Patent Interference No. 103,548 17. A method according to claim 9, wherein composition (A) is applied to the keratinous fibres and composition (B), containing a metal salt comprising a manganese, cobalt, iron, copper or silver salt, is applied before or after the composition (A). 18. A method according to claim 17, wherein the metal salt is used in a proportion of between 0.01 and 2% by weight, expressed as metal ions, relative to the total weight of the composition. Corresponds to Count 3. 19. A method according to claim 9, wherein composition (A) is applied and, before or after this composition, composition (B) containing a rare-earth salt selected from the group consisting of a cerium, lanthanum, europium, gadolinium, ytterbium and dysprosium salt is applied. 20. A method according to claim 19, wherein a the rare-earth salt is present in a proportion of between 0.1 and 8% by weight relative to the total weight of the composition. 21. A method according to claim 9, wherein a composition based on hydrogen peroxide is used as the oxidizing medium, the hydrogen peroxide content in the composition being between 1 and 40 volumes. 22. A multicomponent agent for dyeing keratinous fibres, in particular human keratinous fibres, comprising a first component consisting of a composition (A) containing a 5,6-dihydroxyindoline corresponding to formula (I): HO CH2 CH2 (I) HO N R in which R represents a hydrogen atom or a C1-C4 alkyl group, or an acid addition salt thereof, and a second component consisting of a composition (B) which contains, in a medium appropriate for dyeing, either: (a) hydrogen peroxide at a pH of between 2 and 12 when the composition (A) contains iodide ions, or (b) iodide ions at a pH of between 3 and 11, when the composition (A) contains hydrogen peroxide.Page: Previous 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 NextLast modified: November 3, 2007
