Abstract: Aqueous silver-containing composition is designed for use as an antimicrobial agent on fibers and fabrics. This composition includes silver halide particles, gelatin, and an additive that includes an N-heterocyclic acid having a pKa of from about 4 to about 9. The additive improves the redispersibility and shelf-life of the composition.

Abstract: A method for testing for presence of silver metal or silver salt antimicrobial agents on a surface of substrate, comprising a) contacting the substrate with a dye solution, wherein the dye solution comprises a dye selected to provide a detectable differential color change in the dye solution contacted substrate for a substrate having silver metal or silver salt on a surface thereof relative to a substrate not having silver metal or silver salt on a surface thereof, and b) detecting a presence or absence of the differential color change in the dye solution contacted substrate.

Abstract: This invention relates to a color silver halide photographic element comprising gelatin, a support bearing at least one dye image forming unit selected from a dye image forming unit comprising at least one red sensitive silver halide emulsion layer having associated therewith a dye-forming coupler, a dye image forming unit comprising at least one green sensitive silver halide emulsion layer having associated therewith a dye-forming coupler, and a dye image forming unit comprising at least one blue sensitive silver halide emulsion layer having associated therewith a dye-forming coupler; and a polymer represented by Formula 1.

Abstract: Disclosed is a color film comprising (1) a support layer, (2) a light sensitive layer, and (3) a water permeable color filter array (CFA) layer comprising a continuous phase transparent binder containing a random distribution of colored transparent beads, said beads comprising a water-immiscible synthetic polymer or copolymer.

Abstract: Color photographic elements can be processed with an acidic periodate bleaching composition that also includes chloride ions as a rehalogenating agent.

Abstract: Color photographic elements are processed with an acidic periodate bleaching composition that may also include chloride ions as a rehalogenating agent. Bleaching is carried out after color development is stopped with an acidic stop bath. The processing method provides relatively rapid bleaching without physical defects such as blistering or vesiculation.

Abstract: Color photographic elements are processed with a highly acidic periodate bleaching solution including a rehalogenating agent and a strong acid. Bleaching is carried out after color development without any intervening processing steps, such as an acidic prebath. The processing method provides rapid bleaching without physical defects such as blistering or vesiculation, and minimizes the formation of Dmin.

Abstract: This invention provides an accelerator for peracid bleaches used for bleaching silver halide photographic elements. The accelerator is a complex of ferric (Fe III) ion and a 2-pyridinecarboxylic acid or a 2,6-pyridinecarboxylic acid. The accelerator may be contained in the bleaching solution, a solution preceding the bleaching solution or in the photographic elements themselves.

Abstract: An aggregated-Group Ib metal colloid is prepared, which may be used to form stable color-differentiated images, by the selective application of thermal energy thereto. The metal aggregates, when exposed to thermal energy, revert either to the unaggregated metal or to an aggregate of lesser dimension. This change induces a color change in the material, which is clearly visible against those areas not so exposed. The metal aggregates, when dispersed in a polymeric matrix, are stable in the absence of heat.
