[0012] Note that nail decoration in this embodiment may include gel nails, manicure (nail polish), sculpture, nail tips, lengthening gel, etc. Also, it may include the steps of applying each of these and the steps of peeling and removing them.

[0013] Gel nails are a method of decorating nails. They are often created by applying a liquid synthetic resin to the nail, then attaching parts or drawing illustrations on top of it, and then applying another liquid synthetic resin on top to prevent the decoration from peeling off. Gel nails may contain synthetic resin and a photopolymerization initiator, and harden when exposed to light, such as an LED light emitting visible light with a wavelength of approximately 385-415 nm or a UV light with a shorter wavelength, allowing the decoration to last for 2-4 weeks.

[0014] Here we will describe the general steps for applying gel nails.

[0015] First, a base coat is applied directly to the nail. The base coat protects the nail and enhances its aesthetic appearance by creating a uniform surface. The components of the base coat may include, but are not limited to, a film-forming component (e.g., synthetic resin), a plasticizer, a thickener, a solvent, a base material, a coloring component, and a photopolymerization initiator. After the base coat is applied to the nail, it is dried or cured by exposure to light such as an LED light or UV light.

[0016] Next, the color coat is applied on top of the base coat and cured by drying or by irradiating with light such as an LED light or UV light. The color coat may also contain the same ingredients as the base coat.

[0017] Next, place stones, studs, pearls, bullion, or other elements, or draw an illustration to create a design, then dry or harden it by exposing it to light such as an LED or UV light. Finally, apply a top coat, and dry or harden it by exposing it to light such as an LED or UV light. The coloring agents used to draw the illustrations and the top coat may contain the same ingredients as the base coat. There may be other steps involved, but the above is a general example.

[0018] After a certain period of time has passed since applying gel nails, the nails will grow. This will expose the base of the nail where the gel nail was not applied, resulting in a loss of aesthetic appeal, and so the gel nails must be removed. This typically involves scraping off the top coat with a file, crushing the parts with pliers, or removing the color coat and base coat with a remover containing an organic solvent such as acetone, and then scraping off any remaining color coat or base coat with a file. Removing the gel nails. This process puts strain on and damages the nails and skin, and takes anywhere from several tens of minutes to several hours. Removal method

[0019] Stickers that are applied to nails before applying a base coat are known. These stickers are applied to the entire nail, and then a base coat is applied on top of them to form the base for gel nails. Because the gel nails can be removed by peeling off the stickers, the amount of remover, such as acetone, used can be reduced, reducing the strain on the nails and skin.

[0020] On the other hand, since the above-mentioned stickers are applied to the entire surface of the nail, even when a gel nail is applied on top of them, the edges of the stickers are exposed to the outside. As a result, the edges of the stickers tend to peel off from the tip or base of the nail. Furthermore, when the nails grow, the edges of the stickers are exposed at the base of the nail, so they tend to peel off from that area, damaging the aesthetics.

[0021] Figure 1 shows an example of a sticker in this embodiment. 1 indicates a nail, and sticker 2 is attached away from the edge of the nail. The edge refers to the edge of the nail, such as the tip of the nail, the base of the nail, or the border between the nail and the skin on both sides.

[0022] 2 is a top view of the sticker 2. As an example, the sticker 2 includes a decorative layer 201 for applying decoration and an adhesive layer 202 below that contains an adhesive substance for fixing to the nail. The decoration may include a part or the entire process of gel nails, or may be the application of nail polish or the like, but is not limited to these.

[0023] 3 is a bottom view of the sticker 2. The adhesive layer 202 on the bottom surface of the sticker 2 includes, for example, an adhesive portion 2021 having an adhesive substance and a peeling portion 2022 that makes the sticker 2 easy to peel off.

[0024] Fig. 4 is a cross-sectional view of the sticker 2 taken along line a (dotted line) in Fig. 2. The sticker 2 includes, for example, a decorative layer 201 for providing decoration and an adhesive layer 202 for securing the sticker to the nail. The adhesive layer 202 includes, for example, an adhesive portion 2021 having an adhesive substance and a peeling portion 2022 for making the sticker 2 easier to peel off.

[0025] The adhesive portion 2021 includes an adhesive substance that fixes the adhesive portion 2021 to the nail. The adhesive substance may be a known adhesive substance. The adhesive portion 2021 may be located at least on the outer peripheral edge of the adhesive layer 202.

[0026] The release portion 2022 has a function of making it easier to peel the sticker 2 from the nail. For example, the release portion 2022 may be an empty space. For example, the release portion 2022 may be an adhesive that peels easily when it contains an aqueous solution such as water, such as a water-based adhesive (which may be, but is not limited to, an acrylic, rubber, polyurethane, or bioadhesive). For example, the release portion 2022 may be an adhesive that dissolves in an organic solvent such as a remover (including, but not limited to, an acrylic solvent-removable adhesive, a rubber solvent-removable adhesive, or a hot-melt solvent-removable adhesive). For example, the release portion 2022 may be an adhesive that peels easily when heated. For example, the release portion 2022 may be a material that swells when it contains an aqueous solution (for example, but not limited to, a superabsorbent polymer, a cross-linked polymer, a cellulose-based water-absorbing material, a polyacrylic acid polymer, or a polymer gel).

