The present invention relates to a gel nail sticker and a method of manufacturing the gel nail sticker. More particularly, the present invention relates to a gel nail sticker which is cured to a solid state upon irradiation with ultraviolet rays after attaching to a nail and a method for manufacturing the same.

As one of the ways of expressing the physical beauty pursued by human beings, the beauty industry is becoming more and more developed at the same time. Especially after the rapid expansion of the market since the 20th century, the beauty industry has become popular to the general public. Among the beauty industry, nail art is rapidly becoming an essential element of expressive art to the body regardless of age and gender.

Originally, nail art is a field of beauty art, which is one of the ways to make a human body beautiful, and the way, shape or color of nail has been expressed reflecting the change and value of culture of the age.

Conventional nail art is mainly applied to nails or toenails such as various colored nail polish. However, such a method of applying the liquid pigment not only takes a long time to dry the pigment, but also causes the user to feel inconvenience because the durability after drying is very low.

In recent years, ultraviolet gel nails have been spotlighted in which UV curable resins are incorporated into pigments, coated on nails or toenails, and then hardened using a UV lamp.

The UV gel is advantageous in that it is cured using ultraviolet rays and has various advantages. The UV gel has the advantage of being not easily broken because it is soft and soft, and is not discolored even when exposed to the sunlight and has excellent gloss. Is applied to natural nail and UV-cured, so that natural nail can be made glossy and shiny and has a sjffl effect.

However, in spite of these merits, when a UV gel layer is directly formed on a natural nail, it is necessary to immerse a finger for a long time in a harmful solvent in order to remove it, so that it is very harmful to skin and nails, Damage to natural nails has become a serious problem after detaching. In addition, there is a disadvantage that the opposite end of the cuticle is chipped or the end portion of the cuticle is peeled.

As another type of nail art, a dry nail sticker has been developed to overcome the problems of liquid waxes such as nail polish and UV gel, but it is a film composed of the same raw material as most nail polish and has a large durability after attachment There is a problem.

Some artificial nails have excellent durability, but they lack flexibility and stretchability. Therefore, it is not easy to sit on the fingernail because it is not fit and adhered to the fingernail, resulting in a loss of aesthetics and a drawback that the artificial nail falls off from the fingernail.

The lower gel layer may be softened before curing, but harder than the upper gel layer after curing.

The upper gel layer is less flexible than the lower gel layer before curing to reduce the stickiness of the surface, and the oxygen contact of the lower gel layer may be blocked to improve the degree of curing of the lower gel layer upon irradiation with ultraviolet light.

The lower end joint portion may include a color layer and an adhesive layer.

The color layer contains a pigment having color and can maintain softness regardless of ultraviolet irradiation.

The adhesive layer is a portion directly attached to the nail or toenails, and is located under the color layer, and may have adhesiveness.

In addition, the bottom end portion may have various designs, and may further include a printing layer printed on the color layer.

The upper end joint portion may further include a protective film for protecting the outermost surface, and the lower end joint portion may further include a release sheet for preventing contamination of the nail or the toenails with foreign substances before attachment.

Here, the protective film may include an ultraviolet shielding material to prevent the upper end joint portion from being hardened by ultraviolet rays included in natural light.

Meanwhile, the method of manufacturing a gel nail sticker according to an embodiment of the present invention includes steps of forming a top joint portion, forming a bottom joint portion, and forming a gel nail sticker.

The foregoing summary, as well as the detailed description of the preferred embodiments of the present application set forth below, may be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there are shown preferred embodiments in the figures. It should be understood, however, that this application is not limited to the precise arrangements and instrumentalities shown.

2 is a cross-sectional view along the line A-A 'in Fig. 1;
3 is a flowchart illustrating a process of nail art using a gel nail sticker according to an embodiment of the present invention; And
4 is a flowchart illustrating a method of manufacturing a gel nail sticker according to an embodiment of the present invention.

Hereinafter, a gel nail sticker according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

1 is a plan view showing a gel nail sticker according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line A-A 'of FIG.

1 and 2, the gel nail sticker according to an embodiment of the present invention includes a lower end joint part 200 and an upper end joint part 100. [

The lower joint portion 200 is a portion directly attached to the nail or the nail and has a color or a pattern and is formed of a soft material so as to correspond to the curved surface of the nail or the nail.

