FORGERY-PROTECTING PAPER AND FORGERY-PROTECTED PRINTED MATTER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a forgery-protecting paper that overcomes the problem that the printing quality is deteriorated by disturbance of electric field, when conventional forgery-protecting paper is printed through the electrophotography and provide forgery-protected printed matters using the same.

SOLUTION: Nonconductive threads 4 are inserted between laminated paper layers 2 or on the pore-opened part 3 that does not have the uppermost paper layer, then they are laminated whereby the problem is solved. A hologram layer 6, a nonconductive reflection layer 7 and a nonconductive pattern layer 8 are laminated in order on a nonconductive plastic film 5 and the laminate is used as a thread 4.
