Method of forming artificial nail and artificial nail forming tool set

Technical field

The present invention relates to an artificial nail forming method and an artificial nail forming tool set for easily forming an artificial nail having a desired shape without damaging one's own nail. Background art

Conventionally, as an artificial nail, there has been known a method in which a plastic plate is adhered to the nail with an adhesive, or an ultraviolet curable resin is applied on the plastic plate in a predetermined shape, and the resin is cured by irradiating ultraviolet rays. .

According to the above-mentioned conventional technology, there is a problem that not only is there a difficulty in finding a plastic plate suitable for each person, but also there is a possibility of generating a bad smell due to ultraviolet irradiation, damage to own nails and skin, and the like. Was.

Also, by directly adhering the artificial nail resin composition to the surface of the nail, there is a risk of damaging the nail itself. Particularly, if the artificial nail is adhered for a long period of time, the surface of the nail becomes rough, Or, there was a problem of causing cracks.

Furthermore, even though the materials for forming artificial nails are available, the pre-treatment and post-treatment were individually selected by beginners, making it difficult for beginners to select appropriate ones, which was cumbersome. Disclosure of the invention

The present invention has solved various problems caused by ultraviolet rays by employing a resin which is cured not by ultraviolet curing but by visible light, for example, light of a halogen lamp or light of a light emitting diode. In addition, by applying a base coat agent on the nail, it was possible to protect the nail and improve the adhesiveness of the artificial nail. Furthermore, by setting an artificial nail forming device as a set, even beginners can arbitrarily produce high-quality artificial nails. It was possible to shape.

That is, the invention of the method comprises applying a base coat agent on the nail, layering a photocurable resin composition on the base coat agent to form a bare nail, and irradiating visible light with the bare nail. This is a method for forming an artificial nail, characterized in that the artificial nail is cured, and then the cured bare nail is shaped and finish-polished.

In the above method, a base coating agent is applied on the nail, a photocurable resin composition is layered on the base coating agent to form a bare nail, and a surface coating agent is applied on the bare nail. Thereafter, the bare nail may be cured by irradiating it with visible light. In the above method, the base coat agent may be one containing ethyl acetate, toluene, butyl acetate, and nitrocellulose as main components. Further, the photocurable resin composition may be one obtained by adding a photopolymerization initiator to a raw material component comprising an ethylenically unsaturated compound and a thermoplastic resin.

As the ethylenically unsaturated compound, a molecule containing at least two (meth) acryloyl groups in the molecule, for example, ethylene glycol di (meth) acrylate, polyethylene glycol di (meth) acrylate is employed. be able to.

As the thermoplastic resin, a resin that maintains a solid state at normal temperature, for example, an acrylonitrile-styrene copolymer or an acrylonitrile-butadiene-styrene copolymer can be used.

As the photopolymerization initiator, a known photopolymerization initiator can be used. For example, benzoinbenzoin methyl ether can be used.

The above-mentioned ethylenically unsaturated compound and the above-mentioned thermoplastic resin are blended to form a raw material component of a photo-curable resin composition. The blending ratio is: ethylenically unsaturated compound 5 to 70% by weight, thermoplastic resin It is preferably in the range of 30 to 95% by weight.

Further, the mixing ratio of the photopolymerization initiator is preferably 0.01 to 10 parts by weight based on 100 parts by weight of the raw material component.

Next, another invention is directed to a light source for irradiating a photo-curable resin (for example, a visible light lamp such as a halogen lamp or a light-emitting diode), a protector for forming an artificial nail, a packaged photo-curable resin composition, and a package. An artificial base coating agent It is a nail forming tool set. In addition, an artificial nail forming tool set characterized by setting a packaged surface coating agent and a finishing tool in addition to the above.

In the above invention, the photocurable resin composition may be a material obtained by adding a photopolymerization initiator to a raw material component comprising an ethylenically unsaturated compound and a thermoplastic resin, provided that the composition is harmless to the human body. Although not specified, in terms of appropriate hardness, color tone, durability, and moldability, etc., a photocurable dental composition (Japanese Patent Publication No. Hei 4-4-2623, Japanese Patent Publication No. Hei 5-3) 9 398) is suitable.

That is, since it can be used for dentistry, it has no toxicity and is easily adaptable to the human body, and has good hardness, durability, color tone and moldability.

The components of the ethylenically unsaturated compound, the thermoplastic resin, and the photopolymerization initiator in the photocurable resin composition, and the mixing ratio thereof can be the same as in the method of the invention.

The artificial nail forming protector plays a role of protecting a finger and forming a nail, and is configured to be fitted on a finger.

The above-mentioned base coating agent was used for the primary purpose of protecting self-nail and improving adhesiveness with an artificial nail mainly using ethyl acetate, toluene, butyl acetate and nitrocellulose as main agents. Although it also functions to clean its own nails and maintain its smoothness, components that can achieve this purpose are appropriately mixed in.

The surface coating agent is used for the purpose of smoothing the surface of the artificial nail and coloring as necessary. For example, any color can be selected without being caught by the color tone of the photocurable resin composition. As the surface coating agent, for example, a synthetic paste can be used.

The artificial nail forming tool set of the present invention can add a conventional nail setting set (nail clipper, nail polisher, coating agent, etc.), and can also add nail oil. It is more convenient to store a light source other than the light source for irradiating the photocurable resin in a bag or other container. According to the present invention, since the base coating agent is applied when forming the artificial nail, there is an effect of protecting the own nail and improving the adhesiveness with the artificial nail.

In addition, since this is cured by visible light using a visible light curable resin, there is no risk of injury due to ultraviolet irradiation. Apply a surface coating agent or nail oil This has the effect of further improving the finish of the artificial nail.

Next, by setting the equipment to be used, the artificial nail forming operation is facilitated, and since there is a necessary item when necessary, there is an effect that the artificial nail can be molded in a simple manner. BRIEF DESCRIPTION OF THE FIGURES
