Abstract
A multilayer silver halide color photographic material submissive to rapid silver removal containing, in at least one layer, a salt of at least one compound selected from the group consisting of organic compounds containing sulfur such as, for example, mercaptotriazoles and the like and heterocyclic compounds containing no sulfur such as, for example, imidazole compounds and the like with at least one heavy metal ion such as, for example, ions of silver, zinc, cobalt and the like.
Claims8
