Patent ID: 6974485

Claim:
A composition for dyeing keratin fibres by oxidation dyeing comprising, in a medium suitable for dyeing the keratin fibres, at least one extract of Myrsine africana and at least one compound chosen from compounds of formula (I) and cosmetically acceptable acid and base addition salts thereof: wherein: R 1 is chosen from radicals of NR 4 R 5 , wherein R 4 and R 5 , which may be identical or different, are chosen from a hydrogen atom and alkyl radicals optionally substituted with at least one radical chosen from hydroxyl, alkoxy, carboxyl, amino, monoalkylamino and dialkylamino radicals in which the alkyl radical is optionally substituted with at least one radical chosen from hydroxyl, alkoxy, carboxyl, amino, monoalkylamino and dialkylamino radicals; or R 4 and R 5 form, together with the nitrogen atom to which they are attached, a 5- to 8-membered saturated heterocycle, the heterocycle possibly being substituted with at least one entity chosen from halogen atoms, hydroxyl, alkoxy, carboxyl, amino, carboxamido, sulphonamido, monoalkylamino and dialkylamino radicals, and C 1 -C 6 alkyl radicals optionally substituted with at least one radical chosen from hydroxyl, amino, carboxyl, monoalkylamino and dialkylamino radicals; the heterocycle optionally comprising at least one additional hetero atom chosen from O, S, SO 2 and NR″, wherein R″ is chosen from a hydrogen atom and C 1 -C 4 alkyl radicals; R 2 is chosen from radicals of NR 6 R 7 , wherein R 6 and R 7 , which may be identical or different, are chosen from a hydrogen atom and alkyl radicals optionally substituted with at least one radical chosen from hydroxyl, alkoxy, carboxyl, amino, monoalkylamino and dialkylamino radicals in which the alkyl radical is optionally substituted with at least one radical chosen from hydroxyl, alkoxy, carboxyl, amino, monoalkylamino and dialkylamino radicals; or R 6 and R 7 form, together with the nitrogen atom to which they are attached, a 5- to 8-membered saturated heterocycle, the heterocycle possibly being substituted with at least one entity chosen from halogen atoms, hydroxyl, alkoxy, carboxyl, amino, carboxamido, sulphonamido, monoalkylamino and dialkylamino radicals, and C 1 -C 6 alkyl radicals optionally substituted with at least one radical chosen from hydroxyl, amino, carboxyl, monoalkylamino and dialkylamino radicals, the heterocycle optionally comprising at least one additional hetero atom chosen from O, S, SO 2 and NR″, wherein R″ is chosen from a hydrogen atom and C 1 -C 4 alkyl radicals; and X—Y is chosen from RC—CR′ and N—CR, wherein R and R′, which may be identical or different, are chosen from a hydrogen atom, alkyl, hydroxyl, and amino radicals.
