摘要：
Abstract "Process for the keratin fiber oxidation dye and multi-compartment device" The present invention relates to a process for the keratin fiber oxidation dye which implements: a) a pretreatment step on said fibers by application on said fibers of a cosmetic composition (b) comprising: i) at least one grease in an amount greater than or equal to 10% by weight relative to the total weight of the composition (b)； and ii) at least one metal catalyst； b) optionally a washing, drying and / or friction drying step； c) followed by a drying step by applying to said fibers a cosmetic composition (a) comprising: i) at least one oxidation base, preferably chosen from paraphenylenediamines, bis (phenyl) alkylenediamines, aminophenols, ortho-aminophenols, preferably heterocyclic bases comprising at least two nitrogen atoms, and their addition salts； ii) optionally at least one coupler； and iii) at least one chemical oxidizing agent. The dyeing process significantly improves the dyeing properties of the color, particularly in terms of selectivity, chromaticity, and color intensity and absorption. The use of a composition that is rich in fatty substances, ie, greater than 10%, and contains at least one catalyst pretreatment prior to oxidation dyeing, allows for a marked improvement in dyeing properties, in particular in terms of color absorption in keratin fibers, strength (intensity) and chromaticity and color selectivity.resumo “processo para a tintura de oxidação das fibras queratínicas e dispositivo com compartimentos múltiplos” a presente invenção trata de um processo para a tintura de oxidação das fibras queratínicas que implementa: a) uma etapa de pré-tratamento sobre as referidas fibras por aplicação sobre as referidas fibras de uma composição cosmética (b) que compreende: i) pelo menos uma substância graxa em uma quantidade superior ou igual a 10% em peso em relação ao peso total da composição (b)； e ii) pelo menos um catalisador metálico； b) opcionalmente uma etapa d
