摘要:
The present disclosure relates to novel secondary para-phenylenediamine compounds comprising N-alkylfluorine, to a process for preparing them, to a composition for dyeing keratin fibers, for example human keratin fibers such as the hair, comprising, in a medium that is suitable for dyeing, at least one secondary para-phenylenediamine compound comprising N-alkylfluorine as disclosed, to a process for dyeing keratin fibers with the disclosed compositions, and also to a dyeing “kit” comprising the dyeing compositions.
摘要:
The invention relates to the dyeing of keratinous fibres using azomethine direct dyes of formula (I) or reduced precursors of azomethine direct dyes of formula (II) obtained from 2-chloro-3-amino-6-methylphenol. A subject-matter of the invention is a dyeing composition comprising at least one chlorinated azomethine direct dye or one reduced precursor of a chlorinated azomethine direct dye, a method for dyeing keratinous fibres which employs the said composition and their uses in the dyeing of keratinous fibres. This composition makes it possible to obtain a particularly stable and consistent colouring.
摘要:
The present disclosure relates to double secondary para-phenylenediamine dye compounds. The present disclosure further relates to a dye composition comprising at least one double secondary para-phenylenediamine compound, a process for dyeing keratin fibers using the composition, and a kit for dyeing keratin fibers comprising a separate composition comprising an oxidizing agent.
摘要:
The present disclosure relates to a novel family of sulfur-containing secondary para-phenylenediamines, to processes for preparing them, to compositions for dyeing keratin fibers, for example keratin fibers such as the hair, comprising, in a suitable dyeing medium, at least such one sulfur-containing secondary para-phenylenediamine. The present disclosure also relates to processes for dyeing keratin fibers with the compositions according to the present disclosure and to multi-compartment dyeing kits containing such compositions.
