Gel nail sticker {Gel nail sticker}

The present invention relates to a gel nail sticker, and more particularly, it is possible to omit the PET film, which has been indispensable in the past, and to prevent foreign substances, scratches, etc. during use, and a new construction that is easy to stick to curved nails. Is about gel nail stickers.

In general, in the case of nail art, a method of applying pigments such as nail polish of various colors and the like to nails and toenails is applied.

However, such a method of applying a liquid pigment takes a long time to cure after the pigment is applied causes a user inconvenience. In the case of the nail art, it is not easy to draw directly, and in many cases, a person spends a high cost separately and receives a service. In the above case, various shapes or letters printed on the nail may be changed depending on frequent hand washing. As a result of this, the problem has been raised that the effect is insignificant compared to the high expenditure.

Meanwhile, gel nail stickers that can be attached to nails have been released and used.The gel coating layer, which is the top layer of gel nail stickers, sticks to the wrapping paper during distribution, so that the gel nail stickers fall off the release paper and do not use gel nail stickers properly. There was no problem.

In order to solve this problem, a product having a PET film such as a vinyl film attached to the gel coating layer, which is the uppermost layer, has been released and used. However, since the PET film needs to be further provided, a lot of manufacturing time and manufacturing time are required. When the gel nail sticker is used, the PET film must be peeled off, and thus there is a problem such as troublesome use.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The objects, features and advantages of the present invention will be more readily understood by reference to the accompanying drawings and the following detailed description. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

In addition, in describing the component of this invention, terms, such as 1st, 2nd, A, B, (a), (b), can be used. These terms are only for distinguishing the components from other components, and the nature, order or order of the components are not limited by the terms. For example, if a component is described as being "connected", "coupled" or "connected" to another component, that component may be directly connected or connected to that other component, but between each component. It is to be understood that another component may be "connected", "coupled" or "connected".

Referring to the drawings, the gel nail sticker according to the present invention includes a base film 20, an adhesive layer 22 provided on the base film 20, and a color layer 24 provided on the adhesive layer 22. And a UV gel coating layer 26 provided on the color layer 24 and an LED gel coating layer 28 provided on the UV gel coating layer 26.

An adhesive is applied on the base film 20 to form an adhesive layer 22. In the present invention, the base film 20 may employ a PET film. An adhesive is applied to the PET base film 20 to a predetermined thickness. In this case, various adhesives that are already commonly used as the adhesive may be applied. The bottom surface of the base film 20 may be provided with a lower adhesive layer coated with an adhesive. The bottom surface of the base film 20 may be provided with a release paper layer that is temporarily attached to the lower adhesive layer. The release paper is temporarily attached to the lower adhesive layer to protect the lower adhesive layer on the bottom surface of the base film 20 by the release paper layer.

Color ink is printed on the base film 20 to a predetermined thickness. To be precise, the color layer 24 is formed in the adhesive layer 22 on the base film 20. At this time, the color ink is CMYK, etc., C is blue, M is red, Y is yellow, K is black, the color layer 24 in a variety of ways, such as appropriately mixed or used alone such color inks To form. The color layer 24 may be formed by applying offset printing or silk screen printing. The color layer 24 may be printed to have a nail shape. Alternatively, the color layer 24 may be printed to have a claw shape. At this time, before forming the color layer 24, white ink is first applied on the base film 20 (exactly, the adhesive layer 22), and then the color layer 24 is printed by printing color ink on the white ink layer. Form. The white ink layer 23 is formed on the adhesive layer 22 applied on the base film 20, and the color layer 24 is formed on the white ink layer 23. As described above, color inks mixed with CMYK or mixed with other colors may be painted on the white ink layer 23 to produce a color desired to be expressed in the gel nail sticker. By forming the color layer 24 on the white printed layer, the color of the color layer 24 is outstanding. White print layers are optional.

The UV gel coating layer is coated on the color layer 24 to form a UV gel coating layer 26. Since the UV gel coating layer 26 is in a liquid form that is not dried, the UV gel coating layer 26 is hardened by drying the UV gel coating layer 26 to cure the UV gel coating layer 26. At this time, the UV gel coating liquid is formed by mixing an oligomer, a monomer, a short wavelength initiator. 40% to 60% of the oligomer, 30% to 55% of the monomer, and 2% to 10% of the short wavelength initiator are mixed to form a UV gel coating liquid. Oligomers are urethane and acrylic epoxy polyester series oligomers. In this case, the printing layer may be formed on the color layer 24, and the UV coating layer 26 may be formed on the printing layer. The printed layer may be printed by applying or adding various materials for aesthetics such as pattern expression, mica, and fine particles. As a printing method for forming the printed layer, various printing methods such as silk screen printing, flexographic printing, and gravure printing may be applied. Of course, the printed layer may be omitted as necessary.

