Abstract
Coating for infrared transparency films and thermally imageable films and films prepared with such coating. The coating comprises a copolymer formed from (a) at least one fluorocarbon monomer and (b) at least one monomer which imparts hardness to the copolymer. The coating serves to prevent the transfer of toner powder from an original which is in actuality an electrophotographic copy to the transparency film. The copolymer may contain from about 12 percent to about 85 percent fluorocarbon monomer, the remainder being the monomer which imparts hardness to the coating. Suitable monomers for imparting hardness to the copolymer include acrylates, methacrylates, acrylamides, methacrylamides, acrylonitriles, methacrylonitriles, and styrenes.
