摘要:
The present invention relates to a silver halide color reversal photographic material comprising photosensitive silver halide photographic layers in which the average silver chloride content of the photosensitive silver halide emulsions is less than 7.0 mol %, at least one emulsion layer of the photographic layers consists of two or more emulsions having different average grain diameters, and the emulsion layer and/or the adjacent intermediate layer contains at least one compound that can release a photographically useful agent by redox reaction with the oxidation product of a developing agent. The silver halide color reversal photographic material of the present invention has a color-reversed image improved in graininess and sensitivity.

摘要:
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.

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.
