Abstract
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.
