Laminated plastic sheets composed of a first layer of a film of an aromatic thermoplastic polycarbonate or polyarylsulfone and a second layer of a film of a thermoplastic copolymer of tetrafluoroethylene and of a completely or partially fluorinated vinyl alkyl ether or vinylalkane and an interlayer of a polyurethane adhesive between the film layers to secure the film layers to one another. Also disclosed are methods for producing the laminated plastic sheet and articles formed therefrom. Such sheets and articles possess improved printability, thermo-formability, resistance to ignition and produce minimal smoke on burning.
