A novel silver halide photographic element which contains a nondiffusible complex capable of releasing a diffusible, photographically useful material is disclosed. Said nondiffusible complex becomes active for ligand exchange upon reduction under alkalin conditions to release a diffusible, photographically useful material, said complex being represented by the following formula: ##STR1## wherein La is a quadridentate ligand group; Lb is a didentate ligand group; BALL is a ballast group; PHOTO is a photographically useful material group; Y is a counter ion; and r is the number of counter ions necessary for neutralizing the electric charge on the CO(III) complex.
本发明揭示了一种新型的银卤化物感光元素,其中包含一种能够释放可扩散的、具有摄影用途的物质的非扩散复合物。该非扩散复合物在碱性条件下还原后变得活性,以进行配体交换,释放可扩散的、具有摄影用途的物质,该复合物的化学式如下:##STR1## 其中,La是一个四配位配体基团;Lb是一个双配位配体基团;BALL是一个负荷基团;PHOTO是一个具有摄影用途的物质基团;Y是一个反离子;r是中和CO(III)复合物电荷所需的反离子数。
