A silver halide photographic light-sensitive material is described having at least one light-sensitive silver halide emulsion layer on a base, wherein the improvement comprises that said light-sensitive silver halide emulsion layer or another hydrophilic colloid layer on said base contains a polyoxyethylene type surfactant and a complex salt of divalent or tetravalent palladium.

Silver halide photographic light-sensitive materials

A silver halide photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the light-sensitive silver halide emulsion layer or other layer is a hydrophilic colloid layer containing a polyoxyethylene surface active agent represented by general formula (I) or (II) described below, and a nitron compound selected from nitron, an inorganic acid salt thereof and an organic acid salt thereof. ##STR1## wherein R.sub.1, R.sub.2, R.sub.6 and R.sub.8, which may be the same or different, each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a halogen atom, a substituted or unsubstituted acyl group, a substituted or unsubstituted amido group, a substituted or unsubstituted sulfonamido group, a substituted or unsubstituted carbamoyl group or a substituted or unsubstituted sulfamoyl group; R.sub.5 and R.sub.7, which may be the same or different, each represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a halogen atom, a substituted or unsubstituted acyl group, a substituted or unsubstituted amido group, a substituted or unsubstituted sulfonamido group, a substituted or unsubstituted carbamoyl group or a substituted or unsubstituted sulfamoyl group, provided that R.sub.5 and R.sub.6 or R.sub.7 and R.sub.8 may combine to form a substituted or unsubstituted ring; R.sub.3 and R.sub.4 each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted .alpha.-furyl group, provided that R.sub.3 and R.sub.4 may combine to form a ring; n.sub.1, n.sub.2, n.sub.3 and m, which may be the same or different, each is an integer of from 2 to 50; and in general formula (II) the substituents represented by R.sub.5, R.sub.6, R.sub.7 and R.sub.8 on the two benzene rings may be bilaterally symmetrical or asymmetrical. The silver halide photographic light-sensitive material has an excellent antistatic property and development processing aptitude, along with excellent photographic properties and screen contamination properties. The antistatic properties of the material are not reduced with the passage of time.
