Abstract: A method of making an infrared-reflecting optically transparent assembly comprises: coating a curable composition onto a major surface of an optically transparent thermoplastic polymer film; at least partially curing the curable composition, which may be optionally at least partially dried, to provide a thermoformable composite film; and laminating the thermoformable composite film to an infrared-reflecting multilayer optical film to provide the infrared-reflecting optically transparent assembly. The curable composition comprises urethane (meth)acrylate compound, (meth)acrylate monomer, and silicone (meth)acrylate. The infrared-reflecting optically transparent assembly and methods of including it in an infrared-reflecting lens assembly are also disclosed.
