Abstract

PROBLEM TO BE SOLVED: To provide a decorative film and a decorative housing having a color and a pattern giving a feel of depth and deepness.SOLUTION: The decorative housing has a laminate 1 consisting of two or more transparent or translucent thin films 1-1 to 1-n laminated, on the surface of its body 4. The refractive indices of the thin films 1-1 to 1-n vertically adjacent to each other are mutually different, and the refractive indices or thicknesses of the thin films 1-1 to 1-n constituting the laminate 1 are selected randomly. The amounts of reflections from individual thin films 1-1 to 1-n change randomly even when the viewing angle changes slightly, imparting depth and deepness to the color and pattern on the surface.

Description

本発明は携帯電話及びパーソナルコンピュータ等の電子機器の筐体表面に設けられて加飾する加飾フィルム、かかる加飾フィルムにより加飾された加飾筐体、及びかかる加飾筐体を有する電子機器に関し、とくに、色彩及び絵柄に深みと奥行きとを感じさせる加飾フィルム、加飾筐体及び電子機器に関する。   The present invention provides a decorative film that is provided and decorated on the surface of a casing of an electronic device such as a mobile phone and a personal computer, a decorative casing that is decorated with such a decorative film, and an electronic device having such a decorative casing. In particular, the present invention relates to a decorative film, a decorative housing, and an electronic device that make a color and a pattern feel depth and depth.

電子機器の筐体、例えば携帯電話やパーソナルコンピュータの筐体には、剛性及び量産性に加えて、優れた意匠性が要求される。このため、筐体表面に光沢、色彩又は絵柄を付与する加飾処理が施される。   In addition to rigidity and mass productivity, an excellent design is required for a casing of an electronic device, for example, a casing of a mobile phone or a personal computer. For this reason, the decoration process which provides glossiness, a color, or a pattern to a housing | casing surface is given.

加飾は、通常は塗装によりなされる。しかし、塗装は筐体表面を広範に単一色に彩色するには適するものの、絵柄を描くのは難しい。とくに、凹凸を有する筐体の表面に、塗装により絵柄を形成することは容易ではない。また、塗装は溶剤を用いるために、VOC(揮発性有機化合物)が排出され環境負荷が大きい。   Decoration is usually done by painting. However, although painting is suitable for coloring the surface of the housing widely into a single color, it is difficult to draw a picture. In particular, it is not easy to form a pattern by painting on the surface of a housing having irregularities. In addition, since a solvent is used for painting, VOC (volatile organic compound) is discharged and the environmental load is large.

加飾フィルムはベースフィルム上に透明又は半透明の薄膜と、絵柄が印刷された薄膜とを複数層積層したフィルムからなり、この加飾フィルムで筐体表面を被覆することにより、加飾筐体の表面に色彩と絵柄とを容易に付与することができる。さらに、この加飾方法は、溶剤を必要としないので環境負荷も少ない。   The decorative film consists of a film in which a transparent or semi-transparent thin film and a thin film on which a pattern is printed are laminated on a base film. By covering the surface of the casing with this decorative film, the decorative film A color and a pattern can be easily imparted to the surface. Furthermore, since this decorating method does not require a solvent, the environmental load is small.

しかし、加飾フィルムの色彩及び絵柄は、例えばシルク印刷やグラビア印刷のようなインクを用いた印刷により形成されるため、色彩及び絵柄が平坦でかつ光沢及び奥行きがなく深みが感じられない。   However, since the color and the pattern of the decorative film are formed by printing using ink such as silk printing or gravure printing, for example, the color and the pattern are flat, and neither gloss nor depth is felt.

屈折率の異なる2種の透明フィルムを多数層積層して、光干渉により虹彩色を呈する加飾フィルムが知られている(例えば特許文献1参照。)。また、真空蒸着を用いて筐体表面に、例えば金属酸化物からなる高屈折率層と、例えば金属又は金属フッ化物からなる低屈折率層とを交互に数層積層した筐体加飾用の光学薄膜積層体が知られている。この光学薄膜積層体は、各層内の光干渉により所望の色彩を呈する(例えば特許文献2参照。)。   There is known a decorative film in which a large number of two types of transparent films having different refractive indexes are laminated to exhibit an iris color by light interference (see, for example, Patent Document 1). Further, for vacuuming the case, the high-refractive-index layer made of, for example, metal oxide and the low-refractive-index layer made of, for example, metal or metal fluoride are alternately laminated on the surface of the case for decorating the case. Optical thin film laminates are known. This optical thin film laminate exhibits a desired color due to light interference in each layer (see, for example, Patent Document 2).

これらの加飾フィルム及び光学薄膜積層体では、干渉により所定の色彩を得ている。このため、各層の屈折率及び厚さは、所定の光学的厚さになるように定められる。   In these decorative films and optical thin film laminates, a predetermined color is obtained by interference. For this reason, the refractive index and thickness of each layer are determined so as to have a predetermined optical thickness.

上述したように、塗装による加飾では、色彩及び絵柄がインクにより彩色された平坦な図形となるため、光沢及び奥行きのある深みを感じさせる装飾を施すことは難しい。   As described above, in the decoration by painting, since the color and the pattern become a flat figure colored with ink, it is difficult to apply a decoration that gives a glossy and deep depth.

