Silver halide photographic light-sensitive material
摘要:
Disclosed is a silver halide color photographic light-sensitive material including at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer, and at least one blue-sensitive silver halide emulsion layer on a support, and having an ISO sensitivity of 640 or more, wherein the material exhibits a color saturation evaluation value &eegr;, represented by equation (I) below, of −15 dB or more. &eegr;=10 log(1/VT) [VT=(⅙)×((62−Y1)2+(62−Y2)2+(62−Y3)2+(62−Y4)2+(62−Y5)2+(62−Y6)2)]  (I) In Formula (I), each of Y1 to Y6 is a value obtained by exposing 12 colors of a Macbeth color chart with six exposure amounts, from −1 under to +4 over, measuring the saturation of each resultant color, and averaging the data (chroma values) for a corresponding exposure amount.
