Embodiment Construction

[0036] The specific characteristic performance of the present invention is further described by the following examples and accompanying drawings.

[0037] See figure 1 , figure 2 as shown,

[0038] The composite anti-counterfeiting safety thread 5 of the present invention comprises film layers 1, 2, and amorphous alloy wire 3, and film layer 1, 2 comprises two layers at least, namely upper and lower two layers, and amorphous alloy wire 3 is positioned at film layer 1, 2 between.

[0039] The amorphous alloy wire 3 is amorphous and has electromagnetic properties.

[0040] Amorphous anti-counterfeiting silk coated or dyed by some anti-counterfeiting material is glued between two layers of film. The film layers 1 and 2 may both be polymer film layers, or a polymer film layer and a laser holographic film layer may be used, and patterns are printed on the film layers.

[0041] The film layer is coated or printed with magnetic and optical specific powder anti-counterfeiting ma...

Abstract

The invention discloses a composite antifalsification safety line with manufature method and application method on antifalsification paper. Wherein, the manufacture method comprises: coating thermalsol on single surface bonded by thin film and amorphous alloy wire, locating the amorphous alloy wire between thin film laye, taking thermal treatment; coating thermalsol on double surfaces on outside of thin film, drying, and forming antifalsification film; cutting the said film into antifalsification safety line with required width. This invention presents firstly and makes good use of special electromagnetic property of amorphous alloy wire, realizes in deed the three-line antifalsification for back note paper fit to look over by eyes, identify by machine and analysis by specialist.

Description

technical field [0001] The invention relates to paper used for making banknotes, securities and other articles, more specifically, to a composite anti-counterfeit security thread, its manufacturing method and the anti-counterfeit paper with the security thread. Background technique [0002] Amorphous alloys have only gradually developed since scientists invented the rapid quenching process. Due to their unique structure, efficient preparation process, and excellent material properties, amorphous alloys have become a special focus of material scientists. theme. In the past forty years, with the continuous progress in the basic research, preparation process and application product development of amorphous materials, various amorphous materials have gradually moved towards practical application. From the perspective of magnetic properties, amorphous fibers can be divided into three categories, namely Fe (iron)-based, Co (cobalt)-based and Fe-Co (iron-cobalt)-based amorphous al...
