Abstract

Description
本発明は、成形品及び表示装置に関する。
The present invention relates to a molded product and a display device.
成形品の表面には、意匠的な観点から金属調の加飾を施すことがある。金属調の加飾法としては、電解めっき法、真空蒸着法、ホットスタンピング法等が挙げられる。バンパー等の車両部品の加飾には、電解めっき法が広く用いられており、例えば、電解めっき法により、部品の表面にニッケル層を被覆し、さらにクロム層を被覆する方法が開示されている(例えば、特許文献1参照)。
The surface of the molded product may be decorated with a metallic tone from a design standpoint. Examples of the metallic decoration method include an electrolytic plating method, a vacuum deposition method, and a hot stamping method. Electrolytic plating methods are widely used for decorating vehicle parts such as bumpers. For example, a method is disclosed in which a nickel layer is coated on the surface of a component by electrolytic plating and further a chromium layer is coated. (For example, refer to Patent Document 1).
しかしながら、電解めっき法による金属調の加飾では、部品の重量が重くなるという問題がある。また、電気メッキ法、真空蒸着法及びホットスタンピング法は、いずれも特定の装置を必要とし、操作も煩雑である。
However, there is a problem that the weight of the parts becomes heavy in the decoration of the metal tone by the electrolytic plating method. In addition, the electroplating method, the vacuum deposition method, and the hot stamping method all require a specific apparatus and are complicated to operate.
そこで、銀鏡反応を利用して銀鏡層を形成する方法が挙げられる(例えば、特許文献2参照)。この方法では、基材の上に、下塗り層(アンダーコート層)、銀鏡層、及び上塗り層(トップコート層)を順次形成する。銀鏡反応を利用する方法は、簡易な装置によって加飾することができ、部品の重量増加も電解めっき法に比べて極めて低く抑えられる。
Therefore, there is a method of forming a silver mirror layer using a silver mirror reaction (see, for example, Patent Document 2). In this method, an undercoat layer (undercoat layer), a silver mirror layer, and an overcoat layer (topcoat layer) are sequentially formed on a substrate. The method using the silver mirror reaction can be decorated with a simple device, and the increase in the weight of the component can be suppressed to a very low level as compared with the electrolytic plating method.
しかしながら、銀鏡層を有する成形品は、多層構造であり、かつ視認側の最表面にトップコート層等の樹脂層が設けられているため、各層での反射光が互いに干渉しあうことで、成形品の表面に干渉縞による虹色が発現する場合がある。なお、電解めっきの場合、最表面に樹脂層を設けないため、このような干渉縞は生じず、銀鏡層を有する成形品で特有の課題である。この干渉縞により発現した虹色は色むらのように見えることもあり、好ましいものではない。また、車両用の成形品では、異物が入っているように見えることがあってはならない。
However, a molded article having a silver mirror layer has a multilayer structure, and a resin layer such as a topcoat layer is provided on the outermost surface on the viewing side. In some cases, rainbow colors due to interference fringes appear on the surface of the product. In the case of electrolytic plating, since no resin layer is provided on the outermost surface, such interference fringes are not generated, which is a problem specific to a molded product having a silver mirror layer. The rainbow color expressed by the interference fringes may appear as uneven color, which is not preferable. In addition, a molded article for a vehicle must not appear to contain foreign matter.
上記状況に鑑み、本発明は、銀鏡層を有し、表面での干渉縞による虹色の発現が抑制される成形品を提供することを目的とする。
In view of the above situation, an object of the present invention is to provide a molded article that has a silver mirror layer and suppresses the appearance of rainbow colors due to interference fringes on the surface.

