Description

The present invention relates to the field of makeup and is intended to create new makeup effects, especially on a keratin support such as skin, lips, nails, using a new makeup device.

This makeup device is characterized by the fact that it has a coating <B> to </ B> deposit on a keratinous support or on false nails or false eyelashes and a matrix <B> to </ B> micro reliefs arranged to form an optically variable image on said coating.

By optically variable image, one understands goniochromatic effects and / or effects of reliefs or volume (effects <B> 3D) </ B> and / or the appearance and the disappearance of elements, possibly juxtaposed in a way <B > to <B> to </ B> animation effects, depending on the viewing direction.

Thanks to the invention, it is possible to create on the skin, lips or nails, or on false nails or false eyelashes, aesthetically attractive effects and / or to hide imperfections such as such as wrinkles, fine lines, pimples, redness, rosacea or blackheads.

In particular, one can create a contrast effect to hide defect or divert the look of an imperfection.

The coating producing the optically variable image can still play the role of a fly.

In addition, the invention allows the creation of colors by a phenomenon of diffraction interferences, without the use of specific dyes or pigments, therefore without posing difficulties (compatibility, toxicology, regulation) encountered during the development of new compositions. having dyes or pigments. Thus, coating used can be without pigment or dye.

The use, in the invention, of a matrix to form the optically variable image offers great freedom in the choice of the coating on which this image is made.

Thus, the user can choose any suitable coating, for example varnish <B> to </ B> nails or a red <B> to </ B> lips of the desired color, available on the market.

The coating used may in particular be a peelable nail polish which can be removed without a solvent.

Advantageously, the makeup device according to the invention comprises a packaging and application device for applying a matrix coating layer, keratin support, false nails or false eyelashes. Advantageously, the matrix is constituted by a plastic film having micro-reliefs capable of producing an optically variable image. Unexpectedly, such a film is able to leave on the coating an optically variable image, and has the advantage of being able to be produced at a relatively low cost. Advantageously, the makeup device comprises a layer of a compressible material and a fixing tape, for example an adhesive tape, for immobilizing this layer with respect to the surface on which the optically variable image must be formed. . The layer of compressible material makes it possible to standardize the application pressure of the matrix on the coating and to obtain particularly satisfactory results. The layer of compressible material is advantageously fixed the face of the matrix which is opposite to that of the micro-reliefs intended to produce a variable image. The micro-reliefs advantageously constitute a diffraction grating. The optically variable image can produce a goniochromatic effect. The optically variable image can still produce a holographic effect. The invention also relates to the use of the aforementioned device for decorating a keratin support such as skin, lips or nails, or false nails <B> or </ B> false eyelashes. The invention also relates to the use of a device as mentioned above to create an optically variable image on a keratinous support or on false nails or false eyelashes, for example on the skin to hide local imperfections of the latter , to create a volume effect on the lips or to create an optical effect on the eyelashes or eyebrows. Another subject of the invention is the use of a master diffraction grating comprising micro-reliefs to form on a coating intended to be applied to a keratinous support, or to false or false nails. eyelashes, an optically variable image. The invention also relates to the use of a matrix <B> to </ B> micro reliefs to form on keratinous support or on false nails or false eyelashes an optically variable image. Coating used can be a nail polish, a red lip, a foundation, a mascara, a tattoo or a powder. The subject of the invention is also a method for producing an optically variable image on a keratinous support or false nails or false eyelashes, this method comprising the steps consisting of: <B> to: </ B> a) apply a coating on a matrix <B> to </ B> micro reliefs, <B> b) </ B> transfer the coating to the keratinous support or false nails or false eyelashes, leaving the matrix on the coating a footprint producing optically variable image. Advantageously, two layers of coating are successively applied to the matrix, the second layer being applied to the first layer after allowing the latter to dry, this second layer serving to ensure the adhesion of the </ B> the first on the keratin support or false nails or false eyelashes. The second layer may have a formulation chosen such that it causes drying cracking of the first layer, to induce additional aesthetic effect. The subject of the invention is also a process for producing, in situ on a keratinous support on false nails or false eyelashes, an optically variable image, this process comprising the steps of: <B> to: </ B> apply a coating on the said keratinous support or the false nails or false eyelashes <B> b) </ B> apply a matrix <B> to </ B> micro reliefs on the coating, c) remove the matrix leaving on the coating, the impression of the micro-reliefs of the matrix, this impression producing an optically variable image. Advantageously, after application of the coating, it is allowed to dry for a predetermined time before applying the matrix. This duration is for example between <B> 3 </ B> and <B> <I> 5 </ I> </ B> <I> mn. </ I>

The matrix may be immobilized on the coating by means of a fastening tape. Advantageously, there is interposed between the matrix and the fastening tape a layer of a compressible material such as foam or a sponge.

The subject of the invention is also a diffraction grating <B> with micro-reliefs producing an optically variable image, characterized in that this image is produced <I> in situ </ I> on a keratin support or false nails or false eyelashes.

