Silver halide photographic materials.

摘要

A silver halide photographic material is disclosed, which has at least one compound represented general formula (1): R-Y-NH-L-NHNH- @(Time)t-PUG (1) wherein R represents an aliphatic group, an aromatic group, or a heterocyclic group; both L and Time represent a divalent organic group; t represents 0 or 1; PUG represents a photographically useful group; Y represents -SO2-, -Y min -SO2-, or and Y min represents -O-, -NH-, or - @-. The material has a broad exposure latitude in line image-taking work and has a high resolving power in the work. It can form an ultrahard image having a high gamma value of 10 or more. The material may excellently reproduce a line original to form an ultrahard image having a high background density. It also has a broad exposure latitude in halftone dot image-taking work and can form a halftone dot image having ultrahigh contrast with high image quality.
