Abstract of the Disclosure An imaging film, and a method of making it, comprising a flexible plastic substrate having a thin, high optical density, continuous layer of bismuth, or an alloy of bismuth, deposited on a surface thereof. The bismuth layer has a roughened outer surface. To this roughened surface a layer of a photoactive material is applied which serves as a photoresist as well as a protective overlayer for the bismuth. The photoactive material may be positive or negative working. A layer of a developable photographic emulsion may be applied to the photo- active material layer to impart camera speed to the imaging film. The photoresist side of the film has a non-shiny, essen- tially non-reflecting black surface which resembles the appearance of developed silver halide films. The substrate side of the film, on the other hand, has a metallic appearance which is easily distinguishable from the photoresist side. This feature of the film enables an operator to readily ascertain the photo- resist side of the film and speeds plate making.
