  In a method for the immunological analysis of trace components by marking or labelling an antigen or antibody with a marker, an immune reaction is caused using an antigen or antibody marked with a fogging agent for silver halide, the labelled antigen or antibody is separated from the labelled antigen-antibody reaction product, the silver halide is developed in the presence of either one of the labelled antigen or antibody and the labelled antigen-antibody reaction product, and the density obtained is measured. The method is comparable to radioimmunoassay in having high reproductibility and sufficient sensitivity but does not involve any risk due to radiation.

  在一种用标记物标记或标示抗原或抗体从而对痕量成分进行免疫分析的方法中，使用卤化银雾剂标记的抗原或抗体引起免疫反应，将标记的抗原或抗体与标记的抗原-抗体反应产物分离，在标记的抗原或抗体和标记的抗原-抗体反应产物中任选一种存在的情况下显影卤化银，并测量所获得的密度。 该方法与放射免疫分析法相似，具有较高的重现性和足够的灵敏度，但不涉及任何辐射风险。

  A silver halide color photographic sensitive material is disclosed. The material is comprised of a substrate having a silver halide emulsion layer position thereon and a cyan dye forming coubler. The coupler is represented by the general formula (I): wherein R represents a substituted or nonsubstituted alkyl group, aryl group or heterocyclic group, X represents a group capable of releasing by an oxidative coupling reaction with a developing agent, and R' represents a substituted or nonsubstituted alkyl group or aryl group. The coupler of the invention can be easily dissolved in a high boiling point organic solvent and makes possible production of a light sensitive material having a high dye forming rate, high maximum color density and good fastness to light. Furthermore, the couplers prevent a large decrease in density when the bleaching solution utilized has a weak oxidation ability.

  本发明公开了一种卤化银彩色感光材料。 该材料由基底和青色染料形成耦合剂组成，基底上有卤化银乳剂层，耦合剂由通式（I）表示：其中 R 代表取代或未取代的烷基、芳基或杂环基，X 代表能与显影剂发生氧化偶联反应而释放的基团，R'代表取代或未取代的烷基或芳基。 本发明的耦合剂易于溶解在高沸点有机溶剂中，因此可以生产出染料形成率高、最大色密度高和耐光牢度好的感光材料。 此外，当使用的漂白溶液氧化能力较弱时，耦合剂可防止密度大幅下降。

  A silver halide color light-sensitive material is described, which is increased in sensitivity, is adapted to form an image of high contrast, or is accelerated in development by incorporating a small amount of a specific compound which imagewise releases a foggant or a development accelerator. This compound is represented by the formula: Coup-(TIME)n-FA (wherein Coup represents a coupler radical capable of undergoing a coupling reaction with an oxidized product of an aromatic primary amine developing agent; TIME represents a timing group which is eliminated from Coup by the coupling reaction and, thereafter, releases FA; n is 0 or 1; and FA represents a group which is eliminated from Coup in the coupling reaction when n is 0, whereas FA is released from TIME when n is 1. The FA has adsorption properties with respect to silver halide grains and also has a substantial fogging action with respect to the silver halide grains).

  描述了一种卤化银彩色感光材料，通过加入少量特定的化合物，在图像上释放出雾剂或显影加速剂，从而提高感光度，形成高对比度的图像，或加速显影。这种化合物的化学式如下Coup-(TIME)n-FA （其中 Coup 代表能与芳香族伯胺显影剂的氧化产物发生偶联反应的偶联基；TIME 代表通过偶联反应从 Coup 中消除并随后释放出 FA 的定时基团；n 为 0 或 1；FA 代表当 n 为 0 时在偶联反应中从 Coup 中消除的基团，而当 n 为 1 时从 TIME 中释放出 FA。）
