ABSTRACT:
A silver halide photographic light-sensitive material is disclosed, which has excellent characteristics peculiar to pyrazoloazole type magenta couplers and yet good suitability to rapid processing, and shows improvement in the gradiation in respect of softening at the toe portion of characteristic curve thereof without impairment of the image preservability and other photographic properties. The photographic material comprises a support having thereon a silver halide emulsion layer containing a silver halide grain having a silver chloride content of not less than 90 mole %, a compound represented by the following Formula I, and a compound capable of deactivating the oxidized product of a color developing agent with a relative reaction rate of not less than 1.6; ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 each represent a substituent other than hydrogen atom, which may be the same as or different from each other; Z represents a group of non-metal atoms necessary for completing a heterocyclic ring which may have a substituent; X represents a hydrogen atom or a group capable of being split off upon reaction with the oxidized product of a color developing agent.
