PHOTOLUMINESCENT RETROREFLECTIVE SHEETING

摘要

A photoluminescent retroreflective sheeting (24) for use in structures when a power outage occurs. Guidance systems are made from this sheeting to mark exits and escape routes as well as possible hazards and safety devices. The novel sheeting (24) includes photoluminescent properties that glow in the dark as well as retroreflective properties that retroreflect light incident upon the same sheet (24) such that only one sheet has to be used rather than individual sheets with separate properties.
