The present invention relates to a composition for dyeing keratin fibres, comprising: - one or more fatty substances, - one or more surfactants; - one or more oxidation bases, - one or more phenol-derived couplers corresponding to the formula (B2) below: * R 1 , R 3 , R 5 , represent a hydrogen; an optionally substituted C 1 -C 8 alkyl or alkenyl radical; -SR or -OR; a saturated C 5 -C 7 cyclic group; a (C 1 -C 4 )alkylcarbonyl group; hydrocarbonyl; a sulphonic or carboxylic acid group; * at least one of the radicals R 1 , R 3 , R 5 representing a hydrogen atom; * R 2 , R 4 represent a hydrogen; an optionally substituted C 1 -C 8 alkyl or alkenyl; -SR; a (C 1 -C 4 )alkylcarbonyl; hydrocarbonyl; a sulphonic or carboxylic acid group; * two groups chosen from R 1 , R 2 , R 3 , R 4 , R 5 and borne by adjacent carbon atoms may form, together with said carbon atoms, a ring or a heterocycle with a single heteroatom, this ring or heterocycle comprising no double bond other than that of the ring to which it is fused; * at least one of the radicals R 1 , R 2 , R 3 , R 4 , R 5 being other than hydrogen; - one or more alkalinizing agents; 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. |
