ABSTRACT:
Photographic assemblages and processes are described wherein a stripping layer is employed to enable an image-receiving layer to be separated from the rest of the assemblage after processing. Each side of the stripping layer has a hydrophilic layer immediately adjacent thereto, only one of which contains a surfactant-like material having a hydrocarbon fatty tail of at least eight carbon atoms which is remote from a polar group, the material being present in an amount sufficient to enable a clean separation between the image-receiving layer and the portion of the assemblage containing the silver halide emulsion layer.
Transparencies or prints which are less bulky and free from surface defects at the stripping layer interface can thereby be obtained from integral assemblages.
