Abstract

<P>PROBLEM TO BE SOLVED: To be high in visibility by absorbing light and to be attachable even to a curved surface. <P>SOLUTION: A light storage sheet is constituted of a prism film 2 adhered onto a sheet 1, a light storing agent layer 4 formed around the prism film through a clearance 3, transparent resin layers 5 formed on the surfaces of the prism film and the light storing agent layer, and an adhesive double coated tape 6 stuck on the lower surface of the sheet. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a phosphorescent phosphorescent sheet that can be attached to bicycles, vehicles, utility poles, traffic signs, indoors such as houses and office buildings, subway premises, underground parking lots, and the like.

  Conventionally, it is known that a reflector is attached to the rear of a bicycle, etc., and light such as a street light or a vehicle headlight is reflected on the reflector to visually recognize the position of the bicycle, but this reflector has a light source. It is effective only in the case of, and is not visible when there is no light source at night.

In order to solve this problem, Patent Document 1 proposes a method in which a phosphorescent material is inserted inside the reflector, and in a place where there is no light source such as at night, the phosphorescent material that is accumulated in the daytime emits light spontaneously through the reflector. ing.
JP-A-11-305015

  However, the method disclosed in Patent Document 1 has a problem that since the phosphorescent material is inserted inside the reflector, the luminous efficiency is low and the amount of emitted light is small, making it difficult to see. Moreover, it has the problem that it is difficult to attach a reflecting plate to a curved surface.

  The present invention solves the above-mentioned conventional problems, and if the light is absorbed, the phosphorescent agent layer portion repeatedly stores and emits light, and has high visibility even in a dark place such as at night. An object of the present invention is to provide a light storage sheet with a prism that reflects light by a film, has high visibility both in the daytime and at night, and can be attached to a curved surface.

  For this purpose, the luminous sheet with prism of the present invention is formed on the prism film bonded on the sheet, the luminous agent layer formed around the prism film via a clearance, and the surfaces of the prism film and the luminous agent layer. And a double-sided adhesive tape attached to the lower surface of the sheet.

  According to the present invention, if the light is absorbed, the phosphorescent agent layer portion repeatedly stores and emits light, and has high visibility even in a dark place such as at night. Moreover, if light is received, light will be reflected by the prism film, it has high visibility in daytime or nighttime, and can also be attached to a curved surface.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show an embodiment of a light storage sheet with a prism according to the present invention, FIG. 1 (A) is a perspective view, FIG. 1 (B) is a sectional view, and FIG. 2 is a diagram for explaining a manufacturing process. It is.

  As shown in FIGS. 1 and 2, a prism film 2 having a thickness of about 0.1 mm is bonded onto a synthetic resin sheet 1 such as polypropylene. As the prism film 2, a commercially available product is adopted, and a lens film having a prism formed on the surface of the resin film or a metallic film having a metal uneven shape deposited on the surface of the resin film is adopted. A sheet such as paper may be employed instead of the synthetic resin sheet.

  On the other hand, a clearance 3 having a thickness of about 1 mm is provided on both sides of the prism film 2 on the synthetic resin sheet 1 to form a phosphorescent agent layer 4 with a thickness of about 0.11 mm by printing. As the phosphorescent agent, a commercially available material having the property of accumulating the light when there is a light source and emitting the accumulated light when there is no light source is employed.

  On the surfaces of the prism film 2 and the phosphorescent agent layer 4, a transparent resin layer 5 such as urethane having a thickness of about 0.1 mm is formed by printing. The surface of the transparent resin layer 5 is formed flat by the action of the clearance 3.

  A double-sided adhesive tape 6 is attached to the lower surface of the synthetic resin sheet 1. The prism-containing phosphorescent sheet 7 of the present invention is configured. When the phosphorescent light storage sheet 7 is attached to a bicycle, a vehicle, a utility pole, a traffic sign, etc., the release paper 6a of the double-sided adhesive tape 6 is peeled off and attached to the location.

  FIG. 3 is a plan view showing another embodiment of the phosphorescent light storage sheet of the present invention. In the present embodiment, the prism film 2 is elliptical, and the luminous agent layer 4 is provided with a clearance 3 around the prism film 2. The laminated structure is the same as that shown in FIG.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made. For example, although the phosphorescent sheet is rectangular in the example of FIG. 1 and elliptical in the example of FIG. 3, a polygonal shape such as a triangle or a quadrangle, or any other shape can be employed.

1 shows an embodiment of a phosphorescent light storage sheet of the present invention, in which FIG. (A) is a perspective view, and FIG. It is a figure for demonstrating the manufacturing process of this invention. It is a top view which shows other embodiment of the light storage sheet | seat with a prism of this invention.
