[Effect of invention]

According to the present invention, it is possible to provide a photorealistic skin film that can improve the abnormality of air volume retention during and after attachment, and can present a natural makeup.

Hereinafter, an embodiment of the present invention will be described in detail. The present invention is not limited to the following embodiments, and can be implemented with various modifications within the scope of the gist of the invention.

The simulated skin film of the present invention has a rubber hardness of 20 or less and a film thickness of 600 μm or less according to JIS K6253, and the through holes are arranged at a rate of 3 to 500,000 pieces/cm ² . The area is 70～283000 μm ² /piece.

According to the realistic skin film of the present invention, the abnormality of air volume retention during and after attachment can be improved, and natural makeup can be presented.

It is believed that the photorealistic skin film of the present invention can improve the abnormality of air volume retention during and after attachment, and can show natural makeup. The principle of action is as follows, but it is not limited by this principle.

It is believed that the realistic skin film of the present invention has a specific hardness, so it is easy to follow the wrinkles and other irregularities in the skin or the movement of the skin, and because it has a specific thickness, it can provide a fullness naturally and without abnormal feeling. The appearance.

It is believed that since the simulated skin film of the present invention has through-holes of a specific size formed at a specific ratio, it can exhibit breathability without adversely affecting the natural appearance of the appearance, and as a result, can be accompanied by less adhesion The gas (bubble) generated when the skin is breathed, etc. during or after sticking, can maintain a natural makeup. In addition, it is believed that the improvement in the retention of gas volume is also related to the increase in the contact area between the membrane and the skin, so the adhesion of the membrane to the skin can also be improved.

In addition, it is considered that the realistic skin film of the present invention having a through hole of a specific size has excellent balance between air permeability and storage effect (effect of preventing water loss from the skin), so when the film is applied to the skin, it may be Improve the dryness or roughness of the skin.

The specific through holes formed in the photorealistic skin film improve the adhesion of the photorealistic skin film. The reason for this is considered to be that, for example, the adhesive applied to the lips penetrates into the through-hole and easily adheres to the film. Also, for example, when the film is formed of a material such as silicone rubber, the adhesion to the film also increases, so the adhesion of lip gloss, lipstick, nail polish, liquid foundation and other applicators is also improved.

Furthermore, it is considered that the phantom skin film of the present invention has a specific through hole, so that it can increase flexibility and reduce hardness compared to a film without the through hole. As a result, it is easy to expand and contract even the parts with a lot of movement, such as wrinkles and peeling. Furthermore, by forming specific through holes, even materials that are harder and previously unsuitable for a realistic skin film can also be used as the material of the film.

"Realistic Skin Mask" <rubber hardness> The rubber hardness measured by the A-type hardness tester according to JIS K6253 in the simulated skin film of the present invention is 20 or less. The hardness is preferably 15 or less or 10 or less from the viewpoint of followability to the skin, and preferably 1 or more, 2 or more or 3 or more from the viewpoint of strength and the like. Here, the rubber hardness may refer to the rubber hardness of a test piece having a thickness of 6.0 mm or more prepared by using a material constituting a phantom skin film or a test piece having a thickness of 6.0 mm or more prepared by a laminated phantom film.

<film thickness> The thickness of the simulated skin film of the present invention is 600 μm or less. The film thickness of the film can be appropriately adjusted according to the location to which the film is attached or the purpose of use, for example, it can be set to 500 μm or less, 400 μm or less, 300 μm or less, or 200 μm or less, or 50 μm or more. 70 μm or more, or 100 μm or more, but not limited to these.

In particular, in the case of using a film to make the lips look plump for parts that frequently move like lips, the film thickness can be set to 300 μm or less, or 200 μm or less, and can also be set to 50 μm or more, 70 μm Above, or above 100 μm.

Here, the film thickness is an average value calculated using a precision thickness measuring machine (PEACOCK dial gauge thickness 0.01 mm model manufactured by Ozaki Manufacturing Co., Ltd.) to measure the film thickness of any part of the realistic skin film five times, and In the case where the realistic skin film is provided with a peeling sheet, it means the film thickness in a state other than the thickness of the peeling sheet.

