| 摘要 |
A photothermographic material of the present invention has a support and an image-forming layer disposed thereon, and the image-forming layer contains a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent and a binder. The binder contains a polymer formed by copolymerization of monomers including 10 to 70% by mass of a monomer represented by the following formula (M): CH2=CR<01>-CR<02>=CH2 wherein R<01 >represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a halogen atom, or a cyano group; R<02 >represents an alkyl group having 1 to 6 carbon atoms, a halogen atom, or a cyano group; and where R<01 >and R<02 >are never both simultaneously a hydrogen atom. The image-forming layer preferably contains an antifoggant of an organic polyhalogen compound.
