  • Sunshade
    Patent number: 4978181
    Abstract: A sunshade composed of a transparent substrate, a first base and a second base which are provided on the both surfaces of the substrate, an infrared ray-reflecting layer which is provided on the first base and which reflects infrared rays, and a sun light-reflecting layer which is provided on the second base and which reflects a sun radiant energy with partly transmitting visible rays. The infrared ray-reflecting layer may optionally be coated with a protective layer. At least one of the protective layer, the first base and the second base has a rough surface which may diffusively reflect the light as reflected by the infrared ray-reflecting layer and the sun light-reflecting layer. In place of formation of the rough surface, a light-diffusing agent may be incorporated into the substrate, the both bases or the protective layer.
