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. |

DETAILED DESCRIPTION OF THE INVENTION The above alkyl group, alkylthio group and alkoxy group described for P, Q and R may be substituted or unsubstituted and preferably contain 1 to 20 carbon atoms in the alkyl moiety excluding substituents.
Examples of substituents for these groups include alkoxy groups, alkylamino groups, alkylthio groups (in which the alkyl moiety may be straight chain, branched chain or cyclic), carbonamido groups (including an alkylcarbonamido and an arylcarbonamido), sulfonamido groups (including an alkylsulfonamido and an arylsulfonamido), etc.
, having 1 to about 20 carbon atoms.
The above aryl group, arylthio group and aryloxy group described for P, Q and R may be substituted or unsubstituted.
The aryl moieties of these groups may be monocyclic and contain 6 to 20 carbon atoms.
Examples of substituents for these groups include alkoxy groups, alkylamino groups, carbonamido groups (including an alkylcarbonamido and an arylcarbonamido), sulfonamido groups (including an alkylsulfonamido and an arylsulfonamido), etc.
, having 1 to about 20 carbon atoms.
The above-described heterocyclic groups represented by P, Q and R may be unsaturated, condensed, or saturated and contain as hetero atoms one or more of a nitrogen, sulfur or oxygen atom, etc.
They are preferably 5-or 6-membered rings containing nitrogen atoms or sulfur atoms as hetero atoms.
Representative examples are pyrazole, indazole, triazole, benzotriazole rings, etc.
These rings may be substituted by alkyl groups (such as a methyl group, an ethyl group, etc.
), an alkoxy group, a carbonamido group (including an alkylcarbonamido and an arylcarbonamido) and a sulfonamido group (including an alkylsulfonamido and an arylsulfonamido).
At least one of P and Q is an alkylthio group or an arylthio group.
When the DIR compound having such a specific P and Q substituent is incorporated in a specific layer(s) in relation to the DRR compound, the above described effects are achieved.
The heterocyclic ring represented by Z
