Abstract:

PROBLEM TO BE SOLVED: To provide a laminate for use in the discrimination of genuineness applied to a precious printed matter needing prevention of forgery and alteration such as a bank note, a pass, a passport, a card or the like.

The layers are successively laminated by adhesive layers (4) so that the individual perforating positions of the hole group forming the latent image of the third layer (1c) are arranged corresponding to the individual perforating positions of the perforation group forming the image of the first layer (1a) to obtain the laminate.
