Agents for oxidatively dyeing keratinous fibers include, in a cosmetic carrier, as an oxidation dye precursor of the developer type, at least one compound of formula (I) as set forth herein, in which R1, R2 can stand independently of each other, for a hydrogen atom, different substituted alkyl groups, and/or different substituted acrylic groups, and Y stands for a hydroxyl group, an amino group, or a C1-C6 alkylamino group, with the proviso that at least one of the moieties from the group R1 and R2 does not stand for a hydrogen atom, and/or the physiologically compatible salt thereof. |

1. An agent for oxidatively dyeing keratinic fibers, including in a cosmetic carrier at least one compound of formula (I) as an oxidation dye precursor of the developer type: in which R1, R2 independently are a hydrogen atom, a C1-C6 alkyl group, a C2-C6 alkenyl group, a hydroxy-C1-C6 alkyl group, a polyhydroxy-C2-C6 alkyl group, a C1-C6 alkoxy-C1-C6 alkyl group, a hydroxy-C1-C6 alkyoxy-C1-C6 alkyl group, a C1-C6 alkoxy-C1-C6 alkyl group, a carboxy-C1-C6 alkyl group, a C1-C6 alkanoyl group, a C1-C6 alkoxycarbonyl group, a C1-C6 alkylaminocarbonyl group, a (di-C1-C6 alkylamino)carbonyl group, an aryl group, a heteroaryl group, or a (R3R4N)—C2-C6 alkyl group,
whereinR3, R4 independently are a hydrogen atom, a C1-C6 alkyl group, a hydroxy-C1-C6 alkyl group, an amino-C1-C6 alkyl group, a C1-C6 alkoxy-C1-C6 alkyl group, an aryl group, or a heteroaryl group, and Y is a hydroxy group, an amino group, or a C1-C6 alkylamino group, with the condition that at least one of the moieties from the group R1 and R2 does not stand for a hydrogen atom, or the physiologically acceptable salt thereof. |
