PURPOSE:To obtain a sheet having transparent parts in simple steps, by granulating finely the one surface of a transparent synthetic resin sheet, and rendering partly the granulated surface smooth. CONSTITUTION:The one surface of the transparent synthetic resin sheet for example of PE, PP, PS, ABS resin, PVC, polymethyl methacrylate, etc. is finely granulated. Then the fine recesses are filled partly with a transparent ink for example by printing, coating, or melting by heating to make the particular parts smooth to obtain the aimed sheet. |
