〔産業上の利用分野〕
本発明は、屋外屋内とくに道路上の表示物に使用する反
射性模様シートに係るものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a reflective patterned sheet for use outdoors, indoors, and especially for road displays.
従来この種の反射性模様シートは透明微小球５１による
再帰反射シートが使用されており、その透明微小球５１
による再帰反射シート構造は大別して第２．３図に示す
ように躇出型ａと封入型すとに分けられる。Conventionally, this type of reflective pattern sheet uses a retroreflective sheet using transparent microspheres 51, and the transparent microspheres 51
The structure of the retroreflective sheet according to the invention can be roughly divided into a heliometric type a and an encapsulated type as shown in Fig. 2.3.
落出型ａは封入型に比べ輝度が良好となり面かも構造が
簡単で、従って、製作費用が安価であるが、理論的には
空気と同じ屈折率の着色を透明微小球５１表面に施さな
ければならず、従って、露出型ａの場合は着色しても反
射光輝は皆無となる。The falling type a has better brightness and a simpler surface structure than the sealed type, and is therefore cheaper to manufacture, but theoretically the surface of the transparent microsphere 51 must be colored with the same refractive index as air. Therefore, in the case of exposure type a, there is no reflected brilliance even if it is colored.
その点封入型すは着色処理が容鶴に行なえるが前記した
ように輝度の点、姫作費用の点で問題がある。Although the encapsulated mold can be easily colored, as mentioned above, there are problems in terms of brightness and production costs.
尚、第２．３図中符号５２は反射面である５゜〔発明が
解決しようとする課題〕
本発明は、反射輝度が良好で而かも、構造が簡単であり
、製作費用の安価な透明微小球の露出型再帰反射機構を
用いた反射性模様シートを提供することを技術的課題と
するものである。In addition, the reference numeral 52 in Fig. 2.3 is a reflective surface 5゜ [Problem to be solved by the invention] The present invention provides a transparent material that has good reflective brightness, has a simple structure, and is inexpensive to manufacture. The technical object is to provide a reflective patterned sheet using an exposed microsphere retroreflection mechanism.
添付図面を参照して本発明の詳細な説明ケる。 A detailed description of the invention will be given with reference to the accompanying drawings.

徴とする反射性模様シートに係るものである。A transparent colored pattern coating 3 having a thickness of 5% or less of the diameter of the transparent microspheres 5 described later is formed on the reflective surface 2 of the sheet I having a smooth light reflecting surface 2, and is adhered to this transparent colored pattern coating 3. The present invention relates to a reflective patterned sheet characterized in that transparent microspheres 5 are arranged in a single layer with an agent 4 interposed therebetween.
また、前記透明微小球５が直径１０〜３００μｌで屈折

ー トに係るものである。The reflective pattern sheet according to claim 1, wherein the transparent microspheres 5 have a diameter of 10 to 300 μl and a refractive index of 1.3 to 2.3.
また、前記透明着色模様被膜３をグラビア印刷で影成し
た請求項１記載の反射性模様シートに係るものである。The reflective pattern sheet according to claim 1, wherein the transparent colored pattern coating 3 is formed by gravure printing.
露出型ａの再帰反射構造は第１図に示す様に空気中に露
出された透明微小球５の底面に光反射面２を施した構造
なので透明微小球５の露出外表面に透明着色印刷しても
光の屈折の関係で再帰反射しなくなる。As shown in FIG. 1, the exposed type A retroreflective structure has a light reflecting surface 2 on the bottom surface of the transparent microspheres 5 exposed to the air, so the exposed outer surface of the transparent microspheres 5 is printed with a transparent color. However, due to the refraction of light, there is no retroreflection.
そこで出願人は、シート１の光反射面２の土に極く薄い
透明着色波！Ｉ３を影成し、この透明着色被膜３に接着
剤４を介して透明微小球５を単層配列してその再帰反射
性能を調へてみたところ再帰反射性能が衰えていないこ
とが確認された。同時にこの場合透明着色被膜３の厚み
は透明微小球５の直径の５％以下でなければならないこ
とも判明しｔこ。Therefore, the applicant created an ultra-thin transparent colored wave on the light-reflecting surface 2 of the sheet 1! I3, transparent microspheres 5 were arranged in a single layer on this transparent colored film 3 via an adhesive 4, and the retroreflection performance was examined, and it was confirmed that the retroreflection performance had not deteriorated. . At the same time, it has been found that in this case, the thickness of the transparent colored coating 3 must be 5% or less of the diameter of the transparent microspheres 5.
以」−の研究により本発明は完成（４ノーのである。Through the following research, the present invention was completed (4 No.).

形で反射する。The light incident on the transparent microspheres 5 passes through the transparent colored pattern coating 3 and is reflected by the light reflecting surface 2, and passes through the transparent colored pattern coating 3 again from the transparent microspheres 5 to the light source where the light reflects the color of the transparent colored pattern coating 3. Reflect in shape.
