A laminate donor element can be used to transfer a composite of a metal grid and an electronically conductive polymer to a receiver sheet for use in various devices. The laminate donor element has a donor substrate, a metal grid that is disposed over only portions of the donor substrate, leaving portions of the substrate uncovered by the metal grid, and an electronically conductive polymer that covers the portions of the donor substrate that are uncovered by the metal grid. The composite of metal grid and electronically conductive polymer exhibits a peel force of less than or equal to 40 g/cm for separation from the donor substrate at room temperature. The resulting article has a substrate on which a reverse composite of the metal grid and electronically conductive polymer is disposed, which article can be incorporated into various devices.

Black-and-white, aqueous-based, silver halide-containing photothermographic materials have increased stability after imaging with the incorporation of at least 0.0002 mol/mof a halogen-substituted tetraazaindene compound.

Halogen substituted tetraazaindene compounds in photothermographic materials

Aqueous-based photothermographic materials comprise a hydrophilic binder, preformed silver halides, an organic silver salt, a reducing agent composition, and one or more benzothiazolium, benzoselenazolium, or benzotellurazolium salts as antifoggants. These photothermographic materials can be used in combination with phosphor intensifying screens for radiographic imaging.

Black-and-white aqueous photothermographic materials

The present disclosure relates to aqueous dispersions of silver (carboxylate-azine toner) particles wherein the azine content of the particles is from about 0.01 to 10% by weight relative to silver carboxylate. The carboxylates are typically silver salts of long chain fatty acids and the azine toners are the compounds that function as development accelerators and toning agents such as phthalazine. These silver (carboxylate-azine) particles can be used to formulate imaging forming compositions that are useful in aqueous thermographic or photothermographic imaging elements.

Silver-(carboxylate-azine toner) particles for photothermographic and thermographic imaging

The invention relates to a method of forming a silver halide emulsion comprising forming a silver chloride emulsion, adding spectral sensitizing dye, sulfur, and gold sulfide to said emulsion, heating said emulsion to chemically and spectrally sensitize said emulsion, and cooling said emulsion.

Silver-(carboxylate-azine toner) particles for photothemographic and thermographic imaging

Aqueous-based thermally sensitive emulsions and imaging materials include two or more hindered phenol silver ion reducing agents in a non-crystalline reducing agent composition. Such compositions can be provided as evaporated dispersions and can be formulated in aqueous coating compositions to provide thermally developable materials such as thermographic and photothermographic materials.

Thermally developable emulsions and imaging materials containing mixture of silver ion reducing agents

A method of imaging employing sensitized high chloride silver halide emulsions which exhibit improved speed and high intensity reciprocity performance for use with short duration, high intensity exposure optical and digital exposure systems. The method comprising providing a photographic element comprising at least one high chloride silver halide emulsion layer, exposing said element utilizing a high intensity actinic radiation exposure for an exposure time of less than {fraction (1/100)} second, and developing said element to produce a photographic image, wherein the high chloride silver halide emulsion layer is comprised of silver halide emulsion grains containing at least 90 mole percent chloride, based on silver, obtained by providing a high chloride host emulsion, bringing a Lippmann emulsion comprising primarily fine silver bromide grains doped with iridium into contact with said high chloride host emulsion, and subsequently chemically sensitizing the high chloride emulsion.
