    Abstract: A retroreflective structure includes an outer layer having a first transparent plastic layer having a fluorescent colorant and a second transparent plastic layer having a non-fluorescent colorant which is significantly more stable to prolonged exposure to ultraviolet light than the fluorescent colorant. The second transparent plastic layer is bonded to the first transparent plastic layer. An array of retroreflective elements is bonded to the top layer. An inner layer is bonded to a second side of the array of retroreflective prism elements.

    Abstract: A durable reusable polymeric mold (10) for casting a microstructure sheet having an array of prism elements and a method for forming the microstructure sheet are disclosed. A polymeric mold has a facet side (14) and a base side (16) comprising an array of prism elements upon which a radiation cured sheet can be formed. A protective surface layer (20) can be formed on the facet side (14) of the polymeric mold (10). The protective surface layer (20) is sufficiently opaque to radiation to protect the polymeric mold (10) from damage when the curable sheet (22) is formed and is sufficiently bonded to the polymeric mold to allow the cured sheet (22) to be removed from the protective surface layer (20) while not substantially removing the protective surface layer (20) from the polymeric mold (10). The microstructure sheet can be used as a retroreflective structure.
