For the purposes of the present invention, the term “polymer” means a compound corresponding to the repetition of one or more units (these units being derived from compounds known as monomers). This or these units(s) are repeated at least twice and preferably at least three times.
[0092] The oil-soluble film forming agent can be hydrophobic, and thus can improve or enhance the durability of the anhydrous composition against water. For the present invention, the oil-soluble film forming agent is preferably selected from silicone resins.
[0093] - Silicone Resin
[0094] As the silicone resin, mention can be made of silsesquioxane, siloxysilicate and a resin obtained by hydroxysilylation. In particular, the silicone resin is selected from silsesquioxane, siloxysilicate, and mixtures thereof.
[0095] The nomenclature of the silicone resin is known in the art under the name of “MDTQ” nomenclature, by which a silicone resin is described according to the various repeating siloxane monomer moieties which constitute the polymer. Each letter of “MDTQ” corresponds to a different type of moiety.
[0096] The symbol “M” corresponds to the monofunctional moiety Rh-SiOi / z. This moiety is regarded as monofunctional because the silicon atom shares only one oxygen for the formation of the chain. The R1group indicates a hydrocarbon group, preferably an alkyl group or aryl group, and more preferably Ci-Cio alkyl group, in particular C1-C4 alkyl group, such as a methyl group, an ethyl group, a propyl group, or a butyl group. The “M” moiety can be represented by the following structure.

The R1group indicates the same as explained above. The “T” moiety can be represented by the following structure.
[0100] As in the “M” moiety, any one of the methyl groups can be replaced in “D” or “T” by an R group which is other than methyl.
[0101] Finally, the symbol “Q” corresponds to a quadrifunctional moiety SiC>4 / 2, in which all four available bonds on the silicon atom are used to bond with oxygen for the formation of the polymer chain. The “Q” moiety can be represented by the following structure.
[0102] As described above, in one embodiment of the present invention, the silicone resin may be selected from the siloxysilicate, silsesquioxane and a resin obtained by hydroxysililation.

Preferably, the silicone resin is crosslinked.
[0103] According to one embodiment of the present invention, the silicone resin may be selected from substituted siloxysilicate, silsesquioxane and resin obtained by hydroxysilylation. A substituted siloxysilicate or a substituted silsesquioxane may be, for example, a siloxysilicate or a silsesquioxane in which a methyl group has been replaced by a longer carbon chain, such as an ethane, propane or butane chain. The carbon chain may be saturated or nonsaturated.

[0106] According to another embodiment of the present invention, a siloxysilicate may be selected from all the combinations of M and of Q moieties such as, for example, [(R)3Si]x(SiOa / 2)y, in which R is selected from a methyl group and a longer carbon chain.
[0107] In one preferred embodiment, the siloxysilicate is trimethylsiloxysilicate, which is represented by [(CH3)3SiO]x(SiO4 / 2)y in which x and y represent from 10 to 150, preferably from 20 to 120, more preferably from 40 to 100, and in particular from 50 to 80, for example, sold by the company Momentive Performance Materials under the name SR 1000 MQ Resin.
[0108] According to another embodiment of the present invention, the silicone resin may be selected from silsesquioxane, which may substantially consist of T moieties. The silsesquioxane can be represented by the following formula:
[0109] (R*SiO3 / 2)x (T moieties), in which x has a value which can range up to several thousands and R1indicates a hydrocarbon group, preferably an alkyl group or an aryl group, and more preferably Ci-Cio alkyl group, in particular Ci-C4alkyl group, such as a methyl group.
[0110] Mention may be made, among the silsesquioxane, of the alkyl silsesquioxane resins which are silsesquioxane homopolymers and / or copolymers having an average siloxane unit of formula R2nSiO(4-n) / 2, where each R2independently denotes a hydrogen atom or a C1-C10 alkyl group, where more than 80 mol% of the R1radicals represent a C3-C10 alkyl group, and n is a number from 1.0 to 1.4, and more particularly use will be made of a silsesquioxane copolymer in which more than 60 mol% comprises R2SiO3 / 2 units in which R2has the definition indicated above.
[0111] Preferably, the silsesquioxane resin is chosen so that R2is a C1-C10 alkyl group, preferably a C2-C4 alkyl group and more particularly a propyl group. Use will more particularly be made of a poly(propyl silsesquioxane) or t-propyl silsesquioxane resin (INCI name: Polypropylsilsesquioxane (and) Isododecane), such as the product sold under the trade name Dow Corning® 670 Fluid by Dow Coming.

[0243] EXAMPLES
[0244] The present invention will be described in a more detailed manner by way of examples.
[0245] However, these examples should not be construed as limiting the scope of the present invention. The examples below are presented as non-limiting illustrations in the field of the present invention.
[0246] (Manufacturing Procedure)
[0247] A primer composition used in the examples was prepared by mixing the ingredients listed in Table 1 below until it became homogeneous. The numerical values for the amounts of the ingredients are all based on “% by weight” as active raw materials.
[0248] Table 1
[0249] An ink composition used in the examples was prepared by mixing the ingredients listed in Table 2 below until it became homogeneous. The numerical values for the amounts of the ingredients are all based on “% by weight” as active raw materials. Table 2
[0250] Anhydrous compositions 1 and 2 were prepared by mixing the ingredients shown in Table 3 until they became homogeneous. The numerical values for the amounts of the ingredients are all based on “% by weight” as active raw materials.
[0251] Example 1
[0252] The primer composition was filled in a plunged applicator. The ink composition was placed in a cartridge of a skin transfer printer (Prinker M, Prinker). Anhydrous composition 1 was filled in a plunged applicator. The primer composition was applied to a face with a flocky tip, then dried at 25°C for 1 minute, to prepare a primer layer on the facial skin. The design was then printed on the primer layer with the ink composition by using a skin transfer printer (Prinker M, Prinker), then the design was dried at 25°C for 1 minute. Finally, the coating composition was applied to the printed design, dried 1 minute to form a coating layer on the design. All steps were done at 25°C.
[0253] Comparative Example 1 Example 1 was repeated, but the anhydrous composition 2 was used instead of the anhydrous composition 1.
[0254] Comparative Example 2
[0255] Example 1 was repeated, but no anhydrous composition was used. Thus, in this comparative example, no coating layer was prepared.
[0256] [Evaluations]
[0257] (Water resistance)
[0258] Water resistance was evaluated for each of Examples 1 and 2 and Comparative Example 1. Specifically, 5 minutes after the final printing, 10 ml of water was applied to each of the samples at a rate of 1 ml / s. After rubbing 5 times with a tester (Rub. Tester, Sketch-On), the ratio of the remaining area to the area before rubbing was measured. The evaluation was made under the following criteria.
[0259] Good: More than 90% of the area was remained.
[0260] Fair: 70 to 90% of the area was remained.
[0261] Bad: Less than 70% of the area was remained.
[0262] The results are shown in Table 4.
[0263] Table 4
[0264] As shown in Table 4, the process according to the present invention using the anhydrous composition of the present invention could improve water resistance of the ink deposition.
[0265] On the other hand, the process according to Comparative Example 1 , which did not use an anhydrous composition of the present invention, could not exhibit improved water resistance. In addition, the process according to Comparative Example 2, which lacked the step of applying anhydrous composition of the present invention, could not exhibit improved water resistance.
[0266] Accordingly, it can be it can be concluded that the process according to present invention can make up design printed with an ink composition on keratin material, such as temporary tattoo, with an improved water resistance.
