Abstract: A retroreflective article comprises a binder layer and a plurality of retroreflective elements, each retroreflective element comprising a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements comprise a first locally laminated layer and a second locally laminated layer that may be reflective layers. A transfer article comprises a disposable carrier layer in which the retroreflective article is detachably disposed with at least some of the transparent microspheres in contact with the disposable carrier layer.

Abstract: Retroreflecting articles are described. In particular, retroreflecting articles including a quarter wave retarder and a retroreflecting layer are described. The retarder is rotationally invariant and the retroreflecting layer is non-depolarizing. Such articles may be useful for sensor-detectable signs, labels, and garments.

Abstract: 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.
