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:
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:
Incorporating a crown ether-alkali metal complex cation of an enolate anion of an aldehyde having at least one electron withdrawing group in the alpha (α) position, provides thermally developable materials with imaging properties that have little change with changes in humidity. Both photothermographic and thermographic materials are provided, and particularly photothermographic materials having lower silver coverage.
摘要:
A photothermographic emulsion is prepared by chemically sensitizing silver halide grains formed by oxidative decomposition of a diphenylphosphine sulfide compound on or around the silver halide grains. This procedure uses a unique sequence of steps and provides increased photographic speed and manufacturing reproducibility.
摘要:
Photothermographic materials are designed with increased photospeed by chemical sensitizing the photosensitive silver halide grains with a combination of compounds. A first chemical sensitizer is a specific gold(III)-containing compound and a second chemical sensitizer is a sulfur-containing compound that is a diphenylphosphine sulfide. The molar ratio of the gold(III)-containing compound to the sulfur-containing compound is at least 1:1.
摘要:
A photothermographic emulsion is prepared by chemically sensitizing silver halide grains by oxidative decomposition of an organic sulfur-containing compound on or around the silver halide grains. This procedure uses a unique sequence of steps and provides increased photographic speed and manufacturing reproducibility. The resulting photothermographic emulsion can be used to prepare photothermographic materials.
摘要:
Thermally developable materials including photothermographic and thermographic materials have a buried conductive backside layer comprising one or more binder polymers in which are dispersed each of at least two types of conductive materials: (1) nanoparticles of one or more conductive metal compounds, and (2) one or more organic solvent soluble inorganic alkali metal salt antistatic compounds. These buried conductive backside coatings provide conductivity that is affected minimally by humidity.
