Peel apart diffusion transfer compound film unit with crosslinkable layer and borate |
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.