The invention will be better understood by reading the following detailed description, by non-limiting examples of implementation, and by examining the attached drawing. where <B>: </ B> is <B> 1 </ B> is a schematic view of a device according to the invention, Figure 2 illustrates the application of the coating to the skin, figures <B> 3 </ B> and 4 illustrate the application of a holographic matrix on the coating deposited on the skin, to form <I> in situ </ I> an optically variable image, <B> - </ B> figure <B> 5 </ B> represents a device comprising a pressing member for controlling the application pressure of the matrix on the coating, the figure <B> 6 </ B> represents a device in which the roll-mounted holographic matrix, <B> - </ B> Figure <B> 7 </ B> represents a matrix on which a first coating layer has been deposited, <B> - </ B> Figure <B > 8 </ B> represents a matrix on which was deposited a second layer coating, after drying the first, <B> - </ B> <B> 9 </ B> illustrates the transfer of the coating and matrix on a fingernail, <B> - </ B > figure <B> 10 </ B> illustrates the removal of the matrix, <B> - </ B> the figure <B> Il </ B> represents an adhesive support provided with a layer of a compressible material and a matrix <B> to </ B> micro reliefs, <B> - </ B> Figure 12 is a section along XII-XII of Figure <B> 11, </ B> and <B> - </ B> Figures <B> 13 <I> to </ I> 15 </ B> illustrate the placement of the matrix on a fingernail. There is shown in Figure <B> 1 </ B> a <B> 1 </ B> make-up device <B> to </ B> first example of implementation of the invention. This device comprises on the one hand an application packaging device <B> 10 </ B> and on the other hand a matrix 20.

The application packer <B> 10 </ B> comprises a container <B> 1 </ B> containing a coating R <B> to </ B> in the liquid state and an applicator 12 provided <B> at one end of a gripping element also constituting a closing cap for container <B> 11 </ B> and <B> at </ B> the other end of an application element < B> 13 </ B> such as a felt, a brush or a flocked foam, to deposit on the skin, the lips or the nails, or the matrix 20, or false nails, a layer of the coating R.

container <B> 11 </ B> comprises a wiper member 14 for squeezing the application element <B> 13 to </ B> its output.

matrix 20 comprises on one face 21 a diffraction grating in the form of micro reliefs.

diffraction grating makes it possible to produce an optically variable image such as a hologram.

such matrices can be manufactured for example by the companies SPECTRATEK 5405 Jandy Place, 5406 Los Angeles, California <B> 90066, USA </ B> or HOLOGRAM <B> INDUSTRIES, </ b> 22 avenue de l'Europe, <B > 77600 </ B> Bussy Saint-Georges, France. Preferably, a matrix having micro-reliefs the size of which is large enough to easily leave an impression on the coating deposited on the skin is used. The micro reliefs can thus be relatively coarse.

The micro reliefs are here arranged to produce goniochromatic effects and / or relief or volume effects and / or the appearance and disappearance of elements in the observation direction of the matrix. The die 20 may comprise a sheet of metal or plastic, embossed, engraved or molded.

The matrix 20 serves as a master structure for producing, in contact with a coating layer deposited on the skin, a roughness which will create an optically variable image. The coating R can be constituted by a varnish <B> to </ B> nails, a red <B> to </ B> lips a mascara more generally any dermatologically acceptable composition and / or cosmetic and able to take substantially , at least partially, the footprint of the micro-reliefs of the matrix.

To use the makeup device <B> 1, </ B> in a first example of implementation of the invention, it is first applied by means of the packaging and application device <B> 10 </ B> a layer of coating R <B> to </ B> the liquid state on the <B> region to </ B> make up, for example on the skin P of the face as illustrated in Figure 2.

Then, immediately or after a suitable drying time, the face 21 having the micro-reliefs of the matrix 20 is applied to the coating layer R, as illustrated in FIG. 3. The matrix 20 is applied. on the coating layer R before it has dried, so that the still liquid coating comes into contact with the micro-reliefs of matrix 21. The matrix 20 is then left immobile on the skin for the time sufficient for the coating layer R dry on the surface. If necessary, the immobilization of the matrix is carried out on the support, here skin, during the drying time <B> to </ B> by means of adhesive fixing means, for example by means of an adhesive tape.

When the matrix 20 is removed, as illustrated in FIG. 4, the surface of the coating R is observed <B> at <B> 31 </ B> having micro-reliefs providing an optically variable image.

In another implementation of the invention, it is allowed to dry without applying the matrix 20 the layer <B> 30 </ B> coating R for a time sufficient for it to be dry touch but still sufficiently deformable to receive the imprint of the matrix. By pressing the face 21 of the matrix 20 on the layer <B> 30 </ B> of coating R, micro-reliefs <B> are created at </ B> its surface. To exert sufficient pressure on the coating layer, a device 40 can be used as shown in FIG. 5, this device comprising a support piece 41 on the the bottom face of which is fixed, by its face 22 opposite <B> to </ B> the face the matrix 20.

This support piece 41 is movable <B> to </ B> inside a gripping member 42 against the return action of a spring 43 working in compression.

The piece 41 has a shoulder 44 <B> to </ B> its upper part, this shoulder resting against rest against an inner rim 45 of the gripping member 42.

