Abstract

A cover-substrate support material is provided with a layer reflecting thermal radiation preferably between 5 and 25 micron wavelength and there is deposited thereon a protective layer comprising arbitrarily adjustable absorption bands in the region from 400 to 900 nm wavelengths and extensively transparent in the reflecting region of the thermally reflecting layer.
