Retroreflective Article Comprising Retroreflective Elements comprising Primary Reflective Layers and Secondary Reflective Layers

摘要

A retroreflective article including a reflective-particle-containing binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements comprise a primary reflective layer that covers a portion of the embedded surface area of the transparent microsphere, and a secondary reflective layer provided by portions of the reflective-particle-containing binder layer that are adjacent to portions of the embedded surface area of the transparent microsphere that are not covered by the primary reflective layer.
