Definitions
- Triaromatic azomethine direct dyes dye composition comprising at least one such dye, method of implementation and use
- the present invention relates to particular triaromatic direct dyes of azomethine type and also to the use thereof for dyeing keratin fibres, in particular human keratin fibres such as the hair.
- the invention also relates to a composition for dyeing keratin fibres comprising, in a medium suitable for dyeing, such direct dyes and also to a method for dyeing using said composition.
- a final subj ect of the invention is the precursors of these direct dyes, the use thereof for dyeing fibres and a multicompartment device containing them.
- the present invention relates to the field of dyeing keratin fibres and more particularly to the field o f hair dyeing.
- the method conventionally used in direct dyeing consists in applying to the keratin fibres one or more direct dyes, or colouring mo lecules, which have an affinity for said fibres, leaving them on for a time, and then rinsing the fibres.
- the direct dyes used hitherto are generally nitrobenzene dyes, anthraquinone dyes, nitropyridine dyes, dyes o f azo, xanthene, acridine or azine type or triarylmethane-type dyes.
- These direct dyes may also be applied to the keratin fibres in the presence of an oxidizing agent if it is desired to obtain a simultaneous fibre-lightening effect.
- the co lours that result therefrom are temporary or semi-permanent colours since the nature of the interactions that bind the direct dyes to the keratin fibre and their desorption from the surface and/or the core of the fibre are responsible for their weak dyeing power and their poor fastness with respect to washing, inclement weather or perspiration.
- direct dyes are generally sensitive to the action of oxidizing agents, which makes them difficult to use in particular in lightening direct dye compositions that are formulated from aqueous hydrogen peroxide solution and an alkalinizing agent, which are similar to compositions used for oxidation dyeing.
- direct dyes are generally not very compatible with dye compositions intended to lighten the fibres and, consequently, using them in a lightening dyeing method, as an alternative to oxidation dyeing, is not yet entirely satisfactory.
- azomethine-type direct dyes having a triaromatic unit o f formula (I) below, the organic or inorganic acid or base salts thereo f, the tautomeric, optical isomer or geometric isomer forms thereof and/or the solvates thereof:
- ni and n 2 represent, independently o f one another, an integer equal to 0, 1 , 2 , 3 or 4;

- the direct dyes according to the invention enable the keratin fibres to be dyed satisfactorily, especially by resulting in powerful, chromatic and sparingly selective colours and lead to an improved uptake of the colouration.
- the direct dyes according to the invention are light-stable and can be used in the presence o f an oxidizing agent, which facilitates their use in lightening direct dye compositions based on oxidizing agents .
- the direct dyes according to the present invention lead to long-lasting co lours and are compatible with dye compositions that are intended to lighten keratin fibres.
- one subject of the invention is colourless or weakly coloured leuco-type compounds, which correspond to the reduced form of the azomethine-type direct dyes having a triaromatic unit according to the invention, of formula (III) below:
- the leuco-type compounds according to the invention may therefore lead, in the presence of one or more oxidizing agents, to azomethine-type direct dyes of formula (I).
- the invention also relates to the use of one or more leuco-type compounds of formula (III) as precursors of the direct dyes of formula (I).
- the invention relates to the use of one or more leuco-type compounds of formula (III) in the presence of one or more oxidizing agents for dyeing keratin fibres, especially human keratin fibres such as the hair.

Description
Triaromatic azomethine direct dyes, dye composition comprising at least one such dye, method of implementation and use
The present invention relates to particular triaromatic direct dyes of azomethine type and also to the use thereof for dyeing keratin fibres, in particular human keratin fibres such as the hair.
The invention also relates to a composition for dyeing keratin fibres comprising, in a medium suitable for dyeing, such direct dyes and also to a method for dyeing using said composition.
A final subj ect of the invention is the precursors of these direct dyes, the use thereof for dyeing fibres and a multicompartment device containing them.
The present invention relates to the field of dyeing keratin fibres and more particularly to the field o f hair dyeing.
It is known practice to dye keratin fibres, and in particular the hair, with dye compositions containing one or more direct dyes, according to a "direct dyeing" method.
The method conventionally used in direct dyeing consists in applying to the keratin fibres one or more direct dyes, or colouring mo lecules, which have an affinity for said fibres, leaving them on for a time, and then rinsing the fibres. The direct dyes used hitherto are generally nitrobenzene dyes, anthraquinone dyes, nitropyridine dyes, dyes o f azo, xanthene, acridine or azine type or triarylmethane-type dyes.
These direct dyes may also be applied to the keratin fibres in the presence of an oxidizing agent if it is desired to obtain a simultaneous fibre-lightening effect.
However, the co lours that result therefrom are temporary or semi-permanent colours since the nature of the interactions that bind the direct dyes to the keratin fibre and their desorption from the surface and/or the core of the fibre are responsible for their weak dyeing power and their poor fastness with respect to washing, inclement weather or perspiration.
Furthermore, such direct dyes are generally sensitive to the action of oxidizing agents, which makes them difficult to use in
particular in lightening direct dye compositions that are formulated from aqueous hydrogen peroxide solution and an alkalinizing agent, which are similar to compositions used for oxidation dyeing. In other words, direct dyes are generally not very compatible with dye compositions intended to lighten the fibres and, consequently, using them in a lightening dyeing method, as an alternative to oxidation dyeing, is not yet entirely satisfactory.
These dyes also have the drawback of lacking light stability, due to the low resistance of the chromophore to photochemical attacks, which tends to lead to the colour of the keratin fibres fading over time.
Therefore there is a real need to have direct dyes that not only enable the keratin fibres to be dyed satisfactorily but that are also light-stable, capable of resulting in co lours that resist the various attacks that the fibres may be subj ected to, such as inclement weather, washing and perspiration, and further, that are sufficiently stable in the presence of oxidizing agents such as aqueous hydrogen peroxide so lution to be able to deliver simultaneous lightening of the fibre with the advantages set out hereinabove.
These obj ectives are achieved with the present invention, which relates in particular to azomethine-type direct dyes having a triaromatic unit o f formula (I) below, the organic or inorganic acid or base salts thereo f, the tautomeric, optical isomer or geometric isomer forms thereof and/or the solvates thereof:

