Abstract
A photographic assemblage comprising a silver halide photographic light-sensitive element comprising at least one sulfur and gold sensitized silver halide emulsion layer, said element comprising chlorinated s-triazine hardeners and photographically useful chemical compounds containing cyano groups, and a closed vessel in which the element is closed and stored at a constant relative humidity, is protected against HCN gas, which may evolve from photographic addenda included in the light-sensitive element to cause fog in the silver halide emulsion layers, by the addition of a palladium compound, in a silver halide emulsion layer and/or an adjacent layer thereto, as scavenger for HCN gas released from the element.
