Abstract
A composite cooling film including non-fluorinated organic polymeric layer, a metal layer disposed inwardly of the non-fluorinated organic polymeric layer, and an antisoiling, ultraviolet-absorbing hardcoat layer that is disposed outwardly of the non-fluorinated organic polymeric layer.
Claims26
A composite cooling film comprising:
- a non-fluorinated organic polymeric layer having an absorbance of at least 0.80 in a wavelength range of from 8 to 13 microns;
- a metal layer that is disposed inwardly of the non-fluorinated organic polymeric layer,
- wherein the non-fluorinated organic polymeric layer and the metal layer collectively exhibit an average reflectance of electromagnetic radiation of at least 85% over a wavelength range from 400 to 2500 nanometers;
- and,
- an antisoiling, ultraviolet-absorbing hardcoat layer of organic polymeric material, the antisoiling, ultraviolet-absorbing hardcoat layer being disposed outwardly of the non-fluorinated organic polymeric layer and comprising an outwardly-facing, exposed antisoiling surface,
- wherein the composite cooling film has an average absorbance over the wavelength range 8-13 microns of at least 0.85.
