Abstract
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.
