Abstract
In an electrothermic non-impact image transfer recording material for use in an electrothermic non-impact recording method in which the electrothermic non-impact image transfer recording material is superimposed on a recording sheet, a recording electrode with multiple recording styli and a return electrode are placed in contact with the recording material, and image-delineating signal voltage is applied across the recording material through the recording electrode and the return electrode, so that an ink is transferred imagewise from the recording material to the recording sheet, the improvement wherein the electrothermic non-impact image transfer recording material comprises a base layer and an ink layer, with an intermediate layer interposed between the two layers when necessary, and the base layer comprises as the main components a polyamide resin binder, such as an aromatic polyamide or nylon, and carbon black.
