Abstract
A substantially transparent multilayer web with high reflectivity in the far infra-red spectral range based on a polyester foil carrier and utilizing a metal layer, preferably of silver, has dielectric protective layers on both sides of the silver layer containing bismuth oxide, which has a desired corrosion-protection effect, as well as desirable optical properties. The bismuth content is between 10 and 85% by weight of the total metal content of the dielectric layer. Another oxide is used, either in a separate layer or as an admixture to reduce the effect of ultraviolet light.
