    Abstract: Process for dyeing keratinous fibres, wherein at least one composition (A) containing at least one aminoindole in a medium suitable for dyeing is applied on these fibres, the application of the composition (A) being preceded or followed by the application of a composition (B) containing at least one quinone derivative chosen from ortho- or para-benzoquinones, ortho- or para-benzoquinone monoimines or diimines, 1,2- or 1,4-naphthoquinones, ortho- or para-benzoquinone sulphonimides, alpha , omega -alkylene bis(1,4-benzoquinones) or 1,2- or 1,4-naphthoquinone monoimines or diimines in a medium suitable for dyeing, the aminoindoles and the quinone derivatives being chosen in such a way that the difference in oxidation-reduction potential DELTA E between the oxidation-reduction potential Ei of the aminoindoles, determined at pH 7 in a phosphate medium with a vitreous carbon electrode by voltammetry, and the oxidation-reduction potential Eq of the quinone derivative, determined at pH 7 in phosphate medium by polarography with a mercury electrode relative to the saturated calomel electrode, is such that: DELTA E = Ei-Eq

    Abstract: Process for dyeing keratinous fibres, comprising the step of applying to these fibres at least one composition A containing, in a medium appropriate for dyeing, at least one mono- or di-hydroxyindole the application of the composition A being preceded or followed by the application of a composition B containing, in a medium appropriate for dyeing, at least one quinone derivative chosen from ortho- or para-benzoquinones, monoimines or diimines of ortho- or para-benzoquinones, 1,2- or 1,4-naphthoquinones, sulphonimides of ortho- or para-benzoquinones, alpha , omega -alkylene-bis-1,4-benzoquinones, or 1,2- or 1,4-naphthoquinone-monoimines or -diimines; the mono- or di-hydroxyindoles and the quinone derivatives being chosen such that the oxidation-reduction potential difference DELTA E between the oxidation-reduction potential Ei of the mono- or di-hydroxyindoles, determined at pH 7 in a phosphate medium on a vitreous carbon electrode by voltametry, and the oxidation-reduction potential Eq of the quinone derivative determined at pH 7 in a phosphate medium by polarography on a mercury electrode and relative to a saturated calomel electrode is such that DELTA E=Ei-Eq
