ABSTRACT:
A silver halide color photographic material comprises, a paper support having thereon a photographic constituent layer containing at least each one of a yellow coupler-containing layer, a magenta coupler-containing layer and a cyan coupler-containing layer, wherein that said magenta coupler is represented by formula (I), the weight ratio of a high boiling organic solvent in the same layer as said yellow coupler to said yellow coupler is 0.40 or less, and the pH value of the raw paper constituting said support is in the range of 5 to 9.
In a preferred embodiment, at least one of the yellow couplers is represented by formula (II). Another silver halide color photographic material is provided comprising on a paper support at least one yellow coupler-containing layer, one magenta coupler-containing layer and one cyan coupler-containing layer, wherein the material further comprises a magenta coupler represented by formula (I), a yellow coupler represented by formula (II) while and the pH value, of the raw paper constituting said support is in the range of 5 to 9. In addition, the weight ratio of a high boiling organic solvent in the same layer as said yellow coupler to said yellow coupler is preferably in the range of 0.2 to 0.38.
