Photosensitive imaging material, the tabular silver (iodo) bromide crystals, which - with a metal complex ligands are doped, of the depth generated electron trap

摘要

A photosensitive image-forming element has been provided, comprising on a support at least one photosensitive layer containing silver halide crystals which are internally doped with a transition metal complex (more preferably a metal halide chalcogenic cyanate complex, further called a 'MHCC'-complex) forming a deep and permanent electron trap, wherein said transition metal complex satisfies the general formula (1) as disclosed in the claims and in the description.
