Claims6
A photothermographic material comprising:
- a support;
- a photosensitive silver halide in an amount of 0.05 to 0.3 g/m2, in terms of coated silver per m2 of the photo sensitive material;
- a non-photosensitive organic silver salt in an amount of 0.5 to 2.0 g/m2;
- a heat developer;
- a binder;
- and
- a fluorine compound present in an emulsion surface protective layer and a back surface protective layer,
- wherein said fluorine compound is a compound represented by the following formula (B):
- wherein
- R1 and R2 independently are represented by the formula -La-Raf-W, wherein La represents a substituted or unsubstituted alkylene group, a substituted or unsubstituted alkyleneoxy group or a divalent group formed by combining these groups, Raf represents a perfluoroalkylene group having from 1 to 5 carbon atoms and W represents a hydrogen atom, a fluorine atom or an alkyl group;
- X represents -Lb-SO3M0, wherein M0 represents a hydrogen atom or a cation, and Lb represents a methylene group.
