Abstract: An exposed-lens retroreflective article including a 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 reflective layer disposed between the transparent microsphere and the binder layer and at least one localized color layer that is embedded between the transparent microsphere and the reflective layer.

Abstract: There is provided a reticulated reflective article, having a longitudinal direction and a width direction, comprising: a plurality of strands of a reflective material attached to one another at bridging regions in the reflective material and separable from one another between the bridging regions to provide openings in the reflective material, wherein the openings are expandable in at least one direction to provide a variably expandable area, and wherein the reflective materials comprises a reflective major surface and a non-reflective major surface, wherein each of the openings has a longitudinal dimension, a width dimension, and each of the plurality of strands has a thickness, and wherein the reticulated reflective article is expandable in at least both of the longitudinal direction and the width direction. There is also provided a reticulated reflective article, wherein the reticulated reflective article is expandable in at least two directions.