また、従来のフィルム又は蒸着膜を積層した加飾フィルム及び光学薄膜積層体では、所望の干渉色を呈するように、各積層の膜厚及び屈折率を所定の厚さに選定する必要がある。このため、見る方向又は角度が変わっても色彩及び絵柄の変化が滑らかで、色彩又は絵柄に奥行と深みとを感じさせない。   Moreover, in the decorative film and optical thin film laminated body which laminated | stacked the conventional film or the vapor deposition film, it is necessary to select the film thickness and refractive index of each lamination | stacking to predetermined thickness so that a desired interference color may be exhibited. For this reason, even if the viewing direction or angle changes, the color and the pattern change smoothly, and the color or the pattern does not feel the depth and depth.

本発明は、色彩又は絵柄に深みと奥行きとを感じさせる意匠が施された加飾フィルム及び加飾筐体の提供を目的とする。   An object of the present invention is to provide a decorative film and a decorative housing in which a design that makes a color or a pattern feel depth and depth is applied.

上記課題を解決するための本発明の加飾筐体は、筐体本体の表面に、透明又は半透明の複数の薄膜が積層された積層体を有し、上下に隣接する前記薄膜の屈折率が互いに異なり、かつ、前記積層体を構成する各前記薄膜の屈折率又は厚さがランダムに選択されていることを特徴として構成する。   The decorative casing of the present invention for solving the above problems has a laminate in which a plurality of transparent or semi-transparent thin films are laminated on the surface of the casing body, and the refractive index of the thin films adjacent to each other in the vertical direction. Are different from each other, and the refractive index or the thickness of each of the thin films constituting the laminated body is selected at random.

本発明の加飾筐体では、積層体を構成する各薄膜の屈折率又は厚さがランダムに選択されており、薄膜ごとに反射率及び屈折角がランダムに変化する。そのため、筐体表面を見る角度又は方向が変化すると、各薄膜からの反射強度が積層体の深さにより異なる変化をし、その変化がランダムに見えるので、色彩及び模様に奥行きと深みとを感じさせる。   In the decorative housing of the present invention, the refractive index or thickness of each thin film constituting the laminate is selected at random, and the reflectance and the refraction angle change randomly for each thin film. Therefore, when the angle or direction of viewing the housing surface changes, the reflection intensity from each thin film changes depending on the depth of the laminate, and the change looks random, so the color and pattern feel the depth and depth. Let

本発明の第1実施形態は、積層体を構成する薄膜の屈折率がランダムに選択された加飾筐体に関する。   1st Embodiment of this invention is related with the decorating housing | casing in which the refractive index of the thin film which comprises a laminated body was selected at random.

図1は本発明の第1実施形態の加飾筐体断面図であり、筐体本体1の表面に設けられた加飾フィルム10の積層構造を表している。   FIG. 1 is a cross-sectional view of a decorative casing according to the first embodiment of the present invention, and shows a laminated structure of a decorative film 10 provided on the surface of the casing main body 1.

図1を参照して、本第1実施形態では、PC−ABS樹脂(ポリカーボネイト−ABS樹脂)を基材とするノートパソコンの筐体本体4の表面に、加飾フィルム10が密着して設けられている。この筐体本体4表面に加飾フィルム10が設けられた加飾筐体20は、例えば、予め作製された加飾フィルム10をセットした金型に樹脂を射出成形するフィルムインサートにより製造することができる。あるいは、予め加飾フィルム10と筐体本体1を作製しておき、真空圧空成形により筐体本体1表面に加飾フィルム10を密着させ被覆することで製造することもできる。なお、筐体本体1は他の樹脂、たとえばフォイバー強化樹脂で形成されてもよく、また、樹脂以外の材料、例えば金属材料で形成されてもよい。   Referring to FIG. 1, in the first embodiment, a decorative film 10 is provided in close contact with the surface of a casing body 4 of a notebook computer using PC-ABS resin (polycarbonate-ABS resin) as a base material. ing. The decorative casing 20 provided with the decorative film 10 on the surface of the casing main body 4 can be manufactured, for example, by a film insert that injection-molds a resin in a mold in which the decorative film 10 prepared in advance is set. it can. Alternatively, the decorative film 10 and the housing main body 1 can be prepared in advance, and the decorative film 10 can be manufactured in close contact with the surface of the housing main body 1 by vacuum / pressure forming. The housing body 1 may be formed of another resin, for example, a fiber reinforced resin, or may be formed of a material other than the resin, for example, a metal material.

