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: 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 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.
