ABSTRACT:
A photographic silver halide photosensitive material is provided comprising a substantially water-insoluble basic metal compound and a water-soluble salt of the same metal ion as the basic metal compound which inhibits dissolution of the basic metal compound. An image is formed by combining the photosensitive material with a complexing compound in the presence of water and causing complexing reaction of the basic metal compound and the complexing compound to occur, increasing the pH of the system.
