A silver halide color photoqraphic light-sensitive material having an excellent graininess, sharpness and color reproducibility, particularly of green colors including yellowish qreen and bluish qreen is disclosed. Among silver halide emulsion layers, the blue-sensitive layer is located furthest from a support and the outside thereof, has a non-light-sensitive layer. And the optical specifications of these two layers are as specified in the claims.

Preferably, the maximum sensitivity wavelength .lambda..sub.G of said green-sensitive layer is in the range of 530 nm.ltoreq..lambda..sub.G .ltoreq.560 nm and the sensitivity of said green-sensitive layer at the wavelength of 500 nm is not less than one-fourth of the sensitivity at SG.sub.max ; the maximum sensitivity wavelength .lambda..sub.R of said red-sensitive layer is in the range of 595 nm.ltoreq..lambda..sub.R .ltoreq.625 nm and the maximum sensitivity of red-sensitive layer in the range of 400 nm to 480 nm is not less than 1.5% of the sensitivity of blue-sensitive layer at .lambda..sub.B.

Color photographic light-sensitive material offering excellent hue

A silver halide color photographic material is described which is to be processed by a scheme including at least the step of development with a color developer having a pH of at least 11 wherein said material contains a specific pyrazoloazole based magenta coupler and a compound that react with the oxidized product of a color developing agent and which substantially lacks the ability to impart an image density. The color photographic material is improved in granularity and color reproduction and yet permits efficient desilvering.
