Abstract

PROBLEM TO BE SOLVED: To form a thin and strong decoration surface, in a nail decoration method (nail art) using a sealing material (nail decoration member) and a photocurable gel agent.SOLUTION: After forming a base layer 12 by applying a photopolymerization type gel agent to the surface of a nail B and curing it, a nail decoration member (sealing material A) formed into a thin film shape with the same material as a base layer forming gel agent on a surface in an uncured state (uncured gel 12a) and turned to a desired color and shape is stuck with an uncured base layer surface as an adhesive layer and cured.

Description

  The present invention relates to a nail art decoration method called nail art and a decoration member used in the decoration method.

  Decorating nails with various pattern colors is called nail art and is generally performed widely. In particular, among various nail decoration means, the flat decoration means is obtained by thinly applying a gel-like member such as an ultraviolet curable resin (Patent Documents 1, 3, 4, 5, etc.) to the surface of the nail and curing it. A color pattern is formed on the surface with a brush or an air brush, or a color pattern is formed with a seal (Patent Documents 1 and 2) to which a thin sheet-like decorative member or adhesive is applied, and the surface is transparent. I try to protect it with a good top coat.

JP 2001-169823 A. Japanese Patent Application Laid-Open No. 2004-202768. JP 2009-56077 A. JP 2009-126833 A. JP 2011-167315 A

  Currently, the most commonly used means is to form a base layer with a gel-like member, apply a transfer seal (a sticker for sticking disclosed in Patent Document 2), and apply a top coat. For example, when an ultraviolet curable resin is used as the gel-like member, the surface of the gel member that comes into contact with air during the ultraviolet curing is not cured, and the adhesiveness with the seal is poor, so an operation to wipe off the non-cured portion is necessary.

  Further, since the sealing material has a double structure of the display layer and the adhesive layer, the sealing material has a thickness, and when it is pasted on the top or when it is stuck to the nail, it has a problem in durability.

  Therefore, the present invention proposes a novel sealing material (decorative member) and a decoration method excellent in workability and durability.

  The nail decoration member (sealing material) according to the present invention is a photopolymerization type gel agent for base layer formation used for nail decoration, and is formed into a thin film and a desired color and shape. It is what.

  Further, the nail decoration method according to the present invention is a method in which a photopolymerization type gel agent is applied to the surface of a nail or an artificial nail and cured to form a base layer. A nail decoration member made of the same material as a thin film and having a desired color and shape is bonded and cured using the surface of the uncured base layer as an adhesive layer.

  Thus, for example, a gel material that becomes a base layer is made of a material that is cured by photopolymerization reaction by irradiation with ultraviolet rays or visible light, and the nail decoration member (sealing material) is preliminarily coated with the gel agent. A thin film develops between transmissive films to form an air-blocking state, which is irradiated with light (ultraviolet rays / visible light) to be cured and formed into a thin film, and this thin film is formed with an appropriate color. The coloring process may be performed before the curing process or after the curing process. The colored thin film is cut into a desired shape such as a star shape, a heart shape, or a leaf shape, and produced as a predetermined sealing material.

  The nail decoration (nail art) is first subjected to surface treatment (cleaning, etc.) of the nail, and then the same gel agent used for the sealing material is applied and cured by a photopolymerization reaction. In the curing process, the surface layer is in contact with air (oxygen), and is not cured and is in an uncured state. The sealing material is placed on the uncured surface to form a desired pattern, and further subjected to a photocuring treatment, or after applying a gel agent, a photocuring treatment is performed. The uncured portion in between functions as an adhesive layer by the curing. In addition, the uncured portion is wiped off as a finish, and if necessary, a top coat (protective film layer) is applied. Therefore, the base layer and the pattern forming layer (sealing material) are the same kind of material and are integrated without being peeled off, so that the fastness is enhanced.