本第1実施形態の加飾フィルム10は、透明または不透明の樹脂フィルムからなるn層の薄膜1−1〜1−nが積層された積層体1を有する。積層体1は、積層体1の最下層の薄膜1−nをベースフィルムとして、このベースフィルム1−n上にn−1層の薄膜1−1〜1−n−1が積層されている。ベースフィルム1−nの下面には、鏡面層2及び接着層3がこの順に設けられる。なお、ベースフィルムは積層体1の最下面を構成する薄膜1−nであり、従って、ベースフィルム1−nは、薄膜1−1〜1−n−1と共に、n層の薄膜1−1〜1−nからなる積層体1を構成している。   The decorative film 10 of the first embodiment includes a laminate 1 in which n layers of thin films 1-1 to 1-n made of a transparent or opaque resin film are laminated. In the laminate 1, n-1 thin films 1-1 to 1-n-1 are laminated on the base film 1 -n using the lowermost thin film 1 -n of the laminate 1 as a base film. On the lower surface of the base film 1-n, the mirror surface layer 2 and the adhesive layer 3 are provided in this order. The base film is a thin film 1-n constituting the lowermost surface of the laminate 1, and thus the base film 1-n is formed of n thin films 1-1 to 1-1 together with the thin films 1-1 to 1-n-1. The laminated body 1 which consists of 1-n is comprised.

ベースフィルム1−n(薄膜1−n)を含めて薄膜1−1〜1−nは、PET(ポリエチレンテレフタレート)樹脂、PC(ポリカーボネイト)樹脂及びPMMA(ポリメタクリル酸メチル)樹脂又はこれらのポリマーアロイからなり、それぞれの薄膜1−1〜1−nごとに固有の屈折率を有するように樹脂の種類又はポリマーアロイの組成が調整されている。なお、ベースフィルム1−nは、屈折率にこだわらず機械的強度及び加工性に優れた樹脂、例えばPET樹脂を用いることが好ましい。また、薄膜1−1〜1−nを構成する樹脂フィルムは、これらの樹脂に限られず、例えは屈折率1.4近傍の小さな屈折率の樹脂と、屈折率3近傍の大きな屈折率の樹脂とを含む2種以上の樹脂及びこれらのポリマーアロイを用いることが、屈折率の違いを広範に分散させるために好ましい。もちろん、単体の樹脂のみで屈折率を広範に分散することができるならは、ポリマーアロイを用いずに単体の樹脂で個性してもよい。   The thin films 1-1 to 1-n including the base film 1-n (thin film 1-n) are PET (polyethylene terephthalate) resin, PC (polycarbonate) resin, PMMA (polymethyl methacrylate) resin, or a polymer alloy thereof. The type of resin or the composition of the polymer alloy is adjusted so that each thin film 1-1 to 1-n has a specific refractive index. For the base film 1-n, it is preferable to use a resin excellent in mechanical strength and processability, for example, a PET resin regardless of the refractive index. The resin films constituting the thin films 1-1 to 1-n are not limited to these resins. For example, a resin having a small refractive index near a refractive index of 1.4 and a resin having a large refractive index near a refractive index of 3 are used. It is preferable to use two or more kinds of resins containing these and these polymer alloys in order to widely disperse the difference in refractive index. Of course, if the refractive index can be dispersed widely only with a single resin, it may be individualized with a single resin without using a polymer alloy.

各薄膜1−1〜1−nの屈折率は、積層方向にランダムに分布するように配置される。この配置方法として、例えば、使用する樹脂フィルムが有する最大屈折率と最小屈折率との間を、N個の屈折率に等分する。そして、等分されたN個の屈折率をランダムに並べ替え、この並べ替えた屈折率を、積層体1の最上面の薄膜1−1から最下面から一つ上の薄膜1−n−1に至るまで順に付与する。次いで、各薄膜が付与された屈折率を有するポリマーアロイ又は樹脂を選択し、これらのポリマーアロイ又は樹脂からなるフィルムにより薄膜1−1〜1−n−1を構成する。これにより、各薄膜1−1〜1−n−1の屈折率がランダムに選択された、即ち、隣接する薄膜1−1〜1−n−1の屈折率がランダムに変化する積層体1が製造される。   The refractive indexes of the thin films 1-1 to 1-n are arranged so as to be randomly distributed in the stacking direction. As this arrangement method, for example, a portion between the maximum refractive index and the minimum refractive index of the resin film to be used is equally divided into N refractive indexes. Then, the equally divided N refractive indexes are rearranged at random, and this rearranged refractive index is changed from the thin film 1-1 on the top surface of the laminate 1 to the thin film 1-n-1 one layer above the lowermost surface. It gives in order until it reaches. Next, a polymer alloy or resin having a refractive index to which each thin film is applied is selected, and the thin films 1-1 to 1-n-1 are constituted by films made of these polymer alloys or resins. Thereby, the refractive index of each thin film 1-1 to 1-n-1 was selected at random, that is, the laminated body 1 in which the refractive indexes of the adjacent thin films 1-1 to 1-n-1 changed randomly. Manufactured.

