In general, when the user wants to improve the shape of the nails, he applies nail polish to perform nail art with the desired pattern. However, in the case of nail art applying nail polish to the fingernails, it was inconvenient that the operation was time consuming and troublesome, and that it took time for the applied solution to dry. In addition, when the user performs nail art directly on his or her fingernail, there is a problem that the shape of the nail art applied to each hand is not uniform depending on whether the user is left-handed or right-handed.

In order to solve these problems, the nail shop was professionally requested such as nail shop to improve the shape of the nails. However, when French nail art is performed by professionals, the cost burden has increased because of the need to pay for each time. Therefore, the market of nail stickers which can easily do nail art is becoming bigger for non-experts.

On the other hand, the nail sticker according to the prior art has the same effect as that of attaching gems by forming a three-dimensional decorative part on the base layer as disclosed in the patent documents of the following prior art documents.

As shown in Fig. 6, in addition to the stereoscopic decorating portion described above, various types of aesthetics can be emphasized by adding the light-reflective particles 2 to the base layer 1. Fig. In order to protect such light-reflective particles 2, a top coat 3 may be formed on the light-reflective particles 2. However, when the top coating 3 is formed on the light reflecting particles 2, irregularities are formed in the top coating 3 due to the volume and irregular size of the light reflecting particles 2 themselves, There is a problem that the glare effect of the light reflective particles 2 sharply drops.

BRIEF DESCRIPTION OF THE DRAWINGS The objectives, specific advantages and novel features of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements are assigned the same number as much as possible even if they are displayed on different drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1A and 1B are sectional views of a nail sticker using back printing according to an embodiment of the present invention.

1A and 1B, the nail sticker 100 using the back print according to the present embodiment includes a substrate 110 formed of polyurethane and light reflective particles 125, The adhesive layer 130 formed on the print layer 120 and the release layer 140 formed on the adhesive layer 130. The release layer 140 is formed on the adhesive layer 130,

The nail sticker 100 using the back printing according to the present embodiment directly prints the printed layer 120 including the light reflective particles 125 on the substrate 110 and finally prints the printed substrate 120 on the flat substrate 110, Is disposed at the outermost periphery. Accordingly, there is an advantage that a deep and shiny feeling of the light reflective particles 125 and a panning effect can be sufficiently realized.

The substrate 110 provides an area for printing the print layer 120 during the manufacturing process and protects the print layer 120 when the print layer 120 is actually attached to the nail. Here, the substrate 110 is formed of polyurethane. These polyurethanes have characteristics that are superior in printability to other materials such as PVC. Therefore, the printed layer 120 can be effectively printed on the substrate 110 formed of polyurethane. In addition, the surface of the substrate 110 on which the print layer 120 is printed is subjected to a surface treatment 115 such as an acrylic primer, a urethane primer, a plasma treatment, a corona treatment, etc. to improve the printability of the substrate 110, The printing layer 120 including the reflective particles 125 can be printed more effectively. Specifically, the acrylic primer and the urethane primer not only can increase the adhesive strength between the substrate 110 and the print layer 120, but also can enhance the adhesive strength. In addition, the plasma treatment or the corona treatment can increase the surface tension of the substrate 110. The surface tension of the substrate 110 to be adhered is greater than the surface tension of the printable layer 120 to be adhered and the wettability is improved so that the printable layer 120 can be effectively adhered to the substrate 110 have.

