Abstract
A photoluminescent material is formed by curing a blend of a transparent base material and a photoluminescent pigment component, wherein the viscosity of the transparent base material is 1 Pa·s(20° C.) or more and is added in an amount of 7 to 95 wt %. Luminescence performance is further improved by taking in consideration the relation between the internal structure of a molding and its luminescence performance, thereby achieving a luminescence of predetermined brightness for an extended period of time.
