ENCAPSULATED-LENS RETROREFLECTIVE SHEETING

摘要

An encapsulated-lens retroreflective sheeting comprising a monolayer of lenses partially embedded in a binder layer, a specularly reflective layer underlying the lenses in optical association therewith, and a cover film bonded to the binder layer, wherein said cover film comprises a polyester film or a polyvinyl chloride film. The cover film has an adhesion bonding interface on the surface in at least partial contact with the binder layer. The sheetings of the invention exhibit improved dimensional stability under heat and shrink resistance while maintaining impact resistance and other desirable properties of pavement markings.
