    摘要: A method and apparatus for applying processing fluid to the light sensitive emulsion surface of a photographic film strip contained in a multi-purpose cassette and in which a coating of processing fluid deposited directly onto the film strip is delimited by a doctoring surface moved in a direction opposite to the direction of film strip travel during passage thereof at the doctoring surface. The doctoring surface may be the cylindrical surface of a roller or it may be effected by a portion of the film strip itself. In the latter instance, the film strip is constrained to a loop-like path during processing by appropriate guide means so that one of the oppositely facing surfaces in the neck of the loop provides the doctoring surface for the coating on the other of such surfaces.

    摘要: Integral negative-positive reflection prints are obtained by a diffusion transfer process wherein the image-receiving element is impregnated with a processing liquid. The image-receiving element comprises a transparent support, an image-receiving layer, a light-reflecting layer and an opaque layer.
