Description

Verfahren zur Herstellung lichtechter Farblacke Es ist_bekannt, daß man wertvolle Farblacke erhält, wenn man basische Farbstoffe, die auch saure Gruppen enthalten können, mit komplexen Säuren, die man aus Verbindungen von Wolfram oder Molybdän oder beiden durch Behandlung mit nicht reduzierenden Verbindungen des Phosphors, der Kieselsäure, des Bors, Aluminiums,:Chroms, Eisens, Mangans, Arsens, Antimons usw. erhalten kann, behandelt.Process for the production of lightfast colored lacquers It is known that you get valuable color lakes if you have basic dyes, which also have acidic groups may contain complex acids obtained from compounds of tungsten or Molybdenum or both by treatment with non-reducing compounds of phosphorus, of silica, boron, aluminum,: chromium, iron, manganese, arsenic, antimony etc. can get treated.

Es wurde nun gefunden, daß man zu Farblacken von besonders wertvollen Eigenschaften gelangt, wenn man auf basische Farbstoffe, die auch saure Gruppen enthalten können, Wolfram oder Molybdän oder beide enthaltende komplexe Verbindungen, die während oder nach ihrer Herstellung mit reduzierend wirkenden Mitteln behandelt sind, oder deren Wolfram oder Molybdän enthaltende Komponenten vor der Herstellung mit reduzierenden Mitteln behandelt wurden, einwirken läßt.It has now been found that color lakes of particularly valuable Properties obtained when one uses basic dyes that also contain acidic groups may contain tungsten or molybdenum or complex compounds containing both, which are treated with reducing agents during or after their production or their tungsten or molybdenum-containing components prior to manufacture have been treated with reducing agents.

In der nicht vorveröffentlichten Patentschrift 515 032 ist ein Verfahren zum Fixieren von Farbstoffen auf Faserstoffen beschrieben, bei dem komplexe Verbindungen von Wolfram- oder Molybdänsäure oder Gemische beider auf der Faser vor dem Färben mit Reduktionsmitteln behandelt werden, worauf die Faser mit basischen Farbstoffen gefärbt wird. Hiervon unterscheidet sich das vorliegende Verfahren dadurch, daß hier Farblacke als solche hergestellt werden. Zur Durchführung des beanspruchten Verfahrens geeignete Wolfram und Molybdän enthaltende Verbindungen können beispielsweise nach ,dem Verfahren des älteren Patents 539 174 hergestellt werden.In the unpublished patent specification 515 032 a process for fixing dyes on fiber materials is described in which complex compounds of tungsten or molybdic acid or mixtures of both on the fiber are treated with reducing agents before dyeing, whereupon the fiber is dyed with basic dyes. The present process differs from this in that color lakes are produced as such. Compounds containing tungsten and molybdenum suitable for carrying out the claimed process can be produced, for example, according to the process of the earlier patent 539,174.

Beispiel Man behandelt die Lösung eines basischen Farbstoffes mit einer Lösung einer reduzierenden Phosphor-Wolfram-Molybdän-Verbindung. Es entsteht ein äußerst lichtechter Farblack.Example The solution of a basic dye is treated with a solution of a reducing phosphorus-tungsten-molybdenum compound. It arises an extremely lightfast colored lacquer.

PATENTANSPRUCH: Verfahren zur Herstellung lichtechter Farblacke durch Einwirkung von Wolfram oder Molybdän oder beide enthaltenden komplexen Verbindungen auf basische Farbstoffe, welche auch saure Gruppen enthalten können, dadurch gekennzeichnet, daB Wolfram oder Molybdän oder beide enthaltende komplexe Verbindungen, die während oder mach ihrer Herstellung mit reduzierend wirkenden Mitteln behandelt sind, oder deren Wolfram oder Molybdän enthaltende Komponenten vor der Herstellung der Komplexverbindungen mit reduzierenden Mitteln behandelt wurden, zur Einwirkung gelangen. PATENT CLAIM: Process for the production of lightfast colored lacquers by the action of tungsten or molybdenum or both containing complex compounds on basic dyes, which can also contain acidic groups, characterized in that tungsten or molybdenum or both containing complex compounds, which during or after their production with reducing active agents are treated, or the tungsten or molybdenum-containing components were treated with reducing agents before the production of the complex compounds, come into action.
