Abstract:

It is usually assumed that the reducing potential in the developing solution and the layer of film being developed is the same. However, data shows that in reality the developers composition in the layer can differ significantly from its composition in the solution. Experiments were set up to determine the speed of the developers penetration into the layer. It was concluded that the length of the induction period of development is linked to the pH of the developing solution and with a critical value of the developing agents oxidation-reduction potential.
