Title
(EN) CUBE CORNER CAVITY BASED RETROREFLECTORS WITH TRANSPARENT FILL MATERIAL
(FR) RETROREFLECTEURS UTILISANT UNE CAVITE EN FORME DE TRIEDRE TRIRECTANGLE DOTES D'UNE MATIERE DE REMPLISSAGE TRANSPARENTE
Abstract
(EN)
Retroreflective sheeting (10) includes a body layer (12) having a structured surface (14) with recessed faces (18) forming cube corner cavities (22). A reflective film (24) is disposed at least on the recessed faces (18), and a fill material (26) fills the cube corner cavities (22). The fill material (26) comprises radiation-curable materials, adhesives, or both, and preferably transparent radiation-curable pressure-sensitive adhesives. The fill material (26) preferably forms a continuous layer covering both the recessed faces (18) and upper portions of the structured surface (20). A transparent cover layer (16) preferably contacts the fill material layer.
(FR)
L'invention concerne des feuilles rétroréfléchissantes (10) se composant d'une couche principale (12) dont la surface (14) présente des faces évidées (18) formant des cavités (22) de forme trièdre trirectangle. Un film réfléchissant (24) est placé au moins sur les faces évidées (18) et une matière de remplissage (26) comble les cavités (22) de forme trièdre trirectangle. La matière de remplissage (26) comprend des matières et/ou des adhésifs durcissables par rayonnement, de préférence des adhésifs autocollants transparents durcissables par rayonnement. La matière de remplissage (26) forme de préférence une couche continue recouvrant à la fois les faces évidées (18) et les parties supérieures de la surface structurée (20). Une couche de couverture transparente (16) entre de préférence en contact avec la couche de matière de remplissage.
