摘要： A novel silver halide color photographic material is provided comprising on a support at least one silver halide emulsion layer containing at least one of the compounds represented by formulae (I) to (III): wherein R11 represents or in which R13 represents an alkyl, aryl or heterocyclic group, and R14 and R15 each represents hydrogen, alkyl group or aryl group; R12 represents a substituent having a Hammett's substituent constant sigma p of 0.3 or less; n represents an integer 0 to 2, and when n is 2, the two R12's may be the same or different; B represents a group which releases PUG after being separated from a hydroquinone nucleus; PUG represents a development inhibitor; l represents an integer; and A and A' each represents hydrogen or a group capable of being removed by an alkali; R11 and R12, R11 and A or A', R12 and A or A', and two R12's may together form a ring; wherein Q represents an atomic group containing at least one hetero atom and is required for the formation of a heterocyclic group containing 5 or more members together with carbon atoms connected thereto; R represents a group capable of substituting on the hydroquinone nucleus; and B, PUG, l , A and A' are as defined above; wherein R31 represents an alkyl group containing two or more carbon atoms in which the carbon atom adjacent to the carbonyl group is not substituted by a hetero atom, a cycloalkyl group, an aryl group or a heterocyclic group; R32 and R33 each represents hydrogen or a substituent having a Hammett's substituent constant sigma p of 0.3 or less; and B, PUG, l , A and A' are as defined above. In a preferred embodiment, the compound represented by the general formula (III) is one represented by the general formula (IIIA): wherein R34 represents a substituent; PUG, A, A', B and l have the same meanings as defined in the general formula (III); and n' represents an integer 2 or more. The compound represented by the general formula (III) is also one represented by the general formula (IIIB): wherein R35 represents a substituent; A, A', B, PUG, and l have the same meanings as defined in formula (III); and m represents an integer 1 to 5, and when m is 2 ormore, the plurality of R35's may be the same or different.
