ABSTRACT:
A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, the silver halide color photographic material containing at least one pyrazoloazole type coupler represented by general formula (I) described below and at least one compound represented by general formula (II) described below. ##STR1## wherein R.sub.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 carbon-carbon double bond, the Zb-Zc bond may be a part of a condensed aromatic ring; R.sub.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; ##STR2## wherein R.sub.10 and R.sub.11, which may be the same or different, each represents an aliphatic group or an aromatic group; R.sub.12 and R.sub.13, which may be the same or different, each represents an aliphatic group, an aliphatic oxy group, an aromatic oxy group, and aliphatic thio group, an aromatic thio group, a nitrogen-containing heterocyclic group, an acylamino group, an aliphatic amino group or an aromatic amino group, or R.sub.12 and R.sub.13 may combine with each other to form a 5-membered or 6-membered hetero ring; and the aliphatic group or the aromatic group described above may be substituted.
The silver halide color photographic material provides magenta color images having improved fastness to light, and to humidity and heat.
