It should also be understood that the position or arrangement of individual components within each disclosed embodiment may be varied without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is to be limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly explained. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

As shown in FIG. 1, the integrated 3D film case according to one embodiment of the present invention includes a 3D film layer 100, a digital print layer 200 formed under the 3D film layer, A silk print layer 300 to be formed, a binder print layer 400 formed under the silk print layer, and a case (not shown) formed under the binder print layer.

The integrated 3D film case according to another embodiment of the present invention includes a 3D film layer, a digital print layer formed under the 3D film layer, a silk print layer formed under the digital print layer, An optical film layer formed under the OCA layer, a binder print layer formed under the optical film layer, and a case formed under the binder print layer.

At this time, among the constituent components of the integrated 3D film case described above, the silk print layer is a print layer according to the silk printing method, and the color is clear and it is possible to realize a slight emboss feeling although it is flat. It is also possible to print on the surface of various materials and can be mainly used to give a whitening effect.

In addition, the digital print layer included together is a print layer according to a digital printing method using UV. It can realize a clear and bright color while utilizing the texture of the material. Especially, since the ink hardening speed is fast, The manufacturing time can be shortened. This can be used mainly when printing characters, logos, etc.

The 3D adhesive film according to another embodiment of the present invention may include at least one of a non-slip coating layer and an antibacterial coating layer as necessary.

The 3D film layer 100 includes a lens layer 110, a base layer 120 formed below the lens layer, and a pattern layer 130 formed under the base layer, as shown in FIG. 3 .

At this time, the base layer of the 3D film layer may be formed of at least one selected from the group consisting of PET (polyethylene terephthalate), TPU (thermoplastic polyurethane), PC (poly carbonate), PVC (poly vinylchloride) (Polypropylene, polypropylene), and the like, preferably a PC film.

On the other hand, when the TPU is contained in the base layer, it can be manufactured as a case for a curved product due to the flexible properties of the TPU.

The composition of the 3D film layer may also contain additives such as surface lubricants, leveling agents, antioxidants, light stabilizers, corrosion inhibitors, polymerization inhibitors, organic fillers, inorganic fillers, metal powders, At least one additive selected from the group consisting of dyes, pigments, ultraviolet screening agents, processing oils, and tackifiers may be suitably added depending on the use or purpose of the user.

The above-mentioned optical film layer may include at least one of urethane excellent in optical characteristics, particularly TPU (thermoplastic polyurethane) or PC (polycarbonate), and preferably includes PC.

An optical film (Light Guide Film) forms a pattern by performing dot-printing printing on a scattering pattern, a refraction, and a reflection pattern to scatter and reflect light on the above-mentioned film. The light rays are scattered by these grooves, Light scattering is easily reached even to a remote place, and a similar amount of light is emitted throughout the surface of the optical film.

Optical films can be roughly divided into three types according to their working methods: a molded optical film, a light scattering optical film, and a hollow optical film. Among them, the molded optical film is an optical film applied in the present invention, and includes both a method of processing a fine concave-convex pattern on the optical film itself and a method of printing a scattering body on the back side of the film. In such a printing optical film, it is necessary to print or transfer the scattering pattern, the refraction and the reflection pattern in order to scatter and reflect light.

And, the light scattering optical film distributes the light scattering polymer in the optical film, and an angle correcting prism that corrects the light traveling direction in the front direction is required. In addition, the hollow optical film has a structure in which the light from the light source is scattered in the space by emptying the center of the optical film, and the light is output through the diffusion sheet.

In the present invention, the above-described molded optical film is applied. As a method of forming the pattern at this time, a method of embossing patterns using a printing method, a method of embossing patterns by pressing, imprinting, You can apply any of the methods of giving.

As each material and pattern formation method has various fields and disadvantages, it can be selectively applied according to need, and its characteristics are as follows.

First, in the case of PC, it is possible to form an engraved pattern through high-temperature squeezing, which requires a cost of mold development and warping due to pattern transfer. However, it is difficult to achieve high mass productivity, There is an advantage of mass production quality stability.

Second, when a printing method is applied to form a positive pattern of a PC, it is relatively difficult to adjust the uniformity, and since the life of the printing plate is short, continuous management and replacement are required. However, It is possible to achieve a low development cost and quick development response, and it is possible to implement various color patterns.

In the case of forming an engraved pattern by imprinting of urethane, it is possible to process fine patterns and secure high uniformity. However, since the development period is longer than that of the other types, the development cost is relatively high, and the process becomes longer Therefore, there is a problem that the unit price is higher than other types.

Finally, when forming an embossed pattern using a urethane printing method, it has the same drawbacks and disadvantages as a PC. It shows high mass productivity, can realize various color patterns, can be developed at a low development cost, There is a problem in that uniform adjustment is relatively difficult and the life of the printing plate is short so that maintenance and replacement are required continuously.

In addition, the case may include at least one selected from silicon, PC, or plastic.

