（本発明の一実施の形態の基本態様）
次に、本発明にかかる装飾用薄物の一実施の形態の基本態様について図１を参照して説明する。
この一実施の形態の基本態様に示す装飾用薄物１はＰＥＴ樹脂層である受理層２を有する。この受理層２はＰＥＴ樹脂層に代えてＰＭＭＡ樹脂層又はＰＣ樹脂層又はＵＶ硬化樹脂層とすることもできる。受理層２の光入射側には無色透明の接着層３が積層され、その接着層３の光入射側に無色透明のＰＥＴ樹脂であるベースフィルム４が積層される。ベースフィルム４はＰＥＴ樹脂に代えてＰＭＭＡ樹脂又はＰＣ樹脂とすることもできる。また、接着層３及びベースフィルム４は有色としても良い。受理層２の接着層３に対する反対側の側面には蒸着層５が設けられ、その蒸着層５に型材料に接合するための透明な接着層６が設けられる。蒸着層５を印刷層や塗装層に代替し、若しくは併用することは実施の態様によって適宜行うことができる。
( Basic aspect of one embodiment of the present invention)
Next, a basic aspect of an embodiment of a decorative thin object according to the present invention will be described with reference to FIG.
The decorative thin object 1 shown in the basic mode of this embodiment has a receiving layer 2 which is a PET resin layer. The receiving layer 2 may be a PMMA resin layer, a PC resin layer, or a UV curable resin layer instead of the PET resin layer. A colorless and transparent adhesive layer 3 is laminated on the light incident side of the receiving layer 2, and a base film 4 that is a colorless and transparent PET resin is laminated on the light incident side of the adhesive layer 3. The base film 4 may be PMMA resin or PC resin instead of PET resin. The adhesive layer 3 and the base film 4 may be colored. A vapor deposition layer 5 is provided on the side surface of the receiving layer 2 opposite to the adhesive layer 3, and a transparent adhesive layer 6 for bonding to the mold material is provided on the vapor deposition layer 5. Substituting or using the vapor deposition layer 5 with a printing layer or a coating layer can be appropriately performed according to the embodiment.
各層の厚みは、受理層２が１０〜２５０μｍ、蒸着層５が、蒸着層であれば約０．４μｍ、印刷層であれば約１０μｍ、接着層３及び接着層６が約５μｍ、ベースフィルム４が２５〜１５０μｍとする。したがって、装飾用薄物１全体は３８．２〜３８１μｍの厚みを有する。 The thickness of each layer is 10 to 250 μm for the receiving layer 2, about 0.4 μm for the vapor deposition layer 5, about 10 μm for the printing layer, about 5 μm for the adhesive layer 3 and the adhesive layer 6, and the base film 4. Is 25 to 150 μm. Accordingly, the entire decorative thin object 1 has a thickness of 38.2 to 381 μm.
受理層２は厚み１０〜２５０μｍの範囲で厚みの大なる部分２ａと厚みの小なる部分２ｂとを有するようにその厚みに変化が設けられている。その結果、受理層２の蒸着層５側の側面は波の高さが３〜２４０μｍの範囲で変化する波状の変化を有する境界面２ｃとなる。 The thickness of the receiving layer 2 is changed so as to have a portion 2a having a large thickness and a portion 2b having a small thickness within a range of 10 to 250 μm. As a result, the side surface of the receiving layer 2 on the vapor deposition layer 5 side becomes a boundary surface 2c having a wavy change in which the wave height changes in the range of 3 to 240 μm.
またその受理層２の厚み変化には１／ｆゆらぎを付与することにより、光反射による輝度にランダムに変化する明暗を生じさせる。すなわち受理層２の厚み変化は数１に示す１／ｆゆらぎ関数ｆ（ｘ）より決定される。 Further, by giving 1 / f fluctuation to the thickness change of the receiving layer 2, light and darkness that randomly changes in luminance due to light reflection is generated. That is, the thickness change of the receiving layer 2 is determined by the 1 / f fluctuation function f (x) shown in Equation 1.
以上の一実施の形態の基本態様の装飾用薄物１によれば、ベースフィルム４に対する入射光の方向又はベースフィルム４に対する視点を相対的に変化することにより、生成される反射輝度に、木漏れ日に似た不規則に変化する明暗パターンを生じせることができる。従って、装飾が必要なパネル（図示せず）に接着層６によって接着することにより、変化に富んだ見栄えの良い光装飾が可能になる。 According to the decorative thin object 1 of the basic aspect of the above embodiment, by changing the direction of the incident light with respect to the base film 4 or the viewpoint with respect to the base film 4, the reflected brightness generated can be reduced to the sunbeams. Similar irregularly changing light and dark patterns can be produced. Therefore, by adhering to a panel (not shown) that requires decoration by the adhesive layer 6, it is possible to provide a light decoration that is rich in change and good in appearance.
しかも、接着する対象となるパネルは特には限定されないことから一の装飾用薄物１を情報機器（ノートパソコン、パソコン、携帯電話、スマートフォン等）、家電製品（冷蔵庫、洗濯機、エアコン等）、自動車用内装部品（センターパネル、ドアモール等）、及びＡＶ機器（ＴＶ、ＤＶＤ／ＨＤＤデッキ等）等のパネルの何れにも適用することができる。従って、汎用性が高く量産効果によるコストダウンを図ることができる。
図２は以上の一実施の形態の基本態様の装飾用薄物１をベースフィルム４側から撮影した写真である。
In addition, since the panel to be bonded is not particularly limited, one thin decorative object 1 is used for information devices (notebook computers, personal computers, mobile phones, smartphones, etc.), home appliances (refrigerators, washing machines, air conditioners, etc.), automobiles. It can be applied to any of interior panels (center panel, door molding, etc.) and panels of AV equipment (TV, DVD / HDD deck, etc.). Therefore, the versatility is high and the cost can be reduced due to the mass production effect.
FIG. 2 is a photograph taken from the base film 4 side of the decorative thin object 1 according to the basic aspect of the above embodiment .
この写真に示すように受理層２からの反射光は波状の変化を有する木漏れ日に似た不規則に変化する明暗パターンを生じさせる。
なお、以上の一実施の形態の基本態様の装飾用薄物１を複数積層して一の装飾用薄物（図示せず）とすることができる。その場合に積層される各装飾用薄物１のうちの一の受理層２を有色透明とし、他を無色透明とするなどの多様なアレンジは実施の態様に応じて適宜行うことができる。
As shown in this photograph, the reflected light from the receiving layer 2 gives rise to an irregularly changing light and dark pattern similar to the sun leaking day having a wavy change.
It should be noted that a plurality of decorative thin objects 1 according to the basic embodiment of the above-described one embodiment can be laminated to form one decorative thin object (not shown). In this case, various arrangements such as making one receiving layer 2 out of each decorative thin object 1 laminated colored and transparent, and making the other colorless and transparent can be appropriately performed according to the embodiment.
また、実施の態様によってはベースフィルム４にさらにＰＭＭＡ樹脂層及びＰＣ樹脂層及びハードコート層及びＡＢＳ樹脂層のうちの少なくともいずれか一を一体的に積層したものを装飾用薄物１とすることもできる。 Further, depending on the embodiment, the decorative thin object 1 may be formed by integrally laminating at least one of the PMMA resin layer, the PC resin layer, the hard coat layer, and the ABS resin layer on the base film 4. it can.