The top end joint part 100 is a transparent coating layer which is located on the upper end of the lower end joint part 200 and imparts gloss to the color or pattern of the lower end joint part 200, It is a soft semi-solid state so that it can correspond to a curved surface. When attached to a nail or a toenail and irradiated with ultraviolet rays, it hardens in a solid state while maintaining the shape attached to the nail or toenails.

That is, before the gel nail sticker of the present embodiment is irradiated with ultraviolet light, the entire gel can be adhered to the nail so as to correspond to the curved surface of the nail. After irradiating ultraviolet rays, the lower leg joint part 200 maintains the same physical properties as the gel, but has the same properties as the gel. However, the upper end joint part 100 is hardened in a solid state to impart firm physical properties to the gel nail sticker, And the durability can be improved.

Further, the gel nail sticker of this embodiment can be removed by a nail remover. The nail remover may be an acetone-free remover not including acetone, and the acetone-free remover may also remove the gel nail sticker of the present embodiment like acetone by using the acetone-free remover. .

More specifically, the upper end joint part 100 includes an upper gel layer 110 and a lower gel layer 120. The lower end joint part 200 includes a print layer 220, a color layer 210, and an adhesive layer 230, . ≪ / RTI > That is, the gel nail sticker of the present embodiment may be formed by stacking an upper gel layer 110, a lower gel layer 120, an anchor layer, a color layer 210, and an adhesive layer 230 in this order.

First, the upper gel layer 110 is located at the uppermost end of the gel nail sticker of the present embodiment and is exposed to the outside when attached to the nail or toenails. The top gel layer 110 may include a thermal drying material, a small amount of an ultraviolet curing raw material, a photoinitiator, and an additive. That is, the upper gel layer 110 may be in a state where the thermal drying raw material, the ultraviolet hardening raw material, the photoinitiator and the additive are dissolved in the solvent.

Here, the heat-drying raw material may be a material which is hardly dried by heat, contributes to film formation after drying, and imparts gloss, scratch resistance and breakability. The heat drying raw material may be blended with a plurality of components to exhibit the above-described characteristics.

The ultraviolet curing raw material may be a material that maintains a soft semi-solid state at normal times, and may be a material that is cured to a solid state polymer material by photopolymerization reaction by obtaining energy from an external material upon irradiation with ultraviolet rays.

The ultraviolet curing raw material is present in a liquid state at room temperature before curing and can be dissolved in a solvent and can be dissolved in a solvent together with the above-mentioned heat-drying raw material and then dried.

After drying, the heat drying raw material forms a film film in a solid state, and the ultraviolet curing raw material remains in a liquid state to impart flexibility to the film film. That is, there may be a liquid state ultraviolet curing raw material among the microscopic, solid state heat drying raw materials.

In this embodiment, the ultraviolet curing raw material included in the top gel layer 110 may include a urethane acrylate oligomer and a polyester oligomer.

Here, the urethane acrylate oligomer is an ultraviolet reactive resin and contributes to the soft physical properties before curing the top gel layer 110, and has a soft characteristic after curing. Further, although not dissolved in acetone after curing, since it has a swelling property, the removability by acetone can be improved.

And it is a polyester oligomer or ultraviolet ray reactive resin, which contributes to the flexible physical properties before curing of the gel nail sticker and has a hard characteristic after curing. Therefore, it can contribute to improvement in hardness after curing. Further, after curing, it is not dissolved in acetone, and since it does not swell well, it has a feature of being poor in removability by acetone.

As described above, the two components having different properties can be properly blended to achieve the desired hardness after curing, and the removability by acetone can be appropriately maintained.

Since the top gel layer 110 contains a small amount of ultraviolet curing raw material, the degree of curing is low and it is located on the top of the bottom gel layer 120 containing a large amount of the ultraviolet curing raw material, so that the surface tackiness of the semi-cured film can be reduced .

Since the curing degree of the ultraviolet curing raw material is rapidly lowered upon contact with oxygen, a protective film 130 for protecting the upper gel layer 110 may be provided on the surface of the upper gel layer 110. The protective film 130 may include an ultraviolet shielding material to prevent the ultraviolet curing raw material contained in the top gel layer 110 from being cured by ultraviolet rays contained in natural light.

The photoinitiator is a material that absorbs energy from ultraviolet rays and starts the photopolymerization reaction by applying the energy to the ultraviolet curable material. In this embodiment, the photoinitiator includes trimethylbenzoylphosphinoxide .

