Abstract
A silver halide (AgX) color photosensitive material comprises, on a support, a AgX emulsion layer (BL) containing a yellow coupler and spectrally sensitized such that a spectral sensitivity region is 400 to 520 nm, a AgX emulsion layer (GL) containing a magenta coupler and spectrally sensitized such that a spectral sensitivity region is 470 to 600 nm, and a AgX emulsion layer (RL) containing a cyan coupler and spectrally sensitized such that a spectral sensitivity region is 540 to 700 nm, wherein barycentric sensitivity wavelength of a spectral sensitivity distribution of GL (&lgr;,), that of RL (&lgr;,), and that of BL (&lgr;,) are 520 to 580 nm, 590 to 650 nm, and 430 to 485 nm, respectively, the material further has an interlayer effect donor lay (DL) by which a barycentric wavelength (&lgr;,) of a magnitude distribution of an interlayer effect given to at least one RL at a wavelength of 500 to 600 nm satisfies 500 nm≦&lgr;,≦560 nm, and &lgr;,−&lgr;,≧5 nm, DL is placed closer to the support than GL, and the material further has a hydrophilic colloid layer containing at least one dye, in a dispersed state of solid fine grains, represented by formula (1): A1=L−Q or (2): A2=L−A3, wherein A1 A2 and A3 each represent an acidic nucleus, Q represents an aryl or aromatic heterocyclic group, and L represents a methine group, and wherein each of and L represents a methine group.
