Wrinkle resistant infrared reflecting film and non-planar laminate articles made therefrom
First Claim
1. An article comprising a birefringent dielectric multilayer film sandwiched between two substrates, the film reflecting at least 50% of light in a band at least 100 nm wide in a wavelength region of interest, wherein the film is heat set at a temperature sufficient to render the film capable of shrinking so as to conform without substantial wrinkling when positioned between the two substrates and heated.

Abstract
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.
