Abstract
A heat developable photosensitive material having on a support a non-photosensitive sliver salt, a photosensitive sliver halide, and a binder, which has an image forming layer containing the photosensitive sliver halide and comprises cyclic ketone or cyclic imine compound having a specific structure in combination with a nucleation agent on the side that the image forming layer is formed. This heat developable photosensitive material is an excellent high contrast sensitive material having a good stability.
Claims6
A heat developable photosensitive material having on a support an organic silver salt, a photosensitive silver halide, and a binder, which has an image forming layer containing the photosensitive silver halide and comprises at least one compound represented by Formula (S) and a nucleation agent on the side that the image forming layer is formed,
- in Formulas (S), X1 represents an oxygen atom or NH group;
- R1 and R2 each independently represents a hydrogen atom, an acyl group, a hydrocarbon group, or a carbamoyl group;
- at least one of R1 and R2 is a hydrogen atom where X1 is an oxygen atom;
- L1 represents ethylene, trimethylene, or a group having a structure below,
- wherein in the above formulae, hydrogen atoms may be substituted with a methyl group, an amino group, a ureido group, or a methylene group.
