Abstract
Description
Die vorliegende Erfindung betrifft organische Kupferkomplexe auf Basis von Bisazomethinen, die bei der Färbung von Textilien, insbesondere von ungefärbtem Polyamid, als Lichtstabilisatoren dem Färbebad zugesetzt werden und dabei viel weniger Kupfer im Färbeabwasser zurücklassen als bisher verwendete Substanzen.The present invention relates to organic copper complexes based on bisazomethines, which the dyeing of textiles, in particular undyed polyamide, as light stabilizers Be dyed bath and leave much less copper in the dyeing waste water than before used substances.
Die Verwendung von Kupfersalzen zur Verbesserung der Lichtechtheit von Textilien ist seit langem bekannt. So wird beispielsweise in EP 0 245 204 A1 ein Verfahren zur fotochemischen Stabilisierung von ungefärbtem und gefärbtem Polyamidfasermaterial oder dessen Mischungen mit anderen Fasermaterialien offenbart, wobei das Fasermaterial mit einer Mischung aus einem organischen Kupferkomplex, einem Lichtschutzmittel und gegebenenfalls einem Antioxidans behandelt wird.The use of copper salts to improve the light fastness of textiles has long been known. For example, EP 0 245 204 A1 discloses a process for photochemical stabilization of undyed and dyed polyamide fiber material or mixtures thereof with others Fiber materials disclosed, wherein the fiber material with a mixture of an organic Copper complex, a light stabilizer and optionally an antioxidant is treated.
Die bisher bekannten und auch in EP 0 245 204 A1 verwendeten organischen Kupferkomplexe weisen jedoch den gravierenden technischen Nachteil auf, dass in den Färbebädern zuviel Kupfer verbleibt und somit das Abwasser belastet wird. Folglich besteht immer noch ein Bedarf an umweltverträglicheren Lichtstabilisatoren für Textilien.The organic copper complexes known to date and also used in EP 0 245 204 A1 have However, the serious technical disadvantage that in the dyebaths too much copper remains and thus the wastewater is loaded. Consequently, there is still a need for more environmentally friendly Light stabilizers for textiles.
Überraschenderweise wurde nun gefunden, dass gewisse, zu den oben erwähnten Verbindungen strukturähnliche Kupferkomplexe, die beim Färben von Textilien als Lichtstabilisatoren zugesetzt werden, eine deutlich geringere Menge an Kupfer im Färbebad hinterlassen und somit vom ökologischen Gesichtspunkt her viel umweltverträglicher sind.Surprisingly, it has now been found that certain of the above-mentioned compounds structurally similar copper complexes added as dye stabilizers in the dyeing of textiles be left a significantly lower amount of copper in the dyebath and thus of the ecologically more environmentally friendly.
