Abstract: A curl resistant transmissively readable photoplastic film is produced having a base ply of polyethylene terephthalate to one side of which is laminated, in sequence, a light transmissive layer of electrically conductive particles, a primer layer of a dimethyl-phenylene oxide polymer, and a photoplastic layer. The latter layer may be formed from a mixture of 75% by weight of an intermediate molecular weight (800-5,000) polystyrene and 25% by weight of a polymolecular plasticizer derived from alpha-methylstyrene to which mixture has been added about 3.3% of the total weight of solids of very fine particle size copper phthalocyanine. To the other side of the base ply is laminated a layer of a solvent deposited methyl methacrylate polymer. When the photoplastic layer is about 17 to 18 microns thick the methyl methacrylate layer may be about 4 to 6 microns thick.
