A phosphorescent article having a first transparent resin layer, a phosphorescent layer, and a second transparent resin layer sequentially superposed in the order mentioned on a supporting layer possessed of a reflective surface. The phosphorescent layer is coated in a tightly sealed state with the first and second transparent resin layers. Preferably the second transparent resin layer has a projecting part so formed as to protrude from the surface of the part thereof which covers the phosphorescent layer, namely in the part which corresponds to the underlying phosphorescent layer, and a surface layer (printed layer) is printed or applied on the part of the surface other than the projecting part, namely on the surface of the part in which the phosphorescent layer does not exist. SrAl2O4 is used as a phosphorescent pigment to be contained in the phosphorescent layer and a transparent resin containing no ultraviolet absorbent is used for the first and second transparent resin layers.
