摘要： Improved compounds and base precursors that undergo thermal decomposition are disclosed. Thermal base precursors, and in particular, a novel class of salts of arylsulfonylacetic acids as bleaching agents or promoting for photothermographic use are disclosed. Compositions employing these thermal base precursors are suitable for use in acutance and antihalation systems, bleachable filter dye materials, and in promoting unblocking of various components such as blocked developers, especially in photothermographic elements.

摘要： A novel photographic development inhibitor releasing coupler (A) comprises a coupler moiety bonded to at least one timing group that enables timing of release of a releasable development inhibitor moiety wherein the releasable development inhibitor moiety contains a --CH.sub.2 --Q group that is bonded directly to the inhibitor moiety and that is a group enabling, upon exposure and processing of a photographic element containing the coupler, reduced interlayer interimage effect without reduced image acutance. The coupler (A) is useful in a color photographic silver halide element and process.
