Description

DESCRIPTION OF THE FIGURES

(1) The invention may be understood more clearly on reading the following description and on examining the attached drawing, in which:

(2) FIG. 1 shows an example of a makeup device used in a process according to the invention,

(3) FIG. 2 is a section along II-II of the makeup device of FIG. 1,

(4) FIGS. 3 to 6 represent different steps of an example of a makeup process according to the invention,

(5) FIG. 7 shows an example of a transfer makeup result produced according to the invention, and

(6) FIG. 8 shows a kit according to the invention.

(7) FIGS. 1 and 2 show a makeup device 1 comprising a substrate 2 whose front side defines a transfer surface 3. The device 1 may, as illustrated, have only one face defining the transfer surface 3, bearing a coat 4 of at least one cosmetic colouring ink according to the invention.

(8) In one variant, not shown, two transfer surfaces 3 are defined by the two opposite faces of the substrate 2. In this case, these surfaces may bear coats of different cosmetic colouring inks, these coats possibly differing by their colour, the nature of the colouring inks borne and/or by the patterns formed.

(9) In the device 1 illustrated in FIGS. 1 and 2, the coat of colouring ink 4 borne by the transfer surface 3 was deposited by printing using a digital printer, which deposits the ink dots in correspondence with the pixels of an image to be reproduced, for example in the form of rasters.

(10) The coat of colouring ink 4 may form any type of pattern, for example in the form of two butterflies as illustrated.

(11) Preferably, the substrate 2 has at least one non-opaque area 5, which is preferably transparent or translucent, and which may totally or partly be superposed with the coat of colouring ink 4. The transparent area 5 allows the user to see through the substrate 2 and thus to visualize the surface to be made up through the device 1 when this device is superposed on the said surface.

(12) All of the coat of ink 4 may, as illustrated, be superposed on the transparent area 5. In one variant, not shown, only part of the coat of ink is superposed on the transparent area 5.

(13) The substrate 2 may be made of a transparent material. The transparent area 5 then extends over the entire surface of the substrate 2.

(14) The substrate 2 may bear an indication 7, for example a print, which gives information regarding a recommended positioning for the makeup, or the nature of the keratin materials intended to be made up with the colouring ink 4, or the like, and may also provide information regarding the colour and/or pattern reference. Indication 7 illustrates, for example at a reduced scale, “fight side” on the deposited pattern and “wrong side” on the substrate 2.

(15) The pattern may be monochromatic or, better still, polychromatic. In this case, the coat of ink 4 may comprise several cosmetic inks that are locally juxtaposed at the microscopic scale, depending on the colour to be reproduced. The resolution of the printed pattern defined by the coat 4 may be between 16 dpi and 1600 dpi.

(16) The coat of ink 4 may comprise several successive deposits of ink at the same place, so as to increase the amount of ink deposited on the substrate. The density of cosmetic ink dry matter of the coat 4 ranges, for example, from 0.01 mg/cm.sup.2 to 100 mg/cm.sup.2, or even from 0.1 mg/cm.sup.2 to 10 mg/cm.sup.2, better still from 0.2 mg/cm.sup.2 to 10 mg/cm.sup.2, in particular from 0.2 mg/cm.sup.2 to 5 mg/cm.sup.2.

(17) The substrate 2 is preferably made of a flexible material. As a variant, the substrate 2 is made of a rigid or semi-rigid material.

(18) All or part of the area of the transfer surface 3 superposed on the coat 4 is preferably smooth and has a roughness of less than or equal to 1 mm, especially between 1 μm and 100 μm and preferably less than or equal to 50 μm. The roughness is measured using a roughness meter, the tip of which has a radius of curvature of 10 mm, and the force of which, applied to the material to be characterized, is 6 mN.

(19) FIGS. 3 to 6 schematically show various steps of an example of a makeup process according to the invention for making up an area of keratin materials P, in this case the lips.

