摘要:
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.
