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.

The invention relates to the dyeing of keratin fibres using azomethine direct dyes or reduced precursors of azomethine direct dyes of formula (I) and (II) obtained from 2-amino-3-hydroxypyridine. The invention relates to a dye composition comprising at least one azomethine direct dye or a reduced precursor of an azomethine direct dye, to a process for dyeing keratin fibres, using the said composition, and to their uses in the dyeing of keratin fibres. This composition allows a particularly stable and fast coloration to be obtained.
摘要:
The present disclosure relates to a novel family of N-heteroaryl secondary para-phenylenediamines, to their preparation, to their use for dyeing the hair and to a dye composition for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising, in a suitable dyeing medium, at least one heteroaryl secondary para-phenylenediamine. The disclosure also relates to the process using this composition, to its use and to the multi-compartment device and dyeing “kit”.
摘要:
Disclosed herein is a novel family of double para-phenylenediamines joined by a linker arm comprising at least one substituent chosen from hydroxyl, alkoxy, and/or amino substituents. Also disclosed herein is a dyeing composition comprising, in a medium suitable for dyeing, at least one para-phenylenediamine joined by a linker arm comprising at least one substituent chosen from hydroxyl, alkoxy, and/or amino substituents. Further disclosed herein is a method for dyeing keratin fibers comprising applying such a dyeing composition to the keratin fibers. A multi-compartment kit comprising at least one dyeing composition of the present disclosure and at least one oxidizing composition is also disclosed herein.
