摘要:
An imaging process uses an imaging medium comprising a polymer having a plurality of first groups. This polymer is imagewise contacted with an imaging reagent comprising a plurality of second groups, thus causing, in the areas of the medium exposed to the imaging reagent, the second groups to react with the first groups and form a colored material, and thereby forming an image on the imaging medium. One of the first and second groups comprises a benzotriazinone or benzothiatriazine-4,4-dioxide benzotriazinone moiety and the other comprises a naphthol or a pyrazalone moiety.
摘要:
Polymers containing pyridinium ylide moieties are subjected to actinic irradiation to convert the pyridinium ylide moieties to water-insoluble or hydrophobic N-acyl-diazepine polymers. The polymeric pyridinium ylides can be used for the waterproofing or hydrophobization of surfaces and for the production of printing plates, photoresists, printed circuit boards and the like.

There are disclosed novel compounds which are represented by the formula ##STR1## wherein X represents the nonmetallic atoms necessary to form a nucleus which completes a 5- or 6-membered heterocyclic moiety, R is H, an alkali metal or a group which is cleavable in aqueous alkaline medium and Z is H, alkyl having from 1 to 10 carbon atoms, aralkyl such as benzyl or phenethyl, phenyl or substituted phenyl. The compounds are useful in photographic applications.

Novel polymers comprising recurring units capable of undergoing .beta.-elimination in an alkaline environment are disclosed for use in diffusion control layers in diffusion transfer film units.
摘要:
Novel photographic processing compositions including a polymeric oxime viscosity-increasing reagent for processing an exposed film unit to provide a photographic image. While this photographic image may be in black-and-white or in color and prepared by any of the heretofore known systems, of particular interest are color diffusion transfer systems for preparing a color image viewable without separation of any of the components or layers of the photographic product. The invention also includes a novel class of polymeric oximes which may be employed in such compositions.

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.
