Silver halide photographic materials with reducible brightening agent releaser

摘要

A silver halide photographic material having at least one silver halide emulsion layer on a support, comprising a compound of formula (I): PWR-(Time)t-FWA (I) in which PWR represents a group capable of releasing (Time)t-FWA upon reduction; FWA represents a group which functions as a brightening agent; Time represents a group capable of releasing FWA through a reaction which follows the release of (Time)t-FWA from PWR; and t represents an integer of 0 or 1.
