Photographic assemblage comprising a silver halide photographic element sealed in a closed vessel

A multilayer silver halide color photographic element comprises a support having coated thereon a silver antihalation layer, an interlayer, at least two red-sensitive silver halide emulsion layers, at least two green-sensitive silver halide emulsion layers a yellow filter layer, and at least two blue-sensitive silver halide emulsion layers, wherein the interlayer provided between the silver antihalation layer and the red-sensitive silver halide emulsion layer closest to the support contains a bleach accelerator releasing compound, and the silver antihalation layer contains a water-soluble organic thiol. The invention provides reduction in residual silver levels and backside turbidity after processing, without deleteriously affecting sensitometric properties of the photographic element.

Silver halide color photographic element having improved bleachability

Light-sensitive silver halide photographic element comprising a support bearing at least a light-sensitive silver halide emulsion layer and at least a protective layer being further away from the support than every silver halide emulsion layer, said protective layer containing a gelatin having a viscosity lower than 20 milliPascal per seconds in 10 weight % aqueous solution at 40.degree. C., said gelatin being hardened with a carbamoyl pyridinium salt compound having the following formula: ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different, each represents an alkyl group, an aryl group or an aralkyl group, or R.sub.1 and R.sub.2, together, constitute the atoms required to form a heterocyclic ring with the nitrogen atom to which they are bonded, R.sub.3 represents hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a carbamoyl group, or a ureido group, and R.sub.4 represents an alkylene group or a single chemical bond between the pyridinium nucleus and the --SO.sub.3 -- group.

Hardened silver halide photographic elements

Adjacency effects of a color photographic material may be increased by dividing a light-sensitive silver halide emulsion layer into three emulsion layers sensitive to the same spectral region of the visible light, the uppermost silver halide emulsion layer of which has the highest sensitivity and the lowermost silver halide emulsion layer has the lowest sensitivity, wherein the maximum color density of the uppermost silver halide emulsion layer, after color development, is lower than 0.60 and the maximum color density of both the intermediate and lowermost silver halide emulsion layers, after color development, are each higher than 0.60.
