## Background
This application claims benefit of U.S. Provisional Application No. 60/841,238, 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 06/07244, filed Aug. 10, 2006, the contents of which are also incorporated herein by reference.


Disclosed herein is a composition for the oxidation dyeing of keratin fibers, for example, of human keratin fibers such as the hair, comprising, in a medium that is suitable for dyeing, at least one oxidation dye and at least one particular amphoteric polymer described below.
It is known practice to dye keratin fibers such as human hair with dyeing compositions containing oxidation dyes, such as oxidation dye precursors and coloration modifiers.
Oxidation dye precursors, which are known as oxidation bases, are compounds that are initially colorless or weakly colored, which, when combined with oxidizing products, may give rise to colored compounds and dyes via a process of oxidative condensation. They may be, for example, compounds such as ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic bases.
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, for example, from meta-diaminobenzenes, meta-aminophenols, meta-diphenols and certain heterocyclic compounds such as indole compounds.
The variety of molecules used as oxidation bases and couplers allows a wide range of colors to be obtained.
The “permanent” coloration obtained by virtue of these oxidation dyes, which is also known as oxidation dyeing, should moreover satisfy certain criteria. For example, it should not have toxicological drawbacks, it should be able to produce shades in the desired intensity and it should show good resistance to external agents such as light, bad weather, washing, permanent-waving, perspiration and rubbing.
The dyes should also allow grey hair to be covered and, finally, they should be as unselective as possible, i.e. they should produce the smallest possible coloration differences along the same keratin fiber, which may be differently sensitized (i.e. damaged) between its end and its root.
European Patent Application No. 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 repeating units (a) of acrylic acid and (b) of a cationic monomer chosen from methacrylamidopropyltrimethylammonium chloride and dimethyldiallylammonium chloride, and mixtures thereof, the molar ratio between the units (a) and 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 hair and thus render the dyeing 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 repeating units: (a) methacrylamidopropyltrimethylammonium chloride or dimethyldiallylammonium chloride, (b) acrylic acid or sodium methacrylate, and (c) acrylamide, with a ratio (a)/(b) of greater than or equal to 4. This composition can make it possible to produce a better conditioning effect on hair fibers.
Finally, French Patent No. FR 2 817 467 describes a composition for the oxidation dyeing of keratin fibers, comprising an oxidation dye, an associative polymer and a polymer containing units derived from a monomer of (i) acrylamide, (ii) dialkyldiallylammonium halide, and (iii) vinylcarboxylic acid type. This composition can allow for optimum application on the fibers, for example does not run, without, however, impairing the coloring qualities.
However, the oxidation dyeing compositions of the prior art have certain drawbacks. For instance, their use is liable to lead to the phenomenon of static electricity at the surface of the keratin fibers, or of increasing such a phenomenon.
Accordingly, there is a heed in the art for novel compositions for the oxidation dyeing of keratin fibers, that do not have the drawbacks of the prior art. Thus, the present disclosure relates to oxidation dyeing compositions that can reduce the phenomenon of static electricity after dyeing.
Accordingly, disclosed herein is a composition for the oxidation dyeing of keratin fibers, for example, human keratin fibers such as the hair, comprising, in a medium that is suitable for dyeing, at least one oxidation dye and at least one amphoteric polymer comprising a repetition of:

    
    
        (i) from 45 mol % to 60 mol % of 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 one unit derived from a monomer of vinylcarboxylic acid type, wherein the mole ratio of the amount of the at least one unit derived from a monomer of dialkyldiallylammonium halide type to the amount of the at least one unit derived from a monomer of vinylcarboxylic acid type of greater than or equal to 1.
    
    


The composition disclosed herein can make it possible to prevent or reduce the phenomenon of static electricity at the surface of the hair, while at the same time maintaining 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 very satisfactory, as regards both the selectivity and the intensity of the coloration obtained.
The present disclosure also relates to a process for dyeing keratin fibers, in which a composition as disclosed herein is applied to the keratin fibers, in the presence of at least one oxidizing agent, for a time that is sufficient to develop the desired coloration.
The present disclosure also relates to a multi-compartment device for the implementation of the process disclosed herein.
The present disclosure still further relates to the use of the composition disclosed herein for the oxidation dyeing of keratin fibers.

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 indicated as weight percentages of active material (AM) relative 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 examples that follow are intended to illustrate the present disclosure without, however, limiting its scope.

Each of the compositions A and B was mixed in a 1+1.5 weight ratio with an oxidizing composition having a hydrogen peroxide titre of 20 volumes.
The pHs of the mixtures thus obtained were 10.
These mixtures were applied to grey hair containing 90% white hairs, for a leave-on time of 30 minutes at room temperature.
The hair was then rinsed, washed with a standard shampoo, rinsed with water and then dried.
An aesthetic red shade with a coppery tint, which shows good fastness, was obtained with the mixtures derived from compositions A and B with the oxidizing composition.
It was observed that the mixture derived from composition B with the oxidizing composition generates less static electricity at the surface of the treated hair than that obtained with composition A.
In addition, after dyeing with the mixture derived from composition B, it was observed that the hair was particularly smooth.
