ABSTRACT:
A silver halide color photographic material is disclosed. The material has improved developing characteristics which are obtained by containing both a substantially light-insensitive silver halide and at least one specific 3-pyrazolidone compound. The substantially light-insensitive silver halide includes a halogen composition consisting of 0 to 100 percent of bromide, 0 to 2 percent of iodine and the residual percent of chlorine, a mean grain size of 0.01 to 0.3.mu., and a coverage of 5 to 500 mg/m.sup.2. The 3-pyrazolidone compound has the following general formula (I): ##STR1## wherein X represents a hydrogen atom or an acetyl group; R represents an aryl group; and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents a hydrogen atom, an alkyl group or an aryl group, and they may be the same as or different from one another. The material can be developed at an increased speed and is not accompanied by undesirable photographic effects such as fogging.
