A dry, activator sheet for a dry, thermal silver dye bleach process comprises a support having thereon a non-volatile, diffusible acid, a substituted heterocyclic thiazoline, oxazoline, imidazoline or imidazolidine silver halide complexing agent and a non-hydrolyzable polymer vehicle having an effective pH up to 6.0 and a melting point lower than 200 DEG C. The activating sheet is useful to bleach a silver image containing a bleachable dye.
