Definitions
- Optical brighteners are often used as mixtures of two or more different types because such mixtures have a synergistic effect in that the degree of whiteness of the mixture is higher than the degree of whiteness of the same amount of the individual components.
- the invention therefore relates to mixtures of optical brighteners composed of 5 to 45 parts by weight of the compound of the formula I. and 95 to 55 parts by weight of one of the compounds of formulas 2 and 3
- the mixtures of optical brighteners according to the invention preferably consist of the compounds of the formulas 1 and 2.
- the mixtures according to the invention are obtained by mixing the compound of the formula 1 with one of the two compounds of the formulas 2 and 3 in the stated mixing ratio.
- the preferred mixing ratio of components 1 and 2 or 1 and 3 is 10 to 40 to 90 to 60 parts by weight, in particular 10 to 30 to 90 to 70 parts by weight, and for components 1 and 2 preferably 15 to 25 to 85 to 75 parts by weight.
- the present invention furthermore relates to the use of mixtures of the compound of the formula 1 and one of the two compounds of the formulas 2 and 3 for the optical brightening of textile material containing polyester fibers and polyester fibers, and agents for the optical brightening of textile materials containing mixtures of polyester fibers and polyester fibers the compound of formula 1 and one of the two compounds of formulas 2 and 3.
- the mixtures according to the invention are particularly suitable for optically brightening textile materials made of linear or modified polyesters. They can be applied to the textile material by known methods, for example by the exhaust process at 90 to 140 ° C or by the pad thermal process at 160 to 220 ° C.

Description
Optische Aufheller werden oft als Mischungen von zwei oder mehreren verschiedenen Typen verwendet, weil solche Mischungen einen synergistischen Effekt zeigen, indem der Weissgrad der Mischung höher ist als der Weissgrad der gleichen Menge der jeweiligen Einzelkomponenten.Optical brighteners are often used as mixtures of two or more different types because such mixtures have a synergistic effect in that the degree of whiteness of the mixture is higher than the degree of whiteness of the same amount of the individual components.
So ist aus der DE-A-2 602 750 bekannt, dass Mischungen aus blaustichig fluoreszierenden optischen Aufhellern aus 4,4′-Divinylstilbenen mit nicht wasserlöslich machenden elektronenanziehenden Substituenten und rotstichigen Aufhellern der Naphthalimid- oder Bisbenzoxazolylethylenreihe sehr brillante Aufhelleffekte mit hohem Maximalweiss zeigen. Die mit konkreten Gemischen erzielten Weissgrade sind jedoch unbefriedigend.For example, it is known from DE-A-2 602 750 that mixtures of bluish fluorescent optical brighteners made of 4,4′-divinylstilbenes with non-water-solubilizing electron-attracting substituents and red-tinged brighteners from the naphthalimide or bisbenzoxoxolylethylene series show very brilliant brightening effects with high maximum white. However, the degrees of whiteness achieved with specific mixtures are unsatisfactory.
Es wurde nun gefunden, dass man eine deutliche Erhöhung des Weissgrades erhält, wenn man 4,4′-Bis-(cyanvinyl)-stilbenverbindungen (DE-A 26 02 750) mit einem anderen bekannten Aufheller der unten angegebenen Struktur mischt.It has now been found that a significant increase in the degree of whiteness is obtained if 4,4′-bis (cyanovinyl) stilbene compounds (DE-A 26 02 750) are mixed with another known brightener of the structure given below.
Gegenstand der Erfindung sind daher Mischungen von optischen Aufhellern aus 5 bis 45 Gewichtsteilen der Verbindung der Formel I
und 95 bis 55 Gewichtsteilen einer der Verbindungen der Formeln 2 und 3
and 95 to 55 parts by weight of one of the compounds of formulas 2 and 3
Vorzugsweise bestehen die erfindungsgemässen Mischungen optischer Aufheller aus den Verbindungen der Formeln 1 und 2.The mixtures of optical brighteners according to the invention preferably consist of the compounds of the formulas 1 and 2.
Die erfindungsgemässen Mischungen erhält man durch Mischen der Verbindung der Formel 1 mit einer der beiden Verbindungen der Formeln 2 und 3 im angegebenen Mischungsverhältnis. Das bevorzugte Mischungsverhältnis der Komponenten 1 und 2 bzw. 1 und 3 beträgt 10 bis 40 zu 90 bis 60 Gewichtsteile, insbesondere 10 bis 30 zu 90 bis 70 Gewichtsteile, und für die Komponenten 1 und 2 vorzugsweise 15 bis 25 zu 85 bis 75 Gewichtsteile.The mixtures according to the invention are obtained by mixing the compound of the formula 1 with one of the two compounds of the formulas 2 and 3 in the stated mixing ratio. The preferred mixing ratio of components 1 and 2 or 1 and 3 is 10 to 40 to 90 to 60 parts by weight, in particular 10 to 30 to 90 to 70 parts by weight, and for components 1 and 2 preferably 15 to 25 to 85 to 75 parts by weight.
Weitere Gegenstände der vorliegenden Erfindung sind die Verwendung von Mischungen aus der Verbindung der Formel 1 und einer der beiden Verbindungen der Formeln 2 und 3 zum optischen Aufhellen von Polyesterfasern und Polyesterfasern enthaltendem Textilmaterial, sowie Mittel zum optischen Aufhellen von Polyesterfasern und Polyesterfasern enthaltendem Textilmaterial enthaltend Mischungen aus der Verbindung der Formel 1 und einer der beiden Verbindungen der Formeln 2 und 3.The present invention furthermore relates to the use of mixtures of the compound of the formula 1 and one of the two compounds of the formulas 2 and 3 for the optical brightening of textile material containing polyester fibers and polyester fibers, and agents for the optical brightening of textile materials containing mixtures of polyester fibers and polyester fibers the compound of formula 1 and one of the two compounds of formulas 2 and 3.
Die erfindungsgemässen Mischungen eignen sich besonders zum optischen Aufhellen von Textilmaterialien aus linearen oder modifizierten Polyestern. Sie können nach bekannten Methoden auf das Textilgut appliziert werden, beispielsweise nach dem Ausziehverfahren bei 90 bis 140°C oder nach dem Foulardthermverfahren bei 160 bis 220°C.The mixtures according to the invention are particularly suitable for optically brightening textile materials made of linear or modified polyesters. They can be applied to the textile material by known methods, for example by the exhaust process at 90 to 140 ° C or by the pad thermal process at 160 to 220 ° C.
Die erfindungsgemässen Mischungen zeichnen sich durch sehr gutes färberisches Verhalten aus. Ausser durch einen höheren Weissgrad gegenüber den entsprechenden Steilen der jeweiligen Einzelkomponenten welsen die Mischungen eine verbesserte Brillanz der Aufhellungen und eine gute Lichtechtheit auf.The mixtures according to the invention are distinguished by very good dyeing behavior. In addition to a higher degree of whiteness compared to the corresponding parts of the individual components, the mixtures catalyze an improved brilliance of the brightening and good light fastness.