OCA (Optical Clear Adhesive) means an optical adhesive, which is excellent in optical characteristics, and is a glue that when a UV light is applied to an adhesive through a UV device, a photoinitiator in the adhesive starts to react and hardens in a few seconds . Because it can be easily and easily applied to various materials and can be firmly applied, it is easy to apply at the production site and it is hardened quickly without any stagnation of work. Therefore, the production line can be easily configured when the production line is applied.

The total thickness of the above-described integrated 3D case may be 0.5 to 10 mm, and when the thickness is less than 0.5 mm, it may be too thin to act as a protective film or to insert or write a desired image. If it is more than 10 mm, it may be too thick to give a soft feeling and a stable grip when mounted on a mobile device.

Further, the thickness of the 3D film layer may be 0.01 to 1 mm, and the digital print layer and the silk print layer may be independently 0.005 to 0.5 mm, and in the case of the case, 0.3 to 8 mm.

The adhesive force of OCA may range from 1000 to 3000 gf / 25 mm. If it is below the numerical range, the adhesive strength is weak and the adhesive can not be attached to the silk print layer and can be desorbed.

In the case of the integrated 3D film case including the optical film layer described above, the light is scattered and refracted on a film such as a PC material having excellent optical characteristics as described above, by using scattering and refraction through the optical film. When the light is irradiated from the light source, the portion having no pattern is totally reflected, and the portion having no pattern is irregularly reflected to obtain the desired light efficiency.

In addition, when a character, a telephone, or an alarm is applied to a device such as a smart phone, if a case according to an embodiment of the present invention is installed after turning on a rear flash, Due to the optical principle, it is possible to give a lighting effect with a desired pattern or the like to the entire case, so that the user can be informed of the telephone more quickly.

On the other hand, there may be cases where a pattern is not formed. In this case, the entire printed image on the silk print layer and the digital print layer can be given a lighting effect. In this case, And may be applied to both image and pattern formation.

The integrated 3D film case according to an embodiment of the present invention can coat a non-slip agent for improving non-slip performance on the top of the film so as to have a predetermined thickness, and the non-slip agent for forming the non- , A synthetic resin agent that maintains a constant viscosity on the surface during curing is preferably used. Specifically, a mixture of a resin and an ethylene-vinyl acetate copolymer (EVA) or a chemical binder having a viscosity of 50 to 70 cps As the chemical binder, a urethane binder or an acrylic binder may preferably be used.

At this time, when the viscosity of the chemical binder is less than the minimum value or the maximum value, the non-slip property is difficult to obtain due to the difference in viscosity of the binder, and in particular when the maximum value is exceeded, There is a problem that peeling may occur during use.

When the resin is mixed with the EVA resin, it may be composed of 45-60% by weight of resin as a base, 10-20% by weight of EVA, 1-3% by weight of stabilizer, and 25-35% by weight of plasticizer, As well as curling and reverse culling of the 3D film layer attached to the case.

When the above-mentioned non-slip coating layer is included, when the attached product is used by attaching the integrated 3D film case, the product does not slip smoothly in the hand, so that it is possible to prevent damages such as appearance damage or breakage of the product from external stimuli .

In addition, the integrated 3D film case according to another embodiment of the present invention may further include an antimicrobial coating layer. As the component of the coating layer, a polymer resin having high transparency, specifically, PET, TPU, PC, PVC or PP An antimicrobial material at a nanosize level may be added to the base resin, which may include but not be limited to one or more, and applied to the top of the 3D film layer.

In this case, the antimicrobial substance may include any substance that can be generally used as an antimicrobial substance, but specific examples thereof include, but are not limited to, ilite, zeolite, bentonite, silver nano, tourmaline, gelite or pozzolan .

If the transparency is lost by the addition of the antimicrobial substance, the essential effect of the present invention can not be exhibited. Therefore, the diameter of the antimicrobial substance may be in the range of 0.1 to 10 nm as spherical particles. The content of the antimicrobial substance may be 0.5 to 10 wt. %. ≪ / RTI >

Most of the above-mentioned antimicrobial substances are natural raw materials extracted from volcanic ash and loess, and they not only have antimicrobial effect but also excellent anion emission and electromagnetic wave shielding effect.

The anion released in this way increases the ionization rate of minerals such as calcium, sodium and potassium in the blood, purifies the blood through the progress of alkalization, and generates substances called endorphin and enkefirin, so that the ionization of calcium and sodium In addition to blood purification, fatigue recovery, and recovery of physical strength due to an increase in the rate, the cells in the part where strong pain is present are activated healthily, and the pain is relieved, and the blood is purified by electrical material exchange in the cell membrane. By increasing the amount of immunoglobulin, which increases the resistance to infectious symptoms, the use of anion therapy has a fast healing effect.

In addition, the anion is an air purification function. Various organic substances such as tobacco smoke, sulfur dioxide, nitrogen oxide, carbon monoxide and the like present in air form cations. Anions remove cations by precipitating these cations, To keep it clean and fresh.
