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. 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. Such films do not exhibit excessive ink drying times. These films exhibit high maximum optical densities and have low haze values. These films are useful for medical imaging.
