Title
(EN) DURABLE, OPEN-FACED RETROREFLECTIVE PRISMATIC CONSTRUCTION
(FR) CONSTRUCTION PRISMATIQUE A SURFACES DECOUVERTES, RETROREFLECHISSANTE, ET DURABLE
Abstract
(EN)
Retroreflective sheeting and a method for making the same includes a plurality of open-faced cube-corner surfaces formed from a substantially rigid material to keep the cube-corner surfaces from flexing. An optical coating is formed on the surfaces, and a fill layer is attached to at least a portion of the optical coating. A plurality of voids form the open-faced cube-corner surfaces.
(FR)
L'invention concerne une feuille rétroréfléchissante ainsi qu'un procédé de fabrication associé, consistant à produire une feuille comprenant plusieurs surfaces prismatiques à surfaces découvertes, à partir d'un matériau sensiblement rigide, de manière à empêcher ces surfaces prismatiques de se plier, puis à former un revêtement optique sur les surfaces, et à attacher une couche de remplissage à au moins une portion du revêtement optique, plusieurs vides formant les surfaces prismatiques, à faces découvertes.