The distance between the upper face 46 of the support member 41 and the bottom 47 of the gripping member 42 is greater <B> than </ B> the distance between the plane of the face 21 of the die and the edge lower 48 of the gripping member 42, so that when the device 40 is pressed against the skin, the lower edge 48 bears on the latter and the spring 43 is shortened by a predetermined stroke which allows to apply the matrix 20 with a force adapted to the skin.

This force is chosen so <B> to </ B> allow to create micro-reliefs <B> to </ B> the surface of the layer <B> 30 </ B> of coating without exerting too much pressure large which would damage it, especially if the heart of it has not dried enough. The die 20 may also be attached, as shown in FIG. 6, to a support device <B> 50 </ B> having a roll <B> 51 </ B> on the outer surface of the die. which is referred to the die, this roll <B> 51 </ B> turning <B> to </ B> inside a fork secured to a handle <B> 53. </ B> In a variant not shown, the die is made directly <B> at </ B> the surface of the roll.

In the implementation variants of the invention have just been described, the optically variable image is formed <I> in situ </ I> on the coating previously <B> deposited </ B> a keratin support or false nails or false eyelashes.

In another implementation of the invention, the optically variable image is formed on the coating before it is applied to a keratinous support or false nails or false eyelashes.

FIG. 7 shows a matrix 20 coated on its face 21 having the micro-reliefs of a first coating layer 60.

After its application on the matrix, sufficient coating is allowed to dry so that its face <B> 62 </ B> in contact with the face 21 of the matrix takes the impression of the micro-reliefs of the latter.

After drying the first layer <B> 60, the user applies a second coating layer on the first layer, this second layer being intended to ensure the adhesion of the first layer <B> 60 </ B> on the support <B> to </ B> make up.

Before this second layer <B> 61 </ B> is dry, the user applies the set on the support <B> to make up, for example a fingernail as illustrated on figure <B> 9. After drying of the second coat layer, the matrix 20 is peeled off from the first coat layer as shown in FIG. 10. . </ B>

The face <B> 62 </ B> becomes apparent, producing an optically variable image. A coating having the following formulation may be used: <B> <B> - <B> - </ B> ethyl alcohol <B> .................... ................................................ 2, 9% <B> - </ B> water <B> ................................ .............................. .................... </ B> qs 100.0% <B> - </ B> plasticizer <B> ......... .................................................. ................... 2,6% <B> - </ B> thickener <B> ........... .................................................. .............. 1.3% <B> - </ B> conservative <B> ................ .......................................... ......... ....... </ B> sufficient quantity <B> - </ B> pigments <B> ......................... .................................................. </ B> 1.5% <B> - </ B> aqueous polyurethane dispersion <B> 30% </ B> active ingredient <B> 75.6% </ B> also use a coating without pigment, having the same formulation as above, except the presence of the pigment.

For a peelable nail with the above formulation, a few minutes after the first layer is applied to the matrix before applying the second layer, then immediately apply all on the nail. We wait a few more minutes and we remove the matrix.

We will now describe, with reference to Figures <B> Il <I> to </ I> 15, </ B> the realization in <I> situ </ I> of a holographic makeup on a nail <B> N . </ B>

An adhesive support <B> 70 </ B> consisting of an adhesive tape, coated on its adhesive side with a layer <B> 71 </ B> of foam, on which a matrix <B> 72 is fixed is used. </ B>

The <B> 71 </ B> layer covers only the center portion of the <B> 70 tape. </ B>

The matrix <B> 72 </ B> has a face <B> 73 </ B> adhered to the foam layer and an opposite face 74 having micro-reliefs capable of producing an optically variable image.

The foam layer has a thickness of between 2 and <B> 8 </ B> mm, for example. To make a hologram on the nail <B> N, </ B> one starts, as illustrated in the figure <B> 13, </ B> by depositing a layer of a peelable varnish having for example the composition given more high, as uniform as possible.

Then allow to dry a few minutes (between <B> 3 </ B> and <B> 5 </ B> minutes) and then fix one end of the tape <B> 70 </ B> on the finger of the opposite side <B > to </ B> the nail <B> N </ B> and we wrap the ribbon around the finger so <B> to </ B> bring without sliding the matrix <B> 72 </ B> in contact with the varnish previously deposited on the nail <B> N, </ B> as illustrated in FIG.

This way of proceeding has the advantage of reducing the risks of moving the matrix relative to the varnish deposited on the nail.

After ten minutes, the varnish is dry and the matrix is removed by starting off one end of the adhesive tape <B> 70, </ B> as shown in Figure <B> <I> 15. </ I In all the examples of implementation of the invention above, the matrix can be made from the image of a real object or by synthesis by means of a computer calculating the thickness of each point of the matrix in order to obtain the desired optical effect. The user can then easily choose the image that will be produced by the matrix on the coating, for example the pattern of his choice. The matrix may be coated, before use, with a removable protective film. The coating having received the impression of the matrix may be covered by a protective layer intended to protect it, for example a transparent varnish. The coating may or may not include pigments, the invention making it possible to obtain an optical effect even in the absence of pigment.

The coating may be formulated to have a metallic appearance.
