Abstract: 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/m2 of retained silver halide, and subsequently laser ablation marking the film to selectively ablate portions of the image forming units from the support.

Abstract: A gap measurement device includes a first roller and a second roller. The first roller and the second roller define a gap which varies due to thermal expansion and contraction of the rollers. A first optical probe measures a first distance to the first roller and generates a first-distance signal indicative of the first distance. A second optical probe measures a second distance to the second roller and generates a second-distance signal indicative of the second distance. An electronics module generates a gap-width signal indicative of the gap based on the first-distance signal and the second-distance signal. The invention can also measure roller velocity, roller runout, roller registration, and the thickness of liquid on a roller.

Abstract: Thermally processable imaging elements in which the image is formed by imagewise heating or by imagewise exposure to light followed by uniform heating are provided with both a backing layer and an electroconductive layer to reduce static electricity effects and improve conveyance through processing equipment. The backing layer is an outermost layer and is located on the side of the support opposite to the imaging layer whereas the electroconductive layer is an inner layer and can be disposed on either side of the support.

Abstract: Photographic support materials are comprised of a conventional support, such as polyester film, cellulose acetate film or resin-coated paper, having thereon an antistatic layer comprising vanadium pentoxide and an overlying barrier layer comprised of a latex polymer having hydrophilic functionality. The barrier layer provides excellent adhesion between the antistatic layer and overlying layers, such as silver halide emulsion layers or curl control layers, and also prevents unwanted diffusion of the vanadium pentoxide; whereby the combination of antistatic and barrier layers serves to impart a high level of permanent antistatic protection.

Abstract: A dispersion consisting essentially of magnetic particles, a dialkylester of phthalic acid which functions as a dispersing medium, and optionally, a dispersing agent is particularly useful as a precursor to a composition suitable for casting onto a cellulose acid ester support film to form a transparent magnetic recording layer for use in photographic films. The dispersion provides magnetic recording layers exhibiting fewer particle agglomerations and reduced light scattering and photographic prints prepared from films containing such magnetic layers exhibit virtually no increase in graininess attributable to the magnetic recording layer.

Abstract: Latex compositions comprising core-shell polymer particles are disclosed. The core has a glass transition temperature greater than 70.degree. C. The shell has a glass transition temperature of from about 25.degree. to 60.degree. C. The compositions form coalesced coatings that are resistant to ferrotyping.

Abstract: A coating composition useful in forming conductive layers comprises a conductive, water-dispersible, particulate polymer and a crosslinkable latex binder. The crosslinkable latex has a first glass transition temperature before crosslinking of substantially less than 50.degree. C. and a second glass transition temperature after crosslinking and coalescing of substantially greater than 50.degree. C. wherein the first and second glass transition temperatures differ by more than 4.degree. C. The coating composition can be coated on a variety of supports to produce conductive elements. The coating compositions are particularly useful in forming photographic elements which are resistant to the buildup of static charge and ferrotyping.
