A method for processing and laser ablation marking an imagewise exposed motion picture photographic film element which comprises a support having on a front side thereof one or more image-forming units comprising at least one light-sensitive silver halide emulsion layer is described, comprising processing the film to provide a developed photographic image with at least 100 mg/m of retained silver halide, and subsequently laser ablation marking the film to selectively ablate portions of the image forming units from the support.

Method of processing motion picture print film to provide improved laser subtitling performance, and processed motion picture print film

A photosensitive material includes silver iodide produced by decomposing a solid electrolyte of the formula MA,g,having an ionic conductivity of >0.001 ohm,cm,in an organic solvent, where M is a monovalent cation. The photosensitive material further includes a sensitizing agent selected from the group consisting of residual MAg,I,, MAg,I,, and mixtures of residual MAg,I,, and MAg,I,.

Silver iodide-containing photosensitive material and photothermographic element formed therefrom

This invention comprises a photothermographic element comprising a support bearing an imaging layer comprising:

Photothermographic elements

Time and temperature integrating devices for providing a visually observable indication of cumulative thermal exposure are disclosed comprising (a) a substrate having thereon a thermally sensitive image-forming area comprising a combination of (i) an organic silver salt oxidizing agent and (ii) a reducing agent for the organic silver salt oxidizing agent, and (b) indicating indicia in association with the image forming area for indicating when the device has been exposed to a predetermined cumulative thermal exposure. In accordance with further embodiments of the invention, a process of applying such a device to a perishable product, and a perishable product having such a device applied directly thereto or to packaging thereof, are also disclosed. Time-temperature indicators in accordance with the invention undergo readily detectable changes can be easily optimized to match various rates of time-temperature dependent cumulative changes desired to be monitored for various products.

A process of preparing a photothermographic composition of enhanced photosensitivity is disclosed comprised of (a) precipitating light-sensitive silver halide grains in the presence of a non-aqueous polymeric peptizer and (b) then combining the silver halide grains with an oxidation-reduction image-forming combination comprised of an organic silver compound and a reducing agent for the silver organic compound. Light-sensitivity of the silver halide grains is enhanced by, prior to step (b), sensitizing the silver halide grains with a gold sensitizer dissolved in an aqueous medium.

Process of preparing a photothermographic composition of enhanced

A photothermographic composition of enhanced photosensitivity is disclosed prepared by a process of (a) precipitating light-sensitive silver halide grains in the presence of a non-aqueous polymeric peptizer and (b) then combining the silver halide grains with a non-aqueous polymeric vehicle containing an oxidation-reduction image-forming combination comprised of an organic silver compound and a reducing agent for the organic silver compound. Light-sensitivity of the silver halide grains is enhanced by, prior to step (b), sensitizing the silver halide grains with a 1,1,3,3-tetra-substituted thiourea or selenourea having an acid dissociation constant of less than 7.0, the thiourea or selenourea being dissolved in an aqueous medium.
