Abstract:
The present invention is a motion picture film which includes a support having, in order, on one side thereof an antihalation undercoat and at least one silver halide emulsion layer and having, in order, on the opposite side thereof an antistatic layer and a protective overcoat. The protective overcoat includes a polyurethane binder having a tensile elongation to break of at least 50% and a Young's modulus measured at a 2% elongation of at least 50000 lb/in.sup.2, and a topcoat farthest from the support. The topcoat is formed by the coating and subsequent drying of a coating composition comprising gelatin-grafted polyurethane comprising gelatin covalently bound to a polyurethane through a grafting agent, wherein the ratio of gelatin to polyurethane is from 1:10 to 2:1.
Abstract:
A simple and effective peroxide bleaching method includes the use of a bleaching solution including a peroxide bleaching agent and chloride ion in an amount of at least 0.35 mol/l. An organic phosphonic acid or tertiary aminocarboxylic acid can also be present for stability. The method is useful for bleaching high silver bromide color negative photographic films containing at least 80 mol % silver bromide and from 0.5 to 5 mol % silver iodide in at least one silver halide emulsion.
Abstract:
Motion picture prints made with the dye transfer, or imbibition (IB) process have a reputation for superior image quality and permanence. The process offers unique control over the dynamic range and color gamut of the prints. This invention provides for the insertion of a digital link in the traditional path of the image between the original record and the dye transfer print. The digital link provides digital means for alerting the color information in the image thereby simplifying the chemistry of the process, and enabling the manufacture of dye prints as a theatrical release medium for images originated either electronically or on film.
Abstract:
Leader strip for motion picture films is described which is composed of a substrate of cellulose acetate or polyester, a gum-removing layer comprising an organic binder selected from the group consisting of cellulose esters, polyurethanes, polyacrylonitrile, copolymers of acrylonitrile and vinylidene chloride, and epoxy resins, a gum-shearing agent of finely divided polymeric particles, said agent being bonded by the organic binder to the substrate, said gum-shearing agent being a member selected from the group consisting of polyesters, polyamides, polyimides and polyolefins, said polymeric particles having a size less than about five mils.
Abstract:
Holograms of moving subjects or of motion picture frames are recorded on a photosensitive carrier. When the carrier is moved with the holograms through coherent light, real images of the subject are formed which are reproduced for viewing.
Abstract:
A film image recorded on an initial movie film is converted into a television video signal which is thereafter converted into another film image and recorded an another movie film. The initial movie film includes an identification film part formed in the front end part of the initial movie film and includes first and second identifying patterns which are respectively arranged in alternating frames. By adjusting the timing of the conversion of the television video signal to the other film image in accordance with the image from the identification film part obtained during this conversion, the film image recorded on the other movie film is made to correspond to the film image recorded on the initial movie film.
