DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the structure of a panel including a backing sheet according to an embodiment of the present invention will be described in detail below with reference to Figs. 1 and 2. Fig.

FIG. 1 is a cross-sectional view schematically showing a panel including a backing sheet according to an embodiment of the present invention, and FIG. 2 is a sectional view schematically showing a sectional configuration of the backing sheet of FIG.

Referring to FIGS. 1 and 2, a panel 100 including a backing sheet according to an embodiment of the present invention includes a transparent plate 110 through which light is transmitted, and a backlit sheet 110 attached to one surface of the plate 110 120).

That is, since the panel 100 including the backing sheet according to the present invention can be manufactured by attaching the backing sheet 120 to one side of the plate 110, A method of painting various colors on an etched and patterned surface, and a method of positioning a decorative film between two plates (usually a glass plate) and then providing a process that is much superior to a method of pressing and pressing can be simplified have.

The transparent plate 110 through which light is transmitted can be implemented as a glass type whose main component is SiO ₂ and can be implemented in a plate form so as to have smoothness and excellent light transmittance.

In addition, a frame (not shown) can be attached to the edge of the transparent plate 110 through which light is transmitted, in order to mount the transparent plate 110 through which light is transmitted.

In addition, the backing sheet 120 may be attached to one surface of the transparent plate 110 through which light is transmitted. In addition, the backing sheet 120 may be entirely transparent and may include a partially printed design.

In addition, the backing sheet 120 may be provided in the form of a roll, and it may be attached to one side of a plate 110 of a transparent material through which a desired length is wound and cut and light is transmitted.

In addition, the backing sheet 120 may be attached to one side of the transparent plate 110 through which light is transmitted. Accordingly, it is possible to prevent partial unevenness that may occur when the decorative portion is attached to the transparent plate 110 through which light is transmitted separately.

In addition, since the transparent plate 110 is attached to the entire surface of the transparent plate 110 through which the light is transmitted, the transparent plate 110 through which the light is transmitted can be made of ordinary glass other than acryl-based or tempered glass .

The backing sheet 120 includes a coating layer 121, a base film 125, a metal layer 123 formed between the coating layer 121 and the base film 125 and formed on one surface of the base film 125, A print layer 127 formed on the other side of the print layer 125 and an adhesive layer 129 formed on the print layer 127.

The backing sheet 120 may further include a release layer (not shown) on the adhesive layer 129 to protect the adhesive layer 129 before it is attached to one side of the plate 110.

Further, the base film 125 may be a transparent plastic film having flexibility. Examples of the transparent plastic film include transparent plastic films such as triacetylcellulose (TAC) film, polyethylene terephthalate (PET) film, diacetylene cellulose film, acetate butylate cellulose film, polyethersulfone film, polyacrylic resin film, Ester film, polycarbonate film, polysulfone film, polymethylpentene film, polyether ketone film, (meth) acrylonitrile film and the like can be applied.

For example, the base film 125 may be formed of polyethylene terephthalate (PET) having excellent mechanical strength, chemical resistance, solvent resistance, and light transmittance.

Further, the base film 125 may be formed to a thickness of 50 탆 to 150 탆. When the thickness of the film of the base film 125 is smaller than 50 탆, it may be difficult to form the coating layer 121, the metal layer 123, the printing layer 125, or the like on the base film 125 by a coating method or the like .

On the other hand, when the thickness of the base film 125 is larger than 150 탆, it may be difficult to maintain the bonded state when the adhesive film 129 is adhered to one side of the plate 110.

In addition, the print layer 127 absorbs the ink ejected from the digital printer to form an image, and can improve the drying speed, color expressive power, and image durability of the image.

In addition, the print layer 127 may be patterned in an ink jet manner through latex ink discharged from a digital printer.

In addition, the print layer 127 may be made of a resin selected from a homopolymer or copolymer such as acrylic, polyurethane, polyester, PVC, ethylene vinyl acetate (EVA), polyvinyl alcohol, and the like.

In addition, the print layer 127 may further include inorganic particles such as silica particles or alumina particles to have extinction properties, and may further include a UV stabilizer.

The printed layer 127 may be formed by dissolving or dispersing the above-mentioned resin and additives such as inorganic particles, ultraviolet stabilizer, dispersant, defoamer, wetting agent and leveling agent in water, organic solvent or mixed solvent thereof The coating liquid may be formed on the base film 125 using a coating method such as gravure, microgravure, comma, or slot.

On the other hand, in order to form the printing layer 127 with a uniform thickness, the solid content in the coating liquid may be contained in an amount of 15 to 30% by weight, preferably 20 to 25% by weight.

Further, the printing layer 127 may be formed to a thickness of 10 mu m to 50 mu m. When the thickness of the print layer 127 is less than 10 mu m, it may be difficult to form an image on the print layer 127. When the thickness of the print layer 127 is more than 50 mu m, The color of the image printed on the printing layer 127 may be distorted as the color of the printing material 127 is changed.

The image is printed on the printing layer 127 by an inkjet method using a digital printer using ink such as an aqueous dye ink, a water pigment ink, a strong solvent pigment ink, a weak solvent pigment ink, a mild ink, an eco ink, and an oil ink can do.

