ence.
This application claims benefit of U.S. Provisional Appli-
cation No. 60/638,110 filed Dec. 23, 2004, the contents of
which are incorporated herein by reference. This application
also claims benefit of priority under 35 U.S.C. §1 19 to French
Patent Application No. 04 10800, filed Oct. 13, 2004, the
contents of which are also incorporated by reference.
The present disclosure relates to a composition for color-
ing/dyeing keratin materials, for instance keratin fibers such
as the hair, comprising at least one pigment and at least one
particular electrophilic monomer, and a process for dyeing
keratin materials using this composition.
Within the field of coloring keratin fibers it is already
known to color keratin fibers by a variety of techniques,
starting from direct dyes or pigments, for non-permanent
colorations, or from dye precursors, for permanent colora-
tions.
Non-permanent coloration or direct coloration involves
dyeing the keratin fibers with dyeing compositions contain-
ing direct dyes. These dyes are colored, and coloring mol-
ecules which have an affinity for the keratin fibers. They are
applied to the keratin fibers for a time required for the desired
coloration to be obtained, then rinsed off.
The conventional dyes which are used include, for
example, dyes of the nitrobenzene, anthraquinone, nitropyri-
dine, azo, xanthene, acridine, azine or triarylmethane type or
natural dyes.
Some of these dyes can be used under lightening condi-
tions, allowing colorations to be obtained which are visible on
dark hair.
It is also known to dye keratin fibers permanently by oxi-
dation coloring. This coloring technique involves applying to
the keratin fibers a composition containing dye precursors
such as oxidation bases and couplers. These precursors, under
the action of an oxidant, will form at least one colored species
in the hair.
The variety of molecules employed as oxidation bases and
couplers can make it possible to obtain a rich palette of colors,
and the colorations resulting from them can be permanent,
powerful, and/ or resistant to external agents, in particular to
light, inclement weather, washing, perspiration, and rubbing.
In order to be visible on dark hair, the colorations resulting
from these two coloring techniques require a prior or simul-
taneous bleaching of the keratin fibers. This bleaching step,
carried out with an oxidant such as hydrogen peroxide or
persalts, can entail a not inconsiderable amount of degrada-
tion of the keratin fibers, which may impair their cosmetic
properties. The hair then has a tendency to become rough, less
easy to disentangle, and/or more fragile.
Another method of coloring keratin fibers involves using
pigments. In effect, the use of a pigment at the surface of the
keratin fibers makes it possible, generally speaking, to obtain
colorations which are visible on dark hair, since the surface
pigment masks the natural color of the fiber. The use of
pigments for coloring keratin fibers is described, for example,
in French Patent Application Publication No. FR 2 741 530,

which recommends the use, for the coloring of the keratin
fibers, of a composition comprising at least one dispersion of
particles of film-forrning polymer comprising at least one
acid functional group, and at least one pigment dispersed in
the continuous phase of said dispersion.
The coloration obtained by this mode of coloring can have
the drawback of having a low level of resistance to shampoo-
ing.
French Patent Application Publication No. FR 2 833 489
discloses hair treatment compositions on the basis of compo-
sitions comprising electrophilic monomers. A composition of
this kind can make it possible to obtain hair which is
extremely well coated and not greasy.
The present disclosure, therefore, relates to new composi-
tions for coloring or dyeing keratin materials, for instance
keratin fibers such as the hair, which make it possible to obtain
colorations which are visible on dark hair, without the need to
lighten or bleach the fibers, and/or which may exhibit good
resistance to sharnpooing.
Thus, in one embodiment, the present disclosure relates to
a process for dyeing keratin materials such as keratin fibers
comprising applying to the fibers a dyeing composition com-
prising, in a suitable dyeing medium, at least one pigment and
at least one electrophilic cyanoacrylate monomer of formula
(1)
(1)
CN
HZC
COO—R
in which R is chosen from alkyl radicals and alkoxyalkyl
radicals.
The present disclosure also relates to a composition com-
prising, in a suitable dyeing medium, at least one pigment in
an amount greater than 5% (w/w) by weight and at least one
cyanoacrylate electrophilic monomer of formula (I).
The process in accordance with the present disclosure can
make it possible to obtain a visible coloration on a dark
keratin material. For example, in the case of dark keratin
fibers, a highly visible coloration is obtained with no need to
lighten or bleach the keratin fibers and hence it is possible to
obtain a visible coloration on a dark keratin material without
risking physical degradation of the keratin fibers. Moreover,
this coloration exhibits good resistance to the various aggres-
sive influences to which the hair may be subjected, such as
shampooing, rubbing, light, inclement weather, perspiration,
and permanent reshaping (“perming”). In at least one
embodiment, the coloration shows good resistance to sham-

