摘要:
Light sensitive color photographic silver halide material containing at least one light sensitive silver halide layer with which a conventional diffusion fast color coupler is associated and optionally other layers, both light sensitive and light insensitive, in which material the one or more than one light sensitive silver halide layer contains, at a concentration of 10.sup.-3 to 10 mmol/mol of silver halide, a compound corresponding to the following formulaA(Z).sub.n K (I)absorbed on and adhering to the silver halide grain and reacting with the developer oxidation product (EOP) with an effective reaction rate constant of K.sub.eff .gtoreq.10.sup.3, in which formulaA is a grain active bonding group,Z denotes a divalent intermediate membern is 0 or 1 andK denotes a group which forms a colored or uncolored reaction product in the reaction with the developer oxidation product,is found to have an improved sensitivity/graininess ratio.
