Gel nail sticker manufacturing method {

The present invention relates to a method of manufacturing a gel nail sticker, and more particularly, to a gel nail sticker which can prevent the occurrence of foreign objects, scratches, and the like when using a gel nail sticker, To a method for manufacturing a nail sticker.

Generally, in case of nail art, a method of applying pigments such as nail polish of various colors to nails and claws is applied.

However, such a method of applying the liquid pigment is time consuming for curing after applying the pigment, which causes the user to feel inconvenience. In the case of the nail art, it is difficult for the user to directly draw the nail art. Therefore, the nail art user often spends a high cost and receives a service separately. In such a case, the nail art may have various shapes and characters printed on the nail The problem is that the effect is insufficient compared to high cost expenditure.

Meanwhile, a gel nail sticker that can be attached to a nail has been introduced and used. The gel coat layer on the top of the gel nail sticker is attached to the wrapping paper in the circulation, so that the gel nail sticker is separated from the release paper. There was a problem that I could not do.

In the case of Korean Registered Patent No. 10-1728432 (registered on Apr. 13, 2017) (hereafter referred to as registered patent), there is a step of applying ink to a base film by a printing method, a step of applying a UV coating liquid to the ink applied to the base film (PET film) to the base film so as to cover the ink and the UV coating liquid; pressing the base film with the PET film with the pressing roller; and pressing the nail A sticking step of passing the sticker through a UV drier, a step of removing the PET film from the base film, and a punching step of punching the nail sticker from which the PET film has been removed to a predetermined size, Wherein the ink is in a wet state in which the ink is not dried.

However, since the PET film needs to be peeled off from the PET film when it is used after being pressed with the pressing roller, the PET film has a large number of manufacturing steps, requires a long time for manufacturing, and is troublesome in use.

In addition, there is a problem that the gel nail sticker is hardened due to the hardness of the gel nail sticker and the gel nail sticker is poor in flexibility, so that the gel nail sticker is hardened and sticks to the curved nail of the general public There is a drawback that it is not easy.

Domestic Registration No. 10-1728432 (Registered on Apr. 13, 2013) Korean Registered Patent No. 10-1240508 (Registered on February 28, 2013) Korean Patent Laid-Open No. 10-2017-0018649 (published on Feb. 20, 2017)

It is an object of the present invention to solve the problem of reducing the number of manufacturing processes and to solve the problem of a long manufacturing time and to omit the PET film that has become a necessity in the past and to prevent the occurrence of foreign objects and scratches during actual use, And to provide a gel nail sticker which is easily attached to a curved nail.

The method of manufacturing a gel nail sticker according to the present invention includes the steps of forming an adhesive layer 22 on a base film 20 and forming an adhesive layer 22 on the adhesive layer 22 on the base film 20, A coloring layer forming step of applying a coloring layer 24 to the coloring layer 24 and a UV coating layer 26 having a UV coating layer 26 on the color layer 24 and a UV coating layer 28 on the UV coating layer 26, And an LED gel coating layer forming step of forming an LED gel coating layer. The gel nail sticker manufactured by the present invention comprises a base film 20, an adhesive layer 22 provided on the base film 20, a color layer 24 provided on the adhesive layer 22, A UV coating layer 26 provided on the color layer 24 and an LED gel coating layer 28 provided on the UV coating layer 26.

An adhesive is applied on the base film 20 to form an adhesive layer 22. [ In the adhesive layer forming step, the adhesive layer 22 is formed by applying an adhesive on the base film 20 to a predetermined thickness and curing the adhesive layer. The adhesive applied on the base film (20) is dried to cure the 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) at a predetermined thickness. At this time, various adhesives that have been conventionally used can be applied as the adhesive. And a lower adhesive layer 22 formed by applying an adhesive to the bottom surface of the base film 20. A release layer may be provided on the bottom surface of the base film 20 to adhere to the lower adhesive layer 22. A release paper is attached to the lower adhesive layer 22 to protect the lower adhesive layer 22 on the bottom surface of the base film 20 by the release paper layer.

