    Abstract: A photosensitive element which comprises a support bearing a layer of negative-working tonable photoimaging composition comprising at least one organic polymeric binder (a), a photosensitizer (b) which generates an acid upon absorption of actinic radiation, and at least one compound taken from the group of ##STR1## as defined, binder (a) being plasticized by the decomposition product of either compound (c) or (d) or the combination thereof. The photosensitive element is useful in making color proofs.

    Abstract: Novel nitrobenzyl compounds are incorporated into a photographic emulsion or developer for controlled release of development/image modifier compounds. This occurs imagewise only after developer oxidation products have been formed in the course of the development process. For example, nitrobenzyl-masked phenylmercaptotetrazole (PMT), incorporated into a silver halide emulsion, reacts with developer oxidation products via an electron transfer mechanism to release the potent development restrainer PMT.

    Abstract translation: 将新的硝基苄基化合物引入照相乳剂或显影剂中以控制释放显影/图像改性剂化合物。 只有在显影剂氧化产物在显影过程中形成之后,才能成像。 例如,加入到卤化银乳剂中的硝基苄基掩蔽的苯基巯基四唑(PMT)通过电子传递机制与显影剂氧化产物反应以释放有效的显影抑制剂PMT。

    Abstract: A novel group of photographic sensitizing dyes is prepared by reacting the 5,7-dimethyl-1,2-benzoxathian-4-one-2,2-dioxide sultone nucleus with other organic compounds capable of forming merocyanine, oxonol or styryl dyes therewith. The resulting dyes are particularly useful in the sensitization of silver halide emulsions and provide excellent speed and low after-processing dye stain.

    Abstract: Novel heat-developable (photothermographic) films incorporate a silver alkyl sulfonate as a physical developer, and an organic base to neutralize acidity from the silver sulfonate. Preferably a heat-developable film is produced by coalescing a coating composition comprising a silver alkyl sulfonate, a silver halide emulsion as photocatalyst, a reducing agent, and an aqueous latex dispersion.
