ENHANCED HEAT MIRROR FILMS.

摘要

A heat mirror film containing visible light-transmissive and infrared reflective film comprising a birefringent dielectric multilayer support that reflects at least 50% of light in a band at least 100 nm wide in a wavelength region of interest, a metal or metal alloy layer whose thickness is such that the film is visible light-transmissive and its reflection band is broadened, and a crosslinked polymeric layer has improved infrared reflecting properties. The film can be joined or laminated into glazing (especially non-planar vehicular safety glazing) with reduced likelihood that the metal or metal alloy layer will be damaged or distorted.