The simulated skin film of the present invention can vary the film thickness within the film surface according to its application site or use purpose. For example, when the film is applied to the lips, the central portion of the film can be thickened and the peripheral portion thinned. With this configuration, it is not easy to make the boundary between the skin and the membrane obvious, and it can further enhance the fullness of the lips. In addition, in this case, the said film thickness is the average value measured in the thickest part (thickest part) of a realistic skin film similarly to the above.

In order to easily follow the movement of wrinkles or skin according to the application site, for example, a slit-like incision line can be cut on the surface of the skin to be attached to the skin such as the lips or the eyes.

<Through Hole> The realistic skin film of the present invention is provided with a through hole at a rate of 3 to 500,000/cm ² , and the through hole has an area of 70 to 283000 μm ² /piece.

As long as the through-holes are formed at the above-mentioned ratio, they can be distributed uniformly or unevenly over the entire surface of the phantom skin film, or they can be evenly or unevenly distributed over a part of the phantom skin film. Here, when a through hole is formed in a part of the phantom skin film, it is sufficient to satisfy the above ratio at one or more, two or more, or three or more.

(Area of through-hole) The area of the through-hole can be set to 70 μm ² /piece or more, 80 μm ² /piece, 100 μm ² / from the viewpoint of improvement of air volume retention, permeability, flexibility, etc. one, or ^more 150 μm / month, and can be set to 283000 μm ² / less, 233000 μm ² / less, 183000 μm ² / less, or 133000 μm ² / less. Here, the area of the through-hole means the smallest area among the areas of the through-holes in the upper surface and the bottom surface of the simulated skin membrane. For example, when the through hole is in the shape of a truncated cone that cuts the upper part of the cone parallel to the bottom surface, it refers to the area of the upper surface of the truncated cone, and is the cylinder with the same area of the upper surface and the bottom surface In the case of a shape, it refers to the area of either the top or bottom surface.

(Shape of through hole) The shape of the through-hole is not particularly limited as long as it can improve the performance of gas volume retention and the like, and examples thereof include a substantially cylindrical shape, a substantially elliptic cylindrical shape, a substantially angular columnar shape with a polygonal bottom surface, a substantially truncated cone shape, It has a substantially truncated cone shape with an elliptical truncated cone and a polygonal bottom. Among them, from the viewpoints of productivity and improvement of gas volume retention, it is preferably a substantially cylindrical shape and a substantially truncated cone shape. Here, "approximately" means including deviations due to manufacturing errors, etc., and means that variations of about ±20% are allowed.

In the case where the shape of the through hole is substantially cylindrical and substantially truncated conical, the smallest diameter of the substantially circular portion of the through hole in the upper and bottom surfaces of the membrane from the viewpoint of improvement of gas volume retention, etc. It is preferably 0.01 mm or more, 0.02 mm or more, or 0.03 mm or more, and preferably 0.60 mm or less, 0.50 mm or less, or 0.40 mm or less.

<Material> The material of the phantom skin film of the present invention may be any material as long as it has a rubber hardness of 20 or less, and is not limited to the following. For example, olefin rubber, urethane rubber, silicon Synthetic rubbers such as ketone rubber and acrylic rubber, gels that can exhibit elasticity like α-gel, natural rubber, etc. Among them, from the viewpoints of skin safety, durability, transparency, etc., silicone rubber is preferred. These materials can be used alone or in combination. Furthermore, the realistic skin film may be a single layer or a laminated structure of these materials.

As a preferable material of the silicone rubber, for example, from the viewpoint that it can be molded in a short time by heating, it is preferable to add an addition (silicon hydrogenation) reaction hardening type silicone rubber composition or organic peroxide The hardened silicone rubber composition is obtained by curing, but it is not limited thereto.

As the addition reaction hardening type silicone rubber composition, a known composition can be used, for example, an alkenyl group-containing organic polysiloxane containing one or more alkenyl groups represented by vinyl groups in one molecule, Organic hydrogenated polysiloxane having 2 or more, preferably 3 or more SiH groups (usually, the molar ratio of SiH groups to alkenyl groups is 0.5 to 4), and platinum group represented by platinum or platinum compounds Metal-based addition reaction catalyst (usually 1 to 1000 ppm relative to alkenyl group-containing organic polysiloxane).
