Patent ID: 8864849

Claim:
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 C 1 -C 6 alkyl group, a C 2 -C 6 alkenyl group, a hydroxyl group, a halogen, a C 1 -C 6 alkoxy group, an amino group, a nitro group, an acetyl amino group, or a sulfonamide group; or when 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 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 cyano-C 1 -C 6 alkyl group, or a —Y′—O—SO 2 —O − M + group; Y and Y′ independently of one another 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(R6′)-(CH 2 ) 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 C 1 -C 6 alkylamino group, a di-(C 1 -C 6 alkyl)amino group, a hydroxyl group, a C 1 -C 6 alkoxy group, a C 1 -C 6 alkyl group, a C 2 -C 6 alkenyl group, a carboxylic acid group, a sulfonic acid group, a halogen, an acetylamino group, or a sulfonamide group; or when 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 C 1 -C 6 alkyl group, a C 2 -C 6 alkenyl group, or a C 2 -C 6 hydroxyalkyl group; and M + denotes a proton (H + ), an alkali metal cation, or a half equivalent of an alkaline-earth metal cation.
