Abstract

An image-recording material comprising a support, at least the surface of which is electrically conductive, having on the electric conductive surface a layer of an electron-sensitive composition substantially containing (a) a trivalent cobalt complex compound, (b) a compound having a conjugated .pi. bond system capable of forming at least a bidentate ligand with a divalent or trivalent cobalt ion, and (c) a film-forming organic high polymer, the electron-sensitive composition further containing (d) a compound capable of absorbing electromagnetic waves of a wavelength not longer than about 350 nm as an ultraviolet light absorbing agent, an image-recording process using the image-recording element and an apparatus for forming visible images using the image-recording material.
