Abstract
An optical material includes an adhesive formed from perfluoroalkylsulfonamidoethyl acrylate, aliphatic urethane acrylate oligomer and acrylate monomer. A film can include a first layer, a second layer disposed on the first layer and a polymerized composition disposed between the first and second layers and attaching the first layer to the second layer, the composition including perfluoroalkylsulfonamidoethyl acrylate, aliphatic urethane acrylate oligomer and acrylate monomer. A film can include a substrate and a plurality of structures disposed on the substrate, each of the structures formed by polymerizing a composition including perfluoroalkylsulfonamidoethyl acrylate, aliphatic urethane acrylate oligomer and acrylate monomer.
