The present invention relates to an advertisement sheet using a reflection sheet, and more particularly, to an advertisement sheet using a microprism retroreflective sheet capable of high luminance reflection and a method of manufacturing the same.

The retroreflective sheet is used as a night recognition safety belt or traffic sign because light is reflected back to the light incident side unlike the total reflection or diffuse reflection. The retroreflective sheet uses glass beads or microprisms as its reflective material. The microprism retroreflective sheet is capable of retroreflecting toward the light source by refraction of light by the microprism reflective surface formed on one side thereof.

Korean Utility Model Registration No. 243310 describes a reflective paper having both a retroreflective function and a reflex reflection function as described above. FIG. 1 is a schematic diagram showing the configuration of a composite reflector in which a diffuse reflection surface and a retroreflection surface described in Utility Model Registration No. 243310 are formed together. As shown in FIG. 1, the conventional composite reflective paper 100 forms a microprism-shaped uneven surface 120 on one side of the PVC fabric 110 of the transparent thin plate material, and a diffuse reflection surface 130 on the other side thereof. It is formed. At this time, the diffuse reflection surface 130 is formed by uniformly forming the fine grooves (131, 132) different from each other on the front.

Since the compound reflector 100 is retroreflected by the microprism-shaped concave-convex surface 120 when light is incident, diffuse reflection is simultaneously performed by the grooves 131 and 132 having different forming angles. Recognition has an advantage.

In addition, Korean Utility Model Registration No. 258086 describes a billboard using a reflective sheet. FIG. 2A is a perspective view of a billboard using the reflective sheet described in Utility Model Registration No. 258086, and FIG. 2B is a cross-sectional view of the billboard shown in FIG. 2A taken along line A-A.

The billboard 200 was configured.

As described above, in the related art, a glass sheet or a microprism is used as a reflective material to implement a reflective sheet, and a night recognition safety belt or a traffic sign and a billboard are manufactured using the reflective sheet. However, the reflective sheet using the glass beads as a reflective material is attached to about 8,000-10,000 / ㎠ glass beads according to the manufacturing method, but has a disadvantage of low reflectance because it is vulnerable to water and moisture. In addition, the reflective sheet using glass beads as a reflective material has a disadvantage in that the manufacturing process is complicated and the production cost is high. On the other hand, the retroreflective sheet using the microprism as a reflective material is configured to have about 12,000 / cm 2 prism and has a high reflectance because it is stronger in water and moisture than glass beads. In addition, the retroreflective sheet using the microprism as a reflective material has the advantage of low production cost because the manufacturing process is relatively simple.
