Wrinkle resistant infrared reflecting film and non-planar laminate articles made therefrom

摘要

A birefringent dielectric multilayer film that reflects in a wavelength region of interest, and preferably reflects at least 50% of light in a band at least 100 nm wide, preferably positioned between wavelengths from about 700 nm to about 2000 nm. The film is heat set to render the film capable of shrinking to conform without substantial wrinkling to a substrate having a compound curvature. The film may be laminated to form a wide variety of non-planar articles.
