Abstract

1,203,757. Stabilizers for photographic silver halide emulsions. MINNESOTA MINING & MFG. CO. Dec.7, 1967, [Dec.8, 1966], No.55114/66. Heading G2C. [Also in Division C2] Silver halide photographic emulsions are stabilized by 4-hydroxy-5-iodo-1:3:3a:7- tetra-azaindenes by addition of the compounds, either to the emulsion as a whole, or to a particular layer of the emulsion, as this then stabilizes the adjacent layers of the emulsion by diffusion. Examples are given of the inclusion of the stabilizing compounds in silver iodebromide photographic emulsions.
