Mit Oxidationsfarbstoffen lassen sich zwar intensive Färbungen mit guten Echtheitseigenschaften erzielen, die Entwicklung der Farbe geschieht jedoch i.a. unter dem Einfluß von Oxidationsmitteln wie z. B. H2O2, was in einigen Fällen Schädigungen der Faser zur Folge haben kann. Desweiteren können einige Oxidationsfarbstoffvorprodukte bzw. bestimmte Mischungen von Oxidationsfarbstoffvorprodukten bisweilen bei Personen mit empfindlicher Haut sensibilisierend wirken. Direktziehende Farbstoffe werden unter schonenderen Bedingungen appliziert, ihr Nachteil liegt jedoch darin, daß die Färbungen häufig nur über unzureichende Echtheitseigenschaften verfügen. Aus dem Stand der Technik ist die Verwendung von Isatin in Kombination mit Oxidationsfarbstoffvorprodukten bekannt. In der europäischen Patentanmeldung 497 697 wird ein Verfahren zum Färben von keratinhaltigen Fasern beschrieben, worin als färbende Komponente eine Kombination aus Isatin und Indolderivaten eingesetzt wird.With oxidation dyes intensive dyeings can be achieved with good fastness properties, but the development of the color is usually done under the influence of oxidizing agents such. B. H 2 O 2 , which in some cases can damage the fiber. Furthermore, some oxidation dye precursors or certain mixtures of oxidation dye precursors can sometimes have a sensitizing effect on people with sensitive skin. Direct dyes are applied under gentler conditions, but their disadvantage is that the dyeings often have inadequate fastness properties. The use of isatin in combination with oxidation dye precursors is known from the prior art. European patent application 497 697 describes a process for dyeing keratin-containing fibers, in which a combination of isatin and indole derivatives is used as the coloring component.
In den europäischen Patentanmeldungen 502 783 und 502 784 werden Verfahren zum Färben von keratinhaltigen Fasern beschrieben, worin als färbende Komponenten jeweils eine Kombination aus Isatin und Pyridinderivaten bzw. Anilinderivaten eingesetzt werden.European patent applications 502 783 and 502 784 describe processes for dyeing keratin-containing fibers, in which a combination of isatin and pyridine derivatives or aniline derivatives are used as coloring components.
In der internationalen Patentanmeldung WO94/24988 werden Mittel zum Färben von keratinhaltigen Fasern offenbart, die als färbende Komponente Isatin oder ein beliebiges Derivat gemäß der dargestellten allgemeinen Formel in Kombination mit bestimmten primären aliphatischen Aminen, heterocyclischen aromatischen Verbindungen, aromatischen Carbon- und Sulfonsäuren, Anilinderivaten, Dianilinderivaten oder Aminozuckern enthalten. Die Verwendung der unten näher beschriebenen Nitroisatine in Kombination mit Oxidationsfarbstoffvorprodukten zum Färben von keratinhaltigen Fasern wird jedoch nicht explizit beschrieben.International patent application WO94 / 24988 discloses agents for dyeing keratin-containing fibers which, as the coloring component, contain isatin or any derivative according to the general formula shown in combination with certain primary aliphatic amines, heterocyclic aromatic compounds, aromatic carboxylic and sulfonic acids, aniline derivatives, Contain dianiline derivatives or amino sugars. However, the use of the nitroisatins described in more detail below in combination with oxidation dye precursors for dyeing fibers containing keratin is not explicitly described.