色彩に深みと奥行きを付与するためには、積層体1の層数nを多くすることが好ましく、積層体1の層数nを100層以上、より好ましくは200層以上とすることが望ましい。しかし、積層数が多過ぎると積層体1が厚くなり加工性が劣化する他、光の減衰が大きくなるため層数の増加が加飾効果に寄与しなくなる。このため、例えば積層体1の層数nを400層以下とすることが好ましい。もちろん、積層体1の光透過率が高ければ、より多層の積層体1を用いてより大きな深みと奥行きを付与することができる。なお、本第1実施形態では、各薄膜1−1〜1−nの厚さは、互いに異なっていてもよく、また同一であってもよい。   In order to add depth and depth to the color, it is preferable to increase the number n of layers of the laminate 1, and it is desirable that the number n of layers 1 is 100 or more, more preferably 200 or more. However, if the number of layers is too large, the laminate 1 becomes thick and the workability deteriorates, and the attenuation of light increases so that the increase in the number of layers does not contribute to the decoration effect. For this reason, it is preferable that the number of layers n of the laminated body 1 is 400 or less, for example. Of course, if the light transmittance of the laminated body 1 is high, a larger depth and depth can be provided by using the multilayered body 1 having a higher number of layers. In the first embodiment, the thicknesses of the thin films 1-1 to 1-n may be different from each other or the same.

積層体1の厚さは、加飾フィルム10の製造の容易性及び筐体への被覆性の観点から、300μm以下とすることが好ましい。本第1実施形態では、積層体1の厚さを200μmとした。このように、厚さ200μmの積層体1に200層以上の薄膜を積層するためには、薄膜1−1〜1−nの厚さを1μm〜0.1μmとすることが望ましい。なお、本発明では特定の薄膜が所望の干渉色を呈する必要はないので、厚さ及び屈折率を精密に制御する必要はない。   The thickness of the laminated body 1 is preferably 300 μm or less from the viewpoint of ease of manufacturing the decorative film 10 and coverage with respect to the housing. In the first embodiment, the thickness of the laminate 1 is 200 μm. Thus, in order to laminate 200 or more thin films on the laminate 1 having a thickness of 200 μm, the thickness of the thin films 1-1 to 1-n is preferably 1 μm to 0.1 μm. In the present invention, since a specific thin film does not need to exhibit a desired interference color, it is not necessary to precisely control the thickness and refractive index.

積層体1の下面(即ち、ベースフィルム1−nの下面)に、鏡面層2が形成されている。鏡面層2は、鏡面層2上面での反射率が高い材料が好ましく、例えば金属蒸着膜が用いられる。さらに、鏡面層2の下面に、接着層3が設けられる。接着層3は、フィルムインサートにより筐体本体4を形成する際、筐体本体4の表面に積層体1及び鏡面層を接着するために設けられる。同様に、、真空圧空成形により成形された筐体本体4の表面に積層体1及び鏡面層2を被覆させる際、筐体本体4の表面に積層体1及び鏡面層2を密着させるために設けられる。   A mirror surface layer 2 is formed on the lower surface of the laminate 1 (that is, the lower surface of the base film 1-n). The mirror surface layer 2 is preferably made of a material having a high reflectance on the upper surface of the mirror surface layer 2, and for example, a metal vapor deposition film is used. Further, an adhesive layer 3 is provided on the lower surface of the mirror surface layer 2. The adhesive layer 3 is provided to adhere the laminate 1 and the mirror layer to the surface of the housing body 4 when the housing body 4 is formed by a film insert. Similarly, when the laminate 1 and the mirror surface layer 2 are coated on the surface of the casing body 4 formed by vacuum / pressure forming, the laminate 1 and the mirror layer 2 are provided in close contact with the surface of the casing body 4. It is done.

上述した加飾筐体20は、以下のようにして製造することができる。   The decorative casing 20 described above can be manufactured as follows.

まず、ベースフィルム1−nの20〜30倍の厚さを有する樹脂フィルム上に、同じく各薄膜1−1〜1−n−1の20〜30倍の厚さを有する樹脂フィルムを積層した積層樹脂フィルムを形成する。このとき、樹脂フィルムの厚さの比及び屈折率は、薄膜1−1〜1−nの厚さの比及び屈折率と等しくする。   First, a laminate in which a resin film having a thickness 20 to 30 times that of each thin film 1-1 to 1-n-1 is laminated on a resin film having a thickness 20 to 30 times that of the base film 1-n. A resin film is formed. At this time, the thickness ratio and refractive index of the resin film are made equal to the thickness ratio and refractive index of the thin films 1-1 to 1-n.

次いで、この積層樹脂フィルムを厚さが20〜30分の1になるまで伸延して、ラミネート成形された薄膜1−1〜1−nからなる積層体1を形成する。ついで、積層体1の下面に鏡面層2及び接着層3を順次形成して、加飾フィルム10が製造される。   Next, the laminated resin film is stretched until the thickness becomes 1/30 to 1/30 to form a laminate 1 made of laminated thin films 1-1 to 1-n. Next, the mirror layer 2 and the adhesive layer 3 are sequentially formed on the lower surface of the laminate 1 to produce the decorative film 10.

次いで、加飾フィルム10を金型にセットして樹脂を射出形成するフィルムインサートを用いて、表面に加飾フィルム10が接着した加飾筐体20を製造する。ほかに、真空空圧成形により、予め射出成形された筐体本体4の表面を被覆するように加飾フィルム10を接着することで、加飾筐体20を製造してもよい。   Next, the decorative casing 20 having the decorative film 10 bonded to the surface is manufactured using a film insert in which the decorative film 10 is set in a mold and resin is injection-formed. In addition, the decorative casing 20 may be manufactured by adhering the decorative film 10 so as to cover the surface of the casing main body 4 that has been injection molded in advance by vacuum pneumatic molding.

