Competitive penetration of two reacting species from solution into emulsion layers at a stage of photographic processing was studied by several methods reported previously.
In the case of formalin-sulfate prehardener for the process of coupler-in-developer type, penetration of OH- determined the progress in depth of harden0ed layer, because it penetrated slower than HCHO. The rate of diffusion-controlled development was generally more dependent on penetration rate of developing materials rather than that of 0H-. The rates of diffusion of couplers and other ingredients in processing solution were also determined.
The factors involved in diffusion-controlled process in photographic processing were discussed from the results.
