[0030] The manufacturing method of the gel nail seal according to the present invention can provide a gel nail seal having a coating layer formed on a soft curved surface.

[0031] 1 and 2 are cross-sectional views of a gel nail seal according to one embodiment of the present invention, FIG. 2 is a flowchart of a method for manufacturing a gel nail seal according to one embodiment of the present invention, and FIG. 4 is a perspective view showing the error range of a nail plate according to one embodiment of the present invention.

[0032] The manufacturing method of the gel nail seal according to Figures 1 to 4 includes step S100 of applying a primer to a base 110, step S200 of printing a user's nail image, step S300 of forming a first coating layer 130 on the printed base, step S400 of cutting the base 110 with the first coating layer 130 formed thereon to fit the shape of the user's nail, and step S500 of forming a plurality of coating layers on the cut base 110 with the first coating layer 130 formed thereon.

[0033] The manufacturing method of the gel nail seal first includes step S100 of applying a primer to the base 110. The primer is a liquid coating material that increases the adhesion of the coating object to fix it and prevents corrosion and water penetration. By applying the primer to the base 110, the surface tension can be increased by the primer. Preferably, the base 110 may include a polyurethane (PU)-based fabric bonded to the upper surface of a PET film, but is not limited thereto. Polyurethane is a material that is tough and highly elastic, has high tensile breaking strength, and has excellent abrasion resistance, aging resistance, oil resistance, etc.

[0034] When the primer is applied to the base 110, a step S200 is performed in which a nail image is output by a printing method to form a printing layer 120. The nail image can be determined to have a shape and size selected by the user. The nail image selected by the user based on the determined design is stored in the PC. Here, the nail design may be determined as a final design after an image designed by the user is stored and uploaded to the PC. In addition, a nail photo of the user taken by a mobile terminal such as a mobile phone is uploaded. This allows accurate matching and adhesion without error by comparing and analyzing the photo or video of the user's nail and the determined nail design by the PC. Next, a process of editing the stored nail image is performed. In one example, the editing of the final determined nail image is performed by a process of reflecting the nail size, shape, color, and curvature radius of the curved surface of the user and flattening it, and output by a printing method on the base 110 to which the primer is applied, to form the printing layer 120. The printing layer 120 is formed by applying or adding various materials for aesthetics such as various patterns, designs, mica, and fine particles of the gel nail seal 100. The printing method is not particularly limited, and various printing methods such as digital printing, silk screen printing, flexographic printing, and gravure printing can be applied. Of course, the printing layer 120 may be omitted as necessary. The printing layer 120 may further include a color layer (not shown). The color layer may be formed by applying offset printing or silk screen printing. The color layer is printed to have the shape of a fingernail or a toenail. The color ink of the color layer may be CMYK, where C is blue, M is red, Y is yellow, and K is black, and the color inks may be appropriately mixed or used alone in various ways.

[0035] After the printing step, the substrate is coated to form the first coating layer 130 (S300). The first coating layer 130 is coated with a coating resin, which is preferably, but not limited to, a UV resin and can be formed into a photo-cured layer. The coating resin can be hardened by irradiation with ultraviolet light and applied to the base 110 to form the first coating layer 130. The first coating layer 130 can include a material that dries by heat, a photoinitiator, and other additives. Preferably, the first coating layer 130 can be formed to a thickness of 0.12 to 0.17 mm, but is not limited to this.

[0036] After the first coating layer is formed, a cutting step S400 is performed to fit the user's nail. The cutting can be performed using a digital cutting machine according to the shape and size of the user's nail.

[0037] The first coating layer 130 is formed before cutting according to the shape and size of the user's nail, which makes cutting easier and makes it easier to form a coating lower end that matches the user's nail. Also, by cutting according to the size and shape of the user's nail before forming the second coating layer 140 and the third coating layer 150, a soft coating layer is formed due to cohesive force and release force.

