    摘要: An improved apparatus and process are described in which a direct negative is formed using commercially available multi-stylus recording heads. A negative precursor comprised of a transparent support and an opaque thermoplastic ink layer carried thereon, is brought into contact with an ink receiving medium comprised of a resistive layer and a thin conductive ink receiving layer thereon. Electrical currents are provided by the recording styli of the multi-stylus recording head to the resistive layer to provide sufficient heat to soften regions of the opaque ink brought into contact with the conductive layer, by which regions of said opaque ink are transferred to the ink receiving conductive layer. In this manner, a pattern of opaque ink regions is removed from the surface of said transparent support, whereby a direct negative is formed having light opaque and light transparent regions.

    摘要: Electroerosion recording materials for "direct negative" and "offset master" are provided with a surface protective coating of solid conductive lubricant dispersed in a hydrophilic, crosslinked polymeric matrix. The protective films are especially useful where direct offset masters are produced without removal of non-eroded lubricant film.The recording medium of this invention provides use as a defect-free "direct negative" and/or "direct offset master", without requiring the removal of the overlayer prior to use on the printing press. The protective coatings are applied from aqueous dispersions of polymer-particulate compositions and thus avoiding the use of organic solvents.

    摘要: An improved resistive ribbon for resistive thermal transfer printing is described in which the resistive layer of the ribbon has enhanced thermal and mechanical properties. The ribbon is a multi-layer ribbon including a resistive layer, an electrical current return layer, and an ink layer. The resistive layer has an additive therein which phase separates and concentrates in a thin surface region near the interface of the resistive layer and the current return layer. This thin region has superior thermal and mechanical properties, and protects the remainder of the resistive layer during the printing operation, without adversely affecting the mechanical, electrical, and thermal properties of the overall resistive layer. These additives are those which will form a polymer having a sufficiently high dissociation temperature to withstand the adverse effects of heat build-up at the interface. Suitable additives include graphite fluorides, fluorocarbon resins such as Teflon.RTM., and CeF.sub.4.

    摘要: Electroerosion recording materials are provided with a surface lubricant film of particulate lubricating nonconductive graphite fluoride and optional conductive materials in a polymeric binder. The lubricating agents reduce stylus scratching of the conductive layer during electroerosion printing, improve contrast, provide a beneficial coating on the writing electrode or stylus and improve the handling and writing characteristics of the recording material. The lubricating agents/polymer films are especially useful (1) where the substrate of the recording material is light transmissive and, after the electroerosion process, the resulting product is suitable for direct-negative applications and (2) where direct offset masters are produced by removal of noneroded lubricant film.

    摘要: Electroerosion recording materials of superior scratch resistance are provided without the need for a lubricant overcoat by incorporating a hard, lubricating hydrophobic polymer layer between the support and the removable, thin conductive layer to reduce plastic deformation of the support under stylus writing pressure. The intermediate polymer layer provides a highly adhering surface for the overlying aluminum film and contains graphite fluoride and/or fluorocarbon resins such as Teflon.RTM. and hard particles such as silica. The materials may be used in various printing processes including making directly readable images, direct negatives and wear resistant offset printing masters.

    摘要: This invention describes a direct master for offset printing. The master comprises a thin metal layer, a thermoplastic layer disposed on the metal layer, and a conductive oxide layer evaporated on the metal layer. When this master is subjected to electrical pulses from the styli of a printer, some of the thermoplastic layer diffuses through the oxide layer changing selected regions of the oxide layer to oleophilic regions.
