Abstract
A photothermographic material comprising on one side of a support a light-sensitive layer containing an organic silver salt, silver halide grains, a binder and a reducing agent and on the other side of the support a back coating layer, wherein a dry thickness of the light-sensitive layer is 9 to 16 μm; a centerline average roughness (Ra(B)) of an outermost surface of a back coating layer side is 100 to 150 nm; and the back coating layer contains a lubricant having a molecular weight of 550 to 10000.
Claims18
A photothermographic material comprising on one side of a support a light-sensitive layer containing an organic silver salt, silver halide grains, a binder and a reducing agent and on the other side of the support a back coating layer,
- wherein
- a dry thickness of the light-sensitive layer is 9 to 16 μm;
- a centerline average roughness (Ra(B)) of an outermost surface of a back coating layer side is 100 to 150 nm;
- and
- the back coating layer contains a lubricant having a molecular weight of 550 to 10000.
A photothermographic material comprising:
- on one side of a support, a light-sensitive layer containing an organic silver salt, silver halide grains, a binder and a reducing agent;
- and
- on the other side of the support, a back coating layer, and a subbing layer between the back coating layer and the support, the back coating layer and the subbing layer containing at least one of a polyester resin, an acryl resin and a polyurethane resin,
- wherein B>A is satisfied,
- wherein
- A represents a mass ratio of a total mass of the polyester resin, the acryl resin and the polyurethane resin contained in the back coating layer based on a total mass of a binder contained in the back coating layer;
- and
- B represents a mass ratio of a total mass of the polyester resin, the acryl resin and the polyurethane resin contained in the subbing layer based on a total mass of a binder contained in the subbing layer.
A photothermographic material comprising:
- on one side of a support, a light-sensitive layer containing an organic silver salt, silver halide grains, a binder and a reducing agent, and a light-insensitive layer provided on the light-sensitive layer;
- and
- on the other side of the support, a back coating layer, wherein
- a dry thickness of the light-sensitive layer is 9 to 16 μm;
- a centerline average roughness (Ra(E)) of an outermost surface of a light-sensitive layer side is 120 to 170 nm;
- and
- the light-insensitive layer or the back coating layer contains a lubricant having a molecular weight of 550 to 10000.
