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:
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.

Use of a combination of a trisphenol reducing agent (developer) and a substituted olefinic co-developer in photothermographic materials provides a number of improvements including a reduction of sensitivity to high humidity and improved processing latitude.
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:
Bis phenol reducing agents incorporating bicyclic and tricyclic substituents ortho to the hydroxyl groups on the aromatic rings have been found to provide photothermographic materials with improved silver efficiency and stability without significant loss in sensitometric properties.

摘要:
Photothermographic materials comprise heat-bleachable antihalation compositions in backside antihalation layers. These compositions comprise a hexaarybiimidazole and an oxonol dye that can be represented by the following Structure I: A1═L1—(L2═L3)p—(L4═L5)q—(L6═L7)r—A2−(M)k wherein A1 and A2 are the same or different activated methylene moieties, L1 through L7 independently represent a substituted or unsubstituted methine group, M represents a counterion, k is the number of M counterions necessary to provide neutral charge for Structure I, p, and q, are independently 0 or 1, and r is 0, 1, or 2. The antihalation composition is typically bleached when subjected to a temperature of at least 90° C. for at least 0.5 seconds.
