LAMINATE THAT SCREENS INFRARED RADIATION, IS TRANSPARENT TO VISIBLE LIGHT, AND HAS AN OPTICAL WINDOW THAT ALLOWS INFRARED LIGHT TO PASS, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF

摘要

The invention relates to a laminate that screens infrared radiation, is transparent to visible light, and contains at least: (A) a first colorless, clear, transparent layer; (B) on the first colorless, clear, transparent layer, an intermediate layer that is transparent to visible light, has a screening effect (b11) toward infrared radiation, and contains i. (b1) at least one polyvinyl acetal resin as a layer-forming material and ii. (b2) at least one optical window that allows infrared light to pass; and (C) on the intermediate layer, a second colorless, clear transparent layer, lying one over the other in the specified sequence.
