Abstract:
Acrylonitrile compounds are useful as co-developers when used in combination with hindered phenol developers to produce high contrast black-and-white photothermographic and thermographic elements.Acrylonitrile compounds are also useful as co-developers when used in combination with (i) hindered phenol developers, and (ii) trityl hydrazide and/or formyl-phenyl hydrazinc co-developers, to produce ultra-high contrast black-and-white photothermographic and thermographic elements.The photothermographic and thermographic elements may be used as a photomask in a process where there is a subsequent exposure of an ultraviolet or short wavelength visible radiation-sensitive imageable medium.
Abstract:
Photothermographic elements having improved post-processing stabilty are described. These elements comprise a support bearing at least one photosensitive, image-forming photothermographic-emulsion layer comprising:(a) a photosensitive silver halide;(b) a non-photosensitive, reducible silver source;(c) a reducing agent for said non-photosensitive, reducible silver source,(d) a binder; and(e) a compound capable of releasing a post-processing stabilizer having a nucleus of the formula: ##STR1## wherein: A represents any monovalent group for which the corresponding compound AH functions as a post-processing stabilizer.
Abstract:
Novel compounds derived from azlactones act as precursors for photographically active groups. The active groups are released at an appropriate time in the use of photographic and photothermographic systems.
Abstract:
The post-processing stability of silver halide photothermographic emulsions is enhanced by the presence of stabilizing amounts of certain azlactones.
Abstract:
Transparent ink-jet recording films, compositions, and methods are disclosed. Such films exhibit superior resistance to ink-transfer when printed to high optical densities, which is desirable for medical imaging applications.
Abstract:
Transparent ink-jet recording films, compositions, and methods are disclosed. These compositions and methods can impart excellent adhesion properties between film layers and the transparent support. These films are useful for medical imaging.
Abstract:
Addition of a surfactant to either the under-layer, the image-receiving layer, or to both the under-layer and the image-receiving layer provides a quick-drying, transparent ink-jet recording film capable of achieving an optical density of at least 2.8 while still having a low haze and producing a number of grey levels.
Abstract:
Transparent ink-jet recording films, compositions, and methods are disclosed. These films can exhibit high maximum optical densities, rapid ink drying, low curl, excellent adhesion between the coating layers and the substrate, and negligible ink transfer between stacked ink-jet recording films after imaging. Such films are useful in medical imaging applications.
Abstract:
Transparent ink-jet recording films, compositions, and methods are disclosed. These compositions and methods can impart excellent adhesion properties between film layers and the transparent support. The films have improved appearance compared to similar high optical density films. Such improved appearance films are produced without requiring reduced drying process throughput. These films are useful for medical imaging.
Abstract:
The compositions and methods of the present application can provide transparent ink-jet recording films that may be used by printers relying on optical detection of fed media. Such films can be useful for medical image reproduction.
