    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 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 multi-step process for dyeing keratin fibres, human keratin fibres such as the hair, in which said fibres are treated with: i) at least one step i) of treating said fibres using a cosmetic composition Ci) comprising a) one or more titanium salts and b) optionally one or more particular carboxylic acids; ii) at least one step of dyeing with a colouring cosmetic composition Cii) comprising c) one or more synthetic direct dyes, preferably chosen from anionic direct dyes; iii) optionally at least one step of intermediate rinsing of said fibres, said step being performed between step i) and ii) or between step ii) and i), depending on the order in which said steps i) and ii) are performed.

    Abstract: The subject of the present invention is a process for the oxidation dyeing of keratin fibers, in particular human keratin fibers such as the hair, implementing: a) a step of treating said fibers by application to said fibers of a cosmetic composition (A) comprising: i) at least one fatty substance in an amount of greater than 10% by weight relative to the total weight of the composition (A), at least one metal catalyst; ii) at least one coupler; iii) optionally at least one oxidation base, preferably chosen from para-phenylenediamines, bis(phenyl)alkylenediamines, para-aminophenols, ortho-aminophenols, heterocyclic bases, addition salts thereof and solvates thereof; b) optionally a washing, rinsing, drying and/or rubbing-dry step; c) a step of treatment by application to said fibers of an oxidizing cosmetic composition (B) comprising at least one chemical oxidizing agent; and it being understood that steps a), b) and c) can be carried out successively a), then b), then c), or else a) then c), followed by b). 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, as a 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.
