ABSTRACT:
An optical element includes a polarizer having oriented vinylene segments; a substrate; and an adhesive layer disposed between the polarizer and the substrate, the adhesive layer comprising aliphatic urethane(meth)acrylate oligomer, (meth)acryl monomer, silane, and crosslinker, the crosslinker comprising ethylene glycol diacrylate and/or pentaerythritol triacrylate. The optical element can have additional layers such as hardcoat layers, additional adhesive layers, and/or additional substrates. A method of making the optical element is also disclosed, as are optical devices including the optical element.
