ABSTRACT:
In color photographic sensitive materials comprising at least one direct reversal silver halide emulsion layer associated with a diffusible dye-releasing redox compound on a base, the improvement which comprises that at least one of a layer containing said redox compound or said direct reversal silver halide emulsion layer contains about 5 to 200 mg per 100 millimols silver in the emulsion layer of a compound represented by the general formula (I): ##STR1## wherein A.sub.1 and A.sub.2 each represents a hydrogen atom or a hydrolyzable group, P, Q and R which may be the same or different each represents a hydrogen atom, an alkyl group, an aryl group, an alkylthio group, an arylthio group, a hydroxyl group, a halogen atom, an alkoxy group, an aryloxy group, a heterocyclic group or an --S--Z.sup.2 group, Z.sup.1 and Z.sup.2 may be the same or different and each represents an unsaturated heterocyclic residue which is photographically inactive when bonded to the hydroquinone through the sulfur moiety, and --S--Z.sup.1 or --S--Z.sup.2 is an atomic group which when released by oxidation exhibits a development inhibiting function; at least one of P and Q is an alkylthio group or an arylthio group, and at least one of P, Q and R contains a ballast group.
