製品を得ること°は困難であった。However, when a colored layer that does not have metallic luster is provided on the back side of a transparent plastic plate, even if there is embossing between the colored layer and the transparent plastic, in order to give the colored layer a hiding effect, it is necessary to It is necessary to make the thickness thicker than the unevenness of the embossing, and as a result, due to the hiding effect (light absorption) of the colored layer, it becomes difficult to detect the presence of the embossing from the surface of the transparent plastic plate. It was difficult to obtain a product that could be used.

い。Furthermore, when forming a colored layer using a thermoplastic resin, if you try to apply it to a plastic plate by a transfer method, even if the colored layer is embossed in advance, it will be deformed by the heat during transfer. The desired effect cannot be obtained, and
When the colored layer is formed of a thermosetting resin, hot stamp adhesion between the colored layer and the plastic plate cannot be obtained, and a separate adhesive layer must be interposed. Selection of this adhesive is extremely difficult, and light reflection at the interface between the adhesive resin and the colored layer resin cannot be expected due to the proximity of the refractive index, making it difficult to obtain the desired embossed appearance. Can not.

く求められている。Problems to be Solved by the Invention A structure in which a colored layer with an embossed appearance can be seen through a transparent plastic plate is strongly desired for plates in various home appliances. Even if a colored layer is applied to a plastic plate, a practical product cannot be obtained, and further development is strongly required.
そこで、本発明では、このような従来法の欠点を解消し

を存する製品を得ることができるのである。'Means for solving the problem In the present invention, the above object is achieved by providing a light-shielding colored layer on the back surface of a transparent plate through a metal thin film having a light transmittance of 30 to 85%. By subjecting the metal thin film to embossing, it is possible to obtain a product that has an appearance as if the embossing was provided directly on a light-shielding colored layer.

きるものである。Function: In the present invention, the light transmittance is 30~30 without giving the impression of metallic luster.
Ultra-thin gold Km of 85% (preferably 45-70%)
By embossing the film and providing a light-shielding colored layer on the back side, the partial light reflection of the metal thin film and the light absorption of the colored layer are appropriately combined, allowing the thin metal film to pass through the transparent plate. Its presence is virtually imperceptible, and it is possible to obtain an appearance as if the embossing was applied directly onto the colored layer.

も、所望のエンボス効果を得ることができるのである。Embossing on a metal thin film is usually preferably performed on a transfer base material, but it may also be performed on a transparent plate. For example, a metal thin film is formed on a transfer base material and embossing is performed on it. In addition to forming a metal thin film on an embossed transfer substrate, forming a smooth metal thin film layer on a transparent plate and embossing the metal thin film layer, or embossing on a transparent plate. The metal thin film has a light transmittance of 30 to 85%, which is very thin (depending on the metal used, but it is usually much different from the unevenness of embossing). Therefore, the desired embossing effect can be obtained by any of the methods described above.

透視できる非常に妙味ある製品を得ることもできる。As for the embossing, it is preferable to apply a fine pattern such as a hairline shape, a matte shape, or a matte texture, and in the present invention, the metal thin film subjected to such embossment is arranged in a pattern on a transparent plate. By providing a colored layer with hiding properties to cover it, or by partially embossing the gold Wk thin film, the partially embossed plain patterned colored layer becomes transparent. You can also get very interesting products that can be seen through the board.

Using a product that has undergone hairline processing of approximately 6 μm, a release layer and a vapor deposition anchor layer mainly composed of acrylic resin are sequentially formed on the hairline processing surface by gravure coating, and then metal Cr is coated by vacuum evaporation method. Apply a thin film to increase the light transmittance of the entire film to 48-55%.
And so. The amount of metal Cr deposited in this case is on average 44
Furthermore, a transparent hot-melt adhesive layer made of vinyl chloride/vinyl acetate copolymer resin and acrylic resin was formed on this vapor-deposited layer by reverse roll coating to form a transfer foil. .

It became. Thereafter, a black coating film having a thickness of 9 μm was formed as a concealing layer on the transfer surface by screen printing. As a result, the transparent acrylic plate had an appearance in which the black layer had a clear hairline pattern when viewed from the side where the colored layer was not present.

The light transmittance of the entire film was set to 65 to 70%. The amount of metal Cr deposited in this case was 23 mg/ll' on average. A transparent real-melt adhesive layer was further formed on this vapor-deposited layer by reverse roll coating in the same manner as in Example 1, thereby forming a transfer foil.
