Abstract
Disclosed is a photothermographic material comprising a support having disposed on a surface thereof, a non-photosensitive silver source, a photosensitive silver halide, and a reducing agent, and having disposed another surface thereof at least one non-photosensitive layer, wherein at least one of the non-photosensitive layers contains at least one type of gelatin having an isoelectric point of from 5.0 to 9.5; and a method for processing the photothermographic material.
Claims19
A photothermographic material comprising a support having disposed on a surface thereof, a non-photosensitive silver source, a photosensitive silver halide, and a reducing agent, and having disposed on another surface thereof at least one non-photosensitive layer, wherein at least one of the non-photosensitive layers contains at least one acid processed gelatin having an isoelectric point of from 5.5 to 8.0, a polymer latex, at least one dye that is decolored by heat development, and a base precursor.
A method for processing a photothermographic material comprising the steps of:
- (a) providing a photothermographic material comprising a support having disposed on a surface thereof, a non-photosensitive silver source, a photosensitive silver halide, and a reducing agent, and having disposed another surface thereof at least one non-photosensitive layer, wherein at least one of the non-photosensitive layers contains at least one acid processed gelatin having an isoelectric point of from 5.5 to 8.0, a polymer latex, at least one dye that is decolored by heat development, and a base precursor;
- and
- (b) imagewise exposing and then heat-developing the photothermographic material at a temperature of from 80° C. to 250° C. for a period of time of from 1 second to 60 seconds.
