Verfahren zur Herstellung von lichtechten Farblacken.
Über die Verwendbarkeit von Monozaofarbstoffen aus α-Naphtolsulfosäuren für die Darstellung von Farbtacken lagen bisher noch keine Literaturangaben vor. Da fast sämtliche in letzter Zeit, bekannt gewordenen Patente für die Darstellung von Farblacken die Verwendung von ss-Naphtolfarbstoffen und nur einige wenige diejenige von Farbstoffen aus Sulfosiiuren des -Naphtols vorschreiben, nicht dagegen diejenige von Farbstoffen aus α-Naphtol- sulfosäuren, so war man offehbar der Ansicht, dass nur die ss-Naphtolfarbstoffe zur Bildung brauchbarer Farhlaclw geeignet wären.
Es wurde nun die Beobachtung gemacht, dass der Monoazofarbstoff aus o-Diazobenzoesäure und 1-Naphtol-3-6-disulfosäure sich schr gut für die Lackfarbonfabrikation eignet, indem derselbe Farblacke von grosser Lichtechtheit liefert.
Die 80 erhaltenen Farblacke sind z. B. erheblich lichtechter wie die entsprechenden in der deutschen Patentschrift Nr. 141257 beschriebenen Lacke des Farbstoffes aus diazotierter o-Amidobenzoesäureund2-Naphtol-3-6-disulfosäure.
EMI1.1
Pate von Tonerdohydrat mit Wasser hergostollt ist. Das so erhaltene Gemisch wird mit einer 5%igen Chlorbaryumlösung 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.
Man kann selbstverständlich an Stelle des im Beispiel beschriebenen Verfahrens auch irgendeine andere der in der Pigmentfarbenfabrikation üblichen Lackbildungsmethoden anwenden.

Process for the production of lightfast colored lacquers.
As yet, no literature has been published on the use of monozao dyes made from α-naphthol sulfonic acids for the representation of color spots. Since almost all of the recently known patents for the preparation of color lakes prescribe the use of β-naphthol dyes and only a few that of dyes from sulfosyl acids of -naphtol, but not that of dyes from α-naphthol-sulfonic acids one evidently of the opinion that only the s-naphthol dyes would be suitable for the formation of useful colors.
The observation has now been made that the monoazo dye made from o-diazobenzoic acid and 1-naphthol-3-6-disulfonic acid is extremely suitable for the manufacture of varnish dyes, in that the same varnish gives high lightfastness.
The 80 colored lakes obtained are z. B. considerably more lightfast than the corresponding lacquers of the dye from diazotized o-amidobenzoic acid and 2-naphthol-3-6-disulfonic acid described in German Patent No. 141257.
EMI1.1
Pate of alumina hydrate is hergostollt with water. A 5% chlorobaryum solution is added to the mixture obtained in this way until the dyestuff has precipitated out. The precipitate is then filtered, washed and dried and the paint is made ready in the usual way. It shows a vivid red shade.
Instead of the method described in the example, any other of the lacquer formation methods customary in pigment paint manufacture can of course be used.
