Patent ID: 7118849

Claim:
A black-and-white photothermographic material comprising a transparent support having on a frontside thereof, one or more frontside thermally developable imaging layers comprising a binder, and in reactive association, a photosensitive silver halide that is spectrally sensitized to a predetermined wavelength within a predetermined wavelength range of from 300 to about 450 nm, a non-photosensitive source of reducible silver ions, a reducing agent for said non-photosensitive reducible silver ions, and optionally an outermost protective layer disposed over said one or more thermally developable imaging layers, said material comprising on the backside of said support, one or more backside thermally developable imaging layers comprising binder, and in reactive association, a photosensitive silver halide that is spectrally sensitized to a predetermined wavelength within a predetermined wavelength range of from 300 to about 450 nm, a non-photosensitive source of reducible silver ions, a reducing agent for said non-photosensitive reducible silver ions, and optionally an outermost protective layer disposed over said one or more thermally developable imaging layers, said material further comprising an antihalation layer on at least one side of said support, said antihalation layer being interposed between said support and said one or more thermally developable imaging layers on at least one side of said support, said antihalation layers on at least one side of said support having the same or different composition and comprising a UV-radiation absorbing compound that absorbs UV-radiation at a wavelength of less than or equal to 410 nm.
