Abstract
A solar screening film for a motor vehicle windshield comprises an interference filter having one or more heat reflecting metal layers and one or more coacting reflection-suppressing layers to minimize reflection and enhance visible transmission and a gradient band continuation of the interference filter above the direct line of forward vision through a windshield when the film is disposed therein in a motor vehicle, for reflective rejection of infra-red solar energy, such band including a light-reflecting metal layer gradually increasing in thickness toward an edge of the film.
