Abstract:
1. A ready-to-use agent for coloring keratin fibers, wherein said ready-to-use agent contains (a) at least one hydrazone derivative of formula (I), or a physiologically compatible salt thereof: wherein X denotes oxygen, sulfur or N—R2, Y denotes C—R3 or nitrogen, and Z denotes C—R4 or nitrogen, provided that a heterocyclic ring in said at least one hydrazone derivative of the formula (I) contains at the most three hetero atoms; A denotes hydrogen, an acetyl group, a trifluoroacetyl group, a formyl group, a (C R1 and R2 are the same or different and, independently of each other, denote a saturated or unsaturated (C R3 and R4 are the same or different and, independently of each other, denote hydrogen, a halogen atom, a saturated or unsaturated (C and when Y and Z denote C—R3 and C—R4, R3 and R4 together with a remainder of the hydrazone derivative can form a heterocyclic or carbocyclic, saturated or unsaturated, substituted or unsubstituted ring system; (b) at least one CH-active compound selected from the group consisting of compounds of formulas (II) to (IX) as follows: wherein R5 denotes a cyano group, a (CO)—R6 carbonyl group, wherein R6 denotes a (C 1 -C 12 )-alkoxy group, an amino group, a (C 1 -C 12 )-alkylamino group, a (C 1 -C 12 )-alkyl group or an aryl group; wherein R7 and R8 are the same or different and, independently of each other, denote hydrogen, a (C 1 -C 12 )-alkyl group, a monohydroxy-(C 1 -C 12 )-alkyl group, a polyhydroxy-(C 2 -C 12 )-alkyl group, a mono-(C 1 -C 6 )-alkoxy-(C 1 -C 6 )-alkyl group, a poly-(C 1 C 6 )-alkoxy-(C 2 -C 6 )-alkyl group, an amino-(C 1 -C 12 )-alkyl group, or a carbocyclic or heterocyclic, substituted or unsubstituted aromatic compound, and D denotes a sulfur atom or an oxygen atom; wherein R9 denotes a hydrogen atom, a nitrile group, a (C 1 -C 12 )-alkyl group, a carbocyclic or heterocyclic aromatic compound or a (CO)—R12 carbonyl group, wherein R12 denotes hydrogen, a hydroxyl group,a (C 1 -C 12 )-alkoxy group, an amino group, a (C 1 -C 12 )-alkylamino group, a (C 1 -C 12 )-alkyl group, or an aryl group; and R10 and R11 are the same or different and, independently or each other, denote hydrogen, a (C wherein E denotes an oxygen atom, a sulfur atom of an NR′ amino group, with R′ denoting hydrogen or a substituted or unsubstituted (C 1 -C 12 )-alkyl group, and R13 denotes a hydrogen atom, a halogen atom, a hydroxyl group, a cyano group, a nitro group, a (C wherein G and G′ are the same or different and, independently or each other, denote an oxygen atom, a sulfur atom, or an NR″ amino group, with R″ denoting hydrogen or a substituted or unsubstituted (C 1 -C 12 )-alkyl group, R14 denotes hydrogen, a substituted or unsubstituted (C wherein V denotes an oxygen atom or an NR″′ amino group, with R″′ denoting hydrogen or a substituted or unsubstituted-(C 1 -C 12 )-alkyl group; and R15 denotes a hydrogen atom, a halogen atom, a hydroxyl group, a cyano group, a nitro group, a (C and (c) at least one oxidant.
