MICROPRISM REFLECTIVE SHEETING WITH IMPROVED RETENTION OF REFLECTIVITY

摘要

Flexible retroreflective sheeting, and products therefrom, fabricated from an elastic substantially linear olefin polymer are found to exhibit significantly enhanced retention of retroreflectivity and do not require the addition of plasticizers. The retroreflective sheeting of the invention is a surprisingly good replacement for polyvinyl chloride sheeting which heretofore have shown poor retention of retroreflectivity and have required addition of plasticizers for optimal flexibility and handling.
