## Background
This application claims benefit of U.S. Provisional Application No. 60/841,235, filed Aug. 31, 2006, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. § 119 to French Patent Application No. FR 06/07247, filed Aug. 10, 2006, the contents of which are also incorporated herein by reference.


Disclosed herein is a composition for the oxidation dyeing of keratinous fibers, for example, human keratinous fibers, such as the hair, comprising, in a medium appropriate for dyeing, at least one oxidation dye and at least one specific amphoteric polymer described below.
It is known to dye keratinous fibers such as human hair with dyeing compositions comprising oxidation dyes, such as oxidation dye precursors and coloring modifiers.
Oxidation dye precursors, generally known as oxidation bases, are initially colorless or weakly colored compounds which, in combination with oxidizing products, can give rise, by an oxidative coupling process, to colored and coloring compounds. These may be, for example, compounds such as ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic bases.
It is also known that it is possible to vary the shades obtained with these oxidation bases by combining them with couplers or coloring modifiers, the latter may be chosen from, for example, meta-diaminobenzenes, meta-aminophenols, meta-diphenols and certain heterocyclic compounds, such as indole compounds.
The variety of the molecules involved as oxidation bases and couplers makes it possible to obtain a rich pallet of colors.
The “permanent” coloring obtained by virtue of these oxidation dyes, also known as oxidation coloring, furthermore has to satisfy a certain number of criteria. For example, it must not be toxic, it should make it possible to obtain shades with the desired intensity, and it should behave well in the face of external agents, such as light, bad weather, washing, permanent waving, perspiration and rubbing.
The dyes should also make it possible to cover white hair and, finally, be as nonselective as possible, that is to say make it possible to obtain the smallest possible differences in coloring along the same keratinous fiber, which may be differently sensitized (that is to say, damaged) between its tip and its root.
European Patent Application EP 1 048 290 describes a composition for the oxidation dyeing of the hair comprising an oxidation dye precursor, a coupler and an amphoteric polymer comprising repeat units (a) of acrylic acid and (b) of a cationic monomer chosen from methacrylamidopropyltrimethylammonium chloride, dimethyldiallylammonium chloride and their mixtures, the molar ratio of the units (a) to the units (b) being greater than or equal to 1⁄3. This composition can make it possible to improve the deposition of the dyes on the hairs and thus to render the dye more effective.
United States Patent Application Publication No. 2005/0015895 describes a composition for the oxidation dyeing of the hair comprising an oxidation dye and a quaternary amphoteric terpolymer comprising the following repeat units: (a) methacrylamidopropyltrimethylammonium chloride or dimethyldiallylammonium chloride (b) acrylic acid or sodium methacrylate, and (c) acrylamide, with an (a)/(b) ratio of greater than or equal to 4. This composition can make it possible to obtain a better conditioning effect on hair fibers.
Finally, French Patent No. FR 2 817 467 describes a composition for the oxidation dyeing of keratinous fibers comprising an oxidation dye, an associative polymer and a polymer comprising units derived from a monomer of (i) acrylamide, (ii) dialkyldiallylammonium halide and (iii) vinylcarboxylic acid type. This composition can make it possible to obtain an optimum application to the fibers, for example it can form a composition that does not run, without, however, detrimentally affecting the qualities of the coloring.
However, the oxidation dyeing compositions of the prior art are often difficult to employ. For instance, after a more or less lengthy leave-in time, the composition applied to the hair has to be removed by rinsing and this rinsing stage is often lengthy and difficult, the product being difficult to remove.
Accordingly, there is a need in the art for novel compositions for the oxidation dyeing of keratinous fibers, which do not exhibit the disadvantages of the prior art. Thus, the present disclosure relates to dyeing compositions which are easier and faster to remove but which nevertheless remain easy to apply (for example, which do not run, and remain highly localized at the point of application), without, however, detrimentally affecting the strength, the chromaticity, and the selectivity of the coloring.
Disclosed herein is a composition for the oxidation dyeing of keratinous fibers, for example, human keratinous fibers, such as the hair, comprising, in a medium appropriate for dyeing, at least one oxidation dye and at least one amphoteric polymer comprising the repetition of:

    
    
        (i) at least one unit derived from a monomer of acrylamide type,
        (ii) at least one unit derived from a monomer of dialkyldiallylammonium halide type, and
        (iii) at least 50 mol % of at least one units derived from a monomer of vinylcarboxylic acid type.
    
    


The composition disclosed herein can be easily and rapidly removed during the rinsing stage while retaining good rheological properties. In addition, it can make it possible to improve the cosmetic properties of the hair, such as disentangling and smoothing.
Finally, the dyeing properties of this composition can be highly satisfactory, both as regards the selectivity and the intensity of the coloring obtained.
The present disclosure further relates to a method for dyeing keratinous fibers employing the composition disclosed herein.
The present disclosure also relates to a multicompartment device for the implementation of the method disclosed herein.
The present disclosure further relates to the use, for the oxidation dyeing of keratinous fibers, of the composition as disclosed herein.

Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.
In these examples, all the amounts are shown as percent by weight of active material (A.M.), with respect to the total weight of the composition, unless otherwise indicated. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the present disclosure are approximations, the numerical values set forth in the specific example are reported as precisely as possible. Any numerical values, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
The following examples are intended to illustrate the present disclosure in a non-limiting manner.

Each of the compositions A and B was mixed, in a 1+1.5 ratio by weight, with an oxidizing composition having a hydrogen peroxide content of 20 volumes.
The pH values of the mixtures thus obtained was 10.
These mixtures were applied to grey hair comprising 90% of white hairs for a leave-in time of 30 minutes at ambient temperature.
The hair was subsequently rinsed, washed with standard shampoo, then rinsed with water and dried.
Using the two compositions as disclose above, a shade with an attractive coppery red highlight possessing good persistence was obtained in the two cases.
It was observed that the composition resulting from the mixture of inventive composition B with the oxidizing composition was more easily rinsed than that obtained with comparative composition A.
In addition, after coloring with inventive composition B, it was observed that the hair was particularly smooth.
