were not yet available in the literature. Almost all of them Recently known patents for the representation of colored lacquers Use of β-naphthol dyes and only a few that of dyes prescribe from sulfonic acids of ß-naphthol,
ίο nicht dagegen diejenige von Farbstoffen aus «-Naphtholsulfosäuren, so war man offenbar der Ansicht, daß nur die ß-Naphtholfarbstoffe zur Bildung brauchbarer Farblacke geeignet wären. Es wurde nun die Beobachtung gemacht, daß der Monoazofarbstoff aus o-Diazobenzoesäure und i-Naphthol-ß^o-disulfosäure sich sehr gut für die Lackfarbenfabrikation eignet, indem derselbe Farblacke von großer Lichtechtheit liefert. Die so erhaltenen Farblacke sind z. B. erheblich lichtechter wie die entsprechenden, in der Patentschrift 141257 beschriebenen Lacke des Farbstoffes aus diazotierter o-Amidobenzoesäure und 2-Naphthol - 3 · 6 - disulfosäure.ίο not on the other hand that of dyes «-Naphthol sulfonic acids, it was evidently of the opinion that only the ß-naphthol dyes would be suitable for the formation of useful color lakes. The observation has now been made that the monoazo dye from o-diazobenzoic acid and i-naphthol-ß ^ o-disulfonic acid is very well suited for lacquer paint production by adding the same color lacquers of great Provides lightfastness. The color lakes thus obtained are z. B. considerably more lightfast than that corresponding, in the patent 141257 described varnishes of the dye from diazotized o-amidobenzoic acid and 2-naphthol - 3 · 6 - disulfonic acid.
6 Teile des in üblicher Weise durch Kuppeln der Diazoverbindung der o-Amidobenzoesäure mit i-Naphthol-3'6-disulfosäure dargestellten Farbstoffes werden in 500 Teilen Wasser gelöst. Diese Lösung läßt man darauf unter gutem Umrühren in eine Mischung einfließen, die durch sorgfältiges Anschlemmen von 10 Teilen einer ioprozentigen Paste von Tonerdehydrat mit Wasser hergestellt ist. Das so erhaltene Gemisch wird mit einer 5prozentigen Chlorbariumlösung bis zur Beendigung der Ausfällung des Farbstoffes versetzt. Der Niederschlag wird darauf filtriert, ausgewaschen und getrocknet und der Lack in üblicher Weise fertig gemacht. Derselbe zeigt · eine lebhafte rote Nuance.6 parts of the in the usual way by coupling the diazo compound of o-amidobenzoic acid with i-naphthol-3'6-disulfonic acid prepared dye are dissolved in 500 parts of water. This solution is then allowed to flow into a mixture with thorough stirring 10 parts of an 10 percent paste of alumina hydrate is made with water. The mixture obtained in this way is with a 5 percent strength Chlorbarium solution added until the precipitation of the dye has ended. The precipitate is then filtered and washed out and dried and the paint finished in the usual way. It shows a vivid red shade.
Man kann an Stelle des im Beispiel beschriebenen Verfahrens auch irgend eine andere der in der Pigmentfarbenfabrikation übliehen Lackbildungsmethoden anwenden.Any other method can be used instead of the method described in the example apply the lacquer formation methods customary in pigment paint production.
