<p><P>PROBLEM TO BE SOLVED: To provide an overprint card in which whiteness and brightness are both improved without increasing a layer thickness of a white layer, by having an overprint layer such as a concealing layer and a white layer for the purpose of preventing viewing of an internally existing magnetic layer, an IC chip or the like from the outside. <P>SOLUTION: In the overprint card, a concealing layer, a white layer and a surface protecting layer are at least laminated in this relative order on a card substrate. The overprint card is characterized in that the white layer contains a white pigment and a minute filler for improving whiteness and that, on the surface of the surface protecting layer, there is provided minute ruggedness for accelerating scattering of light. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
