Silver halide photographic material and process for the development

Abstract

A silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer containing silver halide grains, wherein said silver halide grains have a silver chloride content of 30 mol% or more and contain (i) and iridium compound in an amount of 10.sup.-6 mol or less per mol of silver halide, (ii) at least one compound selected from the group consisting of iron, rhenium, ruthenium and osmium compounds in an amount of 10.sup.-3 mol or less per mol of silver halide, and (iii) (a) at least one compound selected from the group consisting of compounds represented by general formula (1-a), (1-b) and (1-c): ##STR1## wherein Z represents a C.sub.1-18 alkyl group, a C.sub.6-18 aryl group or a heterocyclic group; Y represents an atomic group required for the formation of a C.sub.6-18 aromatic ring or a heterocyclic group, said groups represented by Z or formed by Y may be substituted with at least one substituent; M represents a metallic atom or organic cation; and n represents an integer from 2 to 10, and/or (b) the silver halide grains have been chemically sensitized at a pH of 5.5 or less. A process for the development of the silver halide photographic material is also provided wherein processing is effected by an automatic developing machine in a total processing time of 20 to 60 seconds.
