The negative materials of this invention for silver complex diffusion transfer process provide silver images high in density and improved in stability on image receiving materials. Said negative materials have the following characteristics:

Materials for silver complex diffusion transfer process

A photographic element having a photographic layer such as silver halide emulsion layer, protective layer, intermediate layer, subcoat layer, diffusion transfer image-receiving layer, antihalation layer and backing layer, can be improved in the adhesion between the layer and support, little curling on drying, and flexibility of the layer, by incorporating into the photographic layer a conversion mixture of a polyvinyl alcohol having a saponification degree of 96% or more and an ethylene-maleic anhydride copolymer.

Photographic element

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.

Multilayer silver halide color photographic material

Printing characteristics of a lithographic printing plate material using the silver complex diffusion transfer process are markedly improved by including in layer which contains nuclei for physical development or a layer adjacent thereto at least one member selected from the group consisting of polyfunctional synthetic polymers containing a functional group having an affinity to said nuclei and a functional group providing hydrophilic property and developing agents for silver halide.
