A silver halide photographic light-sensitive material comprising a support and at least one silver halide emulsion layer wherein the silver halide photographic light-sensitive material contains at least one compound represented by the following general formula (I):
wherein COUP represents a coupler residue capable of undergoing a coupling reaction with an oxidation product of an aromatic primary amine developing agent; TIME represents a timing group which is released from COUP the coupling reaction and subsequently releases
represents a group capable of being released from COUP by the coupling reaction when n is 0, or a group capable of being released from TIME after TIME which has been released from COUP when n is 1, AD being adsorptive to silver halide particles; R represents an alkyl group, an aryl group or a heterocyclic group; R' and R", which may be the same or different, each represents a hydrogen atom or a substitutent; and -NHNHCOR may be directly connected to AD when AD is combined with the benzene ring to form a condensed ring system.
The'silver halide photographic light-sensitive material containing the compound represented by general formula (I) is improved in stability during storage and has a high sensitivity.
一种卤化银感光照相材料,包括一个支撑体和至少一个卤化银乳剂层,其中卤化银感光照相材料含有至少一种由下通式(I)表示的化合物:
其中 COUP 代表能与芳香族伯胺显影剂的氧化产物发生偶联反应的偶联剂残留物; TIME 代表在偶联反应中从 COUP 释放并随后释放的定时基团
R 代表烷基、芳基或杂环基;R'和 R "可以相同或不同,各自代表氢原子或取代基;当 AD 与苯环结合形成缩合环系时,-NHNHCOR 可直接与 AD 连接。
含有通式(I)所代表化合物的'卤化银感光材料'在贮存期间的稳定性得到改善,并具有高灵敏度。
