A non-halogenated composition having a high index of refraction, preferably greater than 1.55, comprising a vinyl monomer, such as methyl styrene. The cured composition is particularly suited for having a metal layer, such as silver, applied thereto. In one embodiment, the composition can be used to form a microreplicated prismatic structure. Preferably, the structure has two sides, where one side is substantially smooth and the other includes saw-tooth formations having tilted surfaces. A metal layer may be present on one or more sides of the prismatic substrate having the saw-tooth formations.
