Abstract: Novel silver compounds can include a primary core of a photosensitive silver halide and a shell covering the primary core. This shell includes one or more non-photosensitive silver salts, each silver salt including an organic silver coordinating ligand. Other novel silver compounds are homogeneous silver salts of organic silver coordinating ligands throughout (non-core-shell). Still other silver compounds can include a primary core of a non-photosensitive metal salt and a shell covering the primary core. This shell includes one or more non-photosensitive silver salts, each silver salt including an organic silver coordinating ligand. These types of silver compounds can be used as sources of reducible silver ions in thermally developable imaging materials including thermographic and photothermographic materials.

Abstract: Nonlinear optical (NLO) compositions are disclosed which contain polar disulfone-functionalized molecules (PDFMs) incorporated in a polymeric material. when aligned noncentrosymmetrically in the polymeric material, the PDFMs generate a second-order NLO response. There is also disclosed: a method of preparing a NLO composition; novel PDFMs and novel polymers; and a new process for preparing PDFMs.

Abstract: A process for preparing polar disulfone-functionalized molecules, which process comprises performing one or more of the following reactions:(i) reacting a vinyl ether disulfone molecule with an activated aromatic molecule, an activated heterocyclic molecule, a dye base, or a dye olefin;(ii) reacting an enamine disulfone molecule with a dye base or a dye olefin; and(iii) reacting an alkenyl disulfone molecule having a vinylogous methyl or methylene group conjugatively located relative to the disulfone group with an aldehyde or an acetal derived from an aldehyde.

Abstract: Cyanine dyes, particularly indocyanine dyes, having at least 7 carbon atoms in the polymethine chain which may possess a fused cyclopentene or cyclohexene ring in the form of a tri-iodide salt exhibit a substantial reduction in the propensity to associate compared to dyes having the identical cation but different anion. The tri-iodide salts are particularly useful as sensitizers in organic photoconductor systems.

Abstract: Thermographic composition comprising a leuco dye, a nitrate salt, and, optionally, an acid and stabilizing compound. The leuco dye contains a phenazine nucleus with naphthoyl substitutents on the 10-position and, optionally on one or both of the 3- and 7-positions through an amino group.In their oxidized form, the leuco dyes of this invention provide access to a range of red and magenta colors which exhibit greater stability when subjected to light and temperatures characteristic of the stage of overhead projectors than that exhibited by previously available leuco dyes of this color range.
