[0002]
[Prior art]
Conventional decorative sheets to be attached to window glass, etc. include colored film, half-deposited film (aluminum-deposited film with a light transmittance of 15% to 50%), or uncolored transparent 2. Description of the Related Art There is known a film obtained by performing aluminum vapor deposition with transparency on a light diffraction film formed by forming a light diffraction surface on one side of a film. In many cases, the film is light-shielded or decorated by sticking this film on the inside of a window glass of an automobile.
[0003]
[Problems to be solved by the invention]
However, the colored film and the half-deposited film as described above are lacking in terms of decorativeness because they are silver or other single color. In addition, the film with aluminum vapor deposition that is transparent to the light diffraction film is very effective in decoration because the reflected light changes to rainbow color depending on the viewing angle, but this film is placed inside the window glass. If pasted, the interior may be filled with red, other monochromatic light, or silver due to the influence of external light, and also looks silvery when viewed from the inside of the car, causing discomfort and discomfort. There is a disadvantage that it occurs.
[0004]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on the illustrated embodiment.
[0007]
FIG. 1 is an enlarged cross-sectional view showing an embodiment of a decorative sheet according to the present invention. In this decorative sheet, a colored transparent first pressure-sensitive adhesive layer 2 and a non-colored transparent resin film layer 3 are sequentially laminated on one side of a multilayer structure film body 1 composed of a large number of laminated films. The second adhesive layer 4 having transparency and a release film (separator) 5 are sequentially laminated on the other surface side of the multilayer film body 1.
[0008]
As shown in the enlarged sectional view of FIG. 4, the multilayer structure film body 1 is a multilayer structure in which about several tens to several hundreds of films are laminated through a transparent adhesive (not shown). The thickness of the structural film body 1 is, for example, about 20 μm. And each film which comprises has transparency, does not contain a pigment | dye, and has not performed metal vapor deposition. This multilayer structure film body 1 is a selective wavelength reflection film body by structural color development, and utilizes multiple reflection at a specific wavelength due to optical path difference interference of each layer. Thereby, it has the property to reflect so that visible rays, such as sunlight, may be changed into a rainbow color according to the viewing angle. That is, since color is not developed by dyes or metal vapor deposition, color deterioration and fading do not occur.
[0009]
The decorative sheet shown in FIG. 1 is formed as follows. First, a fluid pressure-sensitive adhesive is applied to one side of the multilayer structure film body 1 to form the first pressure-sensitive adhesive layer 2, and the resin film layer 3 is pasted thereon.
The first adhesive layer 2 is formed of a colored adhesive and is set to have a predetermined visible light transmittance after drying. The light transmittance of the first adhesive layer 2 is preferably set to be 3% to 70%. The first pressure-sensitive adhesive layer 2 that is colored and transparent has an appropriate light-shielding property and is colored in a color tone that does not cause discomfort or discomfort.
[0010]
The material of the transparent resin film layer 3 is, for example, polyethylene terephthalate (PET) or acrylic, but may be other types of resins.
By coloring the pressure-sensitive adhesive as in the present invention, a colored layer can be formed without wasting materials, which is very economical.
Moreover, in FIG. 1, the hard coat process is performed in the further outer surface of the resin film layer 3, and the protective layer 7 is formed. Thereby, the resin film layer 3 which is easily damaged can be protected, and a durable decorative sheet can be formed.

[0013]
Thereby, a part of the light that enters through the window glass 8 from the outdoors (b side) is reflected to the outdoors by the multilayer structure film body 1. Then, the reflected light changes to a rainbow color depending on the viewing angle of a person who is outdoors, and can exhibit excellent decorativeness. Moreover, since the colored 1st adhesion layer 2 is located in the vehicle center side (a side) rather than the multilayer structure film body 1, the multilayer structure film body 1 and the 1st adhesion layer 2 moderate light from the outdoors. Can be shielded from light.
[0014]
Moreover, when the light from the outdoor side passes through the multilayer structure film body 1, depending on the angle at which the light enters, light that feels uncomfortable or uncomfortable, such as iridescent or red, will pass. However, the colored first pressure-sensitive adhesive layer 2 prevents such iridescent or monochromatic light from entering the vehicle. The coloring of the first pressure-sensitive adhesive layer 2 (brown type) makes the room a calm color. be able to.
Moreover, the 2nd adhesion layer 4 is good also as non-colored transparent and colored transparency. When it is colored and transparent, the transmittance is preferably lower than that of the first pressure-sensitive adhesive layer 2, whereby a subtle change can be given to the light reflected in the rainbow color.