Further, the inks can be used together with four inks of CMYK (cyan-magenta-yellow-black) and white inks. In other words, since white ink is used in combination with cyan, magenta, yellow and black inks, transparent white sheet 120 can be expressed in white, and additional color representations that can not be realized with only cyan, magenta, It can be possible.

 In addition, since the image is printed by the digital printer, the image desired by the consumer can be printed delicately and clearly. In addition, the inkjet type digital printing has no environmental problems due to an organic solvent used in gravure printing, silk screen printing, etc., and can freely select desired colors by freely selecting colors.

The adhesive layer 129 protects the printed image on the printed layer 127 and allows the backlit sheet 120 to adhere to the transparent plate 110 through which light is transmitted, Scattering of the material plate 110 can be prevented.

Further, the adhesive layer 129 may be formed of a silicon-based light or a thermosetting resin having both an elastic force and an adhesive property. For example, the adhesive layer 129 may be formed of a homopolymer or copolymer of a vinyl acetate type, an acrylic type, a polyurethane type, a polyester type, a polyamide type, or an epoxy type.

The adhesive layer 126 is a silicone resin containing a siloxane crosslinking reaction and may be a silicone resin such as polymethyltrifluoropropyl siloxane or polymethylvinyl siloxane As shown in FIG.

The adhesive layer 129 may include 1 to 10% by weight of an ultraviolet stabilizer. The adhesive layer 129 may be formed on the printed layer 127 on which an image is printed using a coating method such as gravure, microgravure, Mu] m to 50 [mu] m.

Further, by including the ultraviolet stabilizer in the adhesive layer 129, it is possible to prevent the phenomenon that the image is discolored by ultraviolet rays.

When the thickness of the adhesive layer 129 is less than 10 탆, the adhesive layer 129 hardly has a sufficient adhesive strength. On the other hand, when the adhesive layer 129 is formed thicker than 50 탆, ) Can be expressed. Therefore, the adhesive layer 129 is preferably formed to a thickness of 10 to 50 mu m.

On the other hand, before the adhesive layer 129 is adhered on one surface of the transparent plate 110 through which light is transmitted, a release mold 129 for protecting the adhesive layer 129 from foreign substances, scratches, A layer (not shown) may be attached.

Here, the releasing layer may include a polymethylpentene film, a polyethylene terephthalate (PET) film, a Teflon film, a polypropylene film, and the adhesive layer 129 may be formed on one surface of a transparent plate 110 through which light is transmitted As shown in FIG.

The coating layer 121 formed on the base film 125 or the metal layer 123 may be disposed at the outermost portion of the backing sheet 120 to improve impact resistance and scratch resistance. For example, the coating layer 121 may be formed on the other surface of the base film 125 or the metal layer 123 by a gravure coating method.

The coating layer 121 may include at least one selected from acrylic, urethane, epoxy, and siloxane polymer materials. The coating layer 121 may also include an ultraviolet curing resin such as an oligomer.

In addition, the coating layer 121 may include a silica-based filler to improve the strength.

Further, the coating layer 121 may be antistatic-treated. The antistatic treatment may be formed by further forming an antistatic layer on the coating layer 121 or by mixing antistatic particles in the coating layer 121 so that adhesion of atmospheric pollutants on the coating layer 121, Static mark) can be prevented from occurring.

For example, when an antistatic layer is formed on the coating layer 121, the antistatic layer may be formed of an antistatic coating liquid containing a heat or photocurable resin and a conductive polymer in an amount of 3 wt% to 35 wt% based on 100 wt% May be formed on the bottom surface of the coating layer 121.

The conductive polymer contained in the antistatic coating solution may be at least one selected from the group consisting of polyaniline, polypyrrol, polythiophene, polyethylene dioxythiophene, quaternary ammonium compounds, epoxidized amines, fatty acid esters, Wax, a Li-Amide complex, and the like.

The antistatic coating liquid may further include any one of a slip agent, a wetting agent, and a defoaming agent.

Also, the coating layer 121 may be formed to a thickness of 3 to 10 mu m. If the thickness of the coating layer 121 is less than 3 mu m, it may be difficult to exert such effects as scratch resistance.

On the other hand, when the thickness of the coating layer 121 is more than 10 mu m, there is a problem that the production cost of the effect increase is larger.

The backlit sheet 120 as described above includes an image printed by an inkjet method using a white ink together with a four-color ink of cyan-magenta-yellow-black (CMYK) And can print images with fine detail and sharpness. Further, since the adhesive layer 129 contains an ultraviolet screening agent, it is possible to prevent the image from being damaged by ultraviolet rays.

Since the backing sheet 120 is attached to the entire one surface of the plate 110 to prevent scattering of the panel 100, the panel 100 does not need to use tempered glass as the plate 110, The panel 100 having the backing sheet 120 according to the present invention can be manufactured by a simple method and has an advantage that manufacturing cost can be reduced.

In addition, even if the whitet sheet 120 is entirely attached, the panel 100 with the backing sheet 120 attached thereto, which can maintain the transparent property, can be widely used for door frames, shower booths and the like.

In addition, the metal layer 123 may be formed on one side of the base film 125.

Here, the metal layer 123 is formed on one surface of the base film 125 to exhibit a metallic effect of sparkling and luster of the metal during the day through sputtering, vacuum deposition or paste coating, .