When the oligomer is above the reference value (i.e. when the content of the oligomer exceeds 60%) the gel nail sticker is too soft (soft) product (herein, the product means a gel nail sticker, hereinafter for convenience gel nail) It is to be understood that the sticker is sometimes referred to as a product.) The deformation of the product and the scratches, stamps, etc. of the product may occur, resulting in a poor holding force. Therefore, it is necessary to mix so that the content of the oligomer does not exceed 60%. In addition, when the oligomer is below the reference value (i.e., when the content of the oligomer is less than 40%), the gel nail sticker becomes too hard to be attached to the curved nails of the general consumer. This results in a drop in adhesion, which causes the gel nail sticker to break away (falling from nails or toenails) and lack of fit, resulting in shape deformation. Thus, the content of the oligomer is mixed to 40% or more.

When the monomer exceeds 55% of the content exceeding the reference value, the flexibility and elongation of the product is lowered, the adhesion to the curved nails (adhesive force) is lowered and the sustainability is much lowered. In addition, if the content of the monomer is less than 30% that does not meet the standard value, the gel nail sticker becomes so hard that the adhesion (adhesive strength to nails or toenails) is lowered when the adhesion to the curved nails decreases (adhesion to nails or toenails). It is important to set the monomer in the 30 to 55% range.

At this time, the adhesion means that the lower adhesive layer provided under the base film 20 in the gel nail sticker is properly attached to the user's curved nails or toenails without falling off. By improving the adhesion of the lower adhesive layer, it can be said that the gel nail sticker is excellent in adhesion to the nail (or toenail).

When the short wavelength initiator is more than 10%, the curing state of the product is so fast that natural curing can be achieved during the manufacturing and distribution process, so it is difficult to attach the gel nail sticker to the curved nails or toenails of the user, Or peel from the toenails. To prevent this, mix the short wavelength initiator so that it does not exceed 10%. In addition, when the short wavelength initiator is less than 2% that does not meet the reference value, the curing speed is too slow and the firmness of the product is lost. Because of this, it gets on your hands and easily sticks to other foreign objects. Product variants also come easily. Of course, sustainability is also reduced. It is therefore important to adjust the content so that the content of the short wavelength initiator is 2% or more.

On the other hand, the UV gel coating layer 26 may be uniformly formed on the UV gel coating layer 26 by applying the UV gel coating liquid several times in a thin thickness and performing the drying process several times each time the UV gel coating liquid is applied. . The UV gel coating layer 26 may be referred to as a transparent coating layer that protects the color layer 24 as a transparent coating layer. Meanwhile, in the present invention, for the drying of the adhesive layer 22, the color layer 24, and the UV gel coating layer 26 provided on the base film 20, UV drying and hot air drying are simultaneously performed. When the yuv is dried only, the adhesive layer 22 and the colored layer may not dry properly because the color layer 24 and the adhesive layer 22 in the lower layer may not be dried even though the yuv gel coating layer 26 is dried. The 24 and the UV gel coating layer 26 may be configured to perform hot air drying at the same time as the UV drying. UV drying and hot air drying may be performed together to prevent peeling of the UV gel coating layer 26, the color layer 24, and the adhesive layer 22.

The LED gel coating layer 28 is provided on the UV gel coating layer 26. The LED gel coating layer 28 is formed by applying an LED gel raw material to a predetermined thickness on the UV gel coating layer 26. The LED gel coating layer 28 is also configured to protect the color layer 24 together with the UV gel coating layer 26 as a transparent coating layer. The unique color of the gel nail sticker is emitted from the color layer 24 and the UV gel coating layer 26 and the LED gel coating layer 28 protect the color layer 24. On the other hand, the LED gel coating liquid for forming the LED gel coating layer 28 is formed by mixing a monomer, an oligomer, a long wavelength initiator, cellulose. LED gel coating liquid is formed by mixing 20-30% of monomer, 15-40% of oligomer, 0.1-0.5% of long wavelength initiator, and 30-55% of cellulose.

If the monomer exceeds 30% of the content exceeding the reference value, the stickiness of the product is too severe, the physical properties of the product itself is poor in firmness. The product gets on your hands and the shape of the product is broken. The rate of curing of the product is also greatly reduced. Contacting the product by hand means that the LED gel coating layer 28 is buried in the hand. To prevent this, the monomer content is set to 30% or less, which does not exceed the reference value. In addition, when the content of the monomer is less than 20%, the gel nail sticker becomes too hard, and when the gel nail sticker is attached to the curved nail, the adhesion decreases and the sustaining force is lowered. Thus, the content of monomer is made 20% or more.

