Japanese Patent Laid-Open No. 11-432

従来の装飾材のほとんどは合成樹脂の成形品であるので、その形状はきわめて多様であったが、色彩等の光学的な効果は上記のような公知の手法によっていたので、新鮮さを出すことが困難であった。 Since most of the conventional decorative materials are molded products of synthetic resin, their shapes were very diverse. However, the optical effects such as color were based on the above-mentioned known methods, so that freshness was achieved. It was difficult.

請求項１記載の装飾材は、合成樹脂薄膜を接着層を介して積層して構成され光干渉多層膜として機能する多層膜フィルムを立体的に成形してなることを特徴とするので、従来の装飾材には無かった斬新な光学的（視覚的）効果をもたらす。 Since the decorative material according to claim 1 is formed by three-dimensionally forming a multilayer film that is formed by laminating a synthetic resin thin film via an adhesive layer and functions as an optical interference multilayer film, It provides a novel optical (visual) effect that was not found in decorative materials.

光干渉多層膜（光多層膜、光干渉フィルタ）は、屈折率（誘電率）が異なる薄膜を交互に積層してなり、屈折率と膜厚とに応じて特定の波長域の光を選択的に透過或いは反射させることができる。この性質から、フィルタや反射フィルム等に利用されている（例えば特開平５−２４１０１７号公報、特開平７−２０３１３号公報、特開２００１−１３５１２２号公報、特開２００２−２３１０３８号公報）。ただし、石英ガラス等の基板上に例えば酸化チタン（ＴｉＯ₂）と二酸化珪素（ＳｉＯ₂）とを交互に積層してなる光干渉多層膜は、例えば屈曲させて立体的な形状にすることはできなかった。 An optical interference multilayer film (optical multilayer film, optical interference filter) is made by alternately laminating thin films with different refractive indexes (dielectric constants), and selectively selects light in a specific wavelength range according to the refractive index and film thickness. Can be transmitted or reflected. Because of this property, it is used for filters, reflection films, and the like (for example, JP-A-5-241017, JP-A-7-20313, JP-A-2001-135122, JP-A-2002-231038). However, an optical interference multilayer film in which, for example, titanium oxide (TiO ₂ ) and silicon dioxide (SiO ₂ ) are alternately laminated on a substrate such as quartz glass can be bent into a three-dimensional shape, for example. There wasn't.

請求項１記載の装飾材においては、合成樹脂薄膜を接着層を介して積層して構成され光干渉多層膜として機能する多層膜フィルムを採用しているので、これを例えば真空成形、圧空成形、真空圧空成形等の手法にて容易に立体的に成形することができる。 In the decoration material according to claim 1, since a multilayer film functioning as an optical interference multilayer film is formed by laminating a synthetic resin thin film through an adhesive layer, this is formed by, for example, vacuum forming, pressure forming, It can be easily three-dimensionally formed by a technique such as vacuum / pressure forming.

そして、ここが大きな特徴となるのだが、もともとは各層の厚さが正確に制御されていた多層膜フィルムの層構造が立体的に成形される際に歪んで全体的に不均一になる。例えば曲げ半径の小さいコーナー部分では多層膜フィルムに引き延ばし方向の力が大きく作用するので歪みも大きいが、平面に近い部分ではそうはならない。したがって、装飾材の各部分で透過或いは反射させる波長域が変化し、虹状の干渉縞が発現されたり、ある波長域が強調されて反射されたり、或いはほとんど透明になったりする等様々な光学的な変化が全体的に現れる。これにより、従来の着色による手法では実現できなかった斬新な装飾効果が得られる。しかも、多層膜フィルム自体には着色する必要がない。 And this is a major feature, but when the layer structure of the multilayer film, in which the thickness of each layer is originally accurately controlled, is three-dimensionally formed, it is distorted and becomes uneven overall. For example, at the corner portion where the bending radius is small, the force in the extending direction acts on the multilayer film so that the distortion is large. Therefore, the wavelength range to be transmitted or reflected in each part of the decorative material changes, and various optical optics such as rainbow-like interference fringes appear, a certain wavelength range is emphasized and reflected, or almost transparent. Changes appear throughout. As a result, a novel decoration effect that cannot be realized by the conventional coloring method can be obtained. Moreover, it is not necessary to color the multilayer film itself.

このような優れた装飾効果が得られる多層膜フィルムとしては、ポリエチレンテレフタレート（ＰＥＴ）の薄膜を、０．１ｍｍ（厚さ）当たりで２００〜３００層積層してなる、請求項４の多層膜フィルムがある。 The multilayer film according to claim 4, wherein the multilayer film having such an excellent decorative effect is formed by laminating 200 to 300 layers of a thin film of polyethylene terephthalate (PET) per 0.1 mm (thickness). There is.