Aufgabe der vorliegenden Erfindung ist es, Färbemittel für Keratinfasern, insbesondere menschliche Haare, bereitzustellen, die hinsichtlich der Farbtiefe, der Grauabdeckung und den Echtheitseigenschaften qualitativ den üblichen Oxidationshaarfärbemitteln mindestens gleichwertig sind, ohne jedoch unbedingt auf Oxidationsmittel wie z. B. H202 angewiesen zu sein. Darüber hinaus dürfen die Färbemittel kein oder lediglich ein sehr geringes Sensibilisierungspotential aufweisen. Überraschenderweise wurde nun gefunden, daß sich eine Kombination aus den in der Formel I dargestellten Nitroisatinen und Oxidationsfarbstoffvorprodukten auch in Abwesenheit von oxidierenden Agentien besonders hervorragend zum Färben von keratinhaltigen Fasern eignet. Sie ergeben Ausfärbungen mit hervorragender Brillanz und Farbtiefe und führen zu vielfältigen Farbnuancen. Der Einsatz von oxidierenden Agenzien soll dabei jedoch nicht prinzipiell ausgeschlossen werden. Ferner wurde festgestellt, daß die Ausfärbungen verglichen mit dem unsubstituierten Isatin deutlich intensiver sind.The object of the present invention is to provide colorants for keratin fibers, in particular human hair, which are qualitatively at least equivalent to the usual oxidation hair colorants in terms of color depth, gray coverage and fastness properties, but without necessarily relying on oxidizing agents such as e.g. B. H 2 0 2 to be instructed. In addition, the colorants may have no or only a very low sensitization potential. Surprisingly, it has now been found that a combination of the nitroisatins and oxidation dye precursors shown in the formula I is particularly suitable for dyeing keratin-containing fibers, even in the absence of oxidizing agents. They result in colors with excellent brilliance and depth of color and lead to a wide range of shades. However, the use of oxidizing agents should not be excluded in principle. It was also found that the colorations are significantly more intense compared to the unsubstituted isatin.

Beispiele für geeignete ampholytische Tenside sind N-Alkylglycine, N-Alkylpropionsäuren, N-Alkylamino- buttersäuren, N-Alkyliminodipropionsäuren, N-Hydroxyethyl-N-alkylamidopropylg- lycine, N-Alkyltaurine, N-Alkylsarcosine, 2-Alkylaminopropionsäuren und Alkyl- aminoessigsäuren mit jeweils etwa 8 bis 18 C-Atomen in der Alkylgruppe. Besonders bevorzugte ampholytische Tenside sind das N-Kokosalkyl- aminopropionat, das Kokosacylaminoethylaminopropionat und das C12-18- Acylsarcosin. Nichtionische Tenside enthalten als hydrophile Gruppe z. B. eine Polyolgruppe, eine Polyalkylenglykolethergruppe oder eine Kombination aus Polyol- und Po- lyglykolethergruppe. Solche Verbindungen sind beispielsweiseAmpholytic surfactants are understood to mean those surface-active compounds which, in addition to a C 8 . 18 -alkyl or -acyl group in the molecule contain at least one free amino group and at least one -COOH or -S0 3 H group and are capable of forming internal salts.

Cetyltrimethylammoniumchlorid, Stearyltrimethylammoniumchlorid, Distea- ryldimethylammoniumchlorid, Lauryldimethylammoniumchlorid, Lauryldimethyl- benzylammoniumchlorid und Tricetylmethylammoniumchlorid. Weitere erfindungsgemäß verwendbare kationische Tenside stellen die quaternisierten Proteinhydrolysate dar.Examples of the cationic surfactants which can be used in the hair treatment compositions according to the invention are, in particular, quaternary ammonium compounds. Ammonium halides such as alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides and trialkylmethylammonium chlorides, e.g. B. cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammonium chloride, lauryldimethylbenzylammonium chloride and tricetylmethylammonium chloride. The quaternized protein hydrolyzates are further cationic surfactants which can be used according to the invention.
Erfindungsgemäß ebenfalls geeignet sind kationische Silikonöle wie beispielsweise die im Handel erhältlichen Produkte Q2-7224 (Hersteller: Dow Corning; ein stabilisiertes Trimethylsilylamodimethicon), Dow Corning 929 Emulsion (enthaltend ein hydroxyl-amino-modifiziertes Silicon, das auch als Amodime- thicone bezeichnet wird), SM-2059 (Hersteller: General Electric), SLM-55067 (Hersteller: Wacker) sowie Abil®-Quat 3270 und 3272 (Hersteller: Th. Goldschmidt; diquatemäre Polydimethylsiloxane, Quatemium-80).Also suitable according to the invention are cationic silicone oils such as, for example, the commercially available products Q2-7224 (manufacturer: Dow Corning; a stabilized trimethylsilylamodimethicone), Dow Corning 929 emulsion (containing a hydroxylamino-modified silicone, which is also referred to as amodimethicone) , SM-2059 (manufacturer: General Electric), SLM-55067 (Manufacturer: Wacker) and Abil ® -Quat 3270 and 3272 (manufacturer: Th. Goldschmidt; diquaternary polydimethylsiloxanes, Quatemium-80).
