  Verfahren zur Herstellung von Farblacken. 
 EMI1.1 
 in ausgezeichneter Weise zur Herstellung von Lackfarben (Pigmentfarben) eignen. Die aus diesen Farbstoffen z. B. durch Fällen mit Baryt und Tonerde erhältlichen Lacke zeichnen sich durch   grosse   Lebhaftigkeit und grosses Feuer aus. Sie kommen an Schönheit den aus Eosinen erhältlichen Bleilacken sehr nahe. Das vorliegende Verfahren   ermöglicht   daher auf einem neuen Wege zu bleifreien, den Eosinlacken ähnlichen Lacken zu gelangen. Dieses Ergebnis war überraschend, da sowohl einerseits die entsprechenden Farbstoffe aus den   nichtazidylierten   Periaminonaphtol- 
 EMI1.2 
 bedeutend weniger lebhafte und stumpfere Lacke liefern. 



   Beispiel. 
 EMI1.3 
 von Tonerdehydrat mit Wasser hergestellt ist. Die so erhaltene Mischung wird mit   einer 5% igen   Chlorbaryumlösung bis zur   Beendigung   der Ausfällung des Farbstoffs versetzt. Der Niederschlag wird darauf filtriert, ausgewaschen, getrocknet und der Lack in üblicher Weise fertig   gemacht.   
 EMI1.4 
   naphtol-3. 6-disulfosäure   erhaltene ein Blaurot, der in derselben Weise   aus c-Sulfanilsäure her-   gestellte Farbstoff ein feuriges Rot, derjenige aus diazotierter   o-Sulfanilsäure   und 1.   8-Azetyl-   aminonaphtol-3,6-disulfosäure in alkalischer Lösung dargestellte, ein lebhaftes Rot.

   Der durch Kuppeln von diazotierter 1.3. 8-Naphtylamindisulfosäure in alkalischer Lösung mit 1.   8-Benzoyl-     aminonaphtol-4.   6-disulfosäure gewonnene Farbstoff liefert ein schönes Blaurot usw. 
 EMI1.5 
 tiertes Aminoazobenzol oder   dgl.,   so erhält man Lacke von   blaueren Nuancen. So   liefert z. B. der durch Kuppeln in alkalischer Lösung gewonnene Farbstoff aus diazotierter Aminoazobenzol-   disulfosäure   und 1. 8-Benzoylaminonaphtol-3.6-disulfosäure einen blauvioletten Tonerdebarytlack.

  Process for the production of colored lakes.
 EMI1.1
 excellently suited for the production of lacquer paints (pigment paints). The from these dyes z. For example, lacquers obtainable by felling with barite and clay are characterized by great liveliness and great fire. In terms of beauty, they come very close to the lead paints available from eosins. The present process therefore makes it possible to achieve lead-free paints similar to eosin paints in a new way. This result was surprising because on the one hand the corresponding dyes from the non-acidylated periaminonaphthol
 EMI1.2
 deliver significantly less lively and duller paints.



   Example.
 EMI1.3
 is made of alumina hydrate 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 out, dried and the paint is made ready in the usual way.
 EMI1.4
   naphtol-3. 6-disulfonic acid obtained a blue red, the dye made in the same way from c-sulfanilic acid a fiery red, that made from diazotized o-sulfanilic acid and 1,8-acetylaminonaphthol-3,6-disulfonic acid in alkaline solution, a vivid one Red.

   The by coupling of diazotized 1.3. 8-naphthylamine disulfonic acid in alkaline solution with 1. 8-benzoylaminonaphthol-4. Dye obtained from 6-disulfonic acid produces a beautiful blue-red etc.
 EMI1.5
 Aided aminoazobenzene or the like. Lacquers with bluer shades are obtained. For example, B. the dye obtained by coupling in an alkaline solution from diazotized aminoazobenzene disulfonic acid and 1. 8-benzoylaminonaphthol-3,6-disulfonic acid a blue-violet alumina lacquer.



   Any other method can also be used instead of the method described in the example
