ABSTRACT:
A layer of glass, and an optically clear or transparent coating layer bonded to at least one surface of the glass layer by an interposed layer of optically clear adhesive having a peel strength of at least 3,000 grams per square inch. The coating layer generally includes a plurality of polymeric plies or strata, which are preferably made of a polyester material. The adhesive layer is preferably a pressure sensitive acrylic resin. The coating layer preferably includes an ultraviolet absorbing polyester ply, a reflective polyester ply which will generally include a metallized surface, and an outermost scratch resistant ply that prevents scratching of the coating layer which will reduce optical transparency. The coating layer may additionally include a protective polyester ply adjacent to the metallized surface of the reflective ply.