次に、本第1実施形態の加飾筐体の意匠について説明する。   Next, the design of the decorative housing of the first embodiment will be described.

図1を参照して、斜め上面から積層体1表面に入射した入射光11は、積層体1を構成する薄膜1−1〜1−n中を屈折して進行方向を変えながら進行する。そして、その進行する入射光11の一部は、各薄膜1−1〜1−nの界面(最上層及び最下層の薄膜1−1、1−nではそれぞれ上面及び下面)で反射される。この各薄膜1−1〜1−nで反射された光は合波して、積層体1からの反射光12として出射し視認される。このように、視認される反射光12は、入射地点が異なる入射光11−0〜11−nが、それぞれ薄膜1−0〜1−nの上面及び薄膜1−nの下面で反射(多重反射を含む)された反射光が合波されて形成される。なお、図1では、入射光11−nの積層体1中の光路を省略して図示している。   Referring to FIG. 1, incident light 11 incident on the surface of laminated body 1 from an oblique upper surface travels while being refracted in thin films 1-1 to 1-n constituting laminated body 1 and changing the traveling direction. A part of the traveling incident light 11 is reflected at the interfaces of the thin films 1-1 to 1-n (upper and lower surfaces of the uppermost and lowermost thin films 1-1 and 1-n, respectively). The light reflected by each of the thin films 1-1 to 1-n is combined and emitted as reflected light 12 from the laminated body 1 and is visually recognized. In this way, the reflected light 12 that is visually recognized is reflected by the incident light 11-0 to 11-n at different incident points on the upper surface of the thin film 1-0 to 1-n and the lower surface of the thin film 1-n (multiple reflection). Are formed by combining the reflected light. In FIG. 1, the optical path of the incident light 11-n in the stacked body 1 is omitted.

n層の各薄膜1−0〜1−n上面の反射率は、その上面を挟む物質の屈折率の差及びその上面への入射角に依存する。本第1実施形態では各薄膜1−1〜1−nの屈折率がランダムに選択されている。そのため、同一方向から入射光11が入射しても、各薄膜1−0〜1−nでの屈折角が違がうため、各薄膜1−0〜1−n上面への入射角が、各薄膜1−0〜1−nごとにランダムに変化する。また、各薄膜1−0〜1−nの上面を挟む上下の薄膜の屈折率が、各薄膜1−0〜1−nの上面ごとにランダムに変化する。このため、各薄膜1−0〜1−nの上面の反射率は、各薄膜1−0〜1−nごとに、言い換えれば深さ方向にランダムに異なるものとなる。   The reflectance of the upper surface of each of the n-layered thin films 1-0 to 1-n depends on the difference in refractive index between the materials sandwiching the upper surface and the incident angle on the upper surface. In the first embodiment, the refractive indexes of the thin films 1-1 to 1-n are selected at random. Therefore, even if the incident light 11 is incident from the same direction, the refraction angles of the thin films 1-0 to 1-n are different. It changes randomly for each thin film 1-0 to 1-n. In addition, the refractive index of the upper and lower thin films sandwiching the upper surface of each thin film 1-0 to 1-n changes randomly for each upper surface of each thin film 1-0 to 1-n. For this reason, the reflectance of the upper surface of each thin film 1-0 to 1-n is randomly different in the depth direction for each thin film 1-0 to 1-n.

さらに、各薄膜1−0〜1−n上面の反射率は、積層体1表面に入射する入射光1の入射角(即ち反射光12の反射角)の僅かな変化により大きく変化する。このため、各薄膜1−0〜1−n上面からの反射光の光量も見る角度により大きく変化する。その結果、見る角度の僅かな変動が各薄膜1−0〜1−n上面の反射光量のランダムな変動を引き起こし、見る者に、多層の反射面が上下にランダムに飛び移るような感じを与えるので、積層体1中の色彩に奥行きを感じさせる。また、各薄膜1−0〜1−n上面からの反射光のスペクトルも入射角の僅かな変動により大きく変化する。このため、見る角度の僅かな変化が、反射光12のスペクトルのランダムな複雑な変化を引き起こすので、奥行き感とあいまって見る者に色彩の深みを感じさせる。   Further, the reflectance of the upper surface of each thin film 1-0 to 1-n varies greatly due to a slight change in the incident angle of incident light 1 (that is, the reflection angle of reflected light 12) incident on the surface of the laminate 1. For this reason, the amount of reflected light from the upper surface of each thin film 1-0 to 1-n also varies greatly depending on the viewing angle. As a result, a slight change in the viewing angle causes a random change in the amount of reflected light on the upper surface of each thin film 1-0 to 1-n, giving the viewer the feeling that the multilayer reflective surface jumps up and down randomly. Therefore, the color in the laminate 1 is made to feel depth. Further, the spectrum of the reflected light from the upper surface of each thin film 1-0 to 1-n also changes greatly due to slight fluctuations in the incident angle. For this reason, a slight change in the viewing angle causes a random and complex change in the spectrum of the reflected light 12, and this makes the viewer feel the color depth combined with the sense of depth.

