PURPOSE:To obtain an electrifying record display material capable of easily recording with a small-sized device without the use of solvent and free of problems of safety and hygiene and hazard of fire by providing a specific semiconductive resin layer, a metal-containing resin layer, a metal thin layer, and a protective layer. CONSTITUTION:For example, on the surface of a metal-containing resin layer (A) consisting of 5-60vol% metal powder of Al, etc., and a resin matrix and having a surface resistance of 10<5>-10<14> ohm and a thickness of 5-50 microns, formed a solution flow method, etc., a semiconductive resin layer (B) consisting of a conductive material of carbon black, etc., and a resin matrix and having a surface resistance of 1-10<5> ohm and a thickness of 2-30 microns is formed by a solution flow method, etc. Then, on the layer (B), a metal thin layer (C) having a smaller surface resistance (less than 10<2> ohm) than that of the layer (B) and a thickness of 40-5,000A is formed. Furthermore, on the layer (C), a transparent 20 microns or more-thick protective layer (D) free of discharge breakage even when electrified from the layer (A) side is laminated. |
