    Abstract: The invention relates to a process for dyeing keratin fibers by treating said fibers with i) at least one aromatic compound comprising a hydrocarbon-based polycycle comprising at least 10 carbon atoms, at least one of the rings of which is aromatic, ii) at least one indol(in)e compound; optionally iii) at least one metal salt, iv) at least hydrogen peroxide or at least one hydrogen peroxide-generating system and v) at least one basifying agent; to a dye composition comprising ingredients i) and ii), and optionally iii) to v) as defined previously and to a kit comprising ingredients i) to v) as defined previously. This hair dyeing process makes it possible to obtain better colorings which are more uniform, chromatic and long-lasting and which do not impair the cosmetic properties of the keratin fibers, and prevents changing of the color associated with the presence of indol(in)e derivatives.

    Abstract: The invention relates to a process for dyeing keratin fibers, comprising the use of one or more metal catalysts and of a composition (A) comprising: —one or more oxidizing agents, and —at least one monoaminobenzene of formula (I), or an addition salt or solvate thereof in which the radicals R1 to R5 represent, independently of each other: a hydrogen atom; a halogen atom, a C1-C6 alkyl radical, a C1-C6 alkoxy radical, a carboxylic radical (—COOH), a sulfonic radical (—S03 H); two of the adjacent radicals R1 to R5 possibly forming, with the carbon atoms that bear them, a saturated or unsaturated 5- to 7-membered ring, optionally comprising from 1 to 2 heteroatoms, preferably oxygen, the said ring being optionally fused with a saturated or unsaturated 5- to 6-membered ring; on condition that at least one of the radicals R1 to R5 represents an optionally substituted alkoxy radical and preferably at least one of the other radicals R1 to R5 is a hydrogen atom.

    Abstract: The present invention relates to a composition for dyeing keratin fibres, comprising: at least one fatty substance, at least one surfactant; at least one oxidation base, at least one coupler of formula (B3) below and also salts thereof, optical and geometrical isomers and tautomers thereof, and hydrates thereof: (B3) in which; R1, R3, R5 represent a hydrogen; a C1-C8 alkyl or alkenyl, —SR or —OR; a (C1-C4)alkylcarbonyl; hydrocarbonyl; sulphonic or carboxylic acid; R2, R4 represent a hydrogen, a C1-C8 alkyl or alkenyl; —OR′; two groups chosen from R1, R2, R3, R4, R5 and borne by adjacent carbon atoms may form, together with said carbon atoms, a ring or a heterocycle which is optionally substituted, and which is optionally interrupted with one or more carbonyl groups; at least one of the radicals R1, R3, R5 representing a hydrogen; at least one of the radicals R2 or R4 denoting a group —OR′ with R′ representing a C1-C8 alkyl or alkenyl, it being possible for this radical to form, with the carbon atom bearing it, one of the neighbouring carbon atoms and its substituent, a heterocycle; at least one alkalinizing agent; the fatty substance content representing in total at least 25% by weight relative to the total weight of the composition. The present invention also relates to a process using this composition in the presence of at least one chemical oxidizing agent, and to multicompartment devices suitable for the implementation of the invention.

    Abstract: The present invention relates to a process for the oxidation dyeing of keratin fibers implementing: a) a step of pretreating said fibers by application to said fibers of a cosmetic composition (B) comprising: i) at least one fatty substance in an amount of greater than or equal to 10% by weight relative to the total weight of the composition (B); and ii) at least one metal catalyst; b) optionally a washing, rinsing, drying and/or rubbing-dry step; c) followed by a step of dyeing by application to said fibers of a cosmetic composition (A) comprising: i) at least one oxidation base, preferably chosen from para-phenylenediamines, bis(phenyl)alkylenediamines, para-aminophenols, ortho-aminophenols, heterocyclic bases preferably comprising at least two nitrogen atoms, and addition salts thereof; ii) optionally at least one coupler; and iii) at least one chemical oxidizing agent. The dyeing process makes it possible to significantly improve the dyeing properties of the coloration, in particular in terms of selectivity, of chromaticity, and of color intensity and uptake. The use of a composition which is rich in fatty substances, i.e. greater than 10%, and contains at least one catalyst pretreatment, before oxidation dyeing, allows a clear improvement in the dyeing properties, in particular in terms of dye uptake onto keratin fibers, of strength and of chromaticity and of selectivity of the color.
