Description

DESCRIPTION OF THE FIGURES

(1) The invention may be understood more clearly on reading the following description of non-limiting implementation examples thereof, and on examining the attached drawing, in which:

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

(6) FIG. 8 shows an example of a transfer makeup application obtained via a process according to the invention, and

(7) FIGS. 9a and 9b illustrate examples of transfer makeup applications, with and without the coating according to the invention.

(8) FIGS. 1 and 2 show a makeup device 1 according to the invention, 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.

(9) 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.

(10) 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 spots in correspondence with the pixels of an image to be reproduced, for example in the form of raster frames. This coat 4 is not entirely dry at the time of application to the keratin materials.

(11) The coat 4 may form any type of pattern, for example in the form of a heart as illustrated.

(12) The substrate 2 may have at least one non-opaque area 5, which is transparent or translucent, and which may totally or partly be superposed with the coat 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.

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

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

(15) The substrate 2 may bear an indication 7, for example print, which gives information regarding a recommended positioning for the makeup, for example “right cheek” as illustrated, or a reproduction of the place and scale, reduced or not, of the pattern to be transferred or the nature of the keratin materials intended to be made up with the colouring ink, or the like, and may also provide information regarding the colour reference and/or the pattern.

(16) 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.

(17) 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 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.

(18) FIGS. 3 to 6 schematically show various steps of an example of a makeup process according to the invention. As illustrated, the device 1 is first brought close to the area of skin P to be made up, which is preferably dry, so as to place the coat 4 in contact with the area of skin P to be made up, and the user then applies a pressure allowing the colouring ink to be transferred onto the area of skin 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.

(19) The pattern transferred onto the keratin materials corresponds to the pattern formed by the coat 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).

(20) Next, as illustrated in FIG. 6, a coating 8 is formed, for example by spraying a composition C according to the invention as described above onto the coat of ink 4.

(21) The coat of ink 4 is, for example, dry at the time of spraying. In one variant, the coating is formed on a coat of ink that is not entirely dry.

(22) The composition C is sprayed, for example, using a pressurized packaging assembly 50 of aerosol type, actuated by the user.

(23) FIG. 7 shows an embodiment example of a cosmetic assembly 30 according to the invention. This assembly 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 film-forming composition C intended to form a protective coating 8 on the coat of ink, once transferred onto the keratin materials. In the example illustrated, the composition C is contained in a container of aerosol type. In another variant, the composition is not sprayed, but is applied, for example, with a pad of cotton wool or a fine brush.

(24) The case may be leaktight so as to prevent the inks from drying out. The case may be made with means for avoiding 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 a distance from the areas of the substrate that are covered with inks.

EXAMPLES

Example 1

In the Case of the Skin

(25) This example corresponds to FIG. 8.

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

(27) TABLE-US-00001 TABLE 1 Yellow I Magenta I Cyan I Black I Dye D&C FD&C Red 4 FD&C Blue 1 (1) Yellow 8 1% 1% 1% 1% Ethylene glycol 4% 6% 5% Diethylene glycol 8% 1,5-Pentanediol 4% 4% 2-Pyrrolidone 5% 5% 4% Glycerol 8% 3% 4% 7% 2-Imidazolidinone 4% 4% 4% 9% Water 76%  79%  77%  78%  Total 100%  100%  100%  100%  (1) Brown-Replacement-J from Sensient

(28) These compositions are introduced into Canon printer cartridges and then used with a Canon Pixma IP100 inkjet printer.

(29) Two identical patterns of cosmetic ink are printed on a plastic sheet.

(30) This plastic sheet is placed on the surface of the skin. Simple pressure on the sheet suffices to transfer the ink, thus resulting, by transfer, in the appearance of two patterns. The sheet is removed.

(31) A composition is then prepared according to Formula 1 below:

(32) TABLE-US-00002 Formula 1 Sulfopolyester sold under the name 15% (solids) Eastman AQ 38 by the company Eastman Chemical Water qs 100%

(33) A pad of cotton wool is soaked with the composition and placed on one of the two patterns.

(34) Next, the two patterns are stressed by washing with soap.

(35) It is seen that the pattern covered with Formula 1 withstands this stress much better.

Example 2

(36) The process is performed as in Example 1, and two identical patterns are produced on the skin.

(37) The following formula is then prepared, and placed in a lacquer-type aerosol container.

(38) Formula 2 is sprayed onto the surface above one of the two patterns, at a rate of 2 g per 100 cm.sup.2.

(39) TABLE-US-00003 Formula 2 Acrylic acid/ethyl acrylate/N-tert-butylacrylamide terpolymer  5 g sold under the name Ultrahold Strong by the company BASF Ethanol 60 g DME 35 g

(40) Next, the two patterns are stressed with a succession of three 20-minute baths, with drying between each bath.

(41) It is seen that the pattern covered with Formula 2 withstands this stress much better: whereas the pattern without the coating has virtually disappeared, the pattern formed by the coat of ink 4 covered with the protective coating 8 has kept its precision.

Example 3

(42) An HP LaserJet Pro 400 M451 NW printer, modified to delete the heating member, is used.

(43) The electronic system is modified to prevent an operating error following the removal of the heating roller. The thermistor used for measuring the temperature is especially replaced with a resistance simulating a temperature normally encountered of the heating roller.

(44) Removal of the heating roller makes it possible to minimize the mechanical stresses during printing without melting the toners.

(45) The following preparation is used as cosmetic toners: A toner of an HP Laser jet pro Color M451nw printer is taken. After opening, the existing powder is removed and replaced with a powder (40 g) containing 6 g of ferrite, 33 g of carbon black powder and 1 g of calcium carbonate, rendered pulverulent by blending with aeration.

(46) Printing is performed on a sheet of transparent type for a Laser printer.

(47) The printed pattern is applied by transfer onto the skin just after printing. The sheet is placed on the skin with a pressure of 50 g/cm.sup.2 for 5 seconds. The sheet is then removed.

(48) To complete the makeup, a composition intended to form a protective coating, containing a resin, is sprayed on, at a distance of 30 cm. To do this, an Elnett® brand hair lacquer is used. It is left at rest for 1 minute. The makeup application is then complete.

(49) The expression “comprising a” should be understood as being synonymous with “comprising at least one”.

(50) The expression “between . . . and . . . ” or “ranging from . . . to . . . ” should be understood as including the limits.
