摘要:
Mixtures of an alkyl vinyl ether/maleic anhydride copolymer or an alkylethylene/maleic anhydride copolymer with cellulose acetate provide protective overcoats for thermally developable materials. These protective overcoats exhibit good adhesion to the emulsion layer, are physically hard, and have good optical clarity while maintaining the sensitometric properties of the materials.
摘要:
When laser beams with a wavelength of 9.3 μm or 9.6 μm are used, a pulse width t (μsec) which is a radiation time of the laser beam and an energy density E (kw/cm2) of the laser beam on an X-ray film are set such that they meet requirements based on an area A between line segments A1 and A2. Moreover, when laser beams with a wavelength of a 10-micrometer band, such as 10.6 μm, is used, the pulse width and the energy density are set such that they meet requirements based on an area B between line segments B1 and B2. As a result, since the pulse width t is within a range of equal to or larger than 3 μsec and smaller than 30 μsec, a high-quality marking pattern with excellent visibility can be formed while improving the productivity of the X-ray film.

Black-and-white, dry processable thermally developable materials have increased stability after imaging with the incorporation of at least 0.0001 mol/m2 of a thermal solvent having one or more >N—C(═O)— groups. Such thermally developable materials include both thermographic and photothermographic materials.

摘要:
A direct thermographic material has one or more thermographic layers on a polymeric support. Two protective layers are disposed over the one or more thermographic layers and both protective layers comprise the same polymer as the predominant binder. The outermost protective layer contains one or more lubricants while the innermost protective layer is substantially free of lubricants.

摘要:
Thermally developable imaging materials have an outermost protective layer that is composed of one or more hydrophilic film-forming components. The predominant film-forming component is a negatively-charged latex polymer that has negatively-charged ionic groups other than carboxy groups. The latex polymer is present as latex particles that have been prepared in the presence of a nonionic stabilizer in an amount of at least 0.5% (by weight) that has an HLB value of 7 to 20. The nonionic stabilizer becomes associated with the latex polymer particles. Both thermographic and photothermographic materials can be prepared with such protective layers.
摘要:
Buried backside conductive layers with increased conductive efficiency can be provided for thermally developable materials using a specific organic solvent mixture to coat a protective overcoat directly disposed over the conductive layer. This organic solvent mixture comprises an alcohol in which one or more film-forming polymers used in the formulation are soluble at room temperature. The alcohol is used in an amount of more than 10 and up to 90 weight % of the organic solvent mixture.
摘要:
Non-photosensitive direct thermographic materials comprise a reducing agent that is a specific ortho-amino-phenol, para-amino-phenol, or hydroquinone compound. These compounds can reduce silver(I) ion to metallic silver to produce a dense black silver image under the short time and high temperature conditions that occur when using thermal print-heads during direct thermal printing. The materials are characterized by their calculated aqueous deprotonation and their calculated anion HOMO energies.
