Description

N-Benzyl-m-phenylendiamin-Derivate und diese Verbindungen enthaltende FärbemittelN-benzyl-m-phenylenediamine derivatives and colorants containing these compounds
Die Erfindung betriff neue N-Benzyl-m-phenylendiamin-Derivate sowie diese Verbindungen enthaltende Mittel zum Färben von Keratinfasern.The invention relates to new N-benzyl-m-phenylenediamine derivatives and agents containing these compounds for dyeing keratin fibers.
Auf dem Gebiet der Färbung von Keratinfasern, insbesondere der Haarfärbung, haben Oxidationsfarbstoffe eine wesentliche Bedeutung erlangt. Die Färbung entsteht hierbei durch Reaktion bestimmter Entwicklersubstanzen mit bestimmten Kupplersubstanzen in Gegenwart eines geeigneten Oxidationsmittels. Als Entwicklersubstanzen werden hierbei insbesondere 2,5-Diaminotoluol, 2-(2,5-Diaminophenyl)- ethylalkohol, 1-(2,5-Diaminophenyl)-ethylalkohol, p-Aminophenol, 1 ,4-Diaminobenzol und 4,5-Diamino-1-(2-hydroxyethyl)-pyrazol eingesetzt, während als Kupplersubstanzen beispielsweise Resorcin, 2-Methylresorcin, 1-Naphthol, 3-Aminophenol, 2-Amino-4-(2'-hydroxy- ethyl)amino-anisol, 1 ,3-Diamino-4-(2'-hydroxyethoxy)benzol und 2,4-Diamino-5-fluor-toluol zu nennen sind.Oxidation dyes have become very important in the field of coloring keratin fibers, in particular hair coloring. The coloration arises from the reaction of certain developer substances with certain coupler substances in the presence of a suitable oxidizing agent. In particular, 2,5-diaminotoluene, 2- (2,5-diaminophenyl) ethyl alcohol, 1- (2,5-diaminophenyl) ethyl alcohol, p-aminophenol, 1, 4-diaminobenzene and 4,5-diamino are used as developer substances -1- (2-hydroxyethyl) pyrazole, and suitable couplers are, for example, resorcinol, 2-methylresorcinol, 1-naphthol, 3-aminophenol, 2-amino-4- (2 '-hydroxy-ethyl) amino-anisole, 1, 3-Diamino-4- (2 ' -hydroxyethoxy) benzene and 2,4-diamino-5-fluorotoluene are mentioned.
An Oxidationsfarbstoffe, die zur Färbung menschlicher Haare verwendet werden, werden neben der Färbung in der gewünschten Intensität zahlreiche zusätzliche Anforderungen gestellt. So müssen die Farbstoffe in toxikologischer und dermatologischer Hinsicht unbedenklich sein und die erzielten Haarfärbungen eine gute Lichtechtheit, Dauerwellechtheit, Säureechtheit und Reibeechtheit aufweisen. Auf jeden Fall aber müssen solche Färbungen ohne Einwirkung von Licht, Reibung und chemischen Mitteln über einen Zeitraum von mindestens 4 bis 6 Wochen stabil bleiben. Außerdem ist es erforderlich, daß durch Kombination geeigneter Entwicklersubstanzen und Kupplersubstanzen eine breite Palette verschiedener Farbnuancen erzeugt werden kann.Oxidation dyes, which are used to dye human hair, are subject to numerous additional requirements in addition to dyeing in the desired intensity. For example, the dyes have to be harmless from a toxicological and dermatological point of view and the hair colorations obtained have good lightfastness, permanent wave fastness, acid fastness and rubbing fastness. Definitely have to such stains remain stable for at least 4 to 6 weeks without the influence of light, friction and chemical agents. It is also necessary that a wide range of different color shades can be produced by combining suitable developer substances and coupler substances.
Es wurde bereits versucht, die Eigenschaften von m-Phenyldiaminen durch die Einführung von Substituenten zu verbessern. In diesem Zusammenhang sei auf die DE-OS 29 34 330 verwiesen, in der unter anderem auch Färbemittel beschrieben, welche als Kupplersubstanzen spezielle, N- substituierte m-Phenylendiamine enthalten. Mit den derzeit bekannten Färbemitteln ist es jedoch nicht möglich, die an ein Färbemittel gestellten Anforderungen in allen Punkten zu erfüllen. Es bestand daher weiterhin ein Bedürfnis nach neuen Entwicklersubstanzen, welche die vorgenannten Anforderung in besonderem Masse erfüllen.Attempts have been made to improve the properties of m-phenyldiamines by introducing substituents. In this connection, reference is made to DE-OS 29 34 330, in which, among other things, also colorants are described which contain special N-substituted m-phenylenediamines as coupler substances. With the currently known colorants, however, it is not possible to meet the requirements placed on a colorant in all respects. There was therefore still a need for new developer substances which particularly meet the aforementioned requirement.
Es wurde nun überraschend gefunden, dass bei Verwendung von N-Benzyl-m-phenylendiamin-Derivaten der allgemeinen Formel (I) intensive stabile purpurne bis blaue Farbnuancen erhalten werden.It has now surprisingly been found that when using N-benzyl-m-phenylenediamine derivatives of the general formula (I), intense stable purple to blue shades are obtained.
