摘要： 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.