In addition, the additive may include a leveling agent which imparts smoothness to the coating surface and imparts a defoaming property, and a defoaming agent which imparts defoaming property.

In this embodiment, Propyl Acetate may be applied as a solvent in which the thermal drying raw material, the ultraviolet curing raw material and the photoinitiator are dissolved. Propyl acetate is the safest organic solvent with very low human health hazards and may be volatilized after drying resulting in less than 1% residual.

In this embodiment, the upper gel layer 110 may be formed to a thickness of 65 m.

The lower gel layer 120 is positioned below the upper gel layer 110 and directly joined to the lower joint part 200. The lower gel layer 120 may include a thermal drying material, an ultraviolet curing raw material, and a photo initiator.

The heat drying raw material, ultraviolet ray hardening raw material and photoinitiator are dissolved in a solvent. The heat drying raw material, ultraviolet ray hardening raw material, photoinitiator and solvent of the lower gel layer 120 may be composed of the same components as those of the upper gel layer 110. Unlike the top gel layer 110, which contains a small amount of ultraviolet curing raw material, the bottom gel layer 120 may comprise a greater proportion of the ultraviolet curing raw material than the top gel layer 110.

As a result, the lower gel layer 120 has a very flexible physical property before curing and has surface stickiness, so that it can be easily attached to the lower joint portion 200 when the lower gel layer 120 is jointed. In addition, the lower gel layer 120 including a large amount of ultraviolet curing raw material is very hard after curing and can contribute to the solid physical properties of the gel nail sticker.

The lower gel layer 120 containing a large amount of the ultraviolet curing raw material may be rapidly reduced in contact with oxygen when it is in contact with oxygen. The ultraviolet curing raw material may be coated with the top gel layer 110 containing a small amount of the ultraviolet curing raw material to prevent contact with oxygen. By doing so, the degree of curing of the lower gel layer 120 can be improved.

In this embodiment, the lower gel layer 120 may be formed to a thickness of 65 mu m.

On the other hand, the color layer 210 may be a state in which a color pigment, an ultraviolet curing raw material and a heat drying raw material are dissolved in a solvent. That is, the color layer 210 is a portion where the color of the gel nail sticker is determined.

In this embodiment, the ultraviolet curing raw material of the color layer 210 may include a polyester oligomer to contribute to the flexible physical properties of the gel nail sticker. The polyester oligomer is the same as that contained in the top gel layer 110.

The thermal drying material and the solvent contained in the color layer 210 are the same components as the thermal drying material and the solvent of the upper gel layer 110, and therefore, a description thereof will be omitted.

However, since the color layer 210 contains a raw material for ultraviolet curing but does not contain a photoinitiator, curing by ultraviolet rays does not occur. Therefore, it contributes most to the flexible physical properties of the gel nail sticker after ultraviolet irradiation, and since the uncured ultraviolet hardening raw material has sticky properties, it can be a base material that gives adhesion to the print layer 220, which will be described later.

In this embodiment, the color layer 210 may be formed to a thickness of 50 mu m.

The print layer 220 may be selectively printed on the color layer 210 as a part of the gel nail sticker of the present embodiment in which various designs and patterns are expressed. That is, the print layer 220 is not formed on the nail sticker having only the color, and the print layer 220 may be formed on the nail sticker having the color and the pattern at the same time.

The printing layer 220 may be formed by any printing method such as silk screen printing, digital printing, gravure printing, stamping printing, glitter printing, vacuum deposition, and the like.

The print layer 220 can be any material that does not impair the physical properties of the color layer 210 and does not contain ultraviolet curing raw material and photoinitiator and is therefore not cured by ultraviolet light.

In this embodiment, the printing layer 220 may be formed to a thickness of 5 to 55 mu m.

The adhesive layer 230 is a portion directly attached to the nail or the nail and is located under the color layer 210 and may be formed of a material having adhesiveness.

Here, since the adhesive layer 230 does not contain a raw material for ultraviolet curing and a photoinitiator, it is not cured upon irradiation with ultraviolet rays.

In this embodiment, the adhesive layer 230 may be formed to a thickness of 30 mu m.

The release layer 240 may be provided on the lower portion of the adhesive layer 230 to prevent contamination by foreign substances.