The print layer 120 substantially acts as a sense of aesthetics in the nail sticker 100. Here, the print layer 120 may be printed directly on the substrate 110. [ At this time, the print layer 120 may be printed on the substrate 110 using a roll coater, a bar coater, or a screen printing. In addition, the print layer 120 includes light reflective particles 125 that reflect light. At this time, the print layer 120 may be formed by mixing light reflective particles 125 with any one of acrylic resin, urethane resin, and combinations thereof, and the light reflective particles 125 may be formed by mixing the acrylic resin, , And combinations thereof, by screen printing, scattering, or spraying. Here, the light reflective particles 125 include a glitter, a bling, a spangle, a confetti, or a pearl, and have a certain volume. If the printing layer 120 including the light reflecting particles is printed on the substrate 110 through the front printing instead of the back printing, the light reflecting particles 125 may have a uniform volume, The glare effect of the lens may be deteriorated. More specifically, when the printing layer 120 is printed on the substrate 110 through the front printing and the top coating is formed on the outermost layer to protect the printing layer 120, Unevenness occurs due to the volume or irregular size. Accordingly, there is a problem that the glare effect of the light-reflective particles 125 is rapidly lowered due to diffuse reflection. However, the nail sticker 100 using the backside printing according to the present embodiment prints the printed layer 120 including the light reflective particles 125 on the substrate 110 through back printing, Is disposed at the outermost periphery. As a result, since the flat substrate 110 is disposed at the outermost position, regular reflection rather than diffused reflection occurs (see the arrow in FIG. 1A), and the deep reflective and shiny feeling of the light reflective particles 125, The effect can be realized as it is.

The adhesive layer 130 serves to adhere the nail sticker 100 to the nail and is formed on the print layer 120. Here, the adhesive layer 130 is not particularly limited, but may be formed of PSA (Pressure Sensitive Adhesive). This PSA is a pressure-sensitive adhesive material that is tacky when pressure is applied to the nail.

The release layer 140 protects the adhesive layer 130 until the nail sticker 100 is adhered to the nail and is formed on the adhesive layer 130. For example, the release layer 140 may include a pressure-sensitive adhesive layer 130 and a pressure-sensitive adhesive layer 130. The pressure-sensitive adhesive layer 130 may be formed of any material, (Polyethylene terephthalate), polypropylene (PP), or a combination thereof, on the opposite side of the contacting surface. As described above, the release layer 140 is subjected to a matt process to provide a slip property. Therefore, during the manufacturing process, the release layer 140 can effectively pass the automatic printing machine or the like, and the release layers 140 between the adjacent products can be prevented from sticking to each other.

Also, as shown in FIG. 1B, a three-dimensional decorative part 160 may protrude from the opposite side of one side of the substrate 110 on which the printing layer 120 is printed. Here, the three-dimensional decoration unit 160 can be formed using limestone or a gem-shaped transparent paint. By forming such a stereoscopic ornamental portion 160, it is possible to realize a sense of beauty like the real jewelry attached.

2A and 2B are perspective views illustrating a process of using a nail sticker using a back print according to an embodiment of the present invention.

2A and 2B, the nail sticker 100 using the back print according to the present embodiment can be manufactured by attaching the adhesive layer 130 to the nails after the release layer 140 is removed (See FIG. 2B). In this case, the adhesive layer 130, the print layer 120, and the substrate 110 are arranged in this order from the nail. That is, a flat substrate 110 is disposed on the upper side of the printing layer 120 including the light reflective particles 125. As described above, since the flat substrate 110 is disposed on the upper side of the print layer 120, irregular reflection or the like does not occur, and accordingly, the light reflective particles 125 have a deep and shiny feeling, The effect can be realized as it is.

3 is a cross-sectional view of a nail sticker using back printing according to another embodiment of the present invention.

As shown in FIG. 3, a binder layer 150 may be further formed between the adhesive layer 130 and the printing layer 120. Here, the binder layer 150 serves to prevent the irregularities from being generated in the adhesive layer 130 by the light reflective particles 125 included in the print layer 120. Specifically, when the adhesive layer 130 is directly formed on the print layer 120 including the light-reflective particles 125, the light-reflective particles 125 themselves are uniformly distributed in the adhesive layer 130 Unevenness may occur. The irregularities of the adhesive layer 130 not only deteriorates adherence of the nail sticker 100 to the nails but also deteriorates the flatness of the substrate 110 while bending the nail sticker 100 as a whole, There is a fear that the feeling of shiny and the effect of stickiness may be deteriorated. However, when the binder layer 150 is added between the adhesive layer 130 and the print layer 120, since the binder layer 150 absorbs the self-volume or irregular size of the light reflective particles 125, It is possible to prevent the flatness of the optical fiber 110 from deteriorating.