In particular, the invention also relates to the use of said dye composition for co louring keratin fibres, especially human keratin fibres such as the hair.
The present invention also relates to the use, for dyeing keratin fibres, in particular human keratin fibres such as the hair, of one or more azomethine-type dyes having a triaromatic unit o f formula (I) below, the organic or inorganic acid or base salts thereof, the tautomeric, optical isomer or geometric isomer forms thereof and/or the so lvates thereo f:
in which formula (I) nl s n2, R, Ri , R2, R3 , R4, i and X2 have the same meanings as those indicated previously.
The invention additionally relates to a method for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which applied to said fibres is a dye composition comprising, in a medium suitable for dyeing, one or more azomethine-type dyes having a triaromatic unit o f formula (I) below, the organic or inorganic acid or base salts thereof, the tautomeric, optical isomer or geometric isomer forms thereo f and/or the so lvates thereo f:
in which formula (I) nl s n2, R, Rl s R2, R3 , R4, Xi and X2 have the same meanings as those indicated previously ; for a time sufficient to obtain the desired coloration, after which the fibres are rinsed, optionally washed with shampoo, rinsed again and the resulting fibres are dried or left to dry.
Similarly, the invention relates more particularly to a method for lightening keratin fibres, especially human keratin fibres such as the hair, in which applied to said fibres are (i) a dye composition free
of oxidizing agent and comprising, in a medium suitable for dyeing, one or more azomethine-type dyes having a triaromatic unit of formula (I) below, the organic or inorganic acid or base salts thereof, the tautomeric, optical isomer or geometric isomer forms thereof and/or the so lvates thereo f:

The azomethine-type direct dyes having a triaromatic unit o f formula (I) according to the invention thus make it possible to result in co lours that resist the various attacks that the keratin fibres may be subj ect to, such as inclement weather, light, washing and perspiration.
Furthermore, the direct dyes according to the invention enable the keratin fibres to be dyed satisfactorily, especially by resulting in powerful, chromatic and sparingly selective colours and lead to an improved uptake of the colouration.
The direct dyes according to the invention are light-stable and can be used in the presence o f an oxidizing agent, which facilitates their use in lightening direct dye compositions based on oxidizing agents .
In other words, the direct dyes according to the present invention lead to long-lasting co lours and are compatible with dye compositions that are intended to lighten keratin fibres.
Furthermore, one subject of the invention is colourless or weakly coloured leuco-type compounds, which correspond to the reduced form of the azomethine-type direct dyes having a triaromatic unit according to the invention, of formula (III) below:

and the organic or inorganic acid or base salts thereof, the tautomeric, optical isomer or geometric isomer forms thereof and/or the solvates thereof;
in which formula (III) nls n2, R, Ri, R2, R3, R4, i and X2 have the same meanings as those indicated previously in formula (I).
The leuco-type compounds according to the invention may therefore lead, in the presence of one or more oxidizing agents, to azomethine-type direct dyes of formula (I).
Thus, the invention also relates to the use of one or more leuco-type compounds of formula (III) as precursors of the direct dyes of formula (I).
In particular, the invention relates to the use of one or more leuco-type compounds of formula (III) in the presence of one or more oxidizing agents for dyeing keratin fibres, especially human keratin fibres such as the hair.
The invention also relates to a multicompartment device or kit containing a first compartment comprising one or more leuco-type compounds of formula (III) as defined previously and a second compartment comprising one or more oxidizing agents.
The leuco-type compounds of formula (III) used under oxidizing conditions thus have the advantage of resulting in colours that resist the various attacks that the keratin fibres may be subjected to, such as inclement weather, washing, light or perspiration.