As used herein, the term “special-effect pigments” is
understood to mean pigments which create, generally speak-
ing, a colored appearance (characterized by a certain shade, a
certain liveliness and a certain lightness) which is not uniform
and which changes as a function of the conditions of obser-
vation (e.g., light, temperature, viewing angles, etc.). They
are consequently in contrast to white or colored pigments,
which provide a conventional opaque, semi-transparent or
transparent, uniform hue.
Non-limiting examples of special-effect pigments include
white nacreous pigments such as mica coated with titanium or
withbismuth oxychloride, colored nacreous pigments such as
mica coated with titanium and iron oxides, mica coated with
titanium, and, for instance, Prussian Blue or chromium oxide,
mica coated with titanium and an organic pigment as defined
above, and also nacreous pigments based on bismuth oxy-
chloride. Nacreous pigments include the nacres Cellini, sold
by Engelhard (mica-TiO2-lake), Prestige, sold by Eckart
(mica-TiO2) and Colorona, sold by Merck (mica-TiO2—
Fe2O3).
Non-limiting mention may also be made of interference-
effect pigments not attached to a substrate, such as liquid
crystals (Helicones HC from Wacker), holographic interfer-
ence flakes (Geometric Pigments or Spectra f/x from Spec-
tratek). Special-effect pigments can also comprise fluores-
cent pigments, whether they be daylight-fluorescent
substances or substances which produce ultraviolet fluores-
cence, phosphorescent pigments, photochromic pigments,
thermochromic pigments, and quantum dots, sold for
example by the company Quantum Dots Corporation.
The quantum dots are luminescent semi-conductive nano-
particles capable of emitting, under excitation by light, radia-
tion having a wavelength ranging from 400 nm to 700 nm.
These nanoparticles are known from the literature. For
instance, they may be manufactured by the processes
described, for example, in U.S. Pat. No. 6,225,198 or 5,990,
479, in the publications cited therein, and also in the follow-
ing publications: Dabboussi B. O. et al “(CdSe)ZnS Core-
shell Quantum Dots: Synthesis and Characterisation of a Size

cent CdSe/CdS core/shell nanocrystals with Photostability
and Electronic Accessibility,” Joumal of the American
Chemical Society, Vol. 119, No. 30, pp 7019-7029.
The variety of pigments which can be used in the present
disclosure allows a rich palette of colors to be obtained, and
also certain optical effects, such as metallic and interference
effects.
According to one embodiment of the present disclosure,
the at least one pigment is chosen from colored pigments. As
used herein, the term “colored pigments” is understood to

The dyeing medium of the composition of the present
disclosure may also be in the form of an emulsion and/ or may
be encapsulated, the at least one electrophilic monomer being
maintained within an anhydrous medium until the moment of
use. When the dyeing medium is an emulsion, this emulsion
can comprise, for example, a disperse or continuous phase

of the present disclosure in an amount ranging from 10 ppm to
10% by weight, such as from 50 ppm to 5% by weight,
relative to the total weight of the composition.
The composition of the present disclosure may also com-
prise at least one polymer which does not exhibit any reac-
tivity with the at least one electrophilic cyanoacrylate mono-
mer, and which is capable of increasing the viscosity of the
composition. The increase in viscosity can make it possible to
reduce the polymerization rate of the cyanoacrylate mono-
mers. In order to do this it is possible to add to the composition
of the present disclosure, non-exhaustively, polymethyl
methacrylate (PMMA) or else cyanoacrylate-based copoly-
mers of the kind described in U.S. Pat. No. 6,224,622.
The composition of the present disclosure may also com-
prise at least one filler. As used herein, the term “filler” is
understood to mean, without limitation, colorless or white,
mineral or synthetic, lamellar or non-larnellar particles. The
at least one filler may be present in an amount ranging from
0% to 48% by weight, relative to the total weight of the
composition, for instance from 0.01% to 30% by weight, and
such as from 0.02% to 20% by weight. Non-limiting mention

The composition may also comprise at least one conven-
tional cosmetic adjuvant. Without limitation, mention may be
made of reductants, oxidants, fats, silicones, thickeners, soft-
eners, antifoarns, moisturizers, emollients, alkalifiers, elas-

perfumes, peptizers, preservatives, anionic, cationic, ampho-
teric, zwitterionic or nonionic surfactants, fixative or non-
fixative polymers, conditioning polymers, proteins, and vita-
mins.
The composition disclosed herein may also comprise at
least one metal powder or particle, such as particles or pow-
ders of aluminium and of copper.
These compositions may be present in a variety of forms,
such as lotions, sprays and mousses, and may be applied as a
shampoo or conditioner.
In the case of sprays, the composition of the present dis-
closure may comprise at least one propellant. The propellant
is composed of the compressed or liquefied gases which are