Hereinafter, an example of the configuration of the molded product of the present disclosure will be described with reference to the drawings. However, the molded article of the present disclosure is not limited to these embodiments.
図1は、成形品100の概略断面図である。成形品100は、視認側(図中の矢印)から順に、基材10、アンダーコート層20、銀鏡層30、及びトップコート層40が設けられている。成形品100では、基材10が、視認側の外表面に設けられている。アンダーコート層20とトップコート層40は、樹脂層である。
FIG. 1 is a schematic sectional view of a molded product 100. The molded product 100 is provided with a base material 10, an undercoat layer 20, a silver mirror layer 30, and a topcoat layer 40 in order from the viewing side (arrow in the figure). In the molded product 100, the base material 10 is provided on the outer surface on the viewing side. The undercoat layer 20 and the topcoat layer 40 are resin layers.
成形品100では、アンダーコート層20に充填材が含有されている。アンダーコート層20に充填材が含有されることで、銀鏡層30による反射光が拡散し、光干渉が抑えられ、成形品100の表面での干渉縞による虹色の発現が抑制される。図示しないが、トップコート層40にも充填材が含有されていてもよい。
In the molded product 100, the undercoat layer 20 contains a filler. By containing the filler in the undercoat layer 20, the reflected light from the silver mirror layer 30 is diffused, optical interference is suppressed, and the appearance of rainbow colors due to interference fringes on the surface of the molded product 100 is suppressed. Although not shown, the top coat layer 40 may also contain a filler.
図2は、成形品110の概略断面図である。成形品110は、視認側から順に、トップコート層40、銀鏡層30、アンダーコート層20、及び基材10が設けられている。成形品110では、トップコート層40に充填材が含有されている。トップコート層40に充填材が含有されることで、銀鏡層30による反射光が拡散し、光干渉が抑えられ、成形品110の表面での干渉縞による虹色の発現が抑制される。図示しないが、アンダーコート層20にも充填材が含有されていてもよい。
FIG. 2 is a schematic sectional view of the molded product 110. The molded product 110 is provided with a top coat layer 40, a silver mirror layer 30, an undercoat layer 20, and a base material 10 in order from the viewing side. In the molded product 110, the top coat layer 40 contains a filler. By containing the filler in the top coat layer 40, the reflected light from the silver mirror layer 30 is diffused, light interference is suppressed, and the appearance of rainbow colors due to interference fringes on the surface of the molded product 110 is suppressed. Although not shown, the undercoat layer 20 may also contain a filler.
図1及び図2のように、充填材を含有する樹脂層が、銀鏡層30よりも視認側となるように、成形品を配置して使用することが好ましい。このような配置で使用することにより、光干渉が効果的に抑えられ、干渉縞による虹色の発現が効果的に抑制される。
As shown in FIGS. 1 and 2, it is preferable to use the molded product in such a manner that the resin layer containing the filler is closer to the viewing side than the silver mirror layer 30. By using in such an arrangement, optical interference is effectively suppressed, and the appearance of rainbow colors due to interference fringes is effectively suppressed.
なお、図1のように、最外層ではないアンダーコート層20に充填材を含有させた場合には、より光沢が増し、金属感が高くなる。
他方、図2のように、最外層であるトップコート層40に充填材を含有させた場合には、反射率が抑制され、落ち着いた雰囲気になり、また充填材の感触を得ることができる。さらに、傷付きが防止され、指紋の付着、べたつき等が抑えられる。 In addition, as shown in FIG. 1, when theundercoat layer 20 which is not the outermost layer contains a filler, the gloss is increased and the metal feeling is increased.
On the other hand, as shown in FIG. 2, when the filler is contained in thetop coat layer 40 which is the outermost layer, the reflectance is suppressed, the atmosphere becomes calm, and the feel of the filler can be obtained. In addition, scratching is prevented, and fingerprint adhesion and stickiness are suppressed.

