PURPOSE:To obtain a negative image, make a projected image easy to see and facilitate coloration, by a method wherein a specified metal-containing resin sheet is laminated on a specified thin metallic layer provided on one side of a transparent thermoplastic resin sheet, an electric discharge recording stylus is brought into contact with the metal-containing resin sheet, and an electiric current is passed thereto to break only the thin metallic layer by electric discharge. CONSTITUTION:The thin metallic layer is provided on one side of the transparent thermoplastic resin sheet to obtain a recording sheet. The thickness of the metallic layer is 20-100Angstrom , and the surface resistance thereof is not higher than 10<2>OMEGA. The metal-containing resin sheet consists of a resin matrix and 5- 60vol% of a metallic powder, and the surface resistance is set to be 10<5>-10<16>OMEGA. The metal-containing resin sheet is laminated on the thin metallic layer, a discharge recording stylus is brought into contact with the sheet, and an electric current is passed thereto to break only the thin metallic layer by electric discharge. Since the image-projecting sheet is produced in this manner, a negative image can be easily obtained, coloration can be easily accomplished, and a projected image is made easy to watch. |
