| titleOfInvention | Tabular grain silver halide emulsion with uniform epitaxial deposition |
| abstract | A process of sensitizing a tabular grain emulsion containing the steps of(i) providing a tabular grain host emulsion comprised of a dispersing medium and silver halide grains including tabular grains having {111} major faces and an aspect ratio of at least 2, which contain greater than 50 mole percent bromide, based on silver, and which account for greater than 50 percent of total grain projected area;(ii) adding a thiosulfonate compound of the following Formula I at the surface of the tabular grains of the host emulsion:where Z1 represents is a substituted or unsubsituted aliphatic, aromatic, or heterocyclic group, and Z2 represents a substituted or unsubsituted aliphatic, aromatic, or heterocyclic group, or a monovalent metal or organic cation, where Z1 and Z2 may combine together to form a ring structure or either of Z1 or Z2 may comprise a polymeric backbone wherein the thiosulfonate group may be repeated; and(iii) adding silver and halide ions, where the halide ions include at least, chloride ions, to the tabular grain host emulsion in an amount of from 0.5-7 mole percent based on total silver of the tabular grain host emulsion to precipitate silver halide protrusions forming epitaxial junctions with up to 50 percent of the surface area of the tabular grains essentially at only the corners of the tabular grains, the protrusions having an isomorphic face centered cubic crystal structure and including at least a 10 mole percent higher chloride ion concentration than the host tabular grains. |
