Abstract
1,269,071. Photographic silver halide colour material. EASTMAN KODAK CO. April 1, 1969 [April 1, 1968], No. 16867/69. Heading G2C. A photographic material comprises a support carrying at least two superposed silver halide layers sensitive to different spectral regions or separated by a filter layer whereby each layer is adapted to be separately imagewise exposed and the silver halide emulsion layer or layers not contiguous to the support contains a developmentinhibitor-releasing (DIR) coupler and has a finer grain silver halide emulsion than that of the emulsion contiguous to the support. All the silver halide emulsion layers may contain non-diffusing dye-forming couplers, the coupler in each layer forming a different colour dye from those in any of the other layers. The DIR coupler preferably releases a diffusible mercaptan development inhibitor. Many examples of couplers are given. The filter layer is preferably bleached during photographic processing and may be a layer of yellow Carey-Lea silver (EX7). There may be a hydrophilic colloid layer between each silver halide emulsion layer to delay diffusion of the photographic processing solutions. Preferably two silver halide emulsion layers are used – a silver chlorobromide emulsion containing the DIR coupler and a silver bromoiodide emulsion. One of these emulsions is preferably green-sensitized and the other is unsensitized, which embodiment yields a black and a coloured image (see EX2). These materials are useful in aerial reconnaissance.
