Presently described are retroreflective articles, such as pavement markings, that comprise transparent microspheres partially embedded in a binder ( e.g. , polymeric). Also described are microspheres ( e.g. , glass-ceramic), methods of making microspheres, as well as compositions of glass materials and compositions of glass-ceramic materials. The microspheres generally comprise lanthanide series oxide(s), titanium oxide (TiO 2 ), and optionally zirconium oxide (ZrO 2 ).

Retroreflective elements and articles that include such elements. The retroreflective elements (100) include a solid spherical core (110) having an outer surface. A first complete concentric optical interference layer (112) overlays the outer surface of the core providing a first interface between the core and the first optical interference layer, and a second complete concentric optical interference layer (122) overlays the first optical interference layer to provide a second interface between the first optical interference layer and the second optical interference layer. In some embodiments, a third complete concentric optical interference layer overlays the second optical interference layer to provide a third interface between the second optical interference layer and the third optical interference layer. The retroreflective articles include a substrate having a first major surface and a second major surface with a plurality of the retroref lective elements affixed along the first major surface of the substrate.

A functional particle transfer liner is provided that includes a release liner that has a release coating and a layer of functional particles disposed upon the release coating. The functional particles are free of abrasive particles and metal particles. The functional particle transfer particles are selected from wear-resistant particles, optical particles, biologically-active particles, photocatalytic particles, dielectric particles, fluorescent particles, and combinations thereof. Also provided is a method of making a modified substrate using the provided functional particle transfer liner.
