摘要： The present invention provides silver halide photographic materials containing a havel compound, which when reduced, releases a photographically useful group as triggered off by the cleavage of the nitrogen-oxygen single bond in the compound and which is represented by the following general formula (I)
wherein EAG represents a group which accepts an electron from a reducing substance; N and 0 each represents nitrogen atom and an oxygen atom, respectively; R' and R 2 each represents a substituent other than a hydrogen atom, and when R' or R 2 is bonded to -(Time)̵― t ― PUG, R' or R 2 is a mere bond or a substituent other than a hydrogen atom, and R' and R 2 may be bonded to each other to form a ring; Time represents a group for releasing PUG via the subsequent reaction as triggered off by the cleavage of the nitrogen-oxygen single bond in the compound of general formula (I); PUG represents a photographically useful group; t is an integer of 0 or 1; the full lines in the formula each mean a bond; and the dotted lines therein mean that at least one of the dotted lines is a bond. In particular, compounds of the following formula (II) and (III) are preferred among those of the formula (I):
wherein R 3 is bonded to the nitrogen atom or oxygen atom in the formula, and represents an atomic group necessary for the formation of a 3 to 8-membered mono-or fused-hetero ring;
wherein R 4 and R 5 each represents a mere bond, a hydrogen atm or a substituent group, and they may be . bonded to each other to form a saturated or unsaturated carbon ring or hetero ring; and X represents a divalent binding group.
