(54) Electrosensitive transfer film


(57) An electric discharge transfer film material comprising at least two layers, the first of which is (a) an electrically anisotropic support layer (2) having electroconductive particles dispersed in a resin matrix. The electroconductive particles can be graphite particles having a particle size between 0.1 to 20 microns, carbon black particles having a particle size between 25 to 500 millimicrons, or metal powders, and (b) at least one thermal or electrothermal transfer layer (4) in the form of a resin layer capable of being broken by electrical discharge and transferred to a record sheet, e.g., paper.
