    摘要: Aqueous ink jet ink compositions are used for ink jet printing colorless, colored or invisible images on receiver elements. These compositions contain a dispersion of an unsaturated natural oil and a water compatible polyurethane. The unsaturated oil dispersion is prepared from conventional surfactants or a polyurethane dispersing agent. The polyurethane is prepared from unsaturated polyol segments prepared from the unsaturated natural oils. The ink preparations are printed on media treated with agents such as metal ions known to catalyze crosslinking reactions in unsaturated oils. Such compositions are useful in various ink jet printing systems including drop on demand and continuous ink jet printing systems.

    摘要: A conductive pattern is formed in a polymeric layer that has (a) a reactive polymer comprising pendant tertiary alkyl ester groups, (b) a compound that provides an acid upon exposure to radiation, and (c) a crosslinking agent. The polymeric layer is patternwise exposed to radiation to provide a polymeric layer comprising non-exposed regions and exposed regions comprising a polymer comprising carboxylic acid groups. The exposed regions are contacted with electroless seed metal ions to form a pattern of electroless seed metal ions. This pattern of electroless seed metal ions can be contacted with a non-reducing reagent that reacts with the electroless seed metal ions to form an electroless seed metal compound that has a pKsp of less than 40. This bound electroless seed metal compound is then electrolessly plated with a suitable conductive metal.

    摘要: A process is disclosed of preparing a photographic emulsion comprised of high bromide silver halide tabular grains accounting for greater than 90 percent of total grain projected area. The grains exhibit a low level of size dispersity by reason of forming in the presence of a dispersing medium containing a polyalkylene oxide block copolymer surfactant a population of silver halide grain nuclei containing twin planes, the halide content of the grain nuclei consisting essentially of silver bromide, and growing the silver halide grain nuclei containing twin planes to form the tabular silver halide grains. Inadvertent variation in tabular grain sizes and thicknesses from one precipitation to the next are minimized by growing the silver halide grain nuclei at a pH in the range of from 3.0 to 8.0 and in the presence of at least a 0.01M concentration of a partially dissociated acid having a pKa that is within 2.5 units of the pH and that forms a silver salt more soluble than the silver halide incorporated in the grains.
