摘要:
Incorporating a combination of phenolic reducing agents provides thermally developable materials with improved silver efficiency and hot-dark print stability without loss in other sensitometric properties. Both photothermographic and thermographic materials are provided, and particularly photothermographic materials having lower silver coverage.
摘要:
Transparent conductive films, articles made from them, and methods of making them are disclosed. Some transparent conductive films include flexible glass substrates and conductive layers containing metal nanoparticles. Others include at least one layer with cell walls that contain metal nanorods or conductive nanowires. Still others include a substrate with a coating disposed on it, with the coating including conductive components and photopolymers. Such films are useful in such articles as electronic displays, touch screens, and the like.
摘要:
Methods and compositions are disclosed and claimed for gravure printing of transparent conductive films comprising metal nanowires. Such films exhibiting low resistivity and superior coating uniformity may be used in electronic or optical articles.
摘要:
Mixtures of an alkyl vinyl ether/maleic anhydride copolymer or an alkylethylene/maleic anhydride copolymer with cellulose acetate provide protective overcoats for thermally developable materials. These protective overcoats exhibit good adhesion to the emulsion layer, are physically hard, and have good optical clarity while maintaining the sensitometric properties of the materials.
摘要:
Use of a combination of a trisphenol reducing agent (developer) and a substituted olefinic co-developer in photothermographic materials reduces their sensitivity to high humidity and improves processing latitude.
摘要:
Black-and-white, dry processable thermally developable materials have increased stability after imaging with the incorporation of at least 0.0001 mol/m2 of a thermal solvent having one or more >N—C(═O)— groups. Such thermally developable materials include both thermographic and photothermographic materials.

摘要:
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.
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.

摘要:
A negative-acting photothermographic element comprising a support bearing at least one heat-developable, photosensitive, image-forming photothermographic emulsion layer comprising:(a) an iridium doped, preferably iridium-doped core-shell, photosensitive silver halide grains, generally containing a total silver iodide content of less than 10 mole %, the shell having a second silver iodide content lower than the silver iodide content of the core;(b) a non-photosensitive, reducible source of silver;(c) a reducing agent for the non-photosensitive, reducible source of silver;(d) a binder; and(e) optionally at least one compound selected from the group consisting of: a halogen molecule; an organic haloamide; and hydrobromic acid salts of nitrogen-containing heterocyclic compounds which are further associated with a pair of bromine atoms.A process of forming photothermographic emulsions from iridium-doped silver halide grains by forming silver soaps in the presence of those grains is also described.