Alkylamidoamine, insbesondere Fettsäureamidoamine wie das unter der Bezeichnung Tego Amid®S 18 erhältliche Stearylamidopropyldimethylamin, zeichnen sich neben einer guten konditionierenden Wirkung speziell durch ihre gute biologische Abbaubarkeit aus.In addition to a good conditioning effect, alkylamidoamines, especially fatty acid amidoamines such as the stearylamidopropyldimethylamine available under the name Tego Amid ® S 18, are notable for their good biodegradability.
Ebenfalls sehr gut biologisch abbaubar sind quaternäre Esterverbindungen, sogenannte "Esterquats", wie die unter dem Warenzeichen Stepantex® vertriebenen Methylhydroxyalkyldialkoyloxyalkylammoniummethosulfate.Also very good biodegradability are quaternary Esterverbindungen, so-called "esterquats", such as those sold under the trademark Stepantex ® methylhydroxyalkyldialkoyloxyalkylammonium.
Ein Beispiel für ein als kationisches Tensid einsetzbares quatemäres Zuckerderivat stellt das Handelsprodukt Glucquat®100 dar, gemäß CTFA-Nomenklatur ein "Lauryl Methyl Gluceth-10 Hydroxypropyl Dimonium Chloride".An example of a suitable cationic surfactant quaternary sugar derivative is the commercial product Glucquat ® 100, according to CTFA nomenclature a "lauryl methyl Gluceth-10 Hydroxypropyl Dimonium Chloride".
Bei den als Tenside eingesetzten Verbindungen mit Alkylgruppen kann es sich jeweils um einheitliche Substanzen handeln. Es ist jedoch in der Regel bevorzugt, bei der Herstellung dieser Stoffe von nativen pflanzlichen oder tierischen Rohstoffen auszugehen, so daß man Substanzgemische mit unterschiedlichen, vom jeweiligen Rohstoff abhängigen Alkylkettenlängen erhält.The compounds with alkyl groups used as surfactants can each be uniform substances. However, it is generally preferred to start from natural vegetable or animal raw materials in the production of these substances, so that substance mixtures with different alkyl chain lengths depending on the respective raw material are obtained.
Bei den Tensiden, die Anlagerungsprodukte von Ethylen- und/oder Propylenoxid an Fettalkohole oder Derivate dieser Anlagerungsprodukte darstellen, können sowohl Produkte mit einer "normalen" Homologenverteilung als auch solche mit einer eingeengten Homologenverteilung verwendet werden. Unter "normaler" Homologenverteilung werden dabei Mischungen von Homologen verstanden, die man bei der Umsetzung von Fettalkohol und Alkylenoxid unter Verwendung von Alkalimetallen, Alkalimetallhydroxiden oder Alkalimetallalkoholaten als Katalysatoren erhält. Eingeengte Homologenverteilungen werden dagegen erhalten, wenn beispielsweise Hydrotalcite, Erdalkalimetallsalze von Ethercarbonsäuren, Erdalkalimetalloxide, -hydroxide oder -alkoholate als Katalysatoren verwendet werden. Die Verwendung von Produkten mit eingeengter Homologenverteilung kann bevorzugt sein.In the case of the surfactants, which are addition products of ethylene and / or propylene oxide onto fatty alcohols or derivatives of these addition products, both products with a "normal" homolog distribution and those with a narrowed homolog distribution can be used. “Normal” homolog distribution is understood to mean mixtures of homologues which are obtained as catalysts when fatty alcohol and alkylene oxide are reacted using alkali metals, alkali metal hydroxides or alkali metal alcoholates. By contrast, narrow homolog distributions are obtained if, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, Alkaline earth metal oxides, hydroxides or alcoholates can be used as catalysts. The use of products with a narrow homolog distribution can be preferred.
