BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail based on the illustrated embodiments.
[0007]
FIG. 1 is an enlarged sectional view showing an embodiment of the decorative sheet according to the present invention. This decorative sheet is formed by sequentially laminating a colored transparent first adhesive layer 2 and a non-colored transparent resin film layer 3 on one side of a multilayer structure film body 1 composed of a multiplicity of laminated films. A second adhesive layer 4 having transparency and a release film (separator) 5 are sequentially laminated on the other surface side of the multilayer structure film body 1.
[0008]
As shown in the enlarged cross-sectional view of FIG. 4, the multilayer structure film body 1 is a multilayer laminate structure in which about several tens to several hundreds of films are laminated via a transparent adhesive (not shown). The thickness of the structural film body 1 is, for example, about 20 μm. Each of the constituent films has transparency, does not contain a pigment, and is not subjected to metal evaporation. This multilayer structure film body 1 is a selective wavelength reflection film body based on structural coloring, and utilizes multiple enhanced reflection of a specific wavelength due to optical path difference interference of each layer. Thereby, it has a property of reflecting visible light such as sunlight so as to change to a rainbow color depending on a viewing angle. That is, since the color is not formed by the deposition of a dye or metal, color deterioration and fading do not occur.
[0009]
And the formation of the decorative sheet shown in FIG. 1 is performed as follows. First, a fluid adhesive is applied to one side of the multilayer structure film body 1 to form a first adhesive layer 2, and a resin film layer 3 is attached 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 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 resin.
By coloring the pressure-sensitive adhesive as in the present invention, a colored layer can be formed without wasting the material, which is very economical.
In FIG. 1, a hard coat treatment is applied to the outer surface of the resin film layer 3 to form a protective layer 7. Thereby, the resin film layer 3 that is easily damaged can be protected, and a durable decorative sheet can be formed.
[0011]
Next, a fluid adhesive is applied to the other surface side of the multilayer structure film body 1 to form a second adhesive layer 4, and then a release film 5 is attached to the second adhesive layer 4. Thus, the decorative sheet is completed.

Paste on. That is, the decorative sheet is attached to the inner surface of the vehicle.
Therefore, the one side of the multilayer structure film 1 of the decorative sheet 1 (the side on which the first adhesive layer 2 is formed) is the center side in the vehicle, and the other side is the second adhesive layer 4. This side is the side of the vehicle interior window glass.
[0013]
As a result, part of the light that enters through the window glass 8 from outside (b side) is reflected outside by the multilayer structure film body 1. The reflected light changes to a rainbow color depending on the viewing angle of a person outdoors, and it is possible to exhibit excellent decorativeness. In addition, since the colored first adhesive layer 2 is located on the center side (a side) in the vehicle with respect to the multilayer structure film body 1, the multilayer structure film body 1 and the first adhesive layer 2 can moderate the light from the outdoors. Can be shielded from light.
[0014]
Further, when light from the outdoor side passes through the multilayer structure film body 1, depending on the angle at which the light enters, light such as iridescent or red, which feels uncomfortable or uncomfortable, passes. However, the colored first adhesive layer 2 prevents such rainbow-colored or monochromatic light from entering the vehicle, and the interior of the room is set to a calm color by the coloring (brown-based) of the first adhesive layer 2. be able to.
The second adhesive layer 4 may be non-colored and transparent or colored and transparent. When it is colored and transparent, it is preferable that the transmittance is lower than that of the first adhesive layer 2, whereby a subtle change can be given to the light reflected in rainbow colors.
[0015]
Next, FIG. 2 is an enlarged sectional view showing another embodiment of the decorative sheet of the present invention. In this decorative sheet, a printed layer 6 is formed on one surface side of a multilayer structure film body 1 composed of a multiplicity of laminated films, and further a colored transparent first adhesive layer 2 and a non-colored transparent resin film layer are formed. 3 are sequentially laminated, and a second adhesive layer 4 having transparency and a release film (separator) 5 are sequentially laminated on the other surface side of the multilayer structure film body 1.

The light transmittance of the first adhesive layer 2 is preferably set to be 3% to 70%. The first 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.
[0017]
In addition, the printing layer 6 is printed in a color different from the color (color) of the first adhesive layer 2 so as to have transparency, or is opaque (having no transparency), and other colors. For example, the first adhesive layer 2 may have the same (similar) color as the coloring of the first adhesive layer 2 and be opaque, or have a different transmittance from the first adhesive layer 2.
[0018]
The material of the transparent resin film layer 3 is, for example, polyethylene terephthalate (PET) or acrylic, but may be other types of resin. By coloring the pressure-sensitive adhesive as in the present invention, a colored layer can be formed without wasting the material, which is very economical.
Further, in FIG. 2, a hard coat treatment is applied to a further outer surface of the resin film layer 3 to form a protective layer 7. Thereby, the resin film layer 3 that is easily damaged can be protected, and a durable decorative sheet can be formed.
