摘要:
A novel class of heterocyclic polymers and copolymers containing the 2-imidazolin-5-one ring structure is described. These polymers are prepared by reaction of bisazlactones and diamines, with or without suitable condensation monomers; the resultant polyamides are then thermally cyclodehydrated in the presence of a catalyst to produce the imidazolinone-containing polymers. Many of the poly(imidazolinones) are water soluble and therefore find utility in various aspects of water treatment, or in paper or fabric sizing.
摘要:
A pre-adhesive composition is described comprising an acid-functional (meth)acrylate copolymer and an aziridine crosslinking agent, which when crosslinked provides a pressure-sensitive adhesive and pressure-sensitive adhesive articles.
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.

Incorporating a sulfonyldiphenol compound into photothermographic materials improves Raw Stock Keeping and post-processing “hot-dark” print stability especially under harsh environmental conditions such as high temperature.
摘要:
Non-photosensitive direct thermographic materials comprise a reducing agent that is a catechol borate 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.
摘要:
Black-and-white, aqueous-based, silver halide-containing photothermographic materials have increased stability both prior to use and after imaging with the incorporation of at least 0.005 g/m2 of a tetrafluoroborate salt.

摘要:
Thermally developable materials for thermography or photothermography have imaging layers on one or both sides of the support. Buried conductive underlayers are disposed under these imaging layers on one or both sides of the support, and these conductive underlayers include conductive metal oxide(s) and optionally a smectite clay or lithium salt.
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.