第1実施形態の薄膜1−1〜1−nは、無色透明であっても、また透明色を有するものでもよい。薄膜1−1〜1−nの一つ又は複数を着色することで、反射光量のみならず色調も飛び移るように変化する感じを与え、色彩の深みをより感じさせる。   The thin films 1-1 to 1-n of the first embodiment may be colorless and transparent or may have a transparent color. By coloring one or more of the thin films 1-1 to 1-n, a feeling of changing not only the amount of reflected light but also the color tone is given, and the depth of color is more felt.

さらに、薄膜1−1〜1−nの光透過率を、例えばランダムになるように設定してもよい。薄膜1−1〜1−nの光透過率が異なると、反射光の光量の変動がより大きくなるので、奥行きをより強く感じさせることができる。また、薄膜1−1〜1−n中に屈折率の異なる物質からなる微粒子あるいは反射率の高い微粒子例えば金属フレークを混入してもよい。これらの微粒子の混入により、乱反射を多くして光沢と色彩の深みを増すことができる。   Further, the light transmittance of the thin films 1-1 to 1-n may be set to be random, for example. When the light transmittances of the thin films 1-1 to 1-n are different, the variation in the amount of reflected light becomes larger, so that the depth can be felt more strongly. Further, fine particles made of substances having different refractive indexes or fine particles having high reflectivity, for example, metal flakes may be mixed in the thin films 1-1 to 1-n. By mixing these fine particles, irregular reflection can be increased and the depth of gloss and color can be increased.

本第1実施形態では、さらに積層体1下面に鏡面層2が設けられる。鏡面層2は、薄膜1−n(ベースフィルム)の下面を高反射率の界面とするために設けられる。このように薄膜1−nの下面を高反射率とすることで、金属表面のようなギラポラとした輝く感じを付与することができる。なお、必要がなければ、鏡面層2を設けなくてもよい。   In the first embodiment, the mirror layer 2 is further provided on the lower surface of the laminate 1. The mirror surface layer 2 is provided so that the lower surface of the thin film 1-n (base film) serves as a highly reflective interface. Thus, by making the lower surface of the thin film 1-n have a high reflectivity, it is possible to give a glittering feeling like a metal surface. If not necessary, the mirror layer 2 may not be provided.

本発明の第2実施形態は、積層体を構成する薄膜の厚さがランダムに選択された加飾筐体に関する。   2nd Embodiment of this invention is related with the decorating housing | casing in which the thickness of the thin film which comprises a laminated body was selected at random.

図2は本発明の第2実施形態の加飾筐体断面図であり、筐体本体1の表面に設けられた加飾フィルム11の積層構造を表している。   FIG. 2 is a cross-sectional view of a decorative casing according to the second embodiment of the present invention, and shows a laminated structure of a decorative film 11 provided on the surface of the casing main body 1.

図2を参照して、本第2実施形態の加飾筐体21は、薄膜1−1〜1−nの屈折率及び厚さを除き他は第1実施形態の加飾筐体20と同一である。従って、重複を避けるために、以下、この相違点を主として説明する。   With reference to FIG. 2, the decorative housing 21 of the second embodiment is the same as the decorative housing 20 of the first embodiment except for the refractive index and thickness of the thin films 1-1 to 1-n. It is. Therefore, in order to avoid duplication, this difference will be mainly described below.

本第2実施形態では、積層体1を構成する薄膜1−1〜1−nは、PET樹脂、PC樹脂及びPMMA樹脂のいずれからからなる。従って、積層体1は3つの互いに異なる屈折率を有する薄膜1−1〜1−nから構成される。なお、積層体1を、屈折率の異なる3以上のその他の種類の樹脂フィルムからなる薄膜1−1〜1−nで構成してもよい。   In the second embodiment, the thin films 1-1 to 1-n constituting the laminated body 1 are made of any of PET resin, PC resin, and PMMA resin. Therefore, the laminate 1 is composed of three thin films 1-1 to 1-n having different refractive indexes. In addition, you may comprise the laminated body 1 with the thin films 1-1 to 1-n which consist of 3 or more types of other resin films from which a refractive index differs.

各薄膜1−1〜1−nの厚さは、ランダムになるように選択されている。このようなランダムな厚さの分布は、たとえば、最大厚さ1μm〜最小厚さ0.1μmの範囲に分散する厚さを作成し、乱数の順に従って作成された厚さを薄膜1−1から薄膜1−nの順に割り振ることにより作成することができる。もちろん、各薄膜1−1〜1−nごとに直接ランダムな厚さを割り付けることもできる。   The thickness of each thin film 1-1 to 1-n is selected to be random. Such a random thickness distribution creates, for example, a thickness dispersed in a range of a maximum thickness of 1 μm to a minimum thickness of 0.1 μm, and the thicknesses generated in the order of random numbers from the thin film 1-1. They can be created by allocating in order of thin films 1-n. Of course, a random thickness can be directly assigned to each thin film 1-1 to 1-n.

