Definitions
- Photographic silver halide emulsions and photographic elements comprising said emulsions are improved against the detrimental effects of chemical and environmental fog by incorporating in said emulsions known metal chelates in effective concentrations.
- Said chelating metals include transition metals, actinides, lanthanides, beryllium, magnesium and the like. Enols of dehydroacetic acid, pyrithione and 1,3 diketone are preferred.
- Said chelated metals prepared by reacting a suitable salt of said metals with the desired chelating agents.
- Silver halide emulsions and elements described can be chemically sensitized, e.g., with noble metal sensitizers alone or in combination with sulfur or selenium sensitizers. They can contain spectral sensitizers, incorporated color-forming couplers, incorporated developing agents, other antifoggants, hardeners, plasticizers, coating aids, vinyl polymers, and other suitable photographic addenda such as described in U.S. Patent 3,297,446 of Dunn issued Jan. 10, 1967 (columns 4-9).
