Photothermographic materials with UV absorbing compounds

A black-and-white aqueous-based photo-thermographic material that comprises a transparent support having on both sides thereof:

• a) one or more thermally developable imaging layers each comprising a hydrophilic binder that is gelatin, a gelatin derivative, a poly(vinyl alcohol), or a cellulosic material, or is a water-dispersible polymeric latex, and in reactive association,
• a preformed photosensitive silver bromide, silver iodobromide, or a mixture thereof, provided predominantly as tabular grains, said tabular grains being spectrally sensitized to a predetermined wavelength within the predetermined range of wavelengths of from about 360 to about 420 nm,
• a non-photosensitive source of reducible silver ions that includes one or more organic silver salts at least one of which is a silver salt of benzotriazole,
• an ascorbic acid reducing agent for said non-photosensitive source of reducible silver ions, and
• b) optionally, an outermost protective layer disposed over said one or more thermally developable imaging layers,
• said material comprising an antihalation layer interposed between said one or more thermally developable imaging layers and said support, said antihalation layer comprising a UV-radiation absorbing compound, and
• said UV-radiation absorbing compound being one or more of the following compounds:

A black-and-white photothermographic material comprising a transparent support having on a frontside thereof,

• a) one or more frontside thermally developable imaging layers comprising a hydrophilic polymer binder or water-dispersible polymer latex binder, and in reactive association, a photosensitive silver halide that is spectrally sensitized to a predetermined wavelength within a predetermined range of wavelengths of from 360 to about 420 nm, a non-photosensitive source of reducible silver ions that includes a silver salt of a heterocyclic compound containing an imino group, an ascorbic acid or reductone reducing agent for said non-photosensitive source reducible silver ions, and
• said material comprising on the backside of said support, one or more backside thermally developable imaging layers comprising a hydrophilic polymer binder or a water-dispersible polymer latex binder, and in reactive association, a photosensitive silver halide that is spectrally sensitized to a predetermined wavelength within a predetermined range of wavelengths of from 360 to about 420 nm, a non-photosensitive source of reducible silver ions that includes a silver salt of a heterocyclic compound containing an imino group, and an ascorbic acid or reductone reducing agent for said non-photosensitive source reducible silver ions, and
• b) optionally, an outermost protective layer disposed over said one or more thermally developable imaging layers on either or both sides of said support, and
• wherein said one or more thermally developable imaging layers, or said one or more protective layers if present, on both sides of said support have the same or different composition, and
• said material further comprising an antihalation layer on both sides of said support, said antihalation layer being interposed between said support and said one or more thermally developable imaging layers on each side of said support,
• said antihalation layers on both sides of said support having the same or different composition and comprising a UV-radiation absorbing compound that absorbs radiation at a wavelength of less than 410 nm and is a hydroxyphenylbenzotriazole, hydroxyphenyltriazine, dibenzoylmethane, or mixture thereof.
