| abstract |
A silver halide photographic material is disclosed, which comprises a support having formed thereon at least one silver halide emulsion layer, wherein the silver halide photographic material contains, in the silver halide emulsion layer, other hydrophilic colloid layer(s), or both, a compound represented by formula (I) <IMAGE> (I) wherein EAG represents an electron accepting group, -SO2- represents a sulfonylene group; X represents an oxygen atom (-O-), a sulfur atom (-S-) or an atomic group (-N(R2)-) containing a nitrogen atom; the single bond between -SO2 and X being cleaved after EAG receives an electron, wherein R1 and R2 each represents a simple bond or a group other than a hydrogen atom; said R1, R2, EAG may be combined with each other to form a ring; (Time) represents a group capable of releasing a photographically useful group (PUG) upon the cleavage of the SO2-X bond; t represents 0 or 1; when said t is 0, (Time) represents a simple bond and X may be a part of PUG; the solid line represents a bond; the dotted lines show that at least one of them is bonded. |
