ABSTRACT:
There is disclosed a phosphorescent polyvinyl chloride ("PVC") film which exhibits an intense and long-lived afterglow. The phosphorescent PVC film contains a polymerized PVC-based resin, a primary and secondary plasticizer, a primary and secondary stabilizer, and a phosphorescent pigment. Within the practice of this invention, the primary stabilizer is solely a zinc-based stabilizer (non-zinc metal stabilizers are not employed); the secondary stabilizer is a tertiary organic phosphite; the primary plasticizer is a epoxidized soybean oil; the secondary plasticizer is selected from phthalates, adipates, trimellitates, azelates and phosphates; and the phosphorescent pigment is preferably a zinc sulfide phosphor. In addition to the phosphorescent PVC film, compositions and related methods are also disclosed.