かかる積層体1は、割り振られた厚さの比が等しいn枚の樹脂フィルムを積層し、伸延するラミネート加工により形成することがてきる。この積層体1下面に鏡面層2を蒸着し、さらに接着層3を形成して本第2実施形態の加飾フィルム11が製造される。   Such a laminated body 1 can be formed by laminating by laminating and extending n resin films having equal thickness ratios. The mirror surface layer 2 is vapor-deposited on the lower surface of the laminate 1, and the adhesive layer 3 is further formed to produce the decorative film 11 of the second embodiment.

本第2実施形態では、互いに隣接する薄膜1−i、1−i+1(i=1,2,・・・、n−1)の屈折率が異なるように樹脂フィルムが選択され、かつその厚さがランダムに選択される。このため、各薄膜1−1〜1−nの上面で反射される反射光の強度が見る角度によりランダムに変化する。従って、第1実施形態と同様に、奥行きと深みのある色彩を呈する。   In the second embodiment, the resin film is selected so that the refractive indexes of the thin films 1-i, 1-i + 1 (i = 1, 2,..., N-1) adjacent to each other are different, and the thickness thereof. Are randomly selected. For this reason, the intensity of the reflected light reflected from the upper surface of each thin film 1-1 to 1-n changes randomly depending on the viewing angle. Therefore, similar to the first embodiment, it has colors with depth and depth.

本第2実施形態の薄膜1−1〜1−nの屈折率を、第1実施形態と同様にランダムに選択することもできる。これにより、屈折率のランダム分布と膜厚のランダム分布との両者のランダム性が相まって、さらに複雑かつ意外性の高い色彩の変化をもたらし、より深みと奥行きとを感じさせる色彩を呈することができる。さらに、第1実施形態と同様に、薄膜1−1〜1−nに色彩を付す、薄膜1−1〜1−nの光透過率をランダムに分布させる、あるいは薄膜1−1〜1−nにフレークを混入することで、第1実施形態と同様の意匠効果をさらに加味することもできる。   The refractive indexes of the thin films 1-1 to 1-n of the second embodiment can be selected at random as in the first embodiment. As a result, the randomness of the refractive index random distribution and the random distribution of the film thickness combine to bring about a more complicated and unexpected color change, and can present a color that makes you feel deeper and deeper. . Further, similarly to the first embodiment, the thin films 1-1 to 1-n are colored, the light transmittance of the thin films 1-1 to 1-n is randomly distributed, or the thin films 1-1 to 1-n. By adding flakes to the surface, the design effect similar to that of the first embodiment can be further added.

本発明の第3実施形態は、低反射の膜からなる絵柄を有する加飾筐体に関する。   3rd Embodiment of this invention is related with the decorating housing | casing which has the pattern which consists of a low reflection film | membrane.

図3は本発明の第3実施形態の加飾筐体断面図であり、筐体本体1の表面に設けられた絵柄を含む加飾フィルム12の積層構造を表している。   FIG. 3 is a cross-sectional view of the decorative housing according to the third embodiment of the present invention, and shows a laminated structure of the decorative film 12 including a pattern provided on the surface of the housing body 1.

図3を参照して、本第3実施形態の加飾筐体22は、積層体1を構成する各薄膜1−1〜1−nがランダムな厚さ及びランダムな屈折率を有し、かつ、絵柄5が積層体1内部の1層をなす薄膜1−iに形成されている。   With reference to FIG. 3, in the decorative housing 22 of the third embodiment, each of the thin films 1-1 to 1-n constituting the laminate 1 has a random thickness and a random refractive index, and The pattern 5 is formed on the thin film 1-i forming one layer inside the laminate 1.

絵柄5は、薄膜1−iを構成する樹脂フィルムにインクを用いた印刷、例えばシルク印刷又はグラビア印刷により、顔料を含む樹脂フィルムの領域からなる絵柄5を形成する。従って、絵柄5の外側に延在する樹脂フィルムには顔料は含まれない。なお、絵柄5は、積層体1の成形前に、シート状の樹脂フィルムの状態で印刷する。   The pattern 5 is formed of a resin film region containing a pigment by printing using ink on the resin film constituting the thin film 1-i, for example, silk printing or gravure printing. Accordingly, the resin film extending outside the pattern 5 does not contain a pigment. In addition, the pattern 5 is printed in the state of a sheet-like resin film before forming the laminate 1.

この絵柄5の下面、即ち薄膜1−iの下に接する薄膜1−i+1と絵柄5の界面における反射光が、薄膜1−iの絵柄5が形成されていない領域と薄膜1−i+1の界面における反射光より弱くなるように、絵柄の顔料が選択される。かかる反射光を弱くする顔料は、樹脂フィルムの屈折率を変えるもの、あるいは単に光吸収率を大きくして反射光の強度を減衰するカーブラックの様な黒色顔料がある。また、顔料は有彩色に限られず、無彩色でもよい。かかる絵柄5からの反射光は、絵柄5の外側の反射光より弱くなる。   Reflected light at the lower surface of the pattern 5, that is, at the interface between the thin film 1-i + 1 and the pattern 5 in contact with the thin film 1-i, is reflected at the interface between the thin film 1-i and the thin film 1-i + 1. The pattern pigment is selected so as to be weaker than the reflected light. Such pigments that weaken the reflected light include those that change the refractive index of the resin film, or black pigments such as Kerr black that simply increase the light absorption rate and attenuate the intensity of the reflected light. The pigment is not limited to a chromatic color and may be an achromatic color. The reflected light from the pattern 5 is weaker than the reflected light outside the pattern 5.

