Abstract:
A photothermographic material comprising at least (a) a photosensitive silver halide, (b) a reducible silver salt, (c) a reducing agent represented by the following formula (1), (d) a binder, and (e) a phenol compound represented by the following formula (2) on the same side of a support: wherein, in the formula (1), V1 to V8 each independently represent hydrogen atom or a substituent, L represents a bridging group consisting of â€”CH(V9)â€” or â€”Sâ€”, and V9 represents hydrogen atom or a substituent; wherein, in the formula (2), R1 and R2 each independently represent hydrogen atom or a substituent, X1 to X3 each independently represent hydrogen atom or a substituent, provided that the substituents represented by X1 to X3 do not represent hydroxy group, and when the substituents represented by X1 to X3 are bonded to the phenol ring via nitrogen atoms, X1 to X3 represent a nitrogen-containing heterocyclic group or a group represented as â€”NHâ€”C(&boxH;O)â€”R4 where R4 represents a substituent having 8-40 carbon atoms, or the substituents represented by R1, R2 and X1 to X3 may be bound to each other to form a ring.
