Abstract
A photothermographic material comprising: a transparent support; and a photosensitive layer comprising a photosensitive silver halide, a non-photosensitive organic silver salt, a thermal developer and a binder, wherein the photosensitive silver halide comprises silver iodide in a ratio of 5% by mole or more, the non-photosensitive organic silver salt comprises silver behenate in a ratio of 30% by mole or more and less than 80% by mole, and the binder has a glass transition temperature of 45° C. or more.
Claims9
A process for forming an image, the process comprising:
- exposing the photothermographic material to a light having a peak intensity at a wavelength of from 350 nm to 440 nm and an illuminance of 1 mW/mm2 or more;
- and
- subjecting the material to a thermal development after the exposing, wherein the photothermographic material comprises a transparent support;
- and
- a photosensitive layer comprising a photosensitive silver halide, a non-photosensitive organic silver salt, a thermal developer and a binder,
- wherein the photosensitive silver halide comprises silver iodide in a ratio of 5% by mole or more,
- the non-photosensitive organic silver salt comprises silver behenate in a ratio of 30% by mole or more and less than 80% by mole, and
- the binder has a glass transition temperature of 45° C. or more.
