    摘要： An imaging medium comprises a layer, depolymerizable by exposure to actinic radiation and substantially non-tacky prior to depolymerization but becoming tacky upon at least partial depolymerization, disposed adjacent a layer of an imaging material, which has a cohesive strength greater than the adhesive strength between the imaging material and the depolymerizable layer prior to depolymerization. This medium is imagewise exposed to radiation, thereby causing at least partial depolymerization of the polymer in the exposed areas, so rendering these exposed areas tacky and firmly attaching exposed areas of the imaging material layer to the depolymerizable layer. The unexposed areas of the imaging material are then removed from the depolymerizable layer.

    摘要： There are described a diffusion transfer photographic film unit of the type wherein an image-receiving element is designed to be separated from a photosensitive element after photoexposure and processing and a photographic process which utilizes the film unit. The photographic film unit comprises a photosensitive element including a support carrying at least one silver halide emulsion, an image-receiving element comprising a support, an image-receiving layer and, optionally, an overcoat layer and/or a strip-coat layer. At least one of the image-receiving layer, overcoat layer or strip-coat layer includes a "crosslinkable material" which is crosslinked during processing. The film unit further includes means for providing an aqueous alkaline processing composition to the photosensitive element and the image-receiving element for developing an image. The aqueous alkaline processing composition includes a borate compound for crosslinking the crosslinkable material of the image-receiving element during processing.
