Abstract
A film formed by stretching and heat-fixing a melt of a polyester and a polyolefin which has a melting temperature lower than that of the polyester is employed as a support for a diffusive transfer-type photothermographic material, which prevents processing unevenness and white spot.
Claims5
A diffusive transfer-type photothermographic material which comprises (i) a light-sensitive element comprising a light-sensitive silver halide and a binder provided on a first support and (ii) an image-fixing element provided on a second support, wherein said light-sensitive element and said image-fixing element are capable of forming an image by being attached to each other with a small amount of solvent under heat in the presence of a base, a base precursor or a mixture thereof, after or simultaneous imagewise exposure of said light-sensitive element,
- wherein at least one of the first support and the second support is a film which comprises a stretched and heat-fixed melt comprising a polyester and a polyolefin having a melting temperature lower than that of the polyester.
