At least a part of the surface of the material is made to be non-printed part 3a where printing is not applied. On either face except the face constituting the surface of the base material, a printing 5 being visible from at least the non-printed part 3a is applied. On the backside of the lowermost layer center core sheet 2, a printing 6 with an impermeable ink is applied on the whole face. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
