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.

Abstract: An exposed lens retroreflective article (100), transfer articles comprising same, and methods of making same. The retroreflective article can include a binder layer (114); a layer of transparent microspheres (108) partially embedded in the binder layer; and reflective layer (110) disposed between the binder layer and the microspheres. The reflective layer (110) can include a dielectric mirror, which can include a first stack (115) and a second stack (111) positioned in planar contact with the first stack, wherein each of the first stack and the second stack comprises at least one bilayer (119), wherein each bilayer comprises a first material with a first bonding group and a second material with a complementary second bonding group. The transfer article can include the retroreflective article and a carrier web. The method can include partially embedding transparent microspheres in a carrier web; applying the reflective layer to the microspheres, and applying a binder layer composition to the reflective layer.
