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:
Solid particle dispersions of certain ascorbic acid esters are prepared in the presence of at least 0.5 and less than 50 weight % of a particle growth modifier based on the weight of the ascorbic acid ester. The particle growth modifier is an alkyl carboxylic acid having from 8 to 22 carbon atoms, an alkyl ester of glycerol wherein the alkyl moiety has from 8 to 22 carbon atoms, or a stereoisomer of the ascorbic acid ester. The resulting aqueous solid particle dispersion can be used in various thermally developable materials including thermographic and photothermographic materials.
摘要:
High-speed black-and-white photothermographic materials can be imaged 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.

摘要:
Photothermographic imaging materials having increased photospeed are provided by certain selenium chemical sensitizers that are added during the formulation of a photothermographic emulsion. These selenium chemical sensitizers can be used alone or in combination with other sulfur, tellurium, or gold chemical sensitizers as well as with oxidatively decomposed sulfur-containing compounds.
摘要:
Chemical sensitization of silver halide photothermographic emulsions used in photothermographic elements, can be effected by the decomposition of sulfur containing compounds on or around the surface of the silver halide grains, usually under oxidizing conditions at elevated temperatures. Alignment of the sulfur containing compounds on the surface of the grains, can be accomplished with spectral sensitizing dyes and appears to be particularly effective in providing strong chemical sensitization effects.
摘要:
A polymerizable composition of polyurethane precursors is rapidly cured using energy-activated catalysts to provide polyurethanes. The polymerizable composition is comprised of polyisocyanates with polyols, fillers, coating aids, adjuvants, and a latent catalyst. Latent catalysts are ionic salts of organometallic complex cations. The cured polyurethanes are useful as abrasion resistant coatings, protective finishes such as furniture finishes and floor tiles, binders for magnetic media, adhesives, and have various applications in industries which use photoresist technologies such as graphic arts and electronics, and in the paint and ink industries.
