    摘要: Many photographic materials must be handled under special lighting conditions in order to prevent exposure of the material. The use of large concentrations of bleachable light absorbing layers over the photosensitive emulsion tends to leave an undesirable residual stain. The inclusion of a specific class of low intensity reciprocity failure inducers to silver halide emulsions enables the emulsions and their photographic articles to be safely handled under white light conditions.

    摘要: High contrast negative images are obtained by developing a silver halide photographic element, in the presence of a hydrazine compound, with an alkali aqueous developing solution which contains a combination of developing agent comprising hydroquinone or substituted hydroquinone and a superadditive developing agent and an antioxidant, wherein the developing solution has a pH lower than about 12 and wherein the silver halide photographic element comprises an emulsion layer including surface latent image negative type silver halide grains in reactive association with a contrast promoting agent, preferably a diarylcarbinol compound, more preferably a diarylmethanol compound in a quantity useful to increase contrast.

    摘要: A radiation-sensitive element for half tone color proofing adapted to be exposed by scanning with four independently modulated sources of radiation emitting at different wavelengths within the range 550 to 900 nm, the element comprising a substrate bearing at least four separate imaging media coated thereon, said imaging media including:(1) an imaging medium capable of forming a yellow image upon imagewise exposure and processing,(2) an imaging medium capable of forming a magenta image upon imagewise exposure and processing,(3) an imaging medium capable of forming a cyan image upon imagewise exposure and processing, and(4) an imaging medium capable of forming a black or a balancing black image upon imagewise exposure and processing,each imaging medium having a maximum spectral sensitivity at a wavelength different from that of the maximum sensitivity of the other imaging media such that after exposure and processing super-imposed yellow, magenta, cyan and black or balancing black images are formed, each image being attributable to the imagewise exposure of the respective source. Three layer elements of forming yellow, magenta and cyan images may be used for preparing half-tone full color images. Exposure apparatus comprising at least three independently modulated sources, preferably semi conductor sources emitting in the region of 550 to 900 nm may be used for imaging.

    摘要: An anti-copy film is disclosed. The film has a light transmissive imageable substrate having opposing first and second surfaces. Each surface has an image receptive coating. Complementary positive and negative images are disposed on the first and second surfaces such that an imaged area on the first surface is in registration with a non-imaged area on the second surface. The anti-copy film appears substantially opaque when viewed orthogonally to and appears partially transparent when viewed obliquely to either the first or second surfaces.
