Abstract:
An optical element with a polarizer and a support layer is disclosed herein. The polarizer comprises an intrinsic polarizer and the support layer comprises the reaction product of: (a) from 50 to 99 parts by weight of a (meth)acryloyl oligomer having a plurality of pendant, free radically polymerizable functional groups and a Tg of greater than or equal to 20° C., (b) from 1 to 50 parts by weight of a free-radically polymerizable crosslinking agent and/or diluent monomer, and (c) from 0.001 to 5 parts by weight of an initiator. A method of forming the optical element is also disclosed herein. The optical element may be used in optical devices such as projector systems.