多層膜フィルムによる上述の光学的効果を得るには、多層膜フィルムの厚さは０．１ｍｍ程度で充分であり、あまり厚くしても効果は変わらない上にコストが高くなるという欠点がある。一方で、このように薄い多層膜フィルムだけでは、装飾材としての形状維持が難しいという問題もある。 In order to obtain the above-mentioned optical effect by the multilayer film, it is sufficient that the thickness of the multilayer film is about 0.1 mm, and even if it is too thick, the effect is not changed and the cost is increased. On the other hand, there is a problem that it is difficult to maintain the shape as a decorative material only with such a thin multilayer film.

従って、請求項２記載のように、請求項１記載の装飾材において、前記多層膜フィルムの片面又は両面に形状安定用の合成樹脂フィルムが積層されている構成とするのが望ましい。具体的には、比較的厚い（例えば０．２〜１．０ｍｍ程度）の合成樹脂フィルムを片面又は両面に積層して、積層後の板厚を０．３〜２．０ｍｍ程度にする。こうすれば装飾材としての形状を確実に維持できる。 Therefore, as described in claim 2, in the decorative material according to claim 1, it is desirable that a synthetic resin film for stabilizing the shape is laminated on one side or both sides of the multilayer film. Specifically, a relatively thick synthetic resin film (for example, about 0.2 to 1.0 mm) is laminated on one side or both sides, and the thickness after lamination is about 0.3 to 2.0 mm. In this way, the shape as a decorative material can be reliably maintained.

形状安定用の合成樹脂フィルムの材質（強度）にもよるが、積層後の板厚が０．２ｍｍ以下であると形状維持が難しいので０．３ｍｍ以上が望ましい。
また、形状安定用の合成樹脂フィルムの板厚はもっと大きくてもよいし、積層後の板厚ももっと大きくてもよいが、あまり厚くしても形状維持の効果は変わらないし、成形作業（例えば真空成形、圧空成形、真空圧空成形）をし難くなるおそれがある。従って、合成樹脂フィルムを片面又は両面に積層した後の板厚を２．０ｍｍ程度（それ以下）にするのが望ましい。 Although depending on the material (strength) of the synthetic resin film for stabilizing the shape, if the plate thickness after lamination is 0.2 mm or less, it is difficult to maintain the shape, so 0.3 mm or more is desirable.
Further, the thickness of the synthetic resin film for stabilizing the shape may be larger, and the thickness after lamination may be larger, but the effect of maintaining the shape does not change even if it is too thick, and the molding operation (for example, There is a risk that it may be difficult to perform vacuum forming, pressure forming, or vacuum / pressure forming. Therefore, it is desirable that the plate thickness after laminating the synthetic resin film on one side or both sides is about 2.0 mm (or less).

形状安定用の合成樹脂フィルムの材質は、ＰＥＴでもよいが、それよりも強度がある他の材質を使用して全体の板厚を抑制するのが好ましい。すなわち請求項５の構成とするのが好ましい。 The material of the synthetic resin film for stabilizing the shape may be PET, but it is preferable to suppress the overall thickness by using another material having strength higher than that. That is, it is preferable to have the configuration of claim 5.

強度が大きい材質として例えばポリカーボネートが推奨されるが、他の合成樹脂材料を使用できる。ただし、透明であることが望ましく、両面に積層する場合は透明であることが必須である。なお、片面を透明、他面を不透明とすることはできる。 For example, polycarbonate is recommended as a material having high strength, but other synthetic resin materials can be used. However, it is desirable to be transparent, and when laminating on both sides, it is essential to be transparent. One side can be transparent and the other side can be opaque.

本発明の装飾材は反射光を利用するが、透明であるから背後からの透過光をも利用できる。このため、請求項３記載のように、該装飾材の背面に有色の背後材を配せば、その背後材による反射光が重畳して装飾材の色合いに変化を与える。例えば赤色の背後材を用いれば、装飾材としての発光色を赤系に偏らせることができる。また黒、濃緑、濃茶等の暗い色の背後材を用いれば、透過光の影響を排除して（又は少なくして）反射光を強調できる。 The decorative material of the present invention uses reflected light, but since it is transparent, it can also use transmitted light from behind. For this reason, as described in claim 3, if a colored back material is disposed on the back surface of the decorative material, the reflected light from the back material is superimposed to change the color of the decorative material. For example, if a red backing material is used, the luminescent color as a decoration material can be biased to red. Further, when a dark backing material such as black, dark green, or dark brown is used, the reflected light can be enhanced by eliminating (or reducing) the influence of transmitted light.