  The structure of the present invention employs the same gel material for the base layer and the same sealing material as described above, and uses the uncured surface portion of the base layer as the adhesive layer for the sealing material, requiring an adhesive. Since the sealing material that is not required can be made thin, there is no problem even if overlapping parts occur, it is not formed thick as a nail decoration, and it is the same material as the base layer. It is integrated with the layer, and its durability is also improved.

  Next, production of the present invention (member for nail decoration: seal member) will be described. The seal member A is made from the gel agent 1 used for nail decoration (nail art). Various products are commercially available for the gel agent 1, but a material that is cured by photopolymerization reaction upon irradiation with ultraviolet rays or visible light (for example, a main component is “methacrylic acid ester monomer, acrylic acid oligomer, photopolymerization initiator”). A “polyethylene acrylate oligomer” or the like is employed.

  The gel agent 1 is thinly developed between the light-transmitting films 2 to be in an air-blocking state, and is irradiated with light irradiation (ultraviolet light / visible light) 3 to be cured to form a thin film (several tens of 100 microns or less in thickness). Micron) 11. The thin film 11 is provided with an appropriate color, but the coloring process may be performed by mixing a colorant (pigment) in advance with the gel agent 1 itself, but since the film is thin, the color is thin. It is better to perform a separate coloring treatment.

  For example, as a coloring process, a water-soluble acrylic paint is colored with the air spray 4 after the thin film is cured or before the thin film is cured, or directly painted after the curing to perform pattern coloring.

  Further, after the thin film is cured, the thin film 11 is cut into a desired shape such as a star shape, a heart shape, a leaf shape or the like after the coloring treatment, and the sealing material A is produced.

  The method of the present invention is a nail decoration method (nail art) using the sealing material A. The basic work procedure is the same as before, and the nail B is first cleaned. In the cleaning operation, cuticle treatment is performed, then the surface is lightly siding (to ensure adhesion with the base layer 12), and finally dust is removed.

  The transparent or colored gel agent 1 is applied to the cleaned surface of the nail B so that the thickness is uniform. The gel agent 1 is applied and light irradiation 3 is performed, and the applied gel agent is cured to form the base layer 12. When the base layer 12 is formed, the surface side is in contact with air and becomes an uncured gel 12a.

  In the past, the uncured gel 12a was wiped off as it is, but the present invention is left as it is, and the sealing material A is applied with the surface uncured gel 12a as an adhesive layer to form a desired pattern.

  When the application of the sealing material A is completed, the light irradiation 3 may be performed as it is to cure the surface uncured gel 12a and function as an adhesive layer. However, the transparent or colored gel agent 1 is applied again to obtain the final light. It is better to cure by irradiation 3 to form the protective layer 13.

  In particular, without forming the protective layer 13, when the adhesive layer is cured, the uncured gel 12a is wiped off, and when a top coat (transparent protective film) as a separate member is applied and formed, the uncured gel 12a is wiped off. In order to prevent discoloration of the seal member A during work, the color forming surface is the back surface when the seal material A is applied.

  After the protective layer 13 is formed (final photocuring), the uncured gel 13a remains on the surface side. This is wiped off, and the surface is further polished to perform a finishing treatment.

  As described above, since the present invention is formed of the same material as the gel agent 1 as the sealing material A, the surface uncured gel 12a at the time of forming the base layer 12 is used as an adhesive for the sealing material A as it is. It can be formed thinner than conventional sealing materials that require different adhesives, and this also makes it possible to easily realize a layered decoration a (FIG. 3) of the sealing material, thereby increasing the overall strength. This also helps prevent cracking.

  In addition, the base layer 12, the sealing material A, and the protective layer 13 are all the same material, and are integrated by curing by photopolymerization, so that robustness can be secured, so that even when the nail decoration b is performed, the roll-up is performed. There is no risk of it occurring.

  In addition, although the said embodiment showed the example which decorates the nail | claw B directly, it can apply similarly to a nail chip | tip (artificial nail | claw). Moreover, the specific application (light irradiation time etc.) of hardening by light irradiation is suitably determined according to the gel agent to be used.