(20) As shown in FIG. 3, prior to transferring the ink of the coat 4, the area P is covered with a base coating 6 to prepare the area P and to facilitate the transfer of the cosmetic ink. In this example, the coating 6 is colourless.

(21) Next, as illustrated in FIG. 4, the device 1 is brought close to the area P to be made up, so as to place the coat of colouring ink 4 in contact with the area P to be made up, and the user then applies a pressure allowing the ink 4 to be transferred onto the area P to be made up. During the contact with the keratin materials, the substrate 2 is preferably not moved sideways so as not to affect the appearance of the transferred pattern.

(22) The pattern transferred onto the keratin materials corresponds to the pattern formed by the coat of colouring ink 4 when it is present on the substrate 2 (i.e. when it has not yet been transferred onto the keratin materials to be made up).

(23) In one example, not shown, the process also comprises a step of finishing the makeup result obtained on the keratin materials.

(24) FIG. 8 shows an embodiment example of a kit 30 for performing the process according to the invention. This kit comprises, in the same case, a plurality of devices 1 as described previously, each differing by the nature or form of the substrate 2 and/or by the pattern formed by the coat 4, especially its shape and/or its colour. The assembly also comprises a packaging assembly 50 containing a composition C comprising an oil, this composition being capable of forming a base coating 6 on the area P of the keratin materials to be made up.

(25) The case may be leaktight so as to prevent the inks from drying out. The case may be made with means for preventing contact of the inks with a surface other than the transfer surface, so as to reduce the risk of premature transfer. For example, the case comprises a thermoformed shell whose wall extends at a distance from the areas of the substrate that are covered with inks.

EXAMPLES

(26) Four inks corresponding to the formulations given in the table below were prepared:

(27) TABLE-US-00001 Yellow I Magenta I Cyan I Black I Dye 1% 1% 1% 1% Isopropanol 8% 8% 8% 8% Ethanol 10%  10%  10%  10%  Water qs 100% qs 100% qs 100% qs 100%

(28) These compositions are placed in Canon printer cartridges, and then used with a Canon Pixma IP100 inkjet printer, which is requested to print a makeup pattern produced with the PowerPoint® software, for example. The printing is performed on a transparent plastic sheet for a commercial printer (smooth side).

Example 1

In the Case of the Skin

(29) This example corresponds to FIG. 7.

(30) A single-colour pattern is produced by printing a coat of cosmetic ink 4 onto a substrate 2 in the form of a transparent plastic printer sheet using a digital printer.

(31) This sheet is left for four days before use.

(32) A coating 6 is produced on an area P of skin of an arm, with a foundation whose composition is described below.

(33) TABLE-US-00002 Foundation composition Ingredients (weight %) Magnesium sulfate 1.50 Distearyldimethylammonium- 1 modified hectorite (Bentone 38 VCG from Elementis) Titanium dioxide 21.20 Iron oxides 3.8 Sodium carboxymethylcellulose 0.50 (Blanose ® 7M8SF from Ashland) Cyclopentasiloxane 15.30 Polyglyceryl-4 isostearate cetyl 9 PEG/PPG-10/1 hexyl laurate (Abil WE 09 from Evonik Goldschmidt) Polydimethylsiloxane (viscosity: 5 cSt) 6.60 (Xiameter PMX-200 Silicone Fluid 5 cs from Dow Corning) Glycerol 5 Pentylene glycol 3 Water qs 100

(34) The plastic sheet covered with the coat of ink is then placed on the arm, and the plastic sheet is then removed.

(35) Transfer of the pattern with partial integration onto the applied foundation is noted.

(36) It is observed on the plastic sheet that the step of transferring the ink has not removed the foundation from the skin.

(37) The same experiment is performed on the other arm, without prior application of foundation. No transfer is obtained.

Example 2

In the Case of the Lips

(38) This example corresponds to FIGS. 1 to 6.

(39) A makeup device 1 is produced by printing a coat 4 of cosmetic ink forming two butterfly-shaped multi-coloured patterns onto a transfer surface 3 of a plastic sheet.
