摘要:
Disclosed is a silver halide photographic material comprising a support having thereon a silver halide emulsion layer containing at least one nucleating agent represented by general formula (N-1) shown below. The silver halide photographic material contains at least one compound represented by general formula (Q-2) shown below in the above described silver halide emulsion layer and/or in a hydrophilic colloid layer adjacent thereto which does not contain a silver halide emulsion: ##STR1## The variable terms in the above formulas are defined in the specification. The silver halide photographic material is suitable for plate making and provides a high contrast image even when using a highly stable developing solution.
