| titleOfInvention | Agent for dying keratin fibers |
| abstract | The invention relates to an agent for dying keratin fibers, especially human hair, containing an aromatic and/or heteroaromatic aldehyde or a ketone with formula (I), in which: R<1> represents a hydrogen atom, a low C1-C4 alkyl group, an aryl group, or a heteroaryl group; R<2> and R<3> represent a hydrogen atom, a halogen atom, a C1-C4 alkyl group, a C1-C4 alkoxy group or a C1-C4 hydroxyalkoxy group, a hydroxy group, a nitro group, an amino group, which can be substituted by C1-C4 alkyl groups, and R<2> and R<3>, together with the nitrogen atom, can form a heterocyclic ring, whereby both radicals R<2> and R<3> can also be joined together to form a fused aromatic ring; R<4> represents a low C1-C4 alkyl group, a C1-C4 alkenyl group, an aryl group, an aralkyl group, a C1-C4 carbocyalkyl group, or a C1-C4 sulfoalkyl group; R<5> and R<6> represent a hydrogen atom and halogen atom, a C1-C4 alkyl group, a C1-C4 alkoxy group or a C1-C4 hydroxyalkoxy group, a hydroxy group, a nitro group and an amino group, which can be substituted by C1-C4 alkyl groups, and R<5> and R<6>, together with the nitrogen atom, can form a heterocyclic ring, whereby both radicals R<5> and R<6> can also be joined together to form a fused aromatic ring; Q represents a direct bond, a methylene group or ethylene group; Y and X represent a nitrogen atom substituted by an aralkyl group or aryl group, an oxygen atom, a sulfur atom or an optionally substituted vinylene group, and; Z<-> represents an anion such as halogenide, C1-C4 alkyl sulfate, C1-C4 alkane sulfonate, arene sulfonate, C1-C4 perfluoroalkane sulfate, perhalogenate, sulfate, hydrogen sulfate, carboxylate, tetrafluoroborate, hexafluorophosphate or tetrachlorozincate, whereby the bond to the quaternized heterocycle is preferably fixed in the 2-position and, for Y = vinylene, is also fixed in the 4-position. |
