Patent ID: 7799504

Claim:
A film comprising a carrier sheet having thereon, in order: a) a transparent layer comprising a fluoroelastomer and having a thickness of from about 0.25 to about 10 μm, said transparent layer optionally including an adhesion promoter, and the transparent layer having a refractive index of at least 0.04 lower than the refractive index of the carrier sheet, b) an intermediate layer comprising a poly(vinyl alcohol), cellulosic polymer, poly(vinyl butyral), or hydrolyzed styrene maleic anhydride, or a thermally resistant polymer, and having a thickness of from about 0.1 to about 10 μm, said intermediate layer optionally including a crosslinking agent, coating aid, surfactant, or release-enhancing agent, c) a barrier layer comprising a poly(cyanoacrylate) or nitrocellulose, and an infrared radiation absorbing dye, and optionally metal oxide particles or crosslinking agents, d) an imageable layer comprising an infrared radiation absorbing dye and a UV-absorbing colorant dispersed in a polyurethane, poly(vinyl butyral), acrylamide polymer, nitrocellulose, or polyacetal binder, and e) an overcoat comprising a methacrylic acid copolymer and fluoropolymer particles.
