发明名称 Silver halide color photographic materials containing combinations of magenta couplers and sensitizing dyes
摘要 A silver halide color photographic material comprising a support having on one side thereof at least one silver halide emulsion layer corresponding to each of the colors cyan, magenta, and yellow in which each of the colors cyan, magenta and yellow, respectively, are formed, wherein the layer which forms a magenta color is a green sensitive layer comprising (A) at least one coupler represented by formula (I) or formula (II) below <IMAGE> Formula (I) <IMAGE> Formula (II) wherein R1, R2, R'2 and X are as defined in the above specification and (B) silver halide grains which have been spectrally sensitized in such a way that they have a peak sensitivity between 540 nm and 555 nm by at least one spectrally sensitizing dye represented by the formulae (A), (B) and (C) below <IMAGE> (A) <IMAGE> (B) <IMAGE> (C) wherein W1, W2, V1, V2, V3, V4, V5, V6, R21, R22, R23, R24, R25, R26, R27, R28, R29, Y, X1, X2, X3 and the subscripts, l, m, n, o, p, q, r, s and t are defined as in the above specification, with the proviso that at least one of R21 and R22; at least one of R23, R24 and R25; or at least one of R26, R27, R28 and R29 represents an alkyl group or an aralkyl group which contains a sulfo group or a salt thereof a carboxyl group or a salt thereof, or a hydroxyl group provided that the speed at the spectral sensitivity peak wavelength of the green sensitive layer is twice or more of the speed at 500 nm.
