Abstract
A silver salt photohermographic material is disclosed, comprising a support having provided thereon a light-sensitive layer containing light-sensitive silver halide, a light-insensitive organic silver salt and a binder, wherein the photohermographic material exhibits a gradation of 2.0 to 5.0 within the density region of 0.5 and 2.0 on a photographic characteristic curve obtained when the photothermographic material is subjected to exposure of 50 μJ/cm2 and thermal development at 124° C. for 16 sec.; the light-sensitive layer comprises lower and upper layers and a glass transition temperature of a binder contained in the lower layer being higher than that of a binder contained in the upper layer.
Claims14
A silver salt photothermographic material comprising a support having at least two light-sensitive layers provided on the support, wherein each of the light sensitive layers contains a light sensitive silver halide, a light-insensitive organic silver salt and a binder, wherein the photothermographic material exhibits a gradation of between 2.0 and 5.0 within the density region of between 0.5 and 2.0 on a photographic characteristic curve obtained when the photothermographic material is exposed to light of 50 μJ/cm2 and thermal development at 124° C. for about 16 seconds;
- the at least two light-sensitive layers comprise a lower layer and an upper layer, wherein the upper layer is disposed over the lower layer, and a glass transition temperature of a binder contained in the lower layer is higher than that of a binder contained in the upper layer.