さらに、積層体1の下面(ベースフィルムとなる薄膜1−nの下面)に、鏡面層及び接着層3が設けられ、積層体1は筐体本体4の表面に接着層3を介して接着される。これは、第1及び第2実施形態と同様である。   Furthermore, a mirror surface layer and an adhesive layer 3 are provided on the lower surface of the laminate 1 (the lower surface of the thin film 1-n serving as a base film), and the laminate 1 is bonded to the surface of the housing body 4 via the adhesive layer 3. The This is the same as in the first and second embodiments.

本第3実施形態では、絵柄5の上方に屈折率及び厚さがランダムに選択された薄膜1−1〜1−i−−1が積層されているため、絵柄5から反射した光が見る角度により変化し、絵柄5に奥行き感とその色彩の深みを感じさせる。さらに、絵柄5からの反射が絵柄5の外側の反射より弱いので、見る者に絵柄5が沈み込む感じを与える。従って、奥行きが感じられ、印刷の絵柄のように平面的な感じを与えることがない。   In the third embodiment, since the thin films 1-1 to 1-i-1 whose refractive index and thickness are randomly selected are stacked above the pattern 5, the angle at which the light reflected from the pattern 5 is viewed The pattern 5 is made to feel the depth and the depth of its color. Furthermore, since the reflection from the pattern 5 is weaker than the reflection on the outside of the pattern 5, the viewer feels that the pattern 5 sinks. Therefore, the depth is felt, and a flat feeling like a printed pattern is not given.

本発明の第4実施形態は、第3実施形態の絵柄を絵柄の平面形状(絵柄パターン)を有するフィルムで形成した加飾筐体に関する。   4th Embodiment of this invention is related with the decorating housing | casing which formed the pattern of 3rd Embodiment with the film which has the planar shape (pattern pattern) of a pattern.

図4は本発明の第4実施形態の加飾筐体断面図であり、筐体本体の表面に設けられた絵柄を含む加飾フィルムの積層構造を表している。   FIG. 4 is a cross-sectional view of a decorative housing according to the fourth embodiment of the present invention, and shows a laminated structure of decorative films including a pattern provided on the surface of the housing main body.

Thickness. Further, a mirror surface layer 2 and an adhesive layer 3 are provided on the lower surface of the laminate 1.

本第4実施形態では、積層体1を構成する薄膜1−iと薄膜1−i+1との界面の一部に、絵図が描かれたフィルム状の絵柄5が埋設されている。この絵柄5を構成するフィルムは、絵柄5から反射される光量が絵柄5の外側の薄膜1−iと薄膜1−i+1との界面から反射される光量よりも弱くなるように、その屈折率又は光吸収率が選択されている。従って、第3実施形態と同様に、見る者に絵柄5が沈み込む感じを与える。   In the fourth embodiment, a film-like picture 5 on which a picture is drawn is embedded in a part of the interface between the thin film 1-i and the thin film 1-i + 1 constituting the laminated body 1. The film constituting the pattern 5 has its refractive index or the refractive index so that the amount of light reflected from the pattern 5 is weaker than the amount of light reflected from the interface between the thin film 1-i and the thin film 1-i + 1 outside the pattern 5. Light absorption is selected. Accordingly, as in the third embodiment, the viewer is given a feeling that the pattern 5 sinks.

この絵柄5は、所定の屈折率を有する着色された樹脂フィルムを型抜きして形成することがてきる。また、樹脂フィルムに所定の絵柄を印刷し、絵柄に沿って型抜きして形成してもよい。積層体1は、この型抜きされた樹脂フィルムを積層された樹脂フィルムの間に挟み、第1実施形態と同様に、ラミネート成形することで製造することができる。   The pattern 5 can be formed by punching out a colored resin film having a predetermined refractive index. Alternatively, a predetermined pattern may be printed on the resin film and die-cut along the pattern. The laminated body 1 can be manufactured by sandwiching the die-cut resin film between the laminated resin films and laminating like the first embodiment.

さらに、積層体1の下面に鏡面層2及び接着層3を形成し、第4実施形態の加飾フィルム13が製造される。この加飾フィルム13を、フィルムインサート又は真空空圧成形により筐体本体1表面に密着して設けることで、第4実施形態の加飾筐体23が製造される。   Furthermore, the mirror surface layer 2 and the adhesive layer 3 are formed on the lower surface of the laminate 1, and the decorative film 13 of the fourth embodiment is manufactured. The decorative casing 23 of the fourth embodiment is manufactured by providing the decorative film 13 in close contact with the surface of the casing body 1 by film insert or vacuum pneumatic molding.

本発明をノートパソコン等の電子機器の筐体の加飾に適用することで、深みと奥行きのある色調及び絵柄を有する装飾を筐体に施すことがてきる。   By applying the present invention to decoration of a casing of an electronic device such as a notebook personal computer, a decoration having a deep color tone and a pattern can be applied to the casing.
