    摘要： Thermally developable materials such as thermographic and photothermographic materials include a co-precipitate comprising first and second organic silver salts, the first organic silver salt comprising a silver salt of a nitrogen-containing heterocyclic compound containing an imino group, and the second organic silver salt comprising a silver salt of a mercaptotriazole. The first organic silver salt can be used in the imaging process as a source of reducible silver ions, and the second organic silver salt can be a source of a toning agent. The co-precipitate can be prepared using double-jet precipitation techniques to provide an aqueous dispersion that can be used in imaging formulations.

    摘要： Thermally developable materials such as thermographic and photothermographic materials include a novel non-photosensitive source of reducible silver ions that are predominantly provided as rod-shaped particles of silver salt of a nitrogen-containing heterocyclic compound containing an imino group. The rod-shaped particles have an average aspect ratio of at least 3:1 and a width index for particle diameter of 1.25 or less, and provide improved imaging properties. These particles can be prepared using double jet precipitation procedures in which vAg is kept constant at a value of equal to or greater than −50 mV.

    摘要： High-speed black-and-white photothermographic materials can be imaged in any suitable fashion using ultraviolet, visible, infrared, or X-radiation. They can have one or more thermally developable imaging layers on either or both sides of the support and can be imaged with or without a phosphor intensifying screen in an imaging assembly. The photothermographic emulsions and materials have a net Dmin less than 0.25, and require less than 1 erg/cm2 to achieve a density of 1.00 above net Dmin.

    摘要： High-speed aqueous-based black-and-white photothermographic materials are imageable in any suitable fashion using ultraviolet, visible, infrared, or X-radiation. They can have one or more thermally developable imaging layers on either or both sides of the support and can be imaged with or without a phosphor intensifying screen in an imaging assembly. The photothermographic emulsions and materials have a net Dmin less than 0.25, and require less than 1 erg/cm2 to achieve a density of 1.00 above net Dmin. The imaging layers include hydrophilic binders or water-dispersible latex polymer binders and chemically and spectrally sensitized photosensitive silver halide grains.