[0038] After performing a cutting step S400 according to the shape and size of the user's nail, a step S500 is performed in which a plurality of coating layers are formed on the base 110 on which the first coating layer 130 cut to fit the user's nail is formed. The step of forming a plurality of coating layers includes a step of forming a second coating layer 140 on the first coating layer 130, and a step of forming a third coating layer 150 on the second coating layer 140.

[0039] The second coating layer 140 and the third coating layer 150 are formed by the step S500 of forming a plurality of coating layers on the base 110 on which the first coating layer 130 is formed and cut to fit the user's nail. The second coating layer 140 and the third coating layer 150 are coated with a coating resin, and the coating resin may be formed into a photo-curable layer, preferably including a UV resin, but is not limited thereto. The second coating layer 140 and the third coating layer 150 may be formed by including a UV resin and curing it by irradiation with ultraviolet light. The second coating layer 140 and the third coating layer 150 may include a material that dries by heat, a photoinitiator, and other additives. Preferably, each of the second coating layer 140 and the third coating layer 150 may be formed to a thickness of 0.12 to 0.17 mm, but is not limited thereto.

[0040] In the coating layer forming step S500, a nail plate 200 that is within the error range of the shape and size of the user's nail can be searched for based on a pre-stored database, and coating can be performed based on the nail plate 200 that is within the error range of the shape and size of the user's nail to form the second coating layer 140 and the third coating layer 150.

[0041] 4 is a perspective view showing the error range of the nail plate according to an embodiment of the present invention. According to FIG. 4, when the nail of the user is larger or smaller than a predetermined size, the corresponding nail plate 200 can be used, and if there is no nail plate 200 within the error range, a new nail plate 200 can be produced and stored in a database for manufacturing.

[0042] In addition, the second coating layer 140 and the third coating layer 150 are applied to an area smaller than the cut area of ​​the base 110 according to the size and shape of the user's nail. The application area is formed smaller than the area of ​​the cut base, and the coating is applied to a precise area due to the release force and the cohesive force of the coating resin, so that the coating solution does not flow outward and a soft layer can be formed.

[0043] The step of forming a plurality of coating layers S500 may further include a step of forming a fourth coating layer 160 on the third coating layer 150. The third coating layer 150 is coated with a coating resin, which is preferably formed into a photocurable layer including a UV resin, but is not limited thereto.

[0044] The first coating layer 130, the second coating layer 140, and the third coating layer 150 are formed with different degrees of hardening. The third coating layer 150 is formed in the portion exposed to the outside to prevent external damage to the gel nail seal in a solid hardened state. The first coating layer 130, the second coating layer 140, and the third coating layer 150 may contain a material that dries by heat, a photoinitiator, and other additives. Therefore, when hardened by external UV irradiation, the UV-hardening raw material allows the inside of the hardened outer coating to maintain flexibility.

[0045] The coating layer formed by applying the coating resin can be completely cured by irradiation with external ultraviolet light at a predetermined time interval. According to the present invention, the coating layer can be completely cured by irradiation within a wavelength range of about 250 to 410 nm. The coating layer can be cured at least two times by changing the wavelength of the ultraviolet light. For example, the coating layer is provided as a finished product of the gel nail seal 100 in a semi-cured state by primary irradiation within the wavelength range, and then the user can completely cure the coating layer by secondary irradiation within the wavelength range. Preferably, the coating layer is semi-cured by primary irradiation with a wavelength of about 250 to 320 nm, and then completely cured by irradiation with a wavelength range of 360 to 410 nm.

[0046] The coating layer formed according to the present invention is coated with a coating resin, and the coating resin gathers in the area cut according to the size and shape of the user's nail and the size due to the cohesive force of the coating resin and the release force of the base, forming the second coating layer 140 and the third coating layer 150. After cutting according to the size and shape of the user's nail, a coating layer with a soft curved surface is formed by the cohesive force and the release force. Before forming the second coating layer 140 and the third coating layer 150, cutting is performed according to the size and shape of the user's nail, and after cutting, coating is performed to form the second coating layer 140 and the third coating layer 150 to form a soft curved surface. The coating resin may preferably include a UV resin that is cured by UV, but is not limited thereto.

