Abstract:
PROBLEM TO BE SOLVED: To provide a forgery preventive sticker against which counterfeit can not easily be made by printing. SOLUTION: Provided is the forgery preventive sticker which has a transparent film 40, a metal vapor-deposited layer 30 provided on the reverse surface of the transparent film 40, and a peeling-treated peelable sheet 10 stuck on the metal vapor-deposition surface of the metal vapor-deposited layer 30 across a sticky layer 20, the sticker being characterized in that a print part which is printed with transparent print ink 50 and a non-print part S which is not printed with the transparent print ink 50 are formed on the top surface of the transparent film 40 and the transparent film 40 present at the non-print part S and sticky layer 20 are dissolved with chemicals 70.

Abstract:
PROBLEM TO BE SOLVED: To provide a transfer sheet for forgery preventing indication which exerts a high security effect and improves durability and which makes it possible to give the forgery preventing indication to various objects at a low cost and reliably. SOLUTION: A transparent film is laid on a base sheet 2 for peeling off, with an easy-to-peel layer 3 interlaid. The transparent film is an angle-dependent film 4 of which the visual effect varies according to an angle of sight. An angle-dependent layer 7 formed of angle-dependence ink which makes the color of reflected light vary according to the angle of sight and a fluorescent printed layer 6 formed of fluorescent ink which emits the fluorescent light in a visible range in reaction to a light beam of a prescribed wavelength are provided for the angle-dependent film 4, and a transfer adhesive layer 8 is formed on the side of the angle-dependent film 4 whereon the angle-dependent layer 7 and the fluorescent printed layer 6 are formed.
