摘要:
Disclosed are methods (100) for preparing a laminate incorporable to a surface of an optical lens and methods (500) for incorporating the laminate on the surface of the optical lens. The laminate is prepared by laminating an optical film (202a, 202b), such as a polycarbonate film, on each side of a functional film using an adhesive that is capable of preventing optical defects in the laminates during a thermoforming process and an injection molding process. The adhesive has optimal thermomechanical properties that include that the optical film (202a, 202b) coated with said adhesive has a modulus by compression greater than 6×106 Pa, and preferably greater than 2×108 Pa at a temperature from about 130° C. to 150° C. The laminate is incorporated on the optical lens via thermoforming followed by injection molding with overmolding technology.
