摘要:
A photothermographic material is described, which comprises a support having provided on at least one side thereof a photosensitive silver halide, a photo-insensitive organic silver salt, a reducing agent for silver ion and a binder, wherein at least one layer constituting the photothermographic material comprises an oxazoline compound, by which sufficiently high image density is developed within practically feasible reaction time and temperature, and sufficiently suppressed background coloration is exhibited when stored for a prolonged period after development processing.
摘要:
A photothermographic element has on a support a photosensitive layer and a non-photosensitive layer containing (1) a base precursor, (2) a base-bleachable dye or a salt thereof, and (3) a binder. A constituent layer on the same side of the support as the non-photosensitive layer contains (4) a water-soluble polymer other than gelatin. The element is improved in coating surface quality and minimized in residual color.