Gegenstand der vorliegende Erfindung sind daher N-Benzyl-m- phenylendiamin-Derivate der allgemeinen Formel (I) oder deren physiologisch verträgliche, wasserlösliche Salze, The present invention therefore relates to N-benzyl-m-phenylenediamine derivatives of the general formula (I) or their physiologically tolerable, water-soluble salts,

Für die Anwendung zur oxidativen Färbung von Haaren vermischt man das vorstehend beschriebene Färbemittel unmittelbar vor dem Gebrauch mit einem Oxidationsmittel und trägt eine für die Haarfärbebehandlung ausreichende Menge, je nach Haarfülle, im allgemeinen etwa 50 bis 200 Gramm, dieses Gemisches auf das Haar auf. Das nach dem Vermischen mit dem Oxidationsmittel erhaltene gebrauchsfertige Oxidationshaarfärbe- mittel hat vorzugsweise einen pH-Wert von etwa 6,5 bis 11 ,5.For use in the oxidative dyeing of hair, the colorant described above is mixed with an oxidizing agent immediately before use, and an amount sufficient for the hair dyeing treatment, depending on the fullness of the hair, generally about 50 to 200 grams, of this mixture is applied to the hair. The ready-to-use oxidation hair dye obtained after mixing with the oxidizing agent preferably has a pH of about 6.5 to 11.5.
Als Oxidationsmittel zur Entwicklung der Haarfärbung kommen hauptsächlich Wasserstoffperoxid oder dessen Additionsverbindungen an Harnstoff, Melamin, Natriumborat oder Natriumcarbonat in Form einer 3- bis 12-prozentigen, vorzugsweise 6-prozentigen, wässrigen Lösung, aber auch Luftsauerstoff in Betracht. Wird eine 6-prozentige Wasserstoffperoxid-Lösung als Oxidationsmittel verwendet, so beträgt das Gewichtsverhältnis zwischen Haarfärbemittel und Oxidationsmittel etwa 5:1 bis 1 :2, vorzugeweise jedoch etwa 1 :1. Grössere Mengen an Oxidationsmittel werden vor allem bei höheren Farbstoffkonzentrationen im Haarfärbemittel, oder wenn gleichzeitig eine stärkere Bleichung des Haares beabsichtigt ist, verwendet. Man läßt das Gemisch bei 15 bis 50 Grad Celsius etwa 10 bis 45 Minuten lang, vorzugsweise 30 Minuten lang, auf das Haar einwirken, spült sodann das Haar mit Wasser aus und trocknet es. Gegebenenfalls wird im Anschluß an diese Spülung mit einem Shampoo gewaschen und eventuell mit einer schwachen organischen Säure, wie zum Beispiel Zitronensäure oder Weinsäure, nachgespült. Anschließend wird das Haar getrocknet. Das erfindungsgemäße Färbemittel mit einem Gehalt an N-Benzyl-m- phenylendiamin-Derivaten der Formel (I) als Kupplersubstanz ermöglicht Färbungen mit ausgezeichneter Farbechtheit, insbesondere was die Lichtechtheit, Waschechtheit und Reibeechtheit anbetrifft. Hinsichtlich der färberischen Eigenschaften bietet das erfindungsgemäße Färbemittel je nach Art und Zusammensetzung der Farbkomponenten eine breite Palette verschiedener Farbnuancen, welche sich von blonden über braune, purpurne, violette bis hin zu blauen und schwarzen Farbtönen erstreckt. Hierbei zeichnen sich die Farbtöne durch ihre besondere Farbintensität aus. Die sehr guten färberischen Eigenschaften des Färbemittels gemäß der vorliegenden Anmeldung zeigen sich weiterhin darin, dass dieses Mittel insbesondere auch eine Anfärbung von ergrauten, chemisch nicht vorgeschädigten Haaren problemlos und mit guter Deckkraft ermöglicht.The main oxidizing agents used to develop hair color are hydrogen peroxide or its addition compounds with urea, melamine, sodium borate or sodium carbonate in the form of a 3 to 12 percent, preferably 6 percent, aqueous solution, but also atmospheric oxygen. If a 6 percent hydrogen peroxide solution is used as the oxidizing agent, the weight ratio between hair dye and oxidizing agent is approximately 5: 1 to 1: 2, but preferably approximately 1: 1. Larger amounts of oxidizing agent are used above all at higher dye concentrations in the hair dye or when more bleaching of the hair is intended at the same time. The mixture is allowed to act on the hair at 15 to 50 degrees Celsius for about 10 to 45 minutes, preferably 30 minutes, then the hair is rinsed with water and dried. If necessary, this rinse is washed with a shampoo and possibly rinsed with a weak organic acid, such as citric acid or tartaric acid. The hair is then dried. The colorant according to the invention with a content of N-benzyl-m-phenylenediamine derivatives of the formula (I) as a coupler substance enables dyeings with excellent color fastness, in particular with regard to light fastness, wash fastness and rub fastness. With regard to the coloring properties, the colorant according to the invention offers a wide range of different color nuances, depending on the type and composition of the color components, which ranges from blonde to brown, purple, violet to blue and black shades. The shades are characterized by their special color intensity. The very good coloring properties of the colorant according to the present application are further demonstrated by the fact that this means in particular also enables graying, chemically not previously damaged hair to be colored easily and with good coverage.
