Abstract: A 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 include a reflective layer that is a locally-laminated reflective layer that is embedded between the transparent microsphere and the binder layer. At least some of the locally-laminated reflective layers may be localized reflective layers.
