PURPOSE:To enable a desired image to be displayed as a positive image with a metallic luster on the back side of a recording layer and with a high quality feeling, by protecting the recording layer on a transparent base with a transparent film, and printing a negative image of a predetermined pattern on the surface of the transparent film. CONSTITUTION:A negative image N of a predetermined pattern is printed on the surface of a protective film 23, consisting of a transparent synthetic resin film, of an optical card 20. Namely, an ink 24 forms, for example, a gray ground (opaque layer) over substantially the entire surface of the protective film 23, leaving uninked parts 24c, 24f in the area of the pattern so that the protective film 23 is exposed in the pattern area surrounded by the gray ground. The negative image pattern N is protected by a hard coat 25 of, for example, a UV-curable resin. The protective film 23 is adhered to a recording layer 12 on a base 11 by a transparent adhesive layer 16. As a result, the surface of the recording layer 12b is partly seen through the transparent adhesive layer 16, protective layer 23 and hard coat 25, in the pattern surrounded by the gray ground of the printing ink 24, and shows a high reflectance. Therefore, the pattern is displayed as a positive image with a metallic luster.
