摘要：
The invention is directed to a color photothermographic film in which particles comprising an organic silver salt is treated with a passivating agent. In particular, the present invention involves passivating the organic silver salts with an organic adsorbate that blocks the surface of the organic silver salt or ligand, resulting in a reduction of speed loss. The invention is also directed to a method of making a photothermographic element to improve raw stock keeping.
