ABSTRACT:
The present invention provides a two-component infrared reflecting film which reflects light in the infrared region of the spectrum while suppressing second, third and fourth order reflections in the visible spectrum. The film comprises alternating layers of first (A) and second (B) diverse polymeric materials having a six layer alternating repeat unit with relative optical thicknesses of about .778A.111B.111A.778B.111A.111B. The polymeric materials differ from each other in refractive index by at least about 0.03.
