摘要： Photothermographic emulsions and materials that are highly sensitive to imaging radiation and that provide high contrast images are provided by making the emulsions with photosensitive silver halide grains that have been formed in the presence of a hydroxytetrazaindene or an N-heterocyclic compound comprising at least one mercapto group, such as a mercapto tetrazole. Such grains can then be chemically sensitized before or after mixing with an organic silver salt using a sulfur-, tellurium-containing, or gold-containing chemical sensitizing compound, or mixtures thereof.

摘要： Silver halide emulsions lack stability in that their properties vary over a period of time. Various stabilizers have been used to reduce the rate and degree of variation. The combination of uracils and nitroso-substituted phenols has been found to provide a synergistic stabilization of speed in silver halide emulsions. Other stabilizers may be combined with those two classes to further improve the stability of the emulsion.
