JP-A-60-199942 and JP-A-60-199942 report core-sheath fluorescent composite fibers composed of a component containing a fluorescent agent and a component not containing the fluorescent agent. This fluorescent fiber is irradiated with radiation, X-rays, ultraviolet rays, visible rays, etc., and even after blocking the irradiation light, it emits light rays that can be visually recognized by a human in a dark place for several seconds to tens of minutes. It is a so-called phosphorescent fiber, and is a metal compound such as zinc sulfide or zinc sulfide-cadmium sulfide as a fluorescent agent. The light emitted from this phosphorescent fiber is pale green, which is inferior in vividness and has low brightness.
