RETROREFLECTIVE ELEMENTS

摘要

A process and retroreflective elements are provided. The process of preparing a retroreflective element includes the steps of: (a) combining a bed of optical elements and one or more core elements comprising a thermoplastic material; and (b) agitating the combination of optical elements and core elements for a sufficient period of time and at a sufficient temperature to coat the optical elements onto the core elements to form retroreflective elements.
