摘要： A flowable, dry powder of particles of a developing composition are provided. The compositions may be either heat- or pressure-fixable and utilize from about 0.4 to 10 parts by weight of fluorinated carbon per 100 parts by weight of a thermoplastic binder and a magnetically responsive material. The fluorinated carbon has a degree of fluorination in the range of 10% to 100% and an average diameter below about 2 microns. The developing powder compositions possess improved flow humidity resistance and provide dramatically improved copy quality.

摘要： Certain poly(lactic acid) and poly(glycolic acid) polymers or copolymers, and certain carbonates, lactones, lactates, lactylates, lactides, glycolates, glycolylates, and glycolides have been found to stabilize thermal-dye-bleach constructions containing a dye in association with a thermally-generated-bleaching agent. Preferably, the thermally-generated-bleaching agent is a thermal-carbanion-generating agent such as a quaternary ammonium salt of a phenylsulfonylacetic acid or a thermal-nucleophile-generating agent such as an ammonium salt of a phenylsulfonylacetic acid. These materials have been found to be particularly effective when used in acutance and antihalation systems for photothermographic and photographic elements.
