摘要： Dyes of formula (I) below are described. The dyes are useful as mid-green sensitizing dyes for photographic materials ##STR1## In the above formula, R1 and R3 are methyl or ethyl, at least one of R1 and R3 being methyl. R2 and R4 are substituted or unsubstituted C.sub.1 to C.sub.6 alkyl, provided that R2 and R4 are not both methyl. X1, X2, X3, and X4 are each independently methyl, methylthio, fluoro-substituted methyl or methylthio, or hydrogen, provided that at least one of X1 and X2 and at least one of X3 and X4 are not hydrogen. Y represents an ion as needed to balance the charge of the molecule. The dyes of formula (I) sensitize silver halide to light in the mid-green region of the spectrum.

摘要： An asymmetric radiographic element is disclosed comprised of a transparent film support, silver halide emulsion layer units of differing sensitometric characteristics coated on opposite sides of the film support, and a processing solution decolorizable means for reducing crossover to less than 10 percent. The radiographic element is positioned between intensifying screens and mounted in a cassette for exposure to X-radiation. A feature is included for ascertaining which of the emulsion layer units is positioned nearest a source of X-radiation during exposure.

摘要： A radiographic element is disclosed which exhibits high covering power, reduced crossover without emulsion desensitization, reduced wet pressure sensitivity, and can be fully processed in a rapid transport processor in less than 90 seconds. The radiographic is comprised of tabular grain emulsion layers on opposite sides of a transparent film support and processing solution decolorizable dye particles in hydrophilic colloid layers interposed between the emulsion layers and the support. Hydrophilic colloid on each side of the support is in the range of from 35 to 65 mg/dm.sup.2, with the interposed layer containing hydrophilic colloid in the amount of at least 10 mg/dm.sup.2.

摘要： A radiographic X-ray film comprising a polymer support. One or more silver halide emulsion layers are coated on each side of the support. A blue dye is contained within at least one of the polymer support or in an adjacent hydrophilic layer in a sufficient amount to result in a CIELAB measurement of L* less than or equal to 80 and b* less than or equal to −25. This configuration provides, after imaging and development, radiographic images having desirable visual contrast, image tone, b*, and image quality.

摘要： A reflective radiographic material is useful to provide images that can be viewed without a light box. This reflective radiographic material has a reflective support and a silver halide emulsion on one side of the support only. The material can be used with a single green- or blue-light emitting fluorescent intensifying screen as part of an imaging assembly. The reflective support enables the image in the radiographic material to be viewed without a light box and the speed of the material enables the use of low power X-radiation generating equipment.

摘要： Radiographic films exhibit improved visual performance because of the presence of certain colorants that provide more positive a* values without diminishing image tone (b*). Thus, the greenish tint the films may exhibit is reduced. These films provide desired sensitometric properties while they have reduced silver, hydrophilic polymer binder, and hardener coverage on both sides of a transparent support.
摘要翻译： 由于某些着色剂的存在提供更多的正a *值而不会降低图像色调（b *），因此放射照相胶片表现出改善的视觉性能。 因此，薄膜可能呈现的绿色色调减小。 这些膜在透明载体的两侧具有还原的银，亲水性聚合物粘合剂和硬化剂覆盖物时提供期望的感光特性。

摘要： A radiographic imaging assembly has first and second radiographic silver halide films in association with two fluorescent intensifying screens. Between one set of screen and film is a neutral density filter having a density of at least 0.3 to provide with improved exposure latitude for use in various exposure conditions and equipment. The neutral density filter comprises a transparent support having a hydrophilic neutral density filter layer disposed thereon, which layer includes sufficient silver metal, colloidal carbon, or exposed and processed silver halide in a hydrophilic binder to provide the desired density. The neutral density filter is laminated to one of the screens with its hydrophilic layer in contact with the screen.
