Description

Verfahren zur Herstellung von Farblacken Es wurde gefunden, daß man Farblacke von wertvollen Eigenschaften erhält, wenn man die Kondensationsprodukte aus aromatischen, Nitro-oder Chinongruppen und Halogen enthaltenden Verbindungen und aromatischen Aminen, die auch beliebige Substituenten, z. B. Sulfo-, Carboxyl-, Hydroxylgruppen usw., enthalten können, verlackt. Die genannten Kondensationsprodukte können, soweit sie salzbildende Gruppen besitzen, in Form der freien Säuren oder ihrer Salze verwendet werden.Process for the preparation of colored lakes It has been found that one Color lakes of valuable properties are obtained by using the condensation products from aromatic, nitro or quinone groups and halogen-containing compounds and aromatic amines which can also contain any substituents, e.g. B. sulfo-, carboxyl, Hydroxyl groups, etc., may contain laked. The condensation products mentioned can, as far as they have salt-forming groups, in the form of the free acids or their salts are used.

Die auf die beanspruchte Weise aus den leicht darstellbaren Kondensationsprodukten von aromatischen, Nitro- oder Chinongruppen und Halogen enthaltenden Verbindungen mit aromatischen Aminen erhältlichen Farblacke zeichnen sich durch wertvolle färberische Eigenschaften aus; so ist ihre Wasser-, Überdruck-und Lichtechtheit ganz hervorragend. Beispiel i q. Teile des Natriumsalzes des Kondensationsproduktes aus 2 - q.-Dinitrochlorbenzol und Anthranilsäure werden unter Zusatz von 5 Teilen calcinierter Soda in 5oo Teilen Wasser gelöst; zu dieser Lösung gibt man 2o Teile Schwerspat und io Teile schwefelsaure Tonerde (mit 18 °/o A12 03-Gehalt),-=i : io in Wasser gelöst, und fällt bei etwa 7o' mit 16 Teilen Chlorbaryum, i : io gelöst, aus. Der Farblack wird wie üblich fertiggestellt. Der so hergestellte Farblack ist orangerot gefärbt und besitzt hohe Licht-, Wasser- und Überdruckechtheit; gleich wertvolle, aber mehr orangegelbe Farbtöne erhält man unter Verwendung geringerer Alkalimengen, als oben angegeben.That in the claimed manner from the easily representable condensation products of aromatic, nitro or quinone groups and halogen-containing compounds Color lakes obtainable with aromatic amines are characterized by valuable coloring properties Properties from; so their water, pressure and light fastness is quite excellent. Example i q. Parts of the sodium salt of the condensation product from 2 - q.-dinitrochlorobenzene and anthranilic acid with the addition of 5 parts of calcined soda in 500 parts Dissolved water; 20 parts of barite and 10 parts of sulfuric acid are added to this solution Alumina (with 18% A12 03 content), - = i: io dissolved in water, and falls at about 7o 'with 16 parts of chlorobaryum, i: io dissolved, from. The color varnish will be as usual completed. The colored varnish produced in this way is colored orange-red and has high Fastness to light, water and overprinting; equally valuable, but more orange-yellow shades is obtained using lower amounts of alkali than indicated above.

Beispiel 2 2o Teile Schwerspat werden mit der Lösung von io Teilen schwefelsaurer Tonerde (mit 18 A12 03 -Gehalt) in ioo Teilen Wasser angeteigt, hierauf fügt man q. Teile des Natriumsalzes des Kondensationsproduktes aus 2 - 4.-Dinitrochlorbenzol und Sulfanilsäure, gelöst in 5oo Teilen Wasser, zu und ferner 16 Teile Chlorbaryum, i : io in Wasser gelöst, und 3,5 Teile calcinierte Soda, i : io gelöst.Example 2 20 parts of heavy spar are mixed with the solution of 10 parts Sulfuric alumina (with 18 A12 03 content) made into a paste in 100 parts of water, then put into a paste one adds q. Parts of the sodium salt of the condensation product from 2-4 dinitrochlorobenzene and sulfanilic acid, dissolved in 500 parts of water, to and also 16 parts of chlorobaryum, i: io dissolved in water, and 3.5 parts of calcined soda, i: io dissolved.

Der so hergestellte Farblack zeigt eine grünlichgelbe Nuance und besitzt hohe Licht-, Wasser- und Überdruckechtheit.The colored varnish produced in this way shows a greenish-yellow shade and possesses high light, water and overprint fastness.

An Stelle der in den Beispielen genannten Salze können auch die freien Säuren Verwendung finden.Instead of the salts mentioned in the examples, the free salts can also be used Acids are used.
