Abstract
A silver halide photographic material is disclosed which is comprised of a support having formed thereon a light-sensitive silver halide layer and a particular compound represented by the general formulae (I), (II) and (III). The compound is utilized in the photographic material in order to prevent the occurrence of contaminations which are caused by metals intermixed in the silver halide photographic materials during production, packaging, preservation and/or processing. The presence of such compounds also prevents the deterioration of photographic materials caused by metal ions existing in processing solutions and aids in preventing the reduction in the uniformity of processing.
