Definitions

  • the present invention relates to a composite electrosensitive transfer material, and more particularly, to a reusable electrosensitive transfer film.
  • the electric discharge recording system is a process which comprises applying an electrical signal of several hundred volts and several watts in the form of an electric voltage, and breaking a semiconductive recording layer on the surface of a recording layer by electric discharge, thereby to form an image on the recording layer or on a substrate superimposed on the recording layer.
  • This process is a "direct imaging" process which does not require processing operations such as development and fixation, and is in widespread use as a simple recording process.
  • the process finds applications in facsimile systems, various measuring instruments, recording meters, record displays in computers, and processing of electrostencil master sheets.
  • a discharge recording stylus In the electric discharge recording, a discharge recording stylus is directly contacted with the recording surface of an electric discharge recording material. Discharging is performed through the stylus to break the recording layer, and to form an image on the recording surface.
  • N akano et al in U.S. Patent 4,163,075 and relates to the use of an electrosensitive transfer film.
  • a receiving medium such as paper
  • an electric discharge stylus is moved in a regular pattern across the back of the transfer film. Provision is generally made to ground either one edge or the front surface of the transfer film.
  • a voltage on the order of 150 to 200 volts is applied to the stylus, current flows through the sheet and matter is caused to be transferred to the receiving sheet, e.g., paper.
  • the film disclosed by Nakano et al in U.S. Patent 4,163,075 comprises three layers, namely a film support layer and two transfer layers.
  • the support layer is composed of a metal powder-containing resin layer, e.g., electrolytic copper powder having an average diameter of 2 microns dispersed in a vinyl chloride resin.
  • an electric discharge recording material which comprises (a) an electrically anisotropic support layer having electroconductive particles dispersed in a resin matrix wherein said electroconductive particles are: (1) graphite particles having a particle size between 0.1 to 20 microns, (2) carbon black particles having a particle size between 25 to 500 millimicrons, or (3) metal powders; and (b) at least one thermal or electrothermal transfer layer in the form of a resin layer capable of being broken by electrical discharge and transferred to a record sheet.
  • a preferred resin matrix comprises a phenoxy resin of the formula: where n is about 100.
  • One embodiment of the present invention is an electric discharge recording material which comprises: (a) a semiconductive resin layer capable of being broken by electric discharging which has a surface resistance of 105 to 1016 ohms and a volume resistance of 10 3 to 1 0 14 ohms-cm; (b) an electroconductive electrically anisotropic resin layer containing electro- conductive particles such as graphite, carbon black or metal powders as described above, which is laminated on one surface of the semiconductive resin layer (a); and a conductive layer having a surface resistance of not more than 10 4 ohms and a volume resistance of not more than 10 2 ohms-cm, which is laminated on the other surface of the semiconductive resin layer (a).
  • Another embodiment of the present invention is an electric discharge recording material which comprises at least one resin layer capable of being thermally or electrothermally transferable to another substrate, and an electrically anisotropic carbon black or graphite-containing resin layer which is laminated on one surface of one resin layer.
  • Still another embodiment of the present invention is an electric discharge recording material, e.g., film, which comprises at least one resin layer capable of being thermally or electrothermally transferred to another substrate and an electrically anisotropic carbon black or graphite-containing support layer.
  • the graphite and carbon black particles exhibit particle sizes previously defined herein.
  • the support layer is laminated onto one surface of the resin layer.
  • the film structure as illustrated in FIGURE 1, comprises an electrically anisotropic (unidirectionally conductive) electroconductive particle-support layer 2 and two transfer layers, namely layers 4 and 6.
  • a graphite-containing resin When a graphite-containing resin is employed as layer 2, it generally contains between 5 to 65% and preferably between 15 to 45% by weight graphite based on the weight of the resin. Best results are obtained when the layer contains between 25 and 35% by weight graphite, based on the weight of the resin.
  • the particle diameter of the graphite used in this layer is also critical to the successful practice of the subject invention. Generally, the particle size is generally between 0.1 to 20 microns, and preferably between 0.1-5 microns, with best results being achieved with particles between 0.1 and 1 microns.
  • graphite particles useful in the anisotropic support layer can be prepared by grinding the graphite particles in the presence of water or other solvent having substantially the same freezing and vapor pressure properties as water, e.g., tertiary butyl alcohol, cyclohexane, benzene, dioxane, and para-xylene.
  • water or other solvent having substantially the same freezing and vapor pressure properties as water, e.g., tertiary butyl alcohol, cyclohexane, benzene, dioxane, and para-xylene.
  • water or solvent as defined herein, the balance being solids, namely the graphite particles. It is understood that the amount of water or solvent employed is not critical and can vary over wide ranges both below 70% and above 80% because the solvent or water is eventually driven off in accordance with this process.
  • a binding polymer is added to the graphite slurry, either during the grinding step or immediately after the grinding step for the purpose of forming a film or coating on the individual particles of graphite.
  • the polymer employed is to be soluble in the water or solvent of the slurry.
  • Suitable polymers include, e.g., polyvinyl alcohol, gelatin or methyl cellulose.
  • Freezing of the slurry is achieved by lowering the temperature to a point wherein the physical state of the solvent changes from liquid to solid.
  • the frozen slurry is then dried, under conditions such that the water solvent present is caused to sublime, i.e., the solid is directly converted to the vapor form, without passage through the liquid state.
  • the process results in the formation of a substantial amount of undamaged polymeric coated graphite particles having a diameter of at least 0.2 microns. By substantial amount, it is intended that at least 90% of the particles have a diameter of at least 0.2 microns.
  • Sublimation of water, or other solvents used in place of water, which exists in the solid state can be caused to change to a gaseous phase without an intermediate phase, under well-known changes in pressure alone, temperature alone, or a change in both temperature and pressure. Generally, sublimation can be produced under the influence of a high-pressure vacuum.
  • graphite particles be dispersed in the resin in such a manner the graphite is not reduced in size to dust particles (under 0.1 micron).
  • Graphite particles are therefore dispersed in a resin, generally in a molten state, by means of a high sheer blender, e.g., a Waring blender, Cowl or Greer blenders, rather than by impact grinding methods, e.g., ball milling or dispersing in an attritor.
  • impact grinding methods e.g., ball milling or dispersing in an attritor.
  • the latter methods cause the graphite particles to break up into particles less than 0.1 micron size, adversely affecting the electrically anisotropic properties of the layer.
  • the electrically conductive carbon-black-containing resin of layer 2 contains generally between 60 to 70% by weight carbon black. Best results are obtained when the layer contains 65% by weight carbon black, based on the weight of the resin and carbon black.
