Abstract: A retroreflective article (100, 200, 300) includes a monolayer of retroreflective elements (120, 220, 320), a binder layer (110, 210, 310), and a compound comprising an aromatic bidentate moiety. The retroreflective elements (120, 220, 320) are partially embedded in the binder layer (110, 210, 310), and the compound is chemically associated with the retroreflective elements (120, 220, 320) to provide extraordinary laundering durability to the retroreflective article (100, 200, 300).
