ABSTRACT:
A silver halide color reversal photosensitive material comprising a blue-sensitive emulsion layer unit containing a yellow color-forming coupler, a green-sensitive emulsion layer unit containing a magenta color-forming coupler and a red-sensitive emulsion layer unit containing a cyan color-forming coupler, on a transparent support, wherein the material includes at least one interimage effect-donating layer substantially forms no image; the wavelength, λrmax, at which the maximum sensitivity of the spectral sensitivity distribution of the red-sensitive layer unit is given, satisfies the relation: 620 nm≦λrmax≦680 nm; and the sensitivities of the red-sensitive layer unit satisfy the following relationships: Sr(610) is ⅕ of Sr(λrmax) or more; Sr(680) is 1/10 of Sr(λrmax) or more; and/or Sr(690) is 1/50 of Sr(λrmax) or more wherein Sr(610), Sr(680) and Sr(690) are the sensitivities of the red-sensitive unit at 610 nm, 680 nm and 690 nm, respectively, and Sr(λrmax) is the maximum sensitivity at λrmax.
