ABSTRACT:
Multiple layer light transmissive laminates and a method for making them. Such laminates are particularly adapted for use as glazing materials. The laminates retain light transmissivity after exposure to elevated temperatures. The laminates include two or more layers of light transmissive sheets such as glass, polymerized methylmethacrylate and the like, bonded together by means of a thermosetting resin which is cured in the absence of free oxygen and in the absence of oxygen-generating polymerization initiators. The curing is achieved by means of radiation energy delivered through at least one light-transmissive sheet into the resin.
