    摘要: Positive-acting photothermographic elements suitable for use in graphic arts and medical imaging comprising a photosensitive medium comprising a reducible silver source, a photo-acid generator, a binder and a reducing system for silver ion comprising a reducing agent for silver ion in which exposure of the element to actinic radiation causes the production of acidic species in the exposed regions which inhibit reduction of the silver source by the reducing system.

    摘要: Hot melt adhesives are provided that have improved heat resistance. The adhesives comprise a metallocene polyolefin, an amorphous α-olefin polymer, a tackifier and a functional polyolefin. The functional polyolefin is used in an amount sufficient to increase the heat resistance. A preferred functional polyolefin is a maleated polyolefin such as maleated polypropylene. A preferred tackifier is a hydrogenated hydrocarbon tackifier.
