摘要： Image-receiving elements for use in photographic diffusion transfer products and processes and including a unitary image-receiving and decolorizing layer are disclosed. The unitary image-receiving and decolorizing layer comprises a mixture of gelatin, an organic monobasic or polybasic acid or anhydride and a copolymeric mordant comprising recurring units from a vinylpyridine and from a copolymerizable vinylbenzyl quaternary ammonium salt. The image-receiving elements can be used in diffusion transfer products and processes for the provision of color images which appear satisfactorily to emerge from a white background and which exhibit desirable densitometric characteristics.

摘要： A slide blank comprises a support at least part of which is essentially transparent; an imageable layer superposed on one face of the support, the imageable layer not being substantially photosensitive but comprising a color-forming composition, which, upon imagewise exposure to actinic radiation, forms a colored material, thereby forming in the imageable layer an image which can be viewed in transmission; and a protective layer superposed on the imageable layer on the opposed side thereof from the support, at least part of the protective layer being essentially transparent; the support, imageable layer and protective layer being secured together to form a slide blank having a thickness of at least about 0.8 mm, and the thickness of the protective layer being such that no part of the imageable layer containing the color-forming composition is more than about 0.2 mm from one external surface of the slide blank. This slide blank can be imaged to produce a ready-mounted slide.

摘要： An imaging medium comprises a layer, depolymerizable by exposure to actinic radiation and undergoing a reduction in cohesivity upon at least partial depolymerization, disposed adjacent a layer of an imaging material, which has a cohesive strength greater than the cohesive strength of the depolymerizable layer after 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 lower in cohesivity than the unexposed areas. The exposed areas of the imaging material are then removed from the depolymerizable layer.
