SILVER HALIDE PHOTOGRAPHIC LIGHT-SENSITIVE MATERIAL

摘要

A silver halide photographic material is disclosed. The material comprises a support and at least one silver halide emulsion layer formed thereon, in which said emulsion layer or other layer contains a compound represented by formula (I) (I) wherein X represents an atomic group capable of releasing (Time)tPUG by undergoing an oxidation-reduction reaction with CA=CR1-CR2)nCB; CA and CB each represents a carbon atom; n represents an integer of 0, 1, 2, or 3; R1 and R2 each a hydrogen atom or a group substitutable for a hydrogen atom; EWG represents an electron withdrawing group having a Hammett's sigma para value greater than 0.3; -Time)tPUG represents a group bonded to CB through an oxygen atom thereof; Time represents a timing group; t represents 0 or 1; and PUG represents a photographically useful group.
