Claims

[Claims for Utility Model Registration] (1) A plurality of through holes are formed in an opaque or translucent center sheet in a manner to expose a predetermined pattern, etc., and at least one side of the center sheet is made of thermoplastic resin. A transparent or translucent intermediate sheet with a lower light transmission density than the center sheet is layered, and outer sheets made of opaque thermoplastic resin are layered on both sides of these polymerized layers to form the entire sheet. A watermarked anti-counterfeit card made by integrated heat-pressure lamination. (2) The watermarked anti-counterfeiting card as set forth in claim 1 of the utility model registration claim, in which the center sheet, intermediate sheet, and outer sheet are all made of vinyl chloride resin.
