摘要:
A discharge recording medium comprising a substrate and a thin metal layer which is formed on the substrate layer and is made of aluminum containing at least one metal selected from the group consisting of manganese, copper and magnesium, which has good environmental resistance and printing characteristics.
摘要:
The present invention provides an improved electroerosin recording medium which comprises, in a preferred embodiment, a non-conductive support, a hard, abrasion resistant layer, preferably comprising an organic polymer matrix containing an inorganic particulate material, a thin conductive film, typically of a metal such as aluminum, and an abrasion resistant overlayer that most preferably comprises a solid conductive lubricant dispersed in an organotitanium regaent modified polymer system. The overlayer is highly adherent to the conductive surface, has a low organic binder content and provides effective protection against abrasion of the conductive layer and fouling of a print head during electroerosion printing.
摘要:
Electroerosion recording materials of superior scratch resistance are provided by incorporating a hard, crosslinked polymer film or 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 may be unfilled or filled with solid particles, such as silica particles. The materials may be used in various printing processes including making directly readable images, direct negatives, and offset masters.
摘要:
Electroerosion recording materials are provided with a surface lubricant film of lubricating conductive material in a polymeric binder. The lubricating conductive agent reduces stylus scratching of the conductive layer during electroerosion printing, improves contrast, provides a beneficial coating on the writing electrode or stylus and improves the handling and writing characteristics of the recording material. The lubricating conductive agent/polymer films are especially useful where the substrate of the recording material is light transmissive and, after the electroerosion process, the resulting product is suitable for direct-negative applications.
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 electrosensitive recording member comprising, in combination, (1) a base support; (2) a conductive polyester layer disposed on the base support; and (3) a contrasting surface recording layer with respect to said polyester layer and combustible at the temperature developed during passage of marking current through said medium to selectively reveal the underlying contrasting polyester layer. The polyester layer is stable and not subject to depolymerization when subjected to the marking temperatures of an electronic recording member, e.g., stylus.
摘要:
Metalized recording papers contain, located on a paper web, a firmly adhering varnish coating in which mineral fillers and/or pigments combined with wax particles are embedded and the external surface of the varnish coating is covered with a metal layer, preferably an aluminum layer obtained by vacuum evaporation.
摘要:
Method and apparatus for fabricating electrosensitive paper with a white finish. The paper comprises a base layer of paper, a solvent-based resin coating, and a thin surface layer of aluminum, optionally including a white overcoat. A mixture of solvents may be employed having different evaporation rates, providing a white appearance of the metallized layer. The solvent mixture may include a relatively volatile true solvent, and a less volatile diluent. After application of the resin coating in solution to the paper base, the solvents may be evaporated using a three-stage drying process in which the first stage involves an elevated temperature with turbulent air flow.

Electrosensitive recording materials (15) made with a substrate (16) of paper or plastic film; an intermediate layer (17) including a film-forming organic binder, small-sized solid particulates and large-sized solid particulates; and a thin even layer of metal (18) vacuum-deposited over the intermediate layer.
摘要:
The invention concerns a process for producing compact, cellulose acetobutyrate based lacquer layers with a high degree of dullness for record carriers coated with a metallic or metalliferous layer, wherein high-molecular polysaccharides, having side chains and containing lignin, are admixed with the basic lacquer compound as a filler with a particle size distribution of less than 10 .mu.m and a molecular weight of about 10.sup.6.
