Abstract
A transparent phosphorescence material includes a mixture of a phosphorescent material powder obtained by pulverizing a phosphorescent material, a resin of a phenol, and a curing agent. The phosphorescent material powder has an average particle diameter of 10 to 20 μm, the resin is a modified bisphenol, and the curing agent is an aliphatic polyamine. A mass ratio of the phosphorescent material powder, the resin, and the curing agent in the mixture is such that the phosphorescent material powder is 15 to 25 wt %, the resin is 50 to 70 wt %, and the curing agent is 15 to 25 wt %. When the transparent phosphorescence material is applied to a surface of a metal substrate, the surface of the metal substrate is visible through the transparent phosphorescence material. The transparent phosphorescence material emits a light due to phosphorescence in the dark.