The color ink is printed on the base film 20 to a predetermined thickness. The color layer 24 is formed on the adhesive layer 22 on the base film 20 precisely. At this time, as the color ink, CMYK or the like is used. C is blue, M is red, Y is yellow, and K is black. The color layer 24 is formed in various ways such that these color inks are appropriately mixed, . The color layer 24 may be formed by applying offset printing or silk screen printing. The color layer 24 may be printed so as to have a nail shape. Or the color layer 24 may be printed to have a claw shape. In the color layer forming step, color ink is printed on the adhesive layer 22 provided on the base film 20 to a predetermined thickness and then dried to form a color layer 24.

At this time, in the present invention, the step of forming the white ink layer 23 for applying the white ink to the base film 20 is performed first before the color layer forming step, and the color ink is printed on the white ink layer 23 The color layer 24 may be formed. The white ink is first coated on the base film 20 (more precisely, the adhesive layer 22) before the color layer 24 is formed, and then the color ink is printed on the white ink layer to form the color layer 24 do. A white ink layer 23 is formed on the adhesive layer 22 applied on the base film 20 and a color layer 24 is formed on the white ink layer 23. [ As described above, it is possible to mix CMYK or other color-mixed color ink on the white ink layer 23 to give a color to be expressed in the gel nail sticker. The color layer 24 is formed on the white printing layer so that the color of the color layer 24 becomes visible. The step of forming the white ink layer 23 for forming the white print layer may be performed or is optional. When the white ink layer 23 is formed on the adhesive layer 22 applied on the base film 20 in the step of forming the white ink layer 23, the color layer 24 is formed on the white ink layer 23 If the white ink layer 23 is not formed, the color layer 24 is formed on the adhesive layer 22 formed on the base film 20.

A UV coating layer 26 is formed on the color layer 24 by applying a UV coating layer having a predetermined thickness. In the step of forming the UV coating layer, the UV coating layer 26 is coated on the color layer 24 to a predetermined thickness, and then the UV coating layer is dried to form the UV coating layer 26. Since the Uva gel coating layer 26 is in a non-dried liquid form, the Uva gel coating layer 26 is dried to cure the Uva gel coating layer 26, thereby hardening the Uva gel coating layer 26. At this time, the UV coating liquid is formed by mixing an oligomer, a monomer, and a short wavelength dispersing agent. 40 to 60% of an oligomer, 30 to 55% of a monomer, and 2 to 10% of a short wavelength are mixed to form a UV coating liquid. The oligomers are urethane, acrylic epoxy polyester series oligomers. At this time, a printing layer may be formed on the color layer 24, and a UV coating layer 26 may be formed on the printing layer. The printing layer can be printed by applying or adding various materials for esthetics such as pattern expression, mica, and fine particles. As a printing method for forming the printing layer, various printing methods such as silk screen printing, flexographic printing, and gravure printing can be applied. Of course, the printing layer may be omitted if necessary.

When the oligomer is above the reference value (i.e., when the oligomer content exceeds 60%), the gel nail stitch is so soft that the product (here, the product refers to a gel nail sticker, It is understood that the sticker may be referred to as a product), and the product is subject to many scratches and scratches, resulting in deterioration of the holding force. Therefore, it is necessary to mix such that the content of oligomer does not exceed 60%. Further, when the oligomer is below the reference value (that is, when the oligomer content is less than 40%), the gel nail sticker becomes too hard and is hard to stick to the curved nail of the general consumer. Thus, the adhesion feeling (adhesion) is lowered, and the gel nail sticker is separated from the nail or the toenails, and there is no adhesion (adhesion), resulting in shape deformation. Thus, the mixture is mixed so that the content of the oligomer becomes 40% or more.

When the content of the monomer exceeds 55%, which is a content exceeding the reference value, the flexibility and elongation of the product are lowered, and the adhesion (adhesion) to be attached to the curved nails is lowered and the sustaining force is lowered. If the content of the monomer is less than 30% which is less than the standard value, the gel nail sticker becomes too hard and adheres to the curved nail when the nail sticking property is lowered and the durability is lowered, so that the monomer is adjusted to a range of 30 to 55% It is important.