[0027] As shown in Figure 1, the sticker 2 is applied to the nail, away from the edge. A base coat is then applied to the entire nail and allowed to dry or harden by exposure to light such as an LED light or UV light. A color coat is then applied over the base coat and allowed to dry or harden by exposure to light such as an LED light or UV light. The base coat or color coat prevents the edge of the adhesive layer 202 from being exposed to the outside, preventing it from peeling off. The gel nail can be created by placing parts on the color coat and applying a top coat. Note that the order of the steps shown in this paragraph may be reversed, and some steps may not be performed.

[0028] In this way, by using the sticker 2 of this embodiment, it is possible to reduce the areas where a base coat or color coat, etc. needs to be applied directly to the nail, thereby reducing the burden on the nail, especially when peeling it off.

[0029] Here, we will explain how to peel off gel nails when they are applied using sticker 2 and the nails grow over time. Figure 5 shows the state of a grown nail, depicting only sticker 2 among the elements that make up the gel nail. When peeling off a gel nail because the base of nail 1 is exposed, first, the tip of the grown nail is scraped off using a file or nail drill machine, for example, up to line b (dotted line) in Figure 5, or cut off together with the gel nail, damaging a portion of it. This exposes peeled portion 2022 to the outside.

[0030] If the peeling portion 2022 is a space or contains a substance that expands when exposed to a water-based solution, a pointed rod-shaped tool (such as, but not limited to, a cuticle metal pusher) can be easily inserted into the space. Next, the adhesive portion 2021 adhered to the nail can be peeled off by moving the tool inserted into the peeling portion 2022 back and forth, thereby peeling off the sticker 2. Alternatively, the tool inserted into the peeling portion 2022 can be used to apply force perpendicular to the nail to the adhesive portion 2021 using the principle of leverage, for example. This allows the sticker 2 to be peeled off along with the gel nail. This allows the use of remover such as acetone or organic solvents to be limited to the edge of the nail, reducing stress on the nail and shortening the time required.

[0031] For example, if the peeling portion 2022 is a water-based adhesive, or an adhesive that peels easily when exposed to a water-based solution, soaking it in water reduces the adhesive's adhesive function, making it easier to peel. In this state, a pointed rod-like tool can be inserted to scrape off the remaining adhesive portion 2021, allowing for peeling. Alternatively, the tool can be used to apply force perpendicular to the nail using the lever principle, peeling off the adhesive portion 2021. This allows the sticker 2 to be peeled off along with the gel nail. In this case, too, it is possible to limit the use of organic solvents such as acetone to only the edge of the nail.

[0032] Another example is described below.

[0033] The adhesive layer 202 may be entirely made of a water-based adhesive, an adhesive that becomes easily peeled when it contains an aqueous solution containing water, etc. In this case, the adhesive portion 2021 also serves as the peeling portion 2022.

[0034] 6, the adhesive portion 2021 may be configured so as not to include a portion of the end of the adhesive layer 202. This portion may be a part of the peeling portion 2022. The portion of the end may be located at the tip of the nail, which makes it easier for the peeling portion 2022 to be exposed to the outside when the gel nail is cut off along with the grown nail.

[0035] The seal 2 may be transparent, may be colored, or may have a color coating function.

[0036] The sticker 2 may be colored, have parts applied, have illustrations printed on it, and may have a top coat applied thereon.

[0037] Linked to other things In this embodiment, an example is described in which gel nails are applied on the sticker 2, but manicure (nail polish), sculpture, nail tips, lengthening gel, etc. may also be applied.

[0038] In this embodiment, an example is described in which the sticker 2 is applied directly onto the nail and then a base coat is applied on top of that, but for example, a base coat may be applied directly to the nail, the sticker 2 may be applied on top of that, and then another base coat or the like may be applied on top of that.

[0039] In this embodiment, the example is described in which the sticker 2 is applied directly to the nail and then a base coat is applied thereon, but it may also be used in other locations and for other purposes. For example, the sticker 2 may be applied on top of a color coat and then a part may be attached on top of that. This makes it easier to remove the part. In this case, the shape of the sticker 2 may be circular, square, rectangular, triangular, etc., and each may have rounded corners or may be designed to match the shape of the part to be attached. Note that a top coat may be applied on the sticker 2 and the part may be attached using its adhesiveness, or the decorative surface 201 of the sticker 2 may also contain an adhesive substance, and the part may be attached to the adhesive substance of the decorative surface 201, and then a top coat may be applied on top of that.
