ABSTRACT:
Luminous retroreflective sheetings have a transparent cover layer, an optical layer disposed beneath the cover layer, and a reflective layer. The optical layer includes a first polymer layer and a monolayer of beads at least partially embedded therein. The reflective layer is disposed proximate a focal plane of the monolayer of beads. The monolayer of beads includes transparent beads that, in combination with the reflective layer, retroreflect incident light. The monolayer also includes light-emitting beads that emit light under the influence of an applied voltage or ultraviolet (UV) radiation. Processes for making such sheetings are also disclosed.