If the short-wavelength broadcasting agent is more than 10%, the cured state of the product becomes too fast, so that natural curing can be performed during the manufacturing process and circulation process, so that even if it is difficult to attach the gel nail sticker to the bent nail or claw of the user, Or from the nail. To prevent this, please do not exceed 10% of the short wavelength. In addition, if the short wavelength is less than 2%, which is below the standard value, the curing rate is too slow and the robustness of the product is lost. Because of this, it gets buried in your hands and other foreign matter sticks easily. Product changes easily come. Of course, the sustainability also decreases. It is therefore important to adjust the content so that the content of the short wavelength dispersant is at least 2%.

Meanwhile, in the step of forming the UV coating layer, the UV coating layer may be applied several times in a thin thickness and the UV coating layer 26 may be formed uniformly by performing the drying process several times each time the UV coating is applied. It may be better to apply multiple times, and then dry each time, rather than applying a thick coat of Uva gel coating at once. The UV coating layer 26 may be a transparent coating layer that protects the color layer 24 as a transparent coating layer. Meanwhile, in order to dry the adhesive layer 22, the color layer 24, and the UV coating layer 26 provided on the base film 20, the UV drying and the hot air drying are simultaneously performed. Since the color layer 24 and the adhesive layer 22 in the lower layer may not be dried properly even if the drying is carried out until the UV coating layer 26 is dried, The drying of the UV-curing coating layer 24 and the UV-curing coating layer 26 may be performed simultaneously with the UV drying. The UV-drying and the hot-air drying may be simultaneously performed to prevent the peeling of the UV-visible coating layer 26, the color layer 24, and the adhesive layer 22.

An ELD gel coating layer 28 is provided on the UV-visible coating layer 26. The ELID gel coat layer 28 is formed by applying an ELID gel material to the ELVID gel coat layer 26 to a predetermined thickness. The LED gel coating layer 28 may be formed by applying an LED gel material to the UV coating layer 26 to a predetermined thickness in the LED gel coating layer forming step. The LED gel coat layer 28 is also configured to protect the color layer 24 together with the UV coat layer 26 as a transparent coating layer. The inherent hue of the gel nail sticker is released from the color layer 24 and the UV coat layer 26 and the LED gel coat layer 28 protect the color layer 24. The ELD coating solution for forming the ELD gel coating layer 28 is formed by mixing a monomer, an oligomer, a long wavelength dispersing agent, and cellulose. 20 to 30% of a monomer, 15 to 40% of an oligomer, 0.1 to 0.5% of a long wavelength, and 30 to 55% of a cellulose are mixed to form an ELID gel coating solution.

If the content of the monomer exceeds 30%, which exceeds the reference value, the stickiness of the product is too high and the physical properties of the product itself are poor. The product is buried in the hand and the product form is destroyed. The curing speed of the product is greatly reduced. When a product is put on the hand, it means that an LED gel coat layer 28 is buried in the hand of the product. In order to prevent this, the content of the monomer is adjusted to 30% or less which does not exceed the standard value. In addition, if the monomer content is less than 20%, the gel nail sticker becomes too hard, and when the gel nail sticker is attached to the bent nail, the adhesion is lowered and the sustainability is lowered. Therefore, the content of the monomer should be 20% or more.

Here, the adhesive force means that the lower adhesive layer 22 provided under the base film 20 in the gel nail sticker is firmly attached to the curved nail or the toenails of the user. The adhesion of the gel nail sticker to the fingernail (or claw) is improved by improving the adhesion of the lower adhesive layer 22.

