Summary:The present disclosure generally relates to retroreflective sheeting including a topcoat and to methods of making such sheeting. In some embodiments, the retroreflective sheeting includes (1) a first major surface that is a structured surface having a structure imparted by a plurality of prismatic cube corner elements; (2) a second major surface opposite the first major surface, the second major surface being substantially planar and including a polycarbonate; and (3) a topcoat adjacent to at least a portion of the second major surface and the topcoat including a solvent-based composition. Cette divulgation concerne de manière générale des feuilles rétroréfléchissantes comprenant une couche de finition et des procédés pour les fabriquer. Dans certains modes de réalisation, la feuille rétroréfléchissante comprend (1) une première surface majeure qui est une surface structurée ayant une structure conférée par une pluralité d'éléments prismatiques à trièdres trirectangles ; (2) une seconde surface majeure à l'opposé de la première, la seconde surface majeure étant sensiblement plane et comprenant un polycarbonate ; et (3) une couche de finition adjacente au moins à une partie de la seconde surface majeure, ladite couche de finition comprenant une composition à base d'un solvant.
