Description
本発明は、新規な意匠材及びそれを用いた構造体に関する。 The present invention relates to a novel design material and a structure using the same.
従来、紫外線を照射することにより発光する蛍光顔料を用いた装飾材が知られている。このような装飾材は、紫外線照射時と非照射時で異なる色相を示すため、様々な分野で高意匠性材料として用いられている。例えば、特許文献１には、透明または半透明のシート部材に、紫外線発光塗料で文字や図形を描いた装飾材が記載されており、この装飾材に紫外線を照射すると文字や図柄が発光するものである。
Conventionally, decorative materials using fluorescent pigments that emit light when irradiated with ultraviolet rays are known. Since such a decorative material exhibits different hues when irradiated with ultraviolet rays and when not irradiated, it is used as a highly designable material in various fields. For example,
また、紫外線光源と可視光光源を組み合わせ、それぞれの光源の照射パターンにより意匠性を高めることが検討されている。例えば、特許文献２には、透明基材上に蛍光表示部と普通表示部を部分的に有する表示板に、紫外線光源及び／又は可視光光源を照射する表示装置が記載されている。引用文献２では、紫外線光源と可視光光源の点灯／消灯により、蛍光表示部と普通表示部のどちらか一方を強調して見せる効果を奏するものである。
Moreover, combining the ultraviolet light source and the visible light source and improving the design by the irradiation pattern of each light source has been studied. For example,
しかし、特許文献１、２のように、透明または半透明のシート部材上に、紫外線発光塗料で文字や図形等の蛍光表示部を設けた場合、紫外線非照射時においても、文字や図柄の輪郭が視認され、美観性を損なうおそれがある。特に、可視光光源を照射した場合には、蛍光表示部の輪郭が視認されやすくなる。
However, as in
本発明は、上述のような問題点に鑑みなされたものであり、紫外線照射により発光する発光部を有する意匠材に関するものであり、紫外線非照射時、あるいは可視光照射時に、発光部の輪郭が視認されにくい意匠材を得ることを目的とするものである。 The present invention has been made in view of the above-described problems, and relates to a design material having a light-emitting portion that emits light when irradiated with ultraviolet rays. The outline of the light-emitting portion is not irradiated with ultraviolet rays or irradiated with visible light. It aims at obtaining the design material which is hard to be visually recognized.
本発明者は、上記目的を達成するため鋭意検討を行った結果、少なくとも１つ以上の紫外線発光部（Ａ）と、該紫外線発光部（Ａ）に隣接する非発光部（Ｂ）を有し、該紫外線発光部（Ａ）と該非発光部（Ｂ）の隠蔽率が特定条件を満たす意匠材に想到し、本発明を完成させた。 As a result of intensive studies to achieve the above object, the present inventor has at least one ultraviolet light emitting part (A) and a non-light emitting part (B) adjacent to the ultraviolet light emitting part (A). The inventors conceived a design material in which the concealment rate of the ultraviolet light emitting part (A) and the non-light emitting part (B) satisfies a specific condition, thereby completing the present invention.
すなわち、本発明目地材は、下記の特徴を有するものである。
１．透光性を有する意匠材であって、
少なくとも１つ以上の紫外線発光部（Ａ）と、該紫外線発光部（Ａ）に隣接する非発光部（Ｂ）を有し、
該紫外線発光部（Ａ）の隠蔽率が１０〜８０％、該非発光部（Ｂ）の隠蔽率が１０〜８０％であり、
該紫外線発光部（Ａ）と該非発光部（Ｂ）との隠蔽率の差が、０〜２０％であることを特徴とする意匠材。
２．該紫外線発光部（Ａ）と該非発光部（Ｂ）との６０度鏡面光沢度の差が、０〜２０であることを特徴とする１．に記載の意匠材。
３．該紫外線発光部（Ａ）と該非発光部（Ｂ）との色差（△Ｅ）が、０〜１０であることを特徴とする１．または２．に記載の意匠材。
４．１．〜３．のいずれかに記載の意匠材と、紫外線光源及び可視光光源を備えることを特徴とする構造体。
That is, the joint material of the present invention has the following characteristics.
1. A design material having translucency,
Having at least one ultraviolet light emitting part (A) and a non-light emitting part (B) adjacent to the ultraviolet light emitting part (A);
The concealing rate of the ultraviolet light emitting part (A) is 10 to 80%, the concealing rate of the non-light emitting part (B) is 10 to 80%,
A design material, wherein a difference in concealment ratio between the ultraviolet light emitting part (A) and the non-light emitting part (B) is 0 to 20%.
2. The difference in 60 degree specular gloss between the ultraviolet light emitting part (A) and the non-light emitting part (B) is 0-20. The design material described in 1.
3. The color difference (ΔE) between the ultraviolet light emitting part (A) and the non-light emitting part (B) is 0 to 10. Or 2. The design material described in 1.
4.1. ~ 3. A structural body comprising the design material according to any one of the above, an ultraviolet light source, and a visible light source.
本発明の意匠材は、少なくとも１つ以上の紫外線発光部（Ａ）と、該紫外線発光部（Ａ）に隣接する非発光部（Ｂ）を有し、該紫外線発光部（Ａ）の隠蔽率が１０〜８０％、該非発光部（Ｂ）の隠蔽率が１０〜８０％であり、該紫外線発光部（Ａ）と該非発光部（Ｂ）との差が０〜２０％であることにより、紫外線照射時には、紫外線発光部（Ａ）の発光が視認されるが、紫外線非照射時には発光部の輪郭が視認されにくく美観性に優れるものである。さらに、本発明の意匠材に可視光を照射した場合には、紫外線発光部（Ａ）及び非発光部（Ｂ）においてその境界が視認されにくく、均一な色相を呈することができる。 The design material of the present invention has at least one ultraviolet light emitting part (A) and a non-light emitting part (B) adjacent to the ultraviolet light emitting part (A), and a concealing rate of the ultraviolet light emitting part (A). Is 10 to 80%, the concealment ratio of the non-light emitting part (B) is 10 to 80%, and the difference between the ultraviolet light emitting part (A) and the non-light emitting part (B) is 0 to 20%, When the ultraviolet light is irradiated, the light emission of the ultraviolet light emitting part (A) is visually recognized. However, when the ultraviolet light is not irradiated, the outline of the light emitting part is difficult to be visually recognized, and the appearance is excellent. Furthermore, when the design material of the present invention is irradiated with visible light, the boundary between the ultraviolet light emitting part (A) and the non-light emitting part (B) is hardly visible, and a uniform hue can be exhibited.
