Abstract

Disclosed herein is a radiant energy reflector comprising a laminated article mounted on a contoured support. The article includes a specularly reflective layer of silver protected on one side thereof from deterioration-inducing agents by a transparent cover sheet of polymeric material, and on the opposite side thereof by a non-polymeric protective layer of substantially inert and corrosion-resistant material. Also disclosed is a method for producing the article which yields an intimate and tenacious bond between the cover sheet, reflective layer and protective layer, thus reducing the likelihood of delamination.
