Abstract
A method for performing electric discharge recording on the recording surface of an electric discharge recording material using a discharge recording stylus, which comprises interposing an electrically anisotropic non-recording layer between the recording surface and the discharge recording stylus, said non-recording layer being prepared by dispersing a metal powder in a resin matrix and having a surface resistance of at least 10.sup.8 ohms and a volume resistance of not more than 10.sup.4 ohms-cm, and performing electric discharge recording through the non-recording layer; and a composite discharge recording material which comprises (a) an electric discharge-breakable semiconductive resin layer having a surface resistance of 10.sup.5 to 10.sup.16 ohms and a volume resistance of 10.sup.3 to 10.sup.14 ohms-cm, (b) a metal-containing resin layer having a surface resistance of at least 10.sup.8 ohms and a volume resistance of not more than 10.sup.4 ohms-cm, which is laminated on one surface of the semiconductive resin layer (a) and is prepared by dispersing a metal powder in a resin matrix and (c) a conductive layer laminated on the other surface of the semiconductive resin layer (a) …
