The invention relates to an agent for dyeing keratin containing fibers, especially human hair, comprising at least one cyclopentaquinoxalinium derivative of the formula (I), wherein R<1>, R<2>, R<3> independently represent a hydrogen atom or a C1-C4 alkyl group, and R<1> and R<2> together may form a ring, X<1> and X<2> represent an oxygen or sulfur atom or together a 1,2-arylenediimino group that in turn can be substituted in the aromatic group by halogen atoms, C1-C4 alkyl, C1-C4 alkoxy, nitro, amino, C1-C4 alkyl, C1-C4 alkylamino, hydroxy, carboxy, or sulfo groups or an additional condensed aromatic ring and is quaternated on one of the nitrogen atoms by a C1-C6 alkyl, aralkyl, aryl, C2-C4 alkenyl, or C1-C6 hydroxyalkyl, or carboxyalkyl group, and wherein the additional condensed aromatic ring may be substituted by halogen atoms, in halogen atoms, C1-C4 alkyl, C1-C4 alkoxy, nitro, amino, C1-C4 alkyl, C1-C4 alkylamino, hydroxy, carboxy, or sulfo groups. The invention further relates to the tautomeric forms or the physiologically acceptable salts of the inventive derivative. |
