Abstract:
1. A laminate film adapted for use in protecting an exterior surface of a vehicle windshield, comprising: a flexible substrate comprising a first surface and a second surface, the flexible substrate having a first composition; a first flexible adhesive layer adhered to the first surface of the flexible substrate; a flexible scratch-resistant coating adhered to the first flexible adhesive layer, the flexible scratch-resistant coating having a second composition that is different and more scratch-resistant than the first composition; and a second flexible adhesive layer adhered to the second surface of the flexible substrate, the flexible substrate, the flexible scratch-resistant coating, and the first and second flexible adhesive layers being selected, and the laminate film having an overall thickness, so as to provide the laminate film with a consistent refractive index across the laminate film so as to be substantially optically transparent, the laminate film being shock absorbing and flexible so as to readily conform to a curvature of an exterior surface of a vehicle windshield or be wound and stored as a roll while remaining substantially optically transparent and shock absorbing and retaining a consistent refractive index.
