DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a composition for the oxidation dyeing of keratin fibres, in particular human keratin fibres such as the hair, comprising at least one suitably selected oxidation base, at least one meta-aminophenol as first coupler and 4-hydroxyindoline and/or at least one of the addition salts thereof with an acid as second coupler, as well as to the dyeing process using this composition with an oxidizing agent.
It is known to dye keratin fibres, and in particular human hair, with dye compositions containing oxidation dye precursors, in particular ortho- or para-phenylenediamines, ortho- or para-aminophenols, which are generally referred to as oxidation bases. The oxidation dye precursors, or oxidation bases, are colourless or weakly coloured compounds which, when combined with oxidizing products, may give rise to coloured compounds and dyes by a process of oxidative condensation.
It is also known that the shades obtained with these oxidation bases may be varied by combining them with couplers or coloration modifiers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain indole or indoline compounds.
The variety of molecules used as oxidation bases and couplers makes it possible to obtain a wide range of colours.
The so-called "permanent" coloration obtained by means of these oxidation dyes must moreover satisfy a certain number of requirements. Thus, it must have no toxicological drawbacks and it must allow shades of the desired intensity to be obtained and have good resistance to external agents (light, bad weather, washing, permanent-waving, perspiration and rubbing).
The dyes must also allow white hairs to be covered and, lastly, they must be as unselective as possible, that is to say that they must allow the smallest possible differences in coloration to be produced over the entire length of the same keratin fibre, which may indeed be differently sensitized (i.e. damaged) between its tip and its root.
In order to produce natural or highlighted shades, it is common to use dye compositions comprising a para-phenylenediamine derivative as oxidation base and a meta-aminophenol derivative as coupler. However, the coloration obtained with such dye compositions are not entirely satisfactory since they generally have mediocre light-fastness.
Moreover, compositions for the oxidation dyeing of keratin fibres in alkaline medium, comprising at least one oxidation base such as, for example, para-phenylenediamine or a para-phenylenediamine derivative, in combination with an indoline coupler such as, for example, 4-hydroxyindoline, have already been proposed, in particular in patent application FR 2,008,797. These compositions are not entirely satisfactory either since they lead to colorations which also have mediocre light-fastness.
Now, the Applicant has just discovered that it is possible to obtain novel dyes in acidic, neutral or alkaline medium, which are capable of generating intense colorations that offer good resistance to the various attacking factors to which the hair may be subjected and in particular to the action of light, by combining at least one suitably selected oxidation base, at least one meta-aminophenol as first coupler and 4-hydroxyindoline and/or at least one of the addition salts thereof with an acid as second coupler. This result is all the more unexpected and surprising since, as indicated above, when the two couplers are used separately in combination with the same oxidation base in accordance with the invention, they lead to colorations with poor light-fastness on hair.
This discovery forms the basis of the present invention.
A first subject of the invention is thus a composition for the oxidation dyeing of keratin fibres, and in particular human keratin fibres such as the hair, characterized in that it comprises, in a medium which is suitable for dyeing: bis(phenyl)alkylenediamines, salts thereof with an acid.
The oxidation dyeing composition in accordance with the invention makes it possible to obtain intense c
