ABSTRACT:
A silver halide color photographic material comprising a support having thereon a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer, wherein the silver halide color photographic material contains at least one kind of pyrazoloazole type magenta coupler represented by the general formula (I) described below and the total coating amount of silver in the photographic material is 0.75 g/m.sup.2 or less. ##STR1## wherein R.sup.1 represents a hydrogen atom or a substituent; X represents a hydrogen atom or a group capable of being released upon a coupling reaction with an oxidation product of an aromatic primary amine developing agent; Za, Zb and Zc each represents a methine group, a substituted methine group, .dbd.N-- or --NH--, one of the Za-Zb bond and the Zb-Zc bond being a double bond and the other being a single bond; when the Zb-Zc bond is a carbon-carbon double bond, the Zb-Zc bond may be a part of a condensed aromatic ring; R.sup.1 or X may also form a polymer including a dimer or more; and when Za, Zb or Zc is a substituted methine group, the substituted methine group may form a polymer including a dimer or more.
The silver halide color photographic material provides color images having improved color reproducibility and preservability and is excellent in processing stability.