The configuration of the gel nail sticker according to an embodiment of the present invention has been described above. The components and thicknesses of each layer described above are merely examples and the components and thickness of each layer are not limited to those described above and any component can be applied as long as the properties of each layer can be exhibited. It is also adjustable.

3 is a flowchart illustrating a process of nail art using a gel nail sticker according to an embodiment of the present invention.

3, the gel nail sticker of the present embodiment is first prepared, and the release paper 240 is removed to remove the gel nail sticker from the nail sticker. As described above, according to the gel nail sticker of the present invention, Or after attaching to the toenails, the upper protective film 130 may be removed, and the nail or the part of the nail removed may be cut using a nail. When the gel nail sticker attached to the nail or toenails is irradiated with ultraviolet rays for a predetermined time, the upper joint portion 100 is hardened and the nail art can be completed.

Therefore, it takes much time to complete the nail art while maintaining the durability and esthetics of the conventional gel nail, and since the procedure is very simple, the nail art can be easily performed even for the beginner. Also, self-nail art can be done without visiting the nail shop, which saves time and money.

In addition, since it can be removed by acetone, which is a component of a general nail remover, damage to nails, toenails and skin around the nails can be minimized.

Thus, the structure and effect of the gel nail sticker of the present embodiment have been described.

Hereinafter, a method of manufacturing a gel nail sticker according to an embodiment of the present invention will be described with reference to FIG.

4 is a flowchart illustrating a method of manufacturing a gel nail sticker according to an embodiment of the present invention.

4, a method of manufacturing a gel nail sticker according to an embodiment of the present invention includes forming a top joint part S100, a bottom joint part S200, and a gel nail sticker S300 .

The upper joint portion forming step S100 includes an upper gel layer forming process P110, a lower gel layer forming process P120, and a first joining process P130.

In the upper gel layer formation process (P110), an ultraviolet curing raw material, a photoinitiator, a heat drying raw material and an additive dissolved in a solvent are dried under a predetermined temperature and time condition to form a top gel layer by filming. In the upper gel layer formation process (P110), the upper gel layer roll may be formed by winding the filmed upper gel layer.

In the lower gel layer formation process (P120), a higher ratio of the ultraviolet curing raw material, the photoinitiator and the heat drying raw material than the upper gel layer dissolved in the solvent is dried under a predetermined temperature and time condition to form a lower gel layer .

In the first laminating step P130, the upper gel layer and the lower gel layer are laminated to each other by applying a pressure under a predetermined temperature condition to form an upper end joint portion.

For example, in the first joining step (P130), the lower gel layer formed in the lower gel layer forming step is wound on a roll of the upper joint roll. At this time, the end of the upper gel layer wound on the upper gel layer roll is wound along with the lower gel layer, It can be connected to a roll and wound. As a result, the upper gel layer roll is rotated in the opposite direction, and the upper gel layer wound thereon is unwound and wound together with the lower gel layer on the upper upper part roll, and can be joined to each other.

The lower step portion forming step S200 includes a color layer forming process S210 and a second lamination process S230.

In the color layer forming process (S210), a composition in which the ultraviolet curing raw material, the heat drying raw material, and the pigment having color are mixed is formed into a film to form a color layer as a background color of the gel nail sticker.

After forming the color layer in the color layer formation process (S210), a print layer formation process (S220) may be further performed in which a pattern is printed on the top of the color layer to form a print layer. The print layer forming process (S220) is performed only when a gel nail sticker in which a pattern is formed is formed. In the case of producing a gel nail sticker having only a color without a pattern, a print layer forming process (S220) may be omitted.

In the second lamination process (S230), the adhesive layer having adhesive property is wound together with the color layer with a predetermined tension to bond them together.

The gel nail sticker forming step S300 includes a third joining step P310.

In the third joint pouching process (P310), the upper end joint portion and the lower end joint portion are lapped under a certain temperature to form a gel nail sticker.

Further, the gel nail sticker forming step S300 may further include a cutting process (P320) of cutting the gel nail sticker into a nail or claw shape. This can be omitted if the gel nail sticker produced through the third binding process (P310) corresponds to a nail or a toenail shape.

Herein, the processes and steps of the method for manufacturing a gel nail sticker are not limited to those described above, and a gel nail sticker can be manufactured in any order as long as the gel nail sticker described above can be formed.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
