摘要:
Post-processing stabilizers for photothermographic, silver imaging media are disclosed. The stabilizers are represented by the following general formulae: ##STR1## wherein: R.sup.1, R.sup.2, and R.sup.3 are independently H, halogen, an alkyl group, an alkoxy group, a thioalkyl group, a cycloalkyl group, a perhalogenated alkyl group, or taken together form a cycloaliphatic group.Compounds of formula (I) may be used as stabilizer precursors in photothermographic silver imaging media to provide post-processing stability without significantly adversely affecting desired properties of the photothermographic material.

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:
1,3-Diaryl-substituted urea compounds have been found to function as post-processing stabilizers in photothermographic materials. These compounds can be presented by the following Structure (I): wherein R1 and R2 are the same or different substituted or unsubstituted aryl group.
摘要:
Thermally developable materials including photothermographic and thermographic materials having a buried conductive backside layer comprising one or more binder polymers, and an antistatic compound that is an organic solvent soluble alkali metal salt of any of a perfluorinated aliphatic carboxylic acid having 2 or 3 carbon atoms, a perfluorinated aliphatic sulfonate, or a tetrafluoroborate, provide antistatic coatings that exhibit little dependence on humidity.
摘要:
Non-photosensitive direct thermographic materials comprise a reducing agent that is a specific ortho-amino-phenol, para-amino-phenol, or hydroquinone compound. These compounds can reduce silver(I) ion to metallic silver to produce a dense black silver image under the short time and high temperature conditions that occur when using thermal print-heads during direct thermal printing. The materials are characterized by their calculated aqueous deprotonation and their calculated anion HOMO energies.
摘要:
Photothermographic materials contain one or more blocked aliphatic thiol compounds in an amount of at least 1 mg/m2 as stabilizers. These compounds have a calculated octanol-water partition coefficient (c log P value) of 2.0 or greater, and an N value equal to or greater than 6.5.

摘要:
Thermally developable photothermographic materials comprise a backside layer that includes a backside stabilizer to reduce fog formation in high humidity conditions, thereby providing improved shelf stability. Useful backside stabilizers are nitrogen-containing aromatic heterocyclic compounds. These backside stabilizers can be provided particularly in non-photosensitive compositions that include an antihalation composition.
