In the present specification, "coating" includes a deposition layer obtained by sputtering a target of a coating material or a printing layer obtained by applying a liquid coating material, but excludes a film adhered through an adhesive. Adhesion includes adhesion using a pressure sensitive adhesive (PSA).

In addition, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The laminate manufacturing method according to the embodiment of the present invention includes a substrate preparation step and a thin film coating layer forming step.

First, in the substrate preparation step, a substrate 110 made of a nonmetal such as glass or a polymer film is prepared. At this time, the glass may be used tempered glass.

Next, as shown in FIG. 1, the forming of the thin film coating layer is a step of forming the thin film coating layer 120 on one surface of the substrate 110. Here, in the thin film coating layer forming step, the thin film coating layer 120 is coated by any one of sputtering, E-beam evaporation, or resistance heating. In the case of depositing the thin film coating layer 120 through sputtering, oxygen or nitrogen gas may be used as the reaction gas. When the sputtering equipment is operated, a coating material is incident from the target 10 toward the substrate 110 to form the thin film coating layer 120. ) Will be deposited. At this time, as shown in (b) of Figure 1, in the thin film coating layer forming step to control the width of the opening (20a) of the screen shield 20 through which the coating material passes through the color difference by position on one surface of the substrate (110) A thin film coating layer 120 is formed. In this case, the screen shield 20 is a device for guiding the coating area of the thin film coating layer 120.

Here, as shown in Figure 2, the coating material by position using the screen shield 20 having an opening 20a made of various shapes, that is, upper, lower asymmetry, left, right asymmetry or upper, lower and middle asymmetry, etc. The deposition number of can be changed. That is, when the thin film coating layer 120 is formed, the substrate 110 moves from the right side to the left side (based on the drawing) while the screen shield 20 is fixed. The wide portion of the opening 20a is the opening 20a. The coating material is thicker and the coating material is deposited thicker than the narrow part of the width), and the narrow part of the opening 20a is lightly deposited by the relatively thin part. As such, when the deposition thickness difference of the coating material is generated for each position, the color and brightness differences are shown for each position of the formed thin film coating layer 120. As shown in FIG. 3, a rich sense of color and depth are visible to the naked eye. Being able to feel and further refine the sophistication, through which, it is possible to improve the design value of the product with a laminate 100 manufactured according to an embodiment of the present invention, to ensure the competitiveness of the product have. At this time, in order to realize the effect of the color difference more prominently, in the thin film coating layer forming step, the thin film coating layer 120 may be formed to a thickness of 3nm ~ 10㎛, preferably 10 ~ 500nm. In the thin film coating layer forming step, the thin film coating layer 120 may be formed as a single layer or a multilayer thin film within the above thickness range.

In the thin film coating layer forming step, at least one of a metal, an oxide, a nitride, an oxynitride, a thermalchromic material, a photochromic material, and an electrochromic material is used for the thin film coating layer 120. The thermochromic material, the photochromic material, and the electrochromic material each have a characteristic of changing color when heat, light, and electricity are applied. For example, the metal layer may be coated with a single layer, the metal layer may be coated with a multilayer, the oxide layer may be coated with a single layer, or the oxide layer may be coated with a multilayer. In addition, the metal layer and the oxide layer may be coated in multiple layers. As an example of the thin film coating layer 40 including the metal layer and the oxide layer, the NbO X coating layer / Aluminum doped Zinc Oxide (AZO) coating layer / Ag coating layer / AZO coating layer / NbO X coating layer is repeated one or more times, for example, once to four times. Can be formed. In addition, VO 2 may be used as the thermochromic material, and the VO 2 thin film and the TiO 2 thin film may be repeatedly formed at least one or more times.

As the metal, for example, stainless steel (SUS 316L, etc.), Cu, Al, Ni, Ti, Nb, Si, Cr, etc. may be used, and the oxide may be an oxide of a metal, TiO 2 , SiO 2 , Ta 2. O 5 , etc. can be used. As the nitride, a metal nitride can be used, and as the oxynitride, a metal oxynitride can be used.

1 to 3 (a) show a prior art, and FIGS. 1 to 3 (b) show an embodiment of the present invention.

