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).
Un article rétroréflecteur (100, 200, 300) comporte une monocouche d'éléments rétroréflecteurs (120, 220, 320), une couche de liant (110, 210, 310), et un composé contenant un groupe aromatique bidenté. Les éléments rétroréflecteurs (120, 220, 320) sont partiellement encastrés dans la couche de liant (110, 210, 310), et le composé est lié chimiquement aux éléments rétroréflecteurs (120, 220, 320), ce qui confère à l'article rétroréflecteur (100, 200, 300) une résistance au lavage exceptionnelle.
