    摘要: A silver halide photographic light-sensitive material which comprises a support having thereon a light-sensitive silver halide emulsion layer, wherein the photographic light-sensitive material contains a blocked photographic agent therein represented by formula (I): ##STR1## wherein A represents a photographic agent moiety which is bonded to a blocking moiety through a hetero atom or a group which is bonded to a blocking moiety through a hetero atom and capable of releasing a photographic agent upon a subsequent reaction after the group is released; Y represents a hydrogen atom or a substituent; and Z represents an atomic group necessary to form a carbocyclic ring or a heterocyclic ring.The precursor of photographic agent is completely stable during the preservation of the photographic light-sensitive material and releases a photographic agent at a desired time upon the processing of the photographic light-sensitive material. The precursor also exhibits its function to a substantial degree over a wide range of pH.
