Abstract

PURPOSE: To readily obtain reflexive plates which are suitable for number plates for vehicles, various types of signs, advertizing boards, signboards, and the like, by using a combination of light-hardened resin and thermally-hardened resin in order to align a glass balls uniformly.
CONSTITUTION: Thermally-hardened plastic resin such as alkyd series is applied on a metal plate 1 such as Al and heated, and a focus separation layer 2 with e.g. a thickness of 20 μ is formed. Ink of transparent light-hardened resin is applied thereon, and a glass-ball sticking layer 3 with e.g. a thickness of 4 μ is formed. Glass balls 4 with e.g. a reflection factor of 2.3 and a diameter 50 μ are distributed on all the surface of the undried layer 3, and the excessive balls 4 are removed by the pressure-decreasing absorption. After the glass balls 4 are aligned uniformly, the layer 3 is dried and hardened by ultraviolet illumination, thereby a surface layer 5 such as polyester-series two-liquid thermally-hardened flexible resin with e.g. a thickness of 50 μ is formed.
