Während die Azofarbstoffe aus Aminoazobenzoldisulfosäüre und Naphtolsulfosäuren sehr lichtechte Lacke geben, sind aus den entsprechenden Kombinationen des Aminoazobenzols und der Aminoazobenzolmonosulfosäure seither Farblacke von nur geringer Lichtechtheit hergestellt worden, wie dies in der Patentschrift 154533 näher ausgeführt worden ist.While the azo dyes from Aminoazobenzoldisulfosäüre and naphthol sulfonic acids give very lightfast lacquers, are made from the corresponding combinations of aminoazobenzene and the aminoazobenzene monosulfonic acid since then, color lakes of only poor lightfastness has been produced, as has been explained in more detail in patent specification 154533 is.
Es hat sich nun gezeigt, daß die Angaben dieser Patentschrift in solcher Allgemeinheit nicht zutreffen, daß vielmehr die speziellen. Kombinationen aus Aminoazobenzol und Aminoazotoluol einerseits und i-Naphtol-4-sulfosäure andrerseits Farblacke von hervorragender Lichtechtheit liefern. Diese Farblacke sind sogar denjenigen aus Aminoazobenzoldisulfosäure -)- 1 ^-Naphtolsulfosäure an Lichtechtheit bei weitern überlegen, was sich in keiner Weise voraussehen ließ.It has now been shown that the information in this patent specification in such generality does not apply that rather the special. Combinations of aminoazobenzene and aminoazotoluene on the one hand and i-naphthol-4-sulfonic acid on the other hand color lakes of excellent quality Deliver lightfastness. These lake lakes are even those made from aminoazobenzene disulfonic acid -) - 1 ^ -Naphtholsulfonic acid in terms of lightfastness by far, what could not be foreseen in any way.
5 Teile des in üblicher Weise aus der Diazoverbindung des Aminoazobenzols oder Aminoazotoluols mit i-Naphtol-4-sulfosäure erzeugten Farbstoffs werden in wäßriger Lösung oder wäßriger Suspension in eine Tonerdehydratpaste eingerührt, welche aus den wäßrigen Lösungen von 10 Teilen schwefelsaurer Tonerde und 5 Teilen Soda bereitet wurde. Das so erhaltene Gemisch wird hierauf mit etwa 17 Teilen Chlorbarium in ioprozentiger Lösung kalt oder warm gefällt. 5 parts of the in the usual way from the diazo compound of aminoazobenzene or Aminoazotoluene with i-naphthol-4-sulfonic acid Dye produced are in aqueous solution or aqueous suspension in an alumina hydrate paste stirred in, which from the aqueous solutions of 10 parts of sulfuric acid Clay and 5 parts soda was prepared. The mixture obtained in this way is then added to about 17 parts of chlorobarium in 10 percent solution cold or warm.
Der Niederschlag wird abfiltriert, eventuell ausgewaschen und getrocknet oder als Paste verwendet.The precipitate is filtered off, possibly washed out and dried or as a paste used.
Das beschriebene Verfahren kann auch durch die anderen in der Lackfabrikation üblichen Verfahren ersetzt werden, wobei auch Zusätze, wie Türkischrotöl, Glyzerin usw., Mitverwendung finden können. Selbstverständlich kann auch die Herstellung der Farbstoffe gleichzeitig mit der Erzeugung der Lacke erfolgen.The method described can also be carried out using the other methods commonly used in paint production Processes are replaced, with additives such as Turkish red oil, glycerine, etc., also being used can find. The production of the dyes can of course also be carried out at the same time take place with the production of the paints.