図1の成形品100及び図2の成形品110は、光透過性を有する。よって、基材10、アンダーコート層20、銀鏡層30、及びトップコート層40は、それぞれ光透過性を有する。そのため、成形品100又は成形品110を介して、視認側とは反対側に置かれた物品を確認することができる。
The molded product 100 in FIG. 1 and the molded product 110 in FIG. 2 have light transmittance. Therefore, the base material 10, the undercoat layer 20, the silver mirror layer 30, and the topcoat layer 40 each have light transmittance. Therefore, an article placed on the side opposite to the viewing side can be confirmed via the molded product 100 or the molded product 110.
なお、本開示において、光透過性を有するとは、可視光の透過性(少なくとも波長400nmの可視光の透過性)が10%以上であることをいう。遮光画像層が設けられた成形品の場合には、非遮光部が光透過性を有すればよい。
In the present disclosure, having light transmittance means that the visible light transmittance (visible light transmittance of at least a wavelength of 400 nm) is 10% or more. In the case of a molded product provided with a light-shielding image layer, the non-light-shielding portion only needs to have light transmittance.
図3は、成形品120の概略断面図である。成形品120は、視認側から順に、基材10、アンダーコート層20、銀鏡層30、トップコート層40、及び遮光画像層50が設けられている。つまり、成形品120では、前述の成形品100において、視認側とは反対側の最外面に、遮光画像層50が配置されている。
FIG. 3 is a schematic sectional view of the molded product 120. The molded product 120 is provided with a base material 10, an undercoat layer 20, a silver mirror layer 30, a topcoat layer 40, and a light-shielding image layer 50 in order from the viewing side. That is, in the molded product 120, the light-shielding image layer 50 is disposed on the outermost surface on the side opposite to the viewing side in the molded product 100 described above.
成形品100に遮光画像層50を設け、視認側とは反対側に光源60を配置すると、光源60からの光は、遮光画像層50の遮光部では遮られるが、成形品100は光透過性を有するため非遮光部では透過する。よって、視認側から成形品120を観察すると、成形品120の基材10の表面に遮光画像層50の画像が表示される。
When the light-shielding image layer 50 is provided on the molded product 100 and the light source 60 is disposed on the side opposite to the viewing side, the light from the light source 60 is blocked by the light-shielding portion of the light-shielding image layer 50, but the molded product 100 is light transmissive. Therefore, the light is transmitted through the non-light shielding portion. Therefore, when the molded product 120 is observed from the viewing side, an image of the light shielding image layer 50 is displayed on the surface of the base material 10 of the molded product 120.
遮光画像層50は、銀鏡層30よりも視認側から遠い側に設けられていることが好ましく、例えば、図3における遮光画像層50の配置位置を、銀鏡層30とトップコート層40との間に変更してもよい。
また、図示しないが、視認側から遠い側に基材10が設けられる図2の成形品110に、遮光画像層50を設けてもよい。この場合も、遮光画像層50は、銀鏡層30よりも視認側から遠い側に設けることが好ましい。 The light-shieldingimage layer 50 is preferably provided on the side farther from the viewing side than the silver mirror layer 30. For example, the arrangement position of the light-shielding image layer 50 in FIG. 3 is between the silver mirror layer 30 and the top coat layer 40. You may change to
Although not shown, the light-shieldingimage layer 50 may be provided on the molded product 110 of FIG. 2 in which the base material 10 is provided on the side far from the viewing side. Also in this case, the light-shielding image layer 50 is preferably provided on the side farther from the viewing side than the silver mirror layer 30.
また、図示しないが、視認側から遠い側に基材10が設けられる図2の成形品110に、遮光画像層50を設けてもよい。この場合も、遮光画像層50は、銀鏡層30よりも視認側から遠い側に設けることが好ましい。 The light-shielding

なお、図1~図3では、アンダーコート層20及びトップコート層40は、それぞれ単層となっているが、二層以上の複数層としてもよい。例えば、図2において視認側の最外層であるトップコート層40が複数層であると、見た目に深みを増したものとなり、光沢感を出しやすい。
例えば、アンダーコート層20及びトップコート層40の少なくとも一方が二層以上の複数層である場合、これらのうちの少なくとも一層が充填材を含有していればよく、充填材を含有していないアンダーコート層20及びトップコート層40はクリア層であってもよい。 1 to 3, each of theundercoat layer 20 and the topcoat layer 40 is a single layer, but may be a plurality of layers of two or more layers. For example, when the top coat layer 40 that is the outermost layer on the viewing side in FIG. 2 is a plurality of layers, the depth is visually increased, and glossiness is easily obtained.
For example, when at least one of theundercoat layer 20 and the topcoat layer 40 is a plurality of two or more layers, it is sufficient that at least one of these layers contains a filler, and the undercoat does not contain a filler. The coat layer 20 and the top coat layer 40 may be clear layers.
例えば、アンダーコート層20及びトップコート層40の少なくとも一方が二層以上の複数層である場合、これらのうちの少なくとも一層が充填材を含有していればよく、充填材を含有していないアンダーコート層20及びトップコート層40はクリア層であってもよい。 1 to 3, each of the

また、図1~図3では、基材10は、成形品において一方の外表面に設けられているが、両面の外表面に設けられていてもよい。この場合には、基材10、アンダーコート層20、銀鏡層30、アンダーコート層20、基材10の順に設けられていることが好ましく、2つのアンダーコート層20のうち少なくとも一方に充填材が含有されていればよい。
