Abstract: A composite cooling film (100) comprises an antisoiling layer (160) secured to a first major surface of a reflective microporous layer (110). The reflective microporous layer (110) comprises a first fluoropolymer and is diffusely reflective of electromagnetic radiation over a majority of wavelengths in the range of 400 to 2500 nanometers. The antisoiling layer (160) has an outwardly facing antisoiling surface (162) opposite the micro-voided polymer film. An article (1100) comprising the composite cooling film (1112) secured to a substrate (1110) is also disclosed.

Abstract: A light redirecting film includes a first layer disposed on a second layer with structured major surfaces of the first and second layers facing each other. An optically reflective layer or a metal layer is disposed between the first and second layers. The first layer can be a hot melt adhesive layer and the second layer can be a polymeric layer. The first and second layers can be unitary layers. The first layer can be a first polymeric layer having a softening temperature T1 and the second layer can be a second polymeric layer having a softening temperature T2 greater than T1. Heating and/or applying pressure to the film changes an optical characteristic of the film by less than about 5%.
