TINCTORIAL COMPOSITION FOR KERATINIC FIBERS, PARTICULARLY FOR HUMAN HAIRS, BASED ON HALOGENATED NITROANILINES, DYEING METHOD USING THE TINCTORIAL COMPOSITION AND NEW HALOGENATED 2-NITROANILINES USED THEREOF

摘要

The invention relates to a dyeing composition for keratin fibers, and in particular for human hair, characterized in that it contains, in a solvent medium, at least one halogenated 2-nitroaniline of formula: ## STR2 ## In which Y denotes a halogen atom when Z denotes the group NHR 2 and Y denotes a hydrogen atom, when Z denotes a halogen atom and wherein R denotes a halogen atom and R 2, which are identical or different, denote a hydrogen atom, an alkyl group, mono- or polyhydroxylated alkyl, alkyl substituted with an alkoxy or hydroxyalkoxy group, aminoalkyl whose amino group may be optionally substituted with one or two alkyl or hydroxyalkyl groups, the nitrogen atom of the aminoalkyl group may also be part of a heterocycle, the alkyl radicals having 1 to 6 carbon atoms, or a cosmetically acceptable salt of a compound of formula I comprising a salifiable amine anion, which can be used for direct dyeing or oxidation, as well as compounds of formula: ## STR3 ## in which R 1 and R 2 do not simultaneously denote H and compounds of formula: embedded image in which R '1 denotes polyhydroxy alkyl, alkyl substituted by alkoxy or hydroxyalkoxy, aminoalkyl of which the amino group may be substituted by 1 or 2; alkyl or hydroxyalkyl or form a heterocycle. / P
