| 摘要 |
The present invention includes conformable retroreflective structures (2). In some embodiments, the conformable retroreflective structures (2) are also shrink resistant. The conformable retroreflective structures (2) include a transparent plasticized polyvinyl chloride film (4) having a first side and a second side; a first transparent polymer layer (6) overlying the first side of the plasticized polyvinyl chloride film (4); a second transparent polymer layer (8) overlying the second side of the plasticized polyvinyl chloride film (4); an array of retroreflective cube- comer elements (10) underlying the second transparent polymer layer (8); and a plasticizer resistant adhesive (12) underlying the array of retroreflective cube-corner elements (10). In some embodiments, the first and second transparent polymer layers (6,8) are transparent, radiation-cured polymer layers. |
