Photothermographic material
View Patent ↗Provided is a photothermographic material comprising, on a support, at least a non-photosensitive layer, and an image forming layer comprising at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder, wherein a content of the binder in the image forming layer is from approximately 55.6% to approximately 47.6% by mass ratio. A photothermographic material capable of rapid thermal development and having excellent film quality is provided.
1. A photothermographic material comprising, on a support, at least a non-photosensitive layer, and an image forming layer comprising at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder, wherein
a content of the binder in the image forming layer is from approximately 55.6% to approximately 47.6% by mass ratio to a total solid content in the image forming layer.
2. The photothermographic material according to claim 1 , wherein the content of the binder in the image forming layer is from approximately 54.1% to approximately 48.1% by mass ratio to the total solid content in the image forming layer.
3. The photothermographic material according to claim 1 , wherein the content of the binder in the image forming layer is from approximately 51.3% to approximately 48.8% by mass ratio to the total solid content in the image forming layer.
4. The photothermographic material according to claim 1 , wherein the non-photosensitive layer contains binder containing hydrophobic polymer in an amount of approximately 50% by weight or more.
5. The photothermographic material according to claim 1 , wherein the non-photosensitive layer contains binder containing hydrophobic polymer in an amount of approximately 90% by weight or more.
6. The photothermographic material according to claim 1 , wherein the non-photosensitive layer is provided on the side farther from the support than the image forming layer and adjacent to the image forming layer.
7. The photothermographic material according to claim 6 , further comprising a non-photosensitive outermost layer provided on the side of the support having the image forming layer and the non-photosensitive layer.
8. The photothermographic material according to claim 7 , further comprising a non-photosensitive intermediate layer provided between the image forming layer and the non-photosensitive layer.
