Abstract: A composite cooling film (100) comprises an ultraviolet-reflective multilayer optical film (120) and a reflective microporous layer (110) secured thereto. The ultraviolet-reflective multilayer optical film (120) hat is at least 50 percent reflective of ultraviolet radiation over a majority of the wavelength range of at least 340 but less than 400 nanometers. The reflective microporous layer (110) has a continuous phase comprising a nonfluorinated organic polymer and is diffusely reflective of solar radiation over a majority the wavelength range of 400 to 2500 nanometers, inclusive. The composite cooling film (100) has an average absorbance over the wavelength range 8-13 microns of at least 0.85. An article (1200) comprising the composite cooling film (100) adhered to a substrate (1210) is also disclosed.
