    • 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.
    • 含有至少一个光敏卤化银层的感光彩色照相卤化银材料,常规的扩散快速色彩耦合器与其相关联,并且可选地,其他层光敏感和光不敏感,其中材料中一种或多于一种的光敏银 卤化物层含有10-3-10mmol / mol卤化银的浓度,对应于下式(Z)nK(I)的化合物,其吸收并附着在卤化银颗粒上并与显影剂氧化反应 具有Keff> / = 103的有效反应速率常数的产物(EOP),其中式A是颗粒活性键合基团,Z表示二价中间体组分n为0或1,K表示形成有色或无色的基团 发现与显影剂氧化产物反应的反应产物具有改善的敏感性/颗粒度比。