4 is a cross-sectional view illustrating a method of manufacturing a nail sticker using back printing according to an embodiment of the present invention in the order of steps.

As shown in FIG. 4, the method of manufacturing the nail sticker 100 using the back print according to the present embodiment includes the steps of (A) forming the polyurethane resin on the substrate 110, Printing the print layer 120, (B) forming an adhesive layer 130 on the print layer 120, and (C) forming a release layer 140 on the adhesive layer 130 do.

First, as shown in FIG. 4A, the substrate 110 is prepared. Here, the substrate 110 has excellent printing properties and is formed of polyurethane. In order to further enhance the printability of the substrate 110, a surface treatment 115 including a plasma treatment and a corona treatment may be performed on one surface of the substrate 110 on which the print layer 120 is to be printed.

Next, as shown in FIG. 4B, printing the print layer 120 on the substrate 110 is performed. Here, the print layer 120 may be printed using a roll coater, a bar coater, or a screen printing. The printing layer 120 may be formed of an acrylic resin, a urethane resin, or a combination thereof, and the light reflecting particles 125 may be mixed with the printing layer 120. At this time, the light reflective particles 125 may be mixed with any one of acrylic resin, urethane resin, and combinations thereof by screen printing, scattering, or spraying. On the other hand, the light reflective particles 125 have a constant volume, including glitter, bling, spangle, confetti, or pearl.

In this step, the printed layer 120 is printed on the flat substrate 110 by back printing, and finally the substrate 110 is disposed at the outermost position (see FIG. 4E), so that the light reflecting particles 125 does not affect the flatness of the outermost member (substrate 110). Therefore, the glare effect of the light-reflective particles 125 can be realized without the occurrence of diffuse reflection, as described above.

Next, as shown in FIG. 4C, the adhesive layer 130 is formed on the print layer 120. Here, the adhesive layer 130 is finally attached to the nail and may be formed of, for example, PSA.

Next, as shown in FIG. 4D, a release layer 140 is formed on the adhesive layer 130. The releasing layer 140 protects the adhesive layer 130. For example, the releasing layer 140 may be made of polyethylene terephthalate (PET), which is matt-treated on the opposite side of the adhesive layer 130, , Polypropylene (PP), and combinations thereof.

Next, as shown in FIG. 4E, a step of forming a three-dimensional decorative part 160 on the exposed surface of the substrate 110 is performed. Here, the three-dimensional decoration unit 160 can be formed using limestone or a gem-shaped transparent paint. It goes without saying that this step may be omitted as an optional step.

5 is a cross-sectional view illustrating a method of manufacturing a nail sticker using back printing according to another embodiment of the present invention.

The method of manufacturing the nail sticker 100 using the backside printing shown in FIG. 5 is different from the method of manufacturing the nail sticker 100 using the backside printing shown in FIG. 4 in that the printing layer 120 is formed on the substrate 110 (See Figs. 5A to 5B).

5C, a step of forming a binder layer 150 on the print layer 120 is added between the step of forming the print layer 120 and the step of forming the adhesive layer 130 . Here, the binder layer 150 may be formed of any one of acrylic, urethane, silicone, epoxy, and combinations thereof. In addition, the binder layer 150 absorbs the self-volume or irregular size of the light-reflective particles 125 included in the print layer 120. That is, the binder layer 150 serves to level the print layer 120. 5D, unevenness does not occur in the adhesive layer 130 even if the adhesive layer 130 is formed on the binder layer 150, so that the nail sticker 100 can be prevented from being bended as a whole have. On the other hand, after the adhesive layer 130 is formed on the binder layer 150, the release layer 140 can be formed on the adhesive layer 130 as shown in Fig. 5E, Likewise, the three-dimensional decorative portion 160 can be formed on the exposed surface of the substrate 110.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
