Multilayer infrared reflecting film with high and smooth transmission in visible wavelength region and laminate articles made therefrom |
摘要 |
A multilayer film article is disclosed. The film includes an infrared light reflecting multilayer film having alternating layers of a first polymer type and a second polymer type and an infrared light absorbing or reflecting layer adjacent the multilayer film. The film includes a multilayer stack composed of alternating optical layers of first and second diverse polymers A, B. The optical layers when counted from one end of a first effective optical packet form a plurality of unit cells each having six optical layers arranged in relative optical thicknesses in a first cyclic permutation of 7A1B1A7B1A1B. At normal incidence the first effective optical packet provides a reflection band at infrared wavelengths and substantially transmits light at visible wavelengths.
