Abstract: The invention describes silver halide packet emulsion grains or crystals that are conventionally precipitated using gelatin of a given isoelectric pH, surrounded by a layer of gelatin-grafted-polymer particles wherein the grafted gelatin has a different isoelectric pH and the said gelatin-grafted-polymer particles are optionally chemically bonded to the gelatin surrounding the silver halide microcrystals. Such packet emulsions can form the basis for a mixed-packet color photographic system.

Abstract: This invention describes the use of gelatin-grafted-polymer particles as peptizers for the preparation of silver halide photographic emulsions, whereby the gelatin-grafted-polymer particles remain attached to the AgX crystals after preparation of the emulsions. In an embodiment of this invention, the core polymer particles are loaded with photographically useful agents. When the photographic agent is a dye-forming coupler, multicolor mixed-packet systems can be constructed using the packet emulsions prepared in the manner of this invention.

Abstract: A method of preparing a photographic element containing a UV filter composition. In the method a UV absorbing polymer latex is prepared by emulsion polymerization, then loaded with a high boiling point organic solvent. The high boiling poing organic solvent has a boiling point at atmospheric pressure of at least 200.degree. C. The loaded polymer latex is then incorporated into a photographic element. Photographic elements containing UV polymer latexes particularly of a UV absorbing polymer containing benzotriazole monomers loaded with high boiling point organic solvents, are also provided.

Abstract: A process is disclosed for forming a dye image including the steps of:exposing a photographic element comprising a support bearing a light sensitive silver halide emulsion layer containing a polymeric color coupler compound capable of forming a heat transferable dye upon development, wherein the polymeric color coupler compound is of the formula:COUP-L-Bwherein COUP represents a coupler moiety capable of forming a heat transferable dye upon reaction of the moiety with an oxidation product of a color developer; L is a divalent linking group which is separated from COUP upon reaction of the coupler moiety with said oxidation product of a color developer; and B represents the polymeric backbone;developing said exposed element with a color developer solution to form a heat transferable dye image;heating said exposed, developed element to thereby transfer the dye image from the emulsion layer to a dye receiving layer, where said receiving layer is part of the photographic element or part of a separate dye receivin

Abstract: The polymerization and copolymerization of photographically useful vinyl monomers can be effected by dissolving such monomers in an isotropic oil-in-water microemulsion or in an isotropic water-in-oil microemulsion, each comprising monomers or comonomers, surfactants and/or cosurfactants, water, and optionally electrolytes. The microemulsion may be characterized as transparent or nearly transparent to the eye at 1% (w/w) or greater monomer, ultrafine in particle (droplet) size (typically in the range of 30 to 900 .ANG. in diameter), and spontaneously formed upon combining all the components with moderate stirring. The polymerization process is subsequently initiated with free radical initiators or with ultraviolet light. The components are chosen so that photographically useful polymers or photographically useful latexes are obtained, and said polymers or latexes may be coated in a photographic element.

Abstract: A method of forming color in a silver halide photographic element wherein the silver halide is sensitized with a dye involves reacting an oxidized developing agent with a phenol or naphthol cyan dye-forming coupler or an acylacetamide yellow dye-forming coupler in a sulfoxide coupler solvent. The sulfoxide solvent reduces sensitizer dye staining with the cyan or yellow dye-forming coupler in processed photographic materials (films and papers) due to retained sensitizing dye.

Abstract: A method of forming color in a silver halide photographic element wherein the silver halide is sensitized with a dye involves reacting an oxidized developing agent with a phenol or naphthol cyan dye-forming coupler or an acylacetamide yellow dye-forming coupler in a carbonamide coupler solvent. The carbonamide solvent reduces sensitizer dye staining with the cyan or yellow dye-forming coupler in processed photographic materials (films and papers) due to retained sensitizing dye.
