ABSTRACT:
A flame resistant composite film includes a first layer and a second layer that are joined together. The first layer has a light transmission of at least 93 percent and is substantially constructed from a radiation-cured polymer and a flame retardant material. The second layer is constructed primarily from thermoplastic polymer resin. The first and second layer when taken as a whole have a flame retardancy sufficient to pass VTM-2 standard of Oct. 27, 1988, of Underwriters' Laboratories, Inc. Also, microstructured films comprising such flame retardant films, backlit displays comprising such microstructured films, and computers comprising such displays.
