Processes for preparing such silver ion sequester and release agent material are also described comprising combining in an aqueous medium a crystalline or amorphous metal hydrogen phosphate ion exchange host material of the formula M(HPO4)2.nH2O with less than 2 molar equivalents of silver ions relative to the amount of ion exchange host material such that silver ions are exchanged for protons in the host material, and adding a base compound to the aqueous medium to achieve a pH of at least 4.4 and sequester at least 95% of the combined silver ions into the host material. Further described are photographic elements comprising a support bearing one or more hydrophilic colloid layers including at least one photographic silver halide emulsion layer, wherein one or more layers contain such a silver ion sequester and release agent which sequesters silver ions prior to photographic processing and releases silver ions upon exposure to photographic processing solutions.

    摘要: A radiation sensitive imaging element is described comprising a support bearing one or more hydrophilic colloid layers, wherein a photographically useful compound is incorporated into at least one hydrophilic colloid layer in the form of a self-assembled composition comprising a substantially homogeneous and ordered array of the photographically useful compound and silver and halide atoms, wherein the average minimum distance from each Ag atom in the composition to an atom of the photographically useful compound in the composition is less than 50 Å. In a particular embodiment, the self-assembled composition is of the general unit cell formula AgaXb(PUC*)c.nH2O where X represents halogen atoms selected from Cl, Br, and I or any combination thereof, and PUC* is a photographically useful compound containing at least one positively charged onium ion group; and wherein a is an integer from 1-10 and b is an integer from 2-18, with the proviso b is greater than a, and the silver and halide atoms form silver halide sublattice structures having a net negative charge; c is an integer such that the onium ion group containing photographically useful compound forms a positively-charged sublattice which stabilizes the negatively charged silver halide sublattice, wherein charge neutrality for the composition is upheld; and n is any number from 0 to 10. The invention provides novel materials and a method of incorporating active chemistry compounds such as developers or development inhibitors directly into a photographic imaging element. The invention further provide materials, and a method for preparing materials, comprising silver halide co-crystallized with photographic useful compound molecules thereby creating a unique crystal lattice. The invention described herein provides materials in which active chemistry and silver halide are present together in an ordered array, or crystal lattice, separated by distances measured on the atomic scale (i.e., in angstroms (Å), where 1 Å=10−4 &mgr;m).

    摘要: A color photographic element is disclosed comprised of a transparent film support and, coated on the support, a red recording layer unit containing the latent image forming silver halide grains in a plurality of emulsion layers with the latent image forming silver halide grains of maximum sensitivity being the first red recording emulsion layer to receive exposing radiation and containing randomly oriented red light scattering silver halide grains free of adsorbed spectral sensitizing dye. An optional layer coated beneath first layer contains tabular silver halide grains to reflect red light. Improvements in imaging speed with improvements or relatively low losses in image sharpness are realized.
