| 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: n n n wherein, in the formula (1), V 1 to V 8 each independently represent hydrogen atom or a substituent, L represents a bridging group consisting of —CH(V 9 )— or —S—, and V 9 represents hydrogen atom or a substituent; n n n wherein, in the formula (2), R 1 and R 2 each independently represent hydrogen atom or a substituent, X 1 to X 3 each independently represent hydrogen atom or a substituent, provided that the substituents represented by X 1 to X 3 do not represent hydroxy group, and when the substituents represented by X 1 to X 3 are bonded to the phenol ring via nitrogen atoms, X 1 to X 3 represent a nitrogen-containing heterocyclic group or a group represented as —NH—C(═O)—R 4 where R 4 represents a substituent having 8-40 carbon atoms, or the substituents represented by R 1 , R 2 and X 1 to X 3 may be bound to each other to form a ring. There is provided a photothermographic material, in particular, for photographic art, more specifically, for scanners, image setters and so forth, that shows high sensitivity, high Dmax (maximum density) and low fog and can provide images suitable for photographic art. |
