ABSTRACT:
A polyvinyl chloride (PVC) composition includes an active fluorescence or phosfluorescence inducing agent which causes the composition to emit a brighter or hotter appearing light, as compared to conventional PVC compositions, when exposed to white light. In one form, the PVC composition includes barium diphenylaminesulfonate as an additive in a clear or transparent composition and light passing through the composition appears to be hotter than the impinging light. In another form, the additive is barium carbonate and the PVC includes a tinting agent to induce a colored glow when exposed to white light. In all forms, the fluorescence or phosfluorescence inducing agent is selected from a class of materials having the characteristics of creating a compound having an outer electron shell which will permit an electron shift between shells when exposed to light.
