Abstract:
1. An agent for the simultaneous lightening and coloring of keratin fibers, comprising at least one oxidizing agent, characterized by comprising at least one azodye of the general formula (I); wherein X is selected from the group consisting of oxygen, sulfur, N—R3 and C—R4; Y is selected from the group consisting of C—R5, nitrogen, N—R6, sulfur and oxygen; Z is C—R7 or nitrogen; wherein the heterocycle of the formula (I) comprises at least two and at most three heteroatoms, where the heterocycle comprises at most one sulfur atom or one oxygen atom; n is an integer from 1 to 6; R1 is selected from the group consisting of hydrogen, a saturated or unsaturated (C R2, R4, R5, and R7 may be identical or different and, independently of one another, are selected from the group consisting of hydrogen, a halogen atom, a saturated or unsaturated (C or if Y and Z are C—R5 and C—R7, the radical groups R5 and R7, together with the remaining molecule, can form a heterocyclic or carbocyclic, saturated or unsaturated, substituted or unsubstituted ring system; or if X and Y are C—R4 and C—R5, the radical groups R4 and R5, together with the remaining molecule, can form a heterocyclic or carbocyclic, saturated or unsaturated, substituted or unsubstituted ring system; R3 and R6 may be identical or different and, independently of one another, are selected from the group consisting of a saturated or unsaturated (C Q+ represents a quaternary monoalkylammonium, dialkylammonium or trialkylammonium group, where the alkylgroups may be identical or different and, independently of one another, are a saturated or unsaturated (C wherein when Q+ represents a tri(C or Q+ represents a quaternary mononoarylammonium, diarylammonium or triarylammonium group, where the arylgroups may be identical or different and, independently of one another, are an unsubstituted or substitued phenylgroup; or Q+ represents a quaternary alkylarylammonium group, where the alkylgroups may be identical or different and, independently of one another, are a saturated or unsaturated (C
