摘要： There are described novel photographic processing compositions, film units and processes for use in diffusion transfer photographic systems. More particularly, there is described a method for forming a diffusion transfer image photographic processing of diffusion transfer photographic film units in the presence of hypoxanthine and inosine. Diffusion transfer photographic systems utilizing the novel photographic element or method of the present invention exhibit substantially fewer, if any, crystals on the final image of the finished photograph post-processing.

摘要： Multi-functional vinylbenzyl and vinylphenyl pendant thymine (and uracil) groups are disclosed. The monomers can be used for the production of polymers useful in photoresist and other compositions as a function of the crosslinking reactivity of the pendant groups. Images in polymer are provided by exposure to actinic radiation (e.g., UV), containing such polymer and by solvent removal of non-exposed regions.

摘要： Acid can be generated by exposing a superacid precursor to actinic radiation effective to generate superacid from the superacid precursor and heating the superacid in admixture with a secondary acid generator capable of undergoing thermal decomposition to produce a secondary acid. The superacid catalyzes decomposition of the secondary acid generator, thus increasing the quantity of strong acid present in the medium. The resultant secondary acid can be used to effect a color change in an acid-sensitive material, so providing an imaging process.

摘要： Hydroquinones form stable hydrogen-bonded complexes with N,N,N',N'-tetrasubstituted diamides of aromatic dicarboxylic acids in which two carboxyl groups are arranged para to one another on the same phenyl ring. These complexes are useful in rendering the hydroquinones more water-dispersible to assist their incorporation into photographic products. Also, the diamides may be incorporated into photographic products to reduce or eliminate various problems associated with hydroquinones, including migration of hydroquinones within the product during storage and the discoloration of images on storage due to oxidation of hydroquinone present in an image-receiving element of the photographic product.
