ABSTRACT:
A heat wave shielding lamination having improved abrasion resistance is composed of a visible light transparent substrate and an overlying composite lamination in which layers of a visible light transparent substance of a low refractive index and layers of a visible light transparent substance of a high refractive index are alternately arranged on each other, with the topmost layer being a low-refractance layer, and interfacial layers of Al.sub.2 O.sub.3 which are much thinner than the high-refractance and low-refractance layers are provided between the high-refractance and low-refractance layers.
