Abstract:
A light directing construction, comprising:(a) a prismatic structure having first and second surfaces, the second surface including saw-tooth formations having tilted surfaces; the prismatic structure made from a non-halogenated UV polymerizable composition; (b) a transflective metal coating provided proximate to the saw-tooth formations, the transflective metal coating having a transmission of at least 10% of visible light; and (c) a corrosion resistant feature proximate to each of the transflective metal coating and the prismatic structure, the corrosion resistant feature comprising a polymeric coating on an outer periphery of the transflective metal layer and the Prismatic structure, the corrosion resistant feature generally perpendicular to each of the prismatic structure and the transflective metal coating and providing a decrease in the sum of transmission and reflection of visible light of less than 5%.
