  Verfahren zur Darstellung von lichtechten Farblacken. 



   Es wurde gefunden, dass die aus diazotiertem p-Aminobenzophenon und der   2-Naphtol-   -6-monosulfosäure oder 2-Naphtol-3.6-disulfosäure entstehenden   Farbstoffe b :ch vorzüglich   zur Herstellung von Lacken eignen. 



   Beide Farbstoffe zeigen sehr gute Fällbarkeit. Der   schwerlösliche   und deshalb in Teigform verwendete Farbstoff aus 2-Naphtol-6-monosulfonsäure bildet bei seiner Fällung als Kalk-oder Barytlack ein lebhaftes Orange, während aus dem leichter   löslichen   Farbstoff aus der 2-Naphtol-3.6-disulfosäure ein sehr klarer, blauroter Lack entsteht. Beide vereinigen eine hervorragende Lichtechtheit mit guter   Wasserechtheit. 0   
Beispiel. 



   100 Teile Schwerspat werden in eine Auflösung von 20 Teilen schwefelsaurer Tonerde in 1200 Teilen heissen Wassers eingerührt. Hiezu gibt man die kochende   Auflösung   von 6   Teiler,   des Farbstoffes aus diazotiertem p-Aminobenzophenon und 2-Naphtol-3.6-disulfo-   aäurH   und 10 Teilen kalzinierter Soda in   1000 Teilen Wasser,   bringt das Ganze wieder   zum Kochen und   setzt dann die heisse Lösung von 30 Teilen kristallisierten Chlorbariums 
 EMI1.1 
 tiltriert und ausgewaschen. Der Lack zeigt ein blaustichiges Rot. 



   Die Fällung des Farbstoffes aus diazotiertem p-Aminobenzophenon und 2-Naphtol- -6-sulfosäure geschieht in derselben Weise. Zur vollkommenen Umsetzung des schwer-   löslichen   Farbstoffes ist nur   zum     Schluss längerps   Aufkochen notwendig.

  Process for the representation of lightfast colored lacquers.



   It has been found that the diazotized p-aminobenzophenone and 2-naphthol-6-monosulfonic acid or 2-naphthol-3,6-disulfonic acid are particularly suitable for the production of paints.



   Both dyes show very good precipitability. The sparingly soluble and therefore used in dough form dye from 2-naphthol-6-monosulfonic acid forms a vivid orange when precipitated as a lime or barite varnish, while the more easily soluble dye from 2-naphthol-3,6-disulphonic acid forms a very clear, blue-red varnish arises. Both combine excellent lightfastness with good waterfastness. 0
Example.



   100 parts of barite are stirred into a solution of 20 parts of alumina sulfuric acid in 1200 parts of hot water. To this you add the boiling solution of 6 parts of the dye of diazotized p-aminobenzophenone and 2-naphthol-3,6-disulfo-acid and 10 parts of calcined soda in 1000 parts of water, bring the whole thing back to the boil and then add the hot solution 30 parts of crystallized chlorobarium
 EMI1.1
 filtered and washed out. The paint shows a bluish red.



   The dye is precipitated from diazotized p-aminobenzophenone and 2-naphthol-6-sulfonic acid in the same way. For complete implementation of the sparingly soluble dye, it is only necessary to boil for longer at the end.
