ABSTRACT:
A transparent heat-absorbent multi-layer structure comprising, (A) a first layer, and (B) a second layer is described. The first layer (A) contains at least one organic infrared absorber (e.g., a phthalocyanine) and at least one ultraviolet absorber (e.g., a benzotriazole), and the second layer (B) contains at least one ultraviolet absorber and is substantially free of organic infrared absorbers. The first layer (A) is the only layer in the multi-layer structure that contains an organic infrared absorber. Also described is a method of preparing the multi-layer structure. Molded articles that may comprise the multi-layer structure of the present invention include glazings, such as automotive glazings.
