Description

Volume gel nail sticker {VOLUME GEL NAIL STICKER}

The present invention relates to a volume gel nail sticker.

Because the top layer of the existing gel nail sticker is flat, when it is attached to the nail, cut lines are cut at the edge, which may cause a lifting phenomenon due to hair jamming or interference with foreign substances.

An object of the present invention is to provide a gel nail sticker in which the uppermost layer is a curved volume layer.

In order to achieve the above object, a nail sticker according to an embodiment of the present invention includes an adhesive layer; a gel coating layer arranged on the adhesive layer; and a volume layer arranged on the gel coating layer. Here, the volume layer is a curved coating layer having a sense of volume.

The gel nail sticker of the present invention includes a curved volume layer, and as a result, there is no foreign body feeling, and gloss and durability can be maintained.

In this specification, terms such as "consisting of" or "comprising" should not be construed as necessarily including all of the various components or various steps described in the specification, some of which components or some steps are It should be construed that it may not include, or may further include additional components or steps. In addition, terms such as "...unit" and "module" described in the specification mean a unit that processes at least one function or operation, which may be implemented as hardware or software, or a combination of hardware and software. .

The present invention relates to a volume gel nail sticker, and by forming a volume layer on the upper layer, it is possible to maintain the same volume feeling as during the procedure and to prevent the floating phenomenon.

1 is a cross-sectional view illustrating a gel nail sticker according to an embodiment of the present invention, and FIG. 2 is a view showing the difference between the existing gel nail sticker and the volume gel nail sticker of the present invention. 3 is a view showing a table showing the component ratio of the volume layer according to an embodiment of the present invention, FIG. 4 is a view showing an experimental table of the volume layer, and FIG. 5 is a view showing the results of the experiment of FIG. It is the drawing shown.

Referring to FIG. 1 , the gel nail sticker of this embodiment may have a structure in which an adhesive layer, a urethane coating layer, a color layer, a gold/silver foil layer, a glitter layer, a gel coating layer, and a volume layer are sequentially formed.

The adhesive layer is a layer for adhesion to the nail.

The urethane coating layer is arranged on the adhesive layer, and may be formed of a gel UV coating agent of a medium-strength urethane component. The urethane coating layer may be formed on the adhesive layer by applying a liquid medium-strength urethane to the adhesive layer to a predetermined thickness and then UV curing. This urethane coating layer corresponds to the base layer of the color layer.

The color layer is arranged on the urethane coating layer, and is a layer for implementing the color of the gel nail sticker. Such a color layer may be formed by printing color ink to a predetermined thickness on the urethane coaching layer by offset printing or silk screen printing. Here, CMYK or the like may be used as the color ink, and C (blue), M (red), Y (yellow) and K (black) may be appropriately mixed or used alone.

According to an embodiment, the color layer may be formed by printing the color ink several times with a thin thickness.

The gold/silver foil layer may be arranged on the color layer through thinning.

The glitter layer is arranged on the gold/silver foil layer as a glitter layer, and may be unevenly formed.

The gel coating layer is arranged on the glitter layer, and may be formed by applying the gel coating solution to a thin thickness on the glitter layer and drying it several times.

The volume layer is arranged in a curved surface on the gel coating layer, and may be formed to have a volume structure.

While the top layer of the conventional gel nail sticker is flat, the top layer of the volume gel nail sticker of the present invention may be formed of a curved coating layer (volume layer).

As shown on the left side of FIG. 2 , when a conventional gel nail sticker is attached to a nail, an unnatural one-shaped end occurs due to cutting of the edge part, and as a result, it is usually caused by hair jamming or foreign matter interference. As a result, a lifting phenomenon may occur.

On the other hand, as shown on the right side of FIG. 2 , when the volume gel nail sticker of the present invention is attached to the nail, there is no foreign feeling of the sticker and the gloss and durability can be maintained with the same volume as the gel nail treatment at the nail shop. and the lifting phenomenon may not occur.

According to an embodiment, the volume layer contains an initiator, a monomer, an oligomer A, an oligomer B, and an additive as shown in the table of FIG. 3 . can do. Examples of these components are shown in the figure below.

The initiator is a photopolymerization initiator and is used to cure the coating film, and the monomer may provide fluidity during operation and reinforce adhesion.

The oligomer A performs a function of forming a film after curing, and the oligomer B prevents spreadability before curing after semi-gel type printing, and the additive may be an antifoaming agent. For example, the oligomer A may be a urethane acrylate, and the oligomer B may be a polyester acrylate.

According to one embodiment, the initiator has 5% to 10% by weight, the monomer has 15% to 22% by weight, the oligomer A has 45% to 52% by weight, and the oligomer B is 15% to 22% by weight, and the additive may have less than 5% by weight.

Experiments and experimental results of these volume layers are shown in FIGS. 4 and 5 . As shown in FIGS. 4 and 5 , when the critical range of each component is exceeded, it can be confirmed that at least one of volume formation, flexibility, undercoat adhesion, surface tack, and printability has a defect.

Specifically, in the case of 'A' in which oligomer A and oligomer B are out of weight ratio, volume formation is not properly performed and flexibility is lowered, and in case of 'B' in which the content of oligomer B is small, volume formation is not properly performed. In addition, 'C' and 'D' having a normal weight ratio have good properties, and in the case of 'E', 'F' and 'G', where monomer, oligomer A and oligomer B are out of weight ratio, surface tack and printability are bad

Looking at the manufacturing process, the volume gel nail sticker is transparent in the form of a thick film (1-1.5 mm) on the surface on which the color layer, the gold/silver foil layer, the glitter layer, the gel coating layer and the volume layer are printed on the urethane coating layer. It can be made by printing clear.

On the other hand, the components of the above-described embodiment can be easily grasped from a process point of view. That is, each component may be identified as a respective process. In addition, the process of the above-described embodiment can be easily understood from the point of view of the components of the apparatus.

The above-described embodiments of the present invention have been disclosed for the purpose of illustration, and various modifications, changes, and additions will be possible within the spirit and scope of the present invention by those skilled in the art having ordinary knowledge of the present invention, and such modifications, changes and additions should be regarded as belonging to the following claims.
