Abstract
The present invention relates to a vehicle sunroof having variable optical transmission and a method for making the same. Specifically, a vehicle sunroof is provided that, in accordance with the present invention, comprises a relatively thin film having variable optical transmission and a relatively thick substrate layer of clear plastic material adhered to a surface of the relatively thin film. The relatively thin film is positioned in a first molding die of a pair of injection molding dies such that it is adjacent a surface of the first die. The relatively thick substrate layer is adhered to one surface of the relatively thin film while in contact therewith in a molten state under heat and pressure within a cavity defined by the injection molding dies.
