description | 1,173,609. Photographic materials. GEVAERT-AGFA, N.V. Nov.17, 1967 [Dec. 12, 1966], No.55445/66. Heading G2C. Photographic silver halide materials are stabilized against fog by including in the silver halide layer or a water-permeable layer on the same side of the support as the silver halide layer, a water soluble compound of one of the formulae; wherein X 1 is a bivalent organic radical; X 2 is an aliphatic or aromatic bivalent group; M is H, alkali- or alkaline earth-metal, ammonium, guanidine, or an organic amine; and Y is an aliphatic, alicyclic, aromatic or heterocyclic radical, which may be substituted. A number of such compounds are listed. The emulsion may also contain a development accelerator, e.g. a polyoxyalkylene compound, sensitizers and other conventional stabilizers and additives. The compounds may be used as 0À1-30 mg per mole of silver halide, and may be added at any stage during the emulsion preparation. |
