摘要： A process is disclosed of preparing an emulsion for photographic use comprised of silver halide grains and a gelatino-peptizer dispersing medium in which morphologically unstable tabular grains having {111} major faces account for greater than 50 percent of total grain projected area and contain at least 50 mole percent chloride, based on silver. The emulsion additionally contains at least one 2-hydroaminoazine adsorbed to and morphologically stabilizing the tabular grains. Protonation releases 2-hydroaminoazine from the tabular grain surfaces into the dispersing medium. Released 2-hydroaminoazine is replaced on the tabular grain surfaces by adsorption of a photographically useful benzimidazolium dye, thereby concurrently morphologically stabilizing the tabular grains and enhancing their photographic utility, and the released 2-hydroaminoazine is removed from the dispersing medium.

摘要： A process is disclosed of preparing an emulsion for photographic use comprising forming in the presence of an xanthinoid grain growth modifier an emulsion comprised of silver halide grains and a gelatino-peptizer dispersing medium in which morphologically unstable tabular grains having {111} major faces account for greater than 50 percent of total grain projected area and contain at least 50 mole percent chloride, based on silver. After the emulsion is formed, the pH of the emulsion is lowered to inactivate xanthinoid grain growth modifier, and the inactivated xanthinoid is replaced on the tabular grain surfaces by adsorption of a photographically useful compound chosen to contain at least one divalent sulfur atom, thereby concurrently morphologically stabilizing the tabular grains and enhancing their photographic utility.

摘要： Silver-free, aqueous-based direct thermographic materials are designed to have image tone with near neutral density. Without the use of organic silver salts containing reducible silver ions, the image is formed using a color developing agent precursor that releases a color developing agent when heated to a temperature of at least 80° C., a combination of cyan, yellow and magenta dye-forming color couplers that provide cyan, yellow, and magenta dyes, and a substituted or unsubstituted benzoquinone as an oxidizing agent. No silver metal or silver ions are purposely added to these materials. This combination of components provides a means for controlling image tone without reliance upon conventional toning agents.

摘要： Photographically useful radiation-sensitive high chloride {100} tabular grain emulsions containing iodide are disclosed. A high proportion of the {100} tabular grains contain crystal lattice dislocations extending inwardly from their peripheral edges. The dislocations are created by introducing elemental iodine into a high chloride {100} tabular grain emulsion, reducing the iodine to iodide, displacing chloride ions at the peripheral edges of the tabular grains with iodide ions, and then continuing growth of the high chloride {100} tabular grains. The dislocations in the peripheral and, particularly, corner regions of the tabular grains increase their sensitivity.

摘要： A process is disclosed of precipitating a high chloride {100} tabular grain photographic emulsion in which iodide incorporation in previously formed grain nuclei is relied upon to create the crystal lattice defects responsible for tabular grain growth. Undesirable dilution of the emulsion is avoided by replacing soluble iodide salt solution addition with iodine solution addition, allowing the volume of the iodine solution to be limited to less than 10 percent of the emulsion volume at the conclusion of tabular grain growth.
