Description

Technical Field

[0001] The present invention relates to a method for providing a printing ink deposit having improved water resistance to a keratinous material. The present invention also relates to a composition for improving the water resistance of an ink deposit printed on a keratinous material.

Background Art

[0002] Traditional tattoos are a method of infiltrating pigments into the dermis layer of the skin. Although the initial treatment cost is high, once treated, they are permanent and thus not easily removed.

[0003] In recent years, after traditional tattoo procedures, henna tattoos (a method of drawing on the body using ink), water transfer stickers (a form of attaching transfer paper to the body using water), and other body paintings using ink in various ways, such as stamping patterns, have been proposed.

[0004] Among temporary body painting methods, a method of printing on the skin with a two-component skin printing ink has been reported in KR101655978 B1 and KR20180057953 A.

[0005] However, there is still a need to improve the water resistance of temporary ink deposits printed on the skin.

[0203] Lipophilic gelling agents can also be selected from hydrophobic fumed silica, which can be obtained by modifying the surface of silica via a chemical reaction that reduces the number of silanol groups, which are sometimes substituted, in particular, with hydrophobic groups. The hydrophobic group can be a trimethylsiloxyl group, which can be obtained by treating fumed silica, in particular, in the presence of hexamethyldisilazane. Silica treated in this way is known as "silylated silica" in the CTFA Dictionary (6th edition, 1995). They are sold, for example, by Degussa under the reference name Aerosil R812 (registered trademark) and by Cabot under the reference name Cab-O-Sil TS-530 (registered trademark). The hydrophobic group may also be a dimethylsilyloxyl group or a polydimethylsiloxane group, which can be obtained, in particular, by treating fumed silica, in particular, in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silica processed in this manner is known as "dimethylsilylated silica" in the CTFA Dictionary (6th edition, 1995). These are sold, for example, by Degussa under the reference names Aerosil R972® and Aerosil R974®, and by Cabot under the reference names Cab-O-Sil TS-610® and Cab-O-Sil TS-720®.

[0204] The lipophilic gelling agent may also be selected from hydrophobic silica aerogels, such as the product sold by Dow Corning under the name VM-2260 (INCI name: silylated silica), whose particles have an average size of approximately 1000 microns and a specific surface area of ​​600-800 m² per unit mass. 2 This range includes aerogels sold by Cabot under the reference names Aerogel TLD 201, Aerogel OGD 201, Aerogel TLD 203, Enova® Aerogel MT 1100, and Enova Aerogel MT 1200, with a range of / g.

[0205] The lipophilic gelling agent may also be selected from lipophilic polymer thickeners, which may be carboxyvinyl polymers such as Carbopol products (carbomers) and Pemulen products (acrylate / C10-C30 alkyl acrylate copolymers) or polymers having the INCI name "poly C10-30 alkyl acrylate," for example, Air Products' Intelimer® product, for example, Intelimer® IPA 13-1 which is polystearyl acrylate, or Intelimer® IPA 13-6 which is a behenyl polymer.

[0206] The lipophilic gelling agent is preferably an organically modified clay, particularly disteardimonium hectorite.

[0207] The amount of lipophilic gelling agent in the anhydrous composition according to the present invention may be 1% by mass or more, preferably 3% by mass or more, and more preferably 5% by mass or more, based on the total mass of the composition.

[0221] The use of the anhydrous composition of the present invention is as described above in the Method and Composition of the Present Invention. [Examples]

[0222] The present invention will be described in more detail by reference to examples. However, these examples should not be construed as limiting the scope of the present invention. The following examples are presented as non-limiting illustrations in the art of the present invention.

[0223] (Manufacturing procedure) The primer compositions used in the examples were prepared by mixing the components listed in Table 1 below until uniform. All numerical values ​​regarding the amount of components are based on the "mass%" of the active raw materials.

[0224] [Table 1]

[0225] The ink compositions used in the examples were prepared by mixing the components listed in Table 2 below until uniform. All numerical values ​​regarding the amount of components are based on the "mass%" of the active ingredients.

[0226] [Table 2]

[0227] Anhydrous compositions 1 and 2 were prepared by mixing the components shown in Table 3 until uniform. All numerical values ​​regarding the amount of components are based on the "mass%" of the active ingredients.

[0228] [Table 3]

[0229] (Example 1) The plunger-type applicator was filled with the primer composition. The ink composition was placed in the cartridge of a skin transfer printer (Prinker M, Prinker). The anhydrous composition 1 was filled into the plunger-type applicator. The primer composition was applied to the face using a flocked tip and then dried at 25°C for 1 minute to prepare a primer layer on the facial skin. Then, by using a skin transfer printer (Prinker M, Prinker), a design was printed on the primer layer with the ink composition and then the design was dried at 25°C for 1 minute. Finally, the coating composition was applied to the printed design and dried for 1 minute to form a coating layer on the design. All steps were carried out at 25°C.

[0230] (Comparative Example 1) Example 1 was repeated, but anhydrous composition 2 was used instead of anhydrous composition 1.

[0231] (Comparative Example 2) Example 1 was repeated, but no anhydrous composition was used. Therefore, in this comparative example, no coating layer was prepared.

[0232] [Evaluation] (Water resistance) The water resistance of each of Example 1 and 2 and Comparative Example 1 was evaluated. Specifically, 5 minutes after the last printing, 10 ml of water was applied to each sample 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 carried out according to the following criteria. Good: More than 90% of the area remained. Fair: 70 - 90% of the area remained. Poor: Less than 70% of the area remained.

[0233] The results are shown in Table 4.

[0234]

Table  4

[0235] As shown in Table 4, the method according to the present invention using the anhydrous composition of the present invention was able to improve the water resistance of the ink deposit.

[0236] On the other hand, the method according to Comparative Example 1, which did not use the anhydrous composition of the present invention, failed to demonstrate improved water resistance. In addition, the method according to Comparative Example 2, which lacked the step of applying the anhydrous composition of the present invention, failed to demonstrate improved water resistance.

[0237] Accordingly, it can be concluded that the method according to the present invention can produce designs printed with an ink composition on a keratinous material, such as temporary tattoos, which have improved water resistance.
