Abstract: For the production of positive photographic prints a composite material in strip form is used as an intermediary to form the print images and is then adhered in a continuous procedure to a main support strip such as paper. The resultant strip is then cut to separate the individual prints. The composite material has a transparent film of biaxially-oriented plastics film not more than 50.mu. thick and water-resistant and to which photosensitive emulsions are applied, and a further layer overlying the emulsions to protect them, the further layer being adhered to the main support. This layer is reflective, as by incorporation of a white pigment, so that the image is seen through the transparent film against the background of this layer rather than the main support. The reflective layer may contain other chemicals relevant to processing.