When the oligomer exceeds 40%, it tends to be easily cured by ultraviolet light at room temperature and in real life. Natural curing is easily achieved during manufacturing and distribution. Due to this, when the consumer removes the gel nail sticker after curing the LED gel coating layer 28, it is not completely removed and is peeled off. This will make it difficult to remove the gel nail sticker from your nails and cause damage and strain on your nails. If the oligomer is less than 15%, the curing rate becomes too slow during UV curing. If the curing speed is too slow and the product is not cured properly, the uncured product can be damaged. Lowering the lasting force due to shape deformation, glossiness deterioration, and sticking of foreign substances.

When the long wavelength initiator is more than 0.5%, it is easily cured by exposure to room temperature real life light. Natural curing takes place in the manufacturing and distribution processes. Then, it is difficult to attach the gel nail sticker easily to the user's curved nails or toenails and the gel nail sticker may easily fall off from the nail or toenail even after being attached. If the long wavelength initiator is less than 0.1% which does not meet the reference value, the curing speed is too slow and the product is not firm. Because of this, it gets on your hands and easily sticks to other foreign objects. Product variants also come easily. Of course, sustainability is also reduced.

When the cellulose is mixed to exceed 55%, the elongation of the gel nail sticker is so low that it is not easy to attach to curved nails (or toenails). In the gel nail sticker, the LED gel coating layer 28 is before curing, but the gel nail sticker is a product before curing, but the gel nail sticker is in a hard state. Therefore, the product must be flexible and elongated to be easy to attach to curved nails. However, when the cellulose is mixed to exceed 55% and attaches too hard products, the nails (or toenails) are not completely adhered and fall off easily, so that the adhesion and sustainability of the gel nail sticker are reduced. Thus, the cellulose is mixed so that it is 55% or less.

The monomer, oligomer, and long wavelength initiator are all liquid products. They all have to give ultraviolet light to turn the liquid state into a solid. The liquid gel gel sticker has a function of making the cellulose semisolid.

If the content of the cellulose is less than 30%, the function of making the gel nail sticker semi-solid state is insufficient, so that the cellulose content is more than 30%.

Meanwhile, in the present invention, the adhesive layer 22, the color layer 24, the UV gel coating layer 26, and the LED gel coating layer 28 formed on the base film 20 by the punching process are formed in the shape of nails (or toenails). It can be configured to. In the punching process, the other layers except the base film 20 are cut into a nail (or toenail) shape. The remaining layers mean the adhesive layer 22, the color layer 24, the UV gel coating layer 26, and the LED gel coating layer 28. After the punching process, the base film 20 may be cut to further cut a gel nail sticker. In such a cutting process, the gel nail sticker formed in the shape of a nail (or toenail) is cut into a strip shape provided in plurality on the base film 20. Such a cut product may be referred to as a gel nail strip. That is, the gel nail strip is provided with a plurality of gel nail stickers. In the present invention, the gel nail strip may be cut so that approximately 5 to 10 gel nail stickers are provided.

At this time, the LED gel coating layer 28 is configured to dry the light having a longer wavelength than the UV gel coating layer 26. For example, the UV gel coating layer 26 is dried in a gel nail production plant, and the LED gel coating layer 28 is a gel nail sticker user attaches a gel nail sticker to a nail or toenail to dry the UV gel coating layer 26. It may be allowed to dry with light having a wavelength longer than that of. The LED gel coating layer 28 may be dried by the LED light having a wavelength longer than the ultraviolet light for drying the UV gel coating layer 26.

Therefore, the gel nail sticker according to the present invention is characterized in that the product is complemented to increase the durability and the feeling of use compared to the conventional. Hardening the gel nail sticker to create a hard feeling, scratches, stamping parts that take a real life when used, the present invention has the effect of further enhancing the sustainability by supplementing to avoid the foreign matter, scratches, stamping parts take place in real life. The product is uncured (specifically, the LED gel coating layer 28 is uncured), which is quite flexible and soft. The color layer 24 and the UV coating layer are cured to be less flexible than the LED gel coating layer 28, and the LED gel coating layer 28 is very flexible and soft. Therefore, it is easy to stick to the curved nails (or toenails) of the general public. The LED gel coating layer 28 is a semi-flexible and flexible state that is easy to attach to the curved nails (or toenails) of the general public. When the LED gel coating layer 28 is cured (cured with a long wavelength LED light) after the work is attached to the nail (or toenail), it is hardened in that state so that the sustainability can be improved.

In the above, the specific Example of this invention was described above. However, the spirit and scope of the present invention is not limited to these specific embodiments, and various changes and modifications can be made without departing from the spirit of the present invention. Those who have it will understand.

Therefore, since the embodiments described above are provided to completely inform the scope of the invention to those skilled in the art to which the present invention pertains, it should be understood that they are exemplary in all respects and not limited. The invention is only defined by the scope of the claims.
