Abstract (en)

A photosensitive image-forming element is provided comprising on a support at least one photosensitive layer containing silver halide crystals which are internally doped with a transition metal complex forming centers which are able to interact with photocharges, wherein said transition metal complex is represented by the general formula (1): ÄML6-nFnÜ<m-> as disclosed in the claims and in the description. A method for the preparation of a silver halide containing image-forming element, wherein the silver halide comprises said transition metal complex, has also been described.
