    • A color reversal photographic light-sensitive material is disclosed. The material is comprised of a support base having thereon a silver halide emulsion layer, an organic compound and colloid grains of a metal or metal sulfide or silver halide grains the surface of which is previously fogged. The silver halide emulsion layer includes fine grains of silver halide particles having a particle size of 0.3.mu. or less. The fine grain particles are present in the emulsion in an amount in the range of about 30% to about 95% based on the total number of silver halide grains in the emulsion. The silver halide emulsion also includes coarse grains having a particle size of more than 0.3.mu.. The organic compound has a solubility product constant of 10.sup.-14 or less when forming a salt with a silver ion. By utilizing the organic compound in combination with the particular fine grain silver halide particles it is possible to obtain a material which has improved tone reproduction properties in high exposure areas and also provide a material with a wide exposure lattitude.
    • 公开了一种彩色反转照相感光材料。 该材料由其上具有卤化银乳剂层,有机化合物和金属或金属硫化物的胶体颗粒或其表面预先起雾化的卤化银颗粒组成。 卤化银乳剂层包括粒径为0.3μm以下的卤化银颗粒细粒。 基于乳液中的卤化银颗粒总数,细颗粒存在于乳液中的量为约30%至约95%的范围内。 卤化银乳剂还包括粒度大于0.3μm的粗颗粒。 当与银离子形成盐时,有机化合物的溶解度积常数为10-14以下。 通过将有机化合物与特定的细粒卤化银颗粒结合使用,可以获得在高曝光区域中具有改善的色调再现性质的材料,并且还提供具有宽曝光度的材料。

    • A color reversal light-sensitive material comprising a support having coated thereon at least a pair of silver halide emulsion layers having mutually different color sensitivities and consisting of an emulsion having a high silver/coupler ratio and an emulsion having a low silver/coupler ratio, the former ratio being greater by a factor of at least 5 than the latter ratio, and the latter emulsion being incorporated with a compound containing recurring units represented by the following General Formula (I): ##STR1## the substituents being defined within the specification. By including the compound of the general formula (I) within the particular emulsion layer which is highly susceptible to changes in sensitivity and maximum density, it is possible to prevent deterioration in color balance which has been found to be due to variation in the concentration of potassium bromide.
