Claim:
An agent for coloring keratinic fibers included in a cosmetic carrier, the agent comprising: at least one compound of the formula (I), in which: R1 and R2 mutually independently denote hydrogen, a C 1 -C 6 alkyl group, a C 2 -C 6 alkenyl group, a hydroxyl group, a C 1 -C 6 alkoxy group, halogen, an amino group, an acetylamino group, a nitro group, or a nitrile group, or alternatively, R1 and R2 form a 5- or 6-membered, saturated or unsaturated, carbocyclic or heterocyclic ring if R1 and R2 are in ortho position relative to one another; X denotes O or N—R3; R3 denotes hydrogen, a C 1 -C 6 alkyl group, a C 2 -C 6 alkenyl group, a C 2 -C 6 hydroxyalkyl group, a C 2 -C 6 polyhydroxyalkyl group, a C 1 -C 6 cyanoalkyl group, an aryl-C 1 -C 6 -alkyl group, or a group —Y′—O—SO 2 —OM; Y and Y′, in each case, mutually independently denote (CH 2 ) n , C 2 H 4 —(OC 2 H 4 ) n , (CH 2 ) n —O—(CH 2 ) m , or (CH 2 ) n —N(R8)-(CH 2 ) m , in which n and m in each case mutually independently denote an integer from 1 to 6, A denotes one of structures (II) to (XIII), in which: R4 and R5, in each case, mutually independently denote hydrogen, a C 1 -C 6 alkyl group, a C 2 -C 6 alkenyl group, a hydroxyl group, a C 1 -C 6 alkoxy group, halogen, an amino group, an acetylamino group, a C 1 -C 6 alkylsulfonyl group, or a nitrile group, or R4 and R5 form a 5- or 6-membered, saturated or unsaturated, carbocyclic or heterocyclic ring if R4 and R5 are in ortho position relative to one another; R6 and R7 mutually independently denote a C 1 -C 6 alkyl group, a C 2 -C 6 alkenyl group, or a C 2 -C 6 hydroxyalkyl group; R8 denotes hydrogen, a C 1 -C 6 alkyl group, a C 2 -C 6 alkenyl group, or a C 2 -C 6 hydroxyalkyl group; and M denotes hydrogen, an alkali metal or half an equivalent of an alkaline earth metal.
