PROBLEM TO BE SOLVED: To provide a greatly improved fluorescence imaging forming element, displaying higher photographic sensitivity, higher contrast, and improved image discrimination. SOLUTION: The coupler chemistry comprises the combination of a developing agent that generates an oxidized form on reaction with exposed silver halide, together with a molecule capable of forming a stable reaction product, preferably a dye, by reaction with the oxidized form of the developer. This will have the effect of a sink for the oxidized developer formed during development. In a preferred embodiment, dye-forming chemistry is combined with fluorescent image formation to provide dramatic improvements in performance of a fluorescent system. COPYRIGHT: (C)2004,JPO
