Abstract: The present invention relates to a method of preparing a photochromic-dichroic film. The method includes forming a molten extrudate that includes a first molten thermoplastic layer that includes one or more photochromic-dichroic compounds, that is interposed between separate second and third outer molten thermoplastic layers. The molten extrudate is cooled so as to form a multilayer film that includes a first layer that includes one or more photochromic-dichroic compounds, that is interposed between separate second and third outer layers. The second and third outer layers are removed from the first layer of the multilayer film. The resulting sole first layer, which is retained, defines the photochromic-dichroic layer, which exhibits reduced or minimal optical distortion.
