Photographic development adsorption

Figure 10 Photographic development mechanism. The reduction potential, E"(Ag+/Agn), ofthe latent image clusters, when in contact with a solution. Increases with the number of atoms n. Therefore a nuclearity threshold for developmen t is created by the redox poten tial of the developer E°(CP/D). Above the critical nuclearity n, the potential E°(Ag yAg ) is higher than E°(CA/D), and alternate electron transfer toward A g, and Ag adsorption on Err allows the cluster to grow autocatalytically. On the contrary, when l"(Ag, /Agg is lower than E°(E>-/D), corrosion ofsubcritical clusters takes place by oxidizing molecules, such as D or Ox [7],...

In this paper we have attempted to explore useful tools and unfinished business in the surface science of silver halide photographic systems. The sensitizing dye/AgBr system has been explored as a compliant model system for persons who might wish to carry out fundamental investigations in modes of adsorption and surface phase transitions. Many of the experimental and conceptual tools developed within the photographic industry are...