If the amount of the oligomer exceeds 40%, it tends to be cured easily at room temperature and in real life by ultraviolet light. Natural hardening is easily achieved in the manufacturing process and the distribution process. Therefore, when the gel nail sticker is removed after the curing process of the LED gel coat layer 28, the consumer can not completely remove it, and the gel is peeled off. Then, it is difficult to remove the gel nail sticker from the fingernail, and the fingernail is damaged and crowded. If the oligomer content is less than 15%, the curing rate during ultraviolet curing becomes too slow. If the curing speed is too slow and the product is not properly cured and used as it is, the gel nail stigma will be damaged. The shape is deformed, the glossiness is lowered, and the foreign matter adheres.

If the wavelength of the long wavelength broadcast exceeds 0.5%, it is easily exposed to room temperature real-life light to be cured. Natural curing takes place in the manufacturing process and in the distribution process. Then, it is difficult to easily attach the gel nail sticker to the user's curved nails or claws, and the gel nail sticker can easily fall off the nails or toenails after the sticking. If the long wavelength is less than 0.1%, which is below the standard value, the hardening rate is too slow and the product is not robust. Because of this, it gets buried in your hands and other foreign matter sticks easily. Product changes easily come. Of course, the sustainability also decreases.

If the cellulose is mixed in excess of 55%, the stretch of the gel nail sticker is too low to be easily attached to the curved nail (or claw). In the gel nail sticker, the gel coat layer (28) is not cured, so the gel nail sticker is a product before curing but the gel nail sticker is in a hard state. Therefore, it is easy to attach to the bent nail when the product is flexible and elongated. However, when the cellulose is mixed in an amount exceeding 55% and the product is attached too hard, the nail (or claw) is not completely adhered to the nail, so that the adhesive nail sticker is deteriorated in adhesion and durability. Thus, the cellulose is mixed so as to be 55% or less.

The monomer, oligomer, and long wavelength dispersing agent are all in liquid state. All of these must be exposed to ultraviolet light before they become solid. This gel nail sticker in liquid state functions to make the cellulose into a semi-solid state.

If the content of the cellulose is less than 30%, the function of rendering the gel nail sticker semi-solid is insufficient, so that the cellulose content is set to 30% or more.

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 are formed into a nail (or claw) shape by the punching process in the present invention. . The other layers except for the base film 20 are cut into nails (or claws) in the punching process. The remaining layer means the adhesive layer 22, the color layer 24, the UV coating layer 26, and the ELD gel coating layer 28. A cut process of cutting the gel nail sticker by cutting the base film 20 after the punching process can be further performed. In this cutting process, a gel nail sticker formed into a nail (or claw) shape is cut into a plurality of strips provided on the base film 20. These cutting products can be called gel nail strips. That is, the gel nail strip is provided with a plurality of gel nail stickers. In the present invention, the gel nail strip can be cut to have about 5 to about 10 gel nail stickers.

At this time, the LED gel coat layer 28 is configured to dry with light longer in wavelength than the UV coat layer 26. For example, the UV coating layer 26 may be dried at a gel nail production facility or the like and the LED coating layer 28 may be formed by a gel nail sticker user attaching a gel nail sticker to a nail or toenails, It is possible to dry the light with a relatively longer wavelength than the wavelength of the light. The ELD gel coating layer 28 may be dried with LED light having a wavelength longer than that of the IR light for drying the UV coating layer 26.

Accordingly, the method of manufacturing a gel nail sticker according to the present invention is characterized in that it is possible to provide a gel nail sticker that is a complementary product to enhance the sustainability and feeling of use. The gel nail sticker is cured to harden the product, resulting in a foreign body feeling, a scratch, and a stained portion which are exposed to real life. In the present invention, the effect of enhancing the durability is improved by complementing the product so as not to create a foreign body feeling, scratch, have. The product is extremely soft and soft because the product is in an uncured state (specifically, the LED gel coat layer 28 is in an uncured state). 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 soft and soft. Therefore, it is easy to attach to a curved nail (or claw) of a general person. Since the ELID gel coating layer 28 is semi-hardened and flexible, it is easy to attach to the curved nails (or claws) of a general person. When the LED gel coat layer 28 is hardened (cured by long wavelength LED light) after being attached to the nail (or claw), there is no hardening, scratching, deformation, etc. in the state and the sustainability can be improved.
