RETROREFLECTIVE SHEETING WITH EMBEDDED RETROREFLECTIVE ELEMENTS IN A BINDER LAYER WITH SHAPE MEMORY AND METHOD FOR FORMING THE SAME

摘要

A method for forming retroreflective sheeting comprising a binder layer having a first surface with protrusions thereon and a plurality of retroreflective elements partially embedded in the surface, wherein the method comprises forming the binder layer in a first profile, embedding the retroreflective elements therein, and then activating that binder layer such that it is restored to the first profile via shape memory.