commonly employed for preparing aerosol compositions. For
example, the at least one propellant can be chosen from air,
carbon dioxide, compressed nitrogen or else a soluble gas
such as dimethyl ether, hydrocarbons which are halogenated
(e.g., fluorinated) or non-halogenated, and mixtures thereof.
The present disclosure also relates to a process comprising
applying the composition of the present disclosure to keratin
materials, for instance keratin fibers such as the hair, in the
presence of at least one nucleophile.
According to one embodiment of the process of the present
disclosure, the at least one nucleophile capable of initiating
the polymerization of the at least one cyanoacrylate monomer
may be applied to the keratin fibers beforehand. The at least
one nucleophile may be used in pure form, in solution, or in
the form of an emulsion, or may be encapsulated. It may also
be added to the anhydrous composition at the time of use, just
before application to the keratin fibers.
By way of non-limiting example, the at least one nucleo-
phile can be water. This water may be provided, for example,
by prior wetting of the keratin fibers. It may also be added
directly to the composition before application.
According to one embodiment, it is possible to modify the
polymerization kinetics by wetting the fibers beforehand by
means of an aqueous solution whose pH has been adjusted
using a base, an acid or an acid/base mixture. The acid and/or
the base may be inorganic or organic.
According to another embodiment, the process of the
present disclosure may be carried out in a number of steps
comprising applying a composition containing at least one
pigment to the fibers, and then applying a composition com-
prising the at least one electrophilic cyanoacrylate monomer
of formula (I), wherein the at least one nucleophile is present
in the composition comprising the pigment or in a separate
composition. According to this embodiment, the composition
comprising the at least one pigment can be, for example, an
aqueous solution of pigments, which allows the fiber to be
wetted and the polymerization to be initiated when the at least
one electrophilic cyanoacrylate monomer is applied.
According to the process of the present disclosure, another
embodiment comprises either applying the at least one elec-
trophilic cyanoacrylate monomer and the at least one pigment
from a single composition, or applying the at least one pig-
ment in a first phase and then the at least one electrophilic
cyanoacrylate monomer.
The process of the present disclosure may include addi-
tional, intermediate or final, steps, such as the application of
a cosmetic product, a rinsing step and/ or a drying step. Drying
may be carried out under a hood, with a hairdryer and/or with
a smoothing iron. For example, the application of the com-
positions in accordance with the present disclosure may be
followed by a rinsing operation.
It is also possible to carry out multiple applications of the
composition of the present disclosure, so as to obtain a super-
position of layers, to achieve specific properties of the deposit
in terms of chemical nature, mechanical strength, thickness,
appearance and/or feel.
In order to improve, among other things, the adhesion of
the poly(cyanoacrylate) formed in situ, the fiber may be pre-
treated with any types of polymer.
In order to modify the anionic polymerization kinetics it is
also possible to enhance the nucleophilicity of the fiber by
chemical conversion of the keratin fibers. By way of example,
non-limiting mention may be made of the reduction of the
disulfide bridges, of which the keratin is partly composed, to
thiols before the composition of the present disclosure is
applied. Non-exhaustively, mention may be made, as reduc-
tants of the disulfide bridges of which the keratin is partly

nium thioglycolate, thioglycerol, 2,5-dihydroxybenzoic acid,
diammonium dithioglycolate, strontium thioglycolate, cal-
cium thioglycolate, zinc formaldehyde-sulphoxylate, isooc-
tyl thioglycolate, dl-cysteine and monoethanolamine thio gly-
colate.
Application of the composition of the present disclosure
may also be preceded by a hair treatment, such as a direct or
oxidation coloring operation.
According to the present disclosure, the at least one elec-
trophilic cyanoacrylate monomer can be chosen from, for
example, monomers capable of undergoing polymerization
on the keratin fibers under cosmetically acceptable condi-
tions. For instance, the polymerization of the at least one
electrophilic cyanoacrylate monomer can take place at a tem-
perature less than or equal to 80° C., such as ranging from 10°
C. to 80° C., for example ranging from 20° C. to 80° C., which
does not prevent the application being finished by drying
under a hood, blow-drying or the passage of a flat iron or
curling tongs.
The present disclosure additionally relates to a coloring kit
comprising at least one first composition, which comprises at
least one pigment, and at least one second composition,
which comprises at least one electrophilic cyanoacrylate
monomer of formula (1) and, optionally, at least one third
composition, which comprises at least one nucleophile.
According to this embodiment, the at least one composition
comprising the at least one pigment is an aqueous composi-
tion and the at least one composition comprising the at least
one electrophilic cyanoacrylate monomer is an anhydrous
composition.
According to another embodiment, the kit comprises at
least one first, anhydrous composition, which comprises at
one pigment and at least one electrophilic cyanoacrylate
monomer, and at least one second composition, which com-
prises at least one nucleophile.
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 equiva-
lents to the scope of the claims, each numerical parameter
should be construed in light of the number of significant digits
and ordinary rounding approaches.
Notwithstanding that the numerical ranges and parameters
setting forth the broad scope of the disclosure are approxima-
tions, the numerical values set forth in the specific examples
are reported as precisely as possible. Any numerical value,
however, inherently contain certain errors necessarily result-
ing from the standard deviation found in their respective
testing measurements.
The non-limiting examples below make it possible to illus-
trate the present disclosure without, however, limiting its
scope.
