PHOSPHORESCENT TYPE GUIDE SIGN BOARD

摘要

A phosphorescent type guide sign board is provided to distinguish the content of the guide sign board by re-emission of the light accumulated in the guide sign board. A transparent color ink layer(2) of a green system is coated on a front side of a transparent material sheet(1) with the thickness of 2 to 20u. A reflective ink layer(3) is formed in the part excluding the transparent color ink layer among the inner part of the transparent material sheet. A phosphorescent ink layer(4) and a transparent coating layer(5) are successively formed. The phosphorescent type guide sign board is inserted into an exit case(7) used without a battery.
