Abstract

1,141,774. Rapid process silver halide materials. EASTMAN KODAK CO. May 26, 1966 [May 28, 1965], No.23531/66. Heading G2C. A rapid process photographic material comprises a support bearing a layer of an unhardened photographic silver halide emulsion optically sensitized with a water-soluble carbocyanine dye containing at least one end of the methine chain a benzoxazole or benzimidazole nucleus and whcih contains either in the emulsion layer or in a layer adjacent thereto a silver halide developing agent or a compound which liberates a developing agent under alkaline conditions. The emulsion may be an internal image, direct positive or photo-developable emulsion and contains hydroquinone, p-amino phenol and 3- pyrazolidone developers. The photographic materials may contain carbocyclic 1, 3-dione stabilizers, hardener precursors, and waterinsoluble inert solids as described in Specification 1,141,773.