[0047] An adhesive auxiliary layer 10 may be formed between the first coating layer 130, the second coating layer 140, and the third coating layer 150. The adhesive auxiliary layer 10 is formed to improve adhesive performance by complete curing in the curing step of the coating layers.

[0048] FIG. 5 is a flowchart of a method for manufacturing a gel nail seal according to another embodiment of the present invention.

[0049] The manufacturing method of the gel nail seal according to FIG. 5 may include step S10 of applying a primer to a base 110, step S20 of printing a user's nail image, step S30 of cutting the base 110 with the printed layer 120 formed thereon to fit the shape of the user's nail, and step S40 of forming a plurality of coating layers on the cut base 110 with the printed layer 120 formed thereon.

[0050] The steps of applying a primer, forming a print layer, and cutting are the same as those in the embodiment of the present invention, and therefore a description thereof will be omitted.

[0051] The step of forming a plurality of coating layers may form a first coating layer, a second coating layer, and a third coating layer. The step S40 of forming a plurality of coating layers on the base 110 on which the printing layer 120 cut to fit the user's nail is formed forms the first coating layer 130, the second coating layer 140, and the third coating layer 150. The first coating layer 130, the second coating layer 140, and the third coating layer 150 are coated with a coating resin, and the coating resin may be formed into a photo-curable layer, preferably including a UV resin, but is not limited thereto. The first coating layer 130, the second coating layer 140, and the third coating layer 150 may be formed by including a UV resin and curing it by irradiation with ultraviolet light. The first coating layer 130, the second coating layer 140, and the third coating layer 150 may include a material that dries by heat, a photoinitiator, and other additives.

[0052] In the coating layer forming step S40, a nail plate 200 that is within the error range of the shape and size of the user's nail can be searched for based on a pre-stored database, and coating can be performed based on the nail plate 200 that is within the error range of the shape and size of the user's nail to form the first coating layer 130, the second coating layer 140 and the third coating layer 150.

[0053] In addition, the first coating layer 130, the second coating layer 140 and the third coating layer 150 are applied to an area smaller than the cut area of ​​the base 110 according to the size and shape of the user's nail. The application area is formed smaller than the area of ​​the cut base, and the coating is applied to a precise area due to the release force and the cohesive force of the coating resin, so that the coating solution does not flow outward and a soft layer can be formed.

[0054] The step of forming a plurality of coating layers S40 may further include a step of forming a fourth coating layer 160 on the third coating layer 150. The third coating layer 150 is coated with a coating resin, and the coating resin may be formed into a photocurable layer, preferably including a UV resin, but is not limited thereto.

[0055] The gel nail seal according to the manufacturing method of the present invention is manufactured by sequentially applying and stacking the printing layer 120, the first coating layer 130, the second coating layer 140, and the third coating layer 150 to manufacture the gel nail seal 100. In addition, before forming the second coating layer 140 and the third coating layer 150, the gel nail seal 100 is manufactured by cutting according to the size and shape of the user's nail, so that a coating layer with a soft curved surface can be formed.

[0056] The gel nail seal 100 according to an embodiment of the present invention may include a printing layer 120 formed by printing a pattern on a base 110 coated with a primer, a first coating layer 130 formed on the printing layer 120, a second coating layer 140 formed on the first coating layer 130, and a third coating layer 150 formed on the second coating layer 140, and the second coating layer 140 and the third coating layer 150 are formed by cutting according to the size and shape of a user's nail and then coating. After cutting according to the size and shape of a user's nail, the second coating layer 140 and the third coating layer 150 are formed, and after all the coating layers are coated, a coating surface having a softer curve than that of an existing gel nail seal cut to fit the user's nail is formed.