Preferably, the oxidizing agent is used separately in a cosmetic composition.
Thus, the present invention also relates to a method for lightening keratin fibres, in particular human keratin fibres such as the hair, in which applied to said fibres are (i) the dye composition as defined previously free of oxidizing agent and (ii) a cosmetic composition comprising one or more oxidizing agents; compositions (i) and (ii) being applied to said keratin fibres sequentially or simultaneously for a time sufficient to obtain the desired lightening, after which the fibres are rinsed, optionally washed with shampoo, rinsed again and the resulting fibres are dried or left to dry.

The leuco-type compounds corresponding to formula (III) are generally obtained by reacting the azomethine-type compounds of
formula (I) with a reducing agent according to the reaction scheme below :
Synthesis approaches similar to this reaction scheme are described in patent applications FR 2 056 799, FR 2 047 932, FR 2 165 965 and FR 2 262 023.

Preferably, the leuco-type compounds of formula (III) are selected from the compounds corresponding to the reduced form of the azomethine-type direct dyes 1 to 82 mentioned previously.
In other words, the leuco-type compounds of formula (III) are selected from the precursors of azomethine-type direct dyes 1 to 82.
More preferably still, the leuco-type compounds of formula
(III) are selected from the precursors of direct dyes 1 , 4, 6, 16, 20, 28 , 29 and 30.

The oxidizing agent may be atmospheric oxygen or may be selected from the aforementioned oxidizing agents.
In particular, when the oxidizing agent is atmospheric oxygen, simply exposing the keratin fibres treated with the composition comprising the leuco-type compound(s) to air makes it possible to generate the colouring species and, consequently, to colour the fibres .
According to one variant, the oxidizing agent(s) may be applied to the keratin fibres simultaneously with or sequentially to the cosmetic composition comprising the leuco-type compounds .
Thus, the cosmetic composition comprising the oxidizing agent(s) may be applied to the keratin fibres before, simultaneously with or after the cosmetic composition comprising the leuco-type compounds o f formula (III) according to the invention.
According to another variant, a ready-to-use composition that results from the mixing of a cosmetic composition comprising one or more leuco-type compounds of the aforementioned formula (III) and o f a cosmetic composition comprising one or more oxidizing agents is applied to keratin fibres.
The ready-to-use composition which is thus applied to the keratin fibres may be in a variety o f forms, such as in the form o f liquids, creams or gels or in any other form appropriate for dyeing keratin fibres, and in particular human hair.
The leave-on time o f the composition(s) varies from 1 to 60 minutes, preferably from 5 to 40 minutes and more preferably from 10 to 30 minutes.
The cosmetic composition comprising such leuco-type compounds is generally applied to the keratin fibres at ambient temperature, preferably between 25 °C and 55 °C .

VI. Dyeing device
The present invention also relates to a multicompartment device or "kit" comprising a first compartment containing a cosmetic composition comprising one or more dyes of formula (I) as defined previously or containing one or more leuco-type compounds of formula (III) as defined previously, and optionally a second compartment comprising one or more oxidizing agents .

More particularly, the invention relates to a multicompartment dyeing device or kit comprising a first compartment containing a cosmetic composition comprising one or more direct dyes of the aforementioned formula (I) free o f oxidizing agent and a second compartment containing a cosmetic composition comprising one or more oxidizing agents .
The invention also relates to a multicompartment dyeing device or kit comprising a first compartment containing a cosmetic composition comprising one or more leuco-type compounds of the aforementioned formula (III), and a second compartment containing a cosmetic composition comprising one or more oxidizing agents .
According to one particular embodiment, the device may comprise at least one compartment comprising a cosmetic composition comprising one or more leuco-type compounds o f the aforementioned formula (III) .
In this case, the composition comprising the leuco-type compound(s) as defined above is applied to the keratin fibres that are co loured by means o f the exposure thereof to air.
The devices mentioned above are suitable for dyeing keratin fibres.
The evaluation o f the co loration can be done visually or read on a spectrocolorimeter (such as Minolta CM3600d, illuminant D65 , angle 10° , SCI values) for the L*, a*, b* colorimetric measurements . In this L*, a*, b* system, L* represents the intensity o f the co lor, a* indicates the green/red co lor axis and b indicates the blue/yellow co lor axis. The lower the value of L, the darker or more intense the co lor is. The higher the value of a , the redder the shade is; the higher the value o f b , the yellower the shade is.
The variation in co loring between the co lored locks of natural white hair which is untreated (control) and after treatment or co loration is defined by ΔΕ , corresponding to the colour uptake on keratin fibers, according to the fo llowing equation:
ΔΕ * = - ( L*— Lo * )2 + ( a*— a0 * f + ( b* - b0 * )2 (i)
In this equation, L*, a* and b* represent the values measured after dyeing the natural hair comprising 90% of white hairs and Lo , ao and bo represent the values measured for the untreated natural hair comprising 90% of white hairs.
The greater the value of ΔΕ, the greater the difference in color between the control lo cks and the dyed locks and the greater color uptake is . Chromaticity in the CIE L * , a* , b * colorimetric system is calculated according to the fo llowing equation:
C* = Va*2 + b*2
The greater the value of C * , the greater the chromaticity is.
The examples that follow serve to illustrate the invention without, however, being limiting in nature.
