Abstract
Disclosed is a forgery-preventing film having a structure in which a thermoplastic resin film is attached to both faces of a light-shielding layer processed for forgery prevention. It is impossible to recognize the letter information to be protected in the forgery-preventing film without peeling the information-concealing layer therefrom.