Although not shown, a resin pattern layer may be formed on one surface of the substrate 110 before the thin film coating layer 120 is formed. Here, the resin pattern layer may be formed by any one of imprinting, etching, and printing. The resin pattern layer may be a UV curable resin or a thermosetting resin, and may form an uneven pattern, such as linear lines, nonlinear lines, hairspins, hairlines, scratches, crosshatching, textures, and embossing (textures). emboss), prisms, grooves, lenses, pillars, cones, polygons, holes, etc. Moreover, it can form so that a resin pattern layer may have a 3D three-dimensional pattern. For example, the 3D pattern may be realized by forming a concave-convex pattern in which the depth of the concave portion and the height of the convex portion are not constant. To this end, a resin pattern layer may be formed by imprinting using a mold having a reversed phase of a 3D three-dimensional pattern. In addition, it is possible to form a resin pattern layer through a multi-layer coating, by changing the 2D pattern of each layer to form a resin pattern layer having a three-dimensional solid pattern, by etching the substrate 110 to form a resin pattern layer The resin pattern layer having the 3D three-dimensional pattern may be formed by varying the etching depth at each position. And in order to give a color, resin containing a pigment, such as a pigment, can also be used.

In addition, the resin pattern layer and the thin film coating layer 120 may be formed only on a partial area of the substrate 110. For example, in the case of a mobile phone display window, the resin pattern layer and the thin film coating layer 120 are formed only at the edge of the substrate 110 to give a decoration effect, and the central portion of the substrate 110 is a simple transmission through which the display screen can pass. It will function as a window.

In addition, the protective film may be adhered on the thin film coating layer 120. Here, the protective film is not only to secure physical durability, such as to prevent scratches of the thin film coating layer 120, but has an effect of maintaining the chemical durability of the thin film coating layer 120. Such a laminate 100 is typically attached to household appliances, where a polyurethane adhesive may be used. Therefore, the protective film may perform a function of improving chemical durability by blocking a chemical reaction between the polyurethane adhesive and the thin film coating layer 120.

Such a protective film may have a transparent, achromatic or chromatic color. For example, when there is a risk that the color of the adhesive on the back of the protective film according to the embodiment may be exposed on the front surface of the laminate 100, by giving a white color to the protective film may be the color of the adhesive is not exposed on the front. .

In addition, the first protective coating layer may be printed on the thin film coating layer 120 instead of the protective film. Here, at least one of Si 3 N 4 , SiC, NbOx, TiN, Ti, and DLC may be used as the first protective coating layer. This first protective coating layer can be formed by CVD, sputtering, or the like.

In addition, in the embodiment of the present invention, a second protective coating layer may be formed between the thin film coating layer 120 and the protective film or the thin film coating layer 120 and the first protective coating layer. Here, at least one of Ti, TiO 2 , Si, SiO 2, Ta 2 O 5 , Nb, and NbO x may be used as the second protective coating layer, and a rainbow pattern may be generated on the laminate 100 through the second protective coating layer. The phenomenon can be prevented.

In addition, in the embodiment of the present invention it is possible to laminate the primer coating layer on the resin pattern layer. In this case, at least one of Ti, Nb, Si, TiOx, NbOx, and SiOx may be used as the primer coating layer. And the primer coating layer is preferably formed to a thickness of 5 ~ 500nm. This primer coating layer may be deposited through sputtering. The primer coating layer serves to suppress a phenomenon in which a color difference occurs due to a chemical reaction between the thin film coating layer 120 and the resin pattern layer.

In addition, in the embodiment of the present invention, an antifouling coating layer may be formed on the other surface of the substrate 110, that is, on the entire surface of the substrate 110 based on the observer. That is, in the laminate 100, the antifouling coating layer is a layer exposed to the outside, thereby protecting the inner layer from the external environment. In this case, at least one of MgF 2 , PTFE (polytetrafluroethylene), DLC (Diamond Like Carbon) and TiO 2 may be used as the antifouling coating layer, and a small amount of impurities may be doped into the antifouling coating layer to improve its performance. The antifouling coating layer serves to prevent the laminate 100 from being contaminated by performing a hydrophilic function, a photocatalytic function, and the like.

As such, the laminate 100 according to the embodiment of the present invention to be manufactured is typically in the form of being attached to an outer wall surface of a home appliance, for example, but is not necessarily limited thereto. For example, it may be attached to the interior wall of the refrigerator to form part of the interior design. In addition, although the laminate 100 of the present invention has been described as a main embodiment attached to a home appliance, of course, it is not limited thereto. For example, the field of application of the laminate 100 manufactured according to the embodiment of the present invention covers various fields such as mobile phones, household goods, furniture, building windows, automobiles, and the like.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill 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. This is possible.

Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the scope of the appended claims as well as the appended claims.
