1. An agent for coloring keratinic fibers, the agent comprising, in a cosmetic carrier, at least one compound of formula (I), in which:
R1 and R2:
independently of one another denote hydrogen, a C1-C6 alkyl group, a C2-C6 alkenyl group, a hydroxyl group, a halogen, a C1-C6 alkoxy group, an amino group, a nitro group, an acetyl amino group, or a sulfonamide group; orwhen in ortho-position to one another, form a 5- or 6-membered, saturated or unsaturated ring, which optionally comprise further heteroatoms;X denotes O or N—R3;R3 denotes hydrogen, a C1-C6 alkyl group, a C2-C6 alkenyl group, a C2-C6 hydroxyalkyl group, a C2-C6 polyhydroxyalkyl group, a cyano-C1-C6 alkyl group, or a —Y′—O—SO2—O−M+ group;Y and Y′ independently of one another denote (CH2)n, C2H4—(OC2H4)n, (CH2)n—O—(CH2)m, or (CH2)n—N(R6′)-(CH2)m, in which n, and optionally m, each denote a whole number from 1 to 6;A denotes one of the structures (II) to (XV), R4 and R5
independently of one another denote hydrogen, an amino group, a C1-C6 alkylamino group, a di-(C1-C6 alkyl)amino group, a hydroxyl group, a C1-C6 alkoxy group, a C1-C6 alkyl group, a C2-C6 alkenyl group, a carboxylic acid group, a sulfonic acid group, a halogen, an acetylamino group, or a sulfonamide group; orwhen in ortho-position to one another, form a 5- or 6-membered, saturated or unsaturated ring, which optionally includes further heteroatoms;R6 and R6′ each independently of one another denote a hydrogen atom, a C1-C6 alkyl group, a C2-C6 alkenyl group, or a C2-C6 hydroxyalkyl group; andM+ denotes a proton (H+), an alkali metal cation, or a half equivalent of an alkaline-earth metal cation. |
