摘要：
A photographic element including a support and first and second green-sensitive silver halide emulsion layers of different sensitivity, wherein the layer of higher sensitivity includes a two-equivalent magenta dye-forming coupler selected from the group consisting of a pyrazolone coupler having a structure according to formula I and a pyrazoloazole coupler having a structure according to formula II as set forth in the disclosure, and the layer of lower sensitivity includes a two-equivalent magenta dye-forming coupler selected from the group consisting of couplers defined by formulas I and II. The activity of the magenta dye-forming coupler present in the layer of lower sensitivity is less than the activity of the coupler present in the layer of higher sensitivity. The layers of higher and lower sensitivity do not comprise magenta couplers which are defined by the same formula.
摘要（中）：
一种照相元件，包括支持体和不同灵敏度的第一和第二感绿卤化银乳剂层，其中较高灵敏度的层包括两个等效的品红色染料形成成色剂，其选自具有下列结构的吡唑啉酮偶联剂： 式I和具有根据本公开内容的根据式II的结构的吡唑并吲唑偶联剂，并且较低灵敏度的层包括选自由式I和II定义的成色剂的两当量的品红色染料形成成色剂 。 存在于较低灵敏度层中的品红染料形成成色剂的活性小于在较高灵敏度层中存在的成色剂的活性。 较高和较低灵敏度的层不包括由相同公式定义的品红色成色剂。
