    Abstract: Oxidation dyeing composition intended for use for dyeing keratinous fibres, especially human keratinous fibres, and in particular the hair, which contains, in a solvent medium suitable for dyeing these fibres, at least one para oxidation dye precursor or at least one ortho oxidation dye precursor and at least one heterocyclic coupler corresponding to the formula (I): in which: R1 and R3, which may be identical or different, denote a hydrogen atom or a C1-C4 alkyl group; R2 denotes a hydrogen atom, a C1-C4 alkyl group, a carboxyl group or an alkoxycarbonyl group; at least one of the radicals R2 or R3 denoting hydrogen; R4 denotes a hydrogen atom or a C1-C4 alkyl or C1-C4 hydroxyalkyl or C2-C4 polyhydroxyalkyl group; the group NHR4 occupying positions 4, 6 or 7 of the benzene ring, as well as their salts.

    Abstract: The invention relates to the use, as coupler in a dyeing composition, of a hydroxybenzofuran of formula (I): (I) in which R1 and R2, which are identical or different, represent a hydrogen atom or a C1-C6 alkyl radical. When they denote an alkyl radical, R1 and R2 can occupy any position on the benzofuran ring except the positions 2 and 3 at the same time. The OH group may occupy one of the positions 4, 5, 6 or 7, in combination with one or more para type or ortho type oxidation dye precursors or mixtures thereof, for dyeing keratinous fibers and in particular human hair. The dyeing composition according to the invention makes it possible to confer on the keratinous fibers a color which is fast to light, washes, adverse weather conditions and perspiration.
