Problems solved by technology

[0006] However, the laminated body for producing a nameplate having the structure disclosed in the above-mentioned Patent Document 1 must be manufactured in a single-sheet type in which metal vapor deposition is performed on each transparent plate when forming a metal vapor deposition film. Therefore, there are the following problems: It is difficult to produce continuously on a series of production lines, and the productivity is low. In addition, if the width of the thin plate is increased, deflection and deformation will occur, and the productivity will decrease. In addition, due to the increase in the number of processes, the management of foreign matter and damage will become difficult. Yield also decreases
For example, when the reflected image is observed against a fluorescent lamp, there is a problem that numerous pockmarks like orange peel texture appear on the surface of the laminate.
[0008] In addition, when metal transfer foil is used for transfer foil coating, since unevenness (coating unevenness) occurs at the interface between the anticorrosion layer and the metal layer or the interface between the metal layer and the adhesive layer, etc., there may be The problem of distortion of reflected light in the metal transfer foil itself
[0009] In this way, although in-mold injection molded products using metallic luster films or metal transfer foils can be produced relatively inexpensively, they have a problem of poor design compared with the case of directly vapor-depositing metal on a transparent substrate.

no. 1 approach

[0038] As a first embodiment, as shown in FIG. 1 , an adhesive layer 2 is sequentially stacked on the back side of a transparent substrate 1 (the back side seen from the observation side, that is, the side opposite to the observation side, that is, the front side). A laminated body A for producing a nameplate having a laminated structure constituted by the metal vapor-deposited film 3 will be described.

[0039] (transparent substrate 1)

[0040] The transparent substrate 1 is not particularly limited as long as it is a transparent and flat plate, and its shape and material are not particularly limited. However, it is preferably made of a transparent resin that can achieve weight reduction or thinning. Specifically, polymethyl methacrylate (PMMA) resin, polycarbonate (PC) resin, methyl methacrylate-styrene copolymer resin (MS resin), polyarylate resin, polysulfone resin, polyether A transparent substrate mainly composed of at least one of sulfone resin, norbornene-based resin...

no. 2 approach

[0086] As a second embodiment, as shown in FIG. 2 , an adhesive layer 2 and a metal vapor-deposited film 3 are sequentially laminated on the back side of a transparent substrate 1 , and a hard coat film 7 is laminated on the front side of the transparent substrate 1 via an adhesive layer 6 . The laminated body B for making a nameplate with a laminated structure is described, that is, the laminated body for making a nameplate having a laminated structure in which a hard coat film 7 is laminated via an adhesive layer 6 on the surface side of the laminated body A for nameplate making is described. Body B will be described.

[0087] The transparent substrate 1, the adhesive layer 2, and the vapor-deposited metal film 3 are the same as those of the above-mentioned laminated body A for producing a nameplate. In addition, the same adhesive layer as the adhesive layer 2 may be used for the adhesive layer 6 .

[0088] In addition, when adding a coloring agent to the adhesive layer, it...

no. 3 approach

[0110]As shown in Fig. 5 and Fig. 6, the laminated body C for making a nameplate as the third embodiment has a transparent substrate 1 made of synthetic resin on the back side (the back side seen from the observation side, that is, the same side as the observation side). The side opposite to the surface side) is a nameplate-making laminate having a laminated structure in which an adhesive layer 2 and a metal vapor-deposition film 3 are sequentially laminated, and a modified PET film 4A is used as a base film of the metal vapor-deposition film 3 .

[0111] (transparent substrate 1)

[0112] As the transparent substrate 1 , a substrate made of synthetic resin among the transparent substrates 1 described in the first embodiment can be used.

[0113] When the transparent substrate 1 is made of synthetic resin, warping in a high-temperature environment becomes a problem. However, in the present embodiment, by using a predetermined modified PET film , can prevent warping under high...

Abstract

The invention provides a laminate for name plate preparation that is free from distortion (fluctuation) in reflected light and has a high level of design. The laminate for name plate preparation is a laminate having metallic luster, comprising a transparent substrate (1) and a pressure-sensitive adhesive layer (2) and a metal deposited film (3) provided in that order on the backside of the transparent substrate (1). The metal deposited film (3) comprises a metal deposition layer (5) provided on the surface side of a transparent resin film (4), and, at the same time, the thickness of the transparent resin film (4) was specified to not less than 175 m and not more than 300 m. Specifying the thickness of the transparent resin film (4) located on the backside of the metal deposition layer (5) can eliminate the occurrence of distortion (fluctuation) of reflected light and, when a person sees a reflected image of a fluorescent lamp, can render pockmarks like orange peel unseenable.

Description

technical field [0001] The present invention relates to a laminated body for making nameplates with a metallic luster, which is used for making home appliances such as televisions, refrigerators, washing machines, and stereos, mirror products such as cosmetic pocket mirrors, vehicles such as motor vehicles, ships, airplanes, and buildings , play equipment (ski goggles, etc.), and nameplates (including display boards and panels) used in various other mechanical devices. Background technique [0002] As a nameplate-making laminate having such a metallic luster, conventionally, a structure is disclosed in which a hard coat is applied to a transparent substrate in order to improve adhesion to a metal vapor-deposited film, and the hard coat is coated with A masking film (masking film) is formed on the masking film, metal vapor deposition is performed on the masking film to form a metal vapor deposition film, and an overcoat layer is formed on the metal vapor deposition film to co...
