PURPOSE:To provide the titled sheet increased in the amount of recording information and enabled in coloring expression of plural colors, obtained by a method wherein a first color layer, a light color type color layer, a matte second color layer and a matte metal vapor deposition layer are formed on one surface of a carrier substrate while paper is adhered to the other surface thereof. CONSTITUTION:Paper 9 is adhered to one surface of a carrier substrate 1 and, on the other surface thereof, a first color layer 2 with a thickness of 2-6mum, a light color type color layer with a thickness of 2-6mum and a low m.p. such as a white layer, a second color layer 4 with a thickness of 1-3mum of which the surface is made matte, a matte metal vapor deposition layer 5 and a surface protective thin coating layer 6 are laminated. In the resulting recording sheet, signal voltage of 25-35V is applied between an electrode needle and an electrode placed on the coating layer 6 and the coating layer 6 and the vapor deposition layer 5 are subjected to discharge breakdown to expose the color layer 4 through the broken hole 7. In the next step, signal voltage of 25-35V is applied between an electrode needle and an electrode placed on the coating layer 6 and the coating layer 6 and the vapor deposition layer 5 are subjected to discharge breakdown to expose the color layer 4 through the broken hole 7. In the next step, signal voltage of 50-70V is applied thereto and the coating layer 6, the vapor deposition layer 5 and the color layers 4, 3 are subjected to discharge breakdown to visualize the color layer 2 through the broken hole 8. |
