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

  A photographic element is described which contains a ballasted, bifunctional benzisoxazolone compound of the formula: wherein: R is alkyl or aryl; DEV is a silver halide developing agent; Ball is at least one organic ballasting radical of such molecular size and configuration as to render the compound nondiffusible in the photographic element during development in an alkaline processing composition; and n is a positive integer of 1 to 3. The compound may be employed in a negative-working, color image transfer element to release the developer upon processing. The remainder of the compound functions to scavenge oxidized developer.
