A dry, activator sheet for a dry, thermal silver dye-bleach process, in the absence of a silver dye-bleach catalyst, comprises a support having thereon a nonvolatile, diffusible acid and a non-hydrolyzable polymeric vehicle having an effective pH up to 4.0 and a melting point lower than 200 DEG C. The activator sheet is useful to bleach a silver image containing a bleachable dye.
