Description

  The present invention relates to home appliances such as televisions, videos, refrigerators, washing machines, stereos, mirror products such as compact mirrors for makeup, vehicles such as automobiles, ships, aircraft, buildings, play equipment (ski goggles, etc.), and other various types. The present invention relates to a nameplate working sheet for producing nameplates (including display plates and panels) having a metallic luster used in machinery and the like.

  As a nameplate working sheet body with this kind of metallic luster, conventionally, a transparent substrate is subjected to a hard coat treatment, a masking film is formed on the hard coat layer, and a metal is deposited on the masking film to deposit a metal. A structure in which a film is formed and a top coat layer is further formed thereon is disclosed (paragraphs [0028]-[0034] and FIG. 4 of Patent Document 1).

However, in the structure in which the metal vapor deposition is performed in the manufacturing process of the nameplate production sheet body in this way, when forming the metal vapor deposition film, it is unavoidable to process by a single wafer type that handles each transparent substrate. For this reason, continuous operation cannot be performed, production efficiency is poor, and it is difficult to widen the sheet. In addition, since the number of processes increases, it is difficult to manage foreign matters and scratches, resulting in poor yield.
JP 2001-266687 A

  Accordingly, the present invention relates to a nameplate working sheet body having a metallic luster, and provides a new nameplate working sheet body and a method for producing the same that can be produced simply and in large quantities with good yield.

  In the present invention, a metallic gloss film having a metallic luster is attached to one side of a transparent substrate via an adhesive layer, and a hard coat is applied to the other side of the transparent substrate via an adhesive layer. A nameplate working sheet body having a structure formed by sticking a treated hard coat film is proposed.

  The nameplate working sheet body having such a configuration has a hard coat film on the front side of the transparent substrate and a metallic gloss film on the back side, and therefore utilizes light refraction due to the thickness of the transparent substrate and glossiness due to the metallic gloss film. The appearance can be shown in a deep metallic tone. Furthermore, the metallic gloss surface of the metallic gloss film can be protected from scratches and the like.

When the nameplate production working sheet body having the above configuration is for producing a colored nameplate, among the transparent substrate, the adhesive layer on one side, the metallic gloss film, the adhesive layer on the other side, and the hard coat film At least one of them is configured to contain a color material, or a colored layer is laminated on one side or both sides of at least one of a transparent substrate, a hard coat film, and a metallic gloss film. It is preferable to constitute such that
If comprised in this way, when viewing from the hard coat film side to the metallic gloss film, a layer containing a colored layer or a coloring material is provided between any constituent layers. By utilizing the glossiness of the glossy film and the hue of the colored layer, the appearance can be shown in a deep color metallic tone. Conventionally, in order to produce a colored nameplate, screen printing was performed either before or after the hard coat treatment, and then a method of performing a vapor deposition process or color development by multilayer thin film coating utilizing the light interference phenomenon was performed, Compared with these methods, the number of steps is simple, the yield is good, and the manufacturing cost can be suppressed.

  In addition, by performing black printing on one side of the metallic glossy film, specifically, the entire surface or part of the surface in contact with the air layer, the transmittance of that part of the metallic glossy film is reduced and a mirror-like appearance is obtained. The design can be further improved. In addition, since it has excellent durability, it can be used as nameplates (including display panels for various products) and parts such as home appliances.

  Furthermore, the nameplate production working sheet of the present invention is an extension line of a production line that continuously forms a transparent substrate by an extrusion method or a continuous casting method, and a metallic gloss film is applied to a pressure roller on one side of the transparent substrate. On the other hand, since a hard coat film can be bonded to the other side surface of the transparent substrate with a pressure roller to continuously manufacture a nameplate working sheet body, it is possible to produce efficiently. Further, it is easy to widen the sheet body, and since the number of processes is small, it is possible to enjoy the benefits of easy management of foreign matters and scratches and good yield. Furthermore, by laminating the respective films via the adhesive layer, the impact stress during the punching process can be relaxed, and the workability during the production of the nameplate can be improved.

Next, this invention is demonstrated based on embodiment.
