    摘要： The invention relates to o-aminophenol derivatives of general formula (I) or to their physiologically compatible water-soluble salts. In said formula: X represents oxygen, sulphur or N-R4; R1, R2, R3 can be identical or different and independently of one another represent hydrogen, a halogen atom a cyano group, a C1-C4 alkoxy group, a C1-C6 alkyl group, a C1-C4 alkyl-thioether group, a mercapto group, a nitro group, a trifluoromethane group, a -C(O)H- group, a -C(O)CH3- group, a -C(O)CF3- group, a -Si(CH3)3- group, a C1-C4 hydroxy alkyl group or an aminomethyl group; R4 represents hydrogen, a C1-C6 alkyl group, a C1-C4 hydroxyalkyl group, a phenyl group or an acetyl group. The invention also relates to colorants containing said compounds for use on keratin fibres.

    摘要： Disclosed are compounds of formula (I) and agents for dyeing keratin fibers, especially hair, which contain said 4-amino-biphenyl-3-ol-derivatives of general formula (I). The following applies: R1 and R2 independently represent hydrogen, a halogen atom, a cyano group, hydroxy group, C1-C4-alkoxy group, C2-C4 hydroxyalkoxy group, C1-C6 alkyl group, nitro group, trifluoromethane group, -C(O)H group, -C(O)CH3 group, -C(O)CF3 group, -Si(CH3)3 group, or C1-C6- hydroxyalkyl group, or R1 and R2 jointly form an -O-CH2-O bridge.
