<P>PROBLEM TO BE SOLVED: To provide an anti-counterfeit paper whose anti-counterfeit layer can identically be seen from the front and back surfaces of the form, even when a sled in which the anti-counterfeit layer (representative examples are micro letters) is formed is made at a position deviated from the front or back surface in the form, and to provide an anti-counterfeit printed article. <P>SOLUTION: The anti-counterfeit paper having a thread provided with an anti-counterfeit layer on the surface, between paper layers, is made to change the opacities of the paper layers so that the anti-counterfeit layer provided the thread can approximately identically be seen, when observed from the front surface and back surface of the form. <P>COPYRIGHT: (C)2009,JPO&INPIT |
