BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

1 is an exploded cross-sectional view of an interior film according to a first embodiment of the present invention.

Referring to FIG. 1, the interior film according to the first embodiment of the present invention comprises a base film 110, a metal layer 120, and a pattern layer 130 from above.

The base film 110 is formed on the surface side of the interior film and is not particularly limited as long as it is a conventionally known plastic film excellent in workability such as cutting, bending and the like. For example, the base film 110 may be formed of a material selected from the group consisting of polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate, polymethylmethacrylate (PMMA), polyester polypropylene (PP), polyethylene, polyacrylate, and the like, and one or more selected two or more of them may be selected from the group consisting of polyester, polyvinyl chloride (PVC), polypropylene And may be formed as a single layer or a multilayer including a mixture.

The base film 110 is preferably made of a PET material having excellent uniformity and transparency. In this case, the hairline pattern effect of the pattern layer 120 can be further enhanced.

The base film 110 is preferably formed to have a thickness of about 10 탆 to 100 탆, and more preferably 20 탆 to 50 탆. When the thickness of the base film 110 is less than 10 mu m, the mechanical strength is not sufficient, and care must be taken in handling, which may lower productivity. On the other hand, when the thickness of the base film 110 is more than 100 mu m, the handleability and processability of the film may deteriorate, and physical properties such as adhesion may be deteriorated, which is also economical.

However, in the specification of the present invention, the surface side of the interior film is defined as a side exposed to the outside attached to a target such as a building, a home appliance, an electronic product, an automobile, and the like, and the opposite side is defined as an inside side.

The metal layer 120 may be interposed between the base film 110 and the pattern layer 130. The metal layer 120 may be a metal layer, a metal layer, or a metal layer. That is, the metal layer 120 is formed on the inner surface side base film 110 of the interior film.

The metal layer 120 is formed of aluminum (Al), stainless steel, copper (Cu), gold (Au), silver (Ag), nickel (Ni), chromium (Cr), cobalt And may include one kind or two or more kinds selected from them. However, it may be variously modified to at least two kinds of alloys or metal oxides selected therefrom according to the metal texture effect to be realized.

The metal layer 120 may be formed as a single layer or a multilayer using the above-described metal, and may be formed as a multilayer. When the metal layer 120 is formed in multiple layers, it is possible to exhibit a metallic appearance effect that can produce a more luxurious appearance than when formed as a single layer through the thickness and color control of each layer, and realize various color and high- It is possible.

The metal layer 120 may be formed to have a thickness of about 100 nm to 1000 nm for metal texture implementation, but is not limited thereto. The metal layer 120 may be manufactured with different characteristics depending on the intended use of the final product. If the thickness of the metal layer 120 is less than 100 nm, the color may darken and be different from the original metal color. On the other hand, when the thickness exceeds 1000 nm, the adhesion is decreased to detach the film or reduce the durability of the final product .

In addition, the metal layer 120 can enhance the image of the pattern of the pattern layer 130 and provide a feeling of a unique texture of the metal layer so that the pattern layer 130 can be seen in various colors depending on the viewing angle of the image of the pattern layer 130. [ do. This is because the wavelength of light reflected from the surface of the metal layer 120 through the pattern layer 130 changes according to the wavelength of the incident light.

The pattern layer 130 is formed on the metal layer 120 and includes a concavo-convex pattern of the hairline pattern to enable the diffusing effect of the metal layer 120 to be realized.

The pattern layer 130 may be formed of a relatively inexpensive plastic material instead of an expensive metal plate, and may be formed of a UV-curable resin composition, for example.

At this time, the ultraviolet curable resin composition may include an acrylic monomer, an oligomer thereof, and a photoinitiator, and may further include additives such as pigments to complement other physical properties.

Examples of the acrylic monomer include acrylates or urethane acrylates having an alkyl group having 1 to 12 carbon atoms, and specific examples include butyl acrylate, hexyl acrylate, n-octyl acrylate, isooctyl acrylate, 2- Ethylhexyl acrylate, isononyl acrylate or other (meth) acrylate monomers, but is not limited thereto.

In order to increase the surface hardness of the ultraviolet ray curable resin composition, the crosslinking of the cured resin increases, and the hardness becomes stronger. Therefore, the monomers constituting the ultraviolet ray curable resin composition must be used with a multifunctional group. However, as the number of functional groups increases, the dimensional stability, elongation and flexibility And cracks may occur during bending molding. Therefore, it is necessary to use an appropriate functional monomer.

As the photoinitiator, a radical initiator known in the art such as 2,2'-azobisisobutyronitrile (AIBN), benzoyl peroxide (BPO) and Irgacure 184 can be used, and a light stabilizer such as Tinuvin 400 can be used in combination .

The coating solution used for the production of the pattern layer 130 may be a resin solution having a solid content of 30% to 100%, and may be a solution in which a solvent is not added to form the same pattern as a pattern formed in a mold such as an embossing roll It is preferable to use a resin composition (solid content: 100%).

The ultraviolet curable resin composition is advantageous as it has no adherence to metals in order to improve releasing force when releasing a film from a mold such as an embossing roll, and the lower the surface tension is, the more advantageous it is. However, since the interior film of the present invention includes the metal layer 120 on the pattern layer 130, it is possible to maintain the adhesion of the interior film product and to maintain the mold releasing force in a range of possible levels in the mold desirable.

Particularly, in the present invention, the pattern layer 130 includes a hairline pattern in the longitudinal direction of the base film 110, thereby realizing the appearance of a metal texture equivalent to a film of a conventional metal material.

The thickness of the concave-convex pattern is preferably approximately 1 탆 to 10 탆, more preferably 1 탆 to 5 탆. When the thickness of the concavo-convex pattern is formed within the above-described range, it is possible to realize a texture equivalent to the appearance effect of a metal imparted with a normal hairline pattern, for example, stainless steel, .

It is preferable that the width of the hair line in the hair line pattern is approximately 1 탆 to 50 탆, but the thickness of the concavo-convex pattern and the width of the hair line can be variously modified according to the desired appearance effect. More specifically, when it is desired to improve the stereoscopic effect of the hairline pattern or to obtain an appearance of the hairline, it is possible to form the hairline pattern by adjusting the thickness of the concave-convex pattern.

The pattern layer 130 is preferably formed in consideration of the thickness of the hairline pattern to be formed, and is preferably formed to a thickness of approximately 1 to 50 탆.

The hair line pattern according to the present invention is formed by an ultraviolet ray imprinting method and has an advantage that the length of the hair line can be easily adjusted.

The inner film according to the first embodiment of the present invention may further include a surface protective layer 140 formed on the base film 110 to protect the surface of the film from the external environment. For example, the surface protective layer 140 may be formed of a material such as acrylic, acrylic urethane, epoxy, polyurethane, polyisocyanate, polyester, acrylate, ethylene- Polyvinyl alcohol-based resin and the like can be used. The surface protective layer 140 may further include a silica-based filler in order to improve strength and mechanical properties.
