Embodiment 1

[0036] figure 1 A specific embodiment of the security thread of the present invention is given, the security thread includes two anti-counterfeit layer units 2, and a connection line 1 connecting the two anti-counterfeit layer units 2, the anti-counterfeit layer The chip units 2 are distributed in series on the connection line 1 . Here, the anti-counterfeiting layer unit 2 can be selected in any shape, such as circle, square, rhombus or other irregular shapes, and the connection line 1 can also be selected in any shape with connection function, such as line, chain and so on. In this embodiment, the unit of the anti-counterfeiting layer 2 is circular, and the connecting line 1 is linear. In addition, in this embodiment, the anti-counterfeiting layer unit 2 includes a composite structure multilayer film provided with anti-counterfeiting features, the composite structure multilayer film is provided with connection holes for connecting the connection lines, and the composite stru...

Embodiment 2

[0043] In the above embodiment, the length of the anti-counterfeit layer unit can be selected as 2-6mm, preferably 2.5-3.5mm, the interval of the anti-counterfeit layer unit is 5-25mm, and the diameter of the connecting line is 10-200 μm, It is preferably 20-100 μm, and the above-mentioned values ​​are selected according to the needs of use. The anti-counterfeiting layer unit can also be provided with a plurality of anti-counterfeiting features as required, and the connecting line can be made of nylon or polymer fiber, or other white thin strands. Anti-counterfeiting features are also set up online.

[0044] In the present embodiment, the connecting wire 1 is a nylon wire with a diameter of 40 μm, and the anti-counterfeit layer unit 2 is a disc with a diameter of 2.5 mm (hollowed out in the middle), and here there are three anti-counterfeit layer units 2, They are connected in series through the connection line 1, and the distance between the sheets is 15mm. At the same time...

Embodiment 3

[0046] The connecting wire 1 is a nylon wire with a diameter of 800 μm, and the anti-counterfeiting layer unit 2 is a disc with a diameter of 3.5 mm (hollowed out in the middle) connected in series, and the distance between the sheets is 25 mm. At the same time, the composite structure multilayer film of the anti-counterfeiting layer unit 2 includes a luminescent anti-counterfeiting layer formed by a layer of rare earth sulfur oxides Gd2O2S:Tb and La2O2S:Tb, which has a good anti-counterfeiting function.

Abstract

The invention discloses a safety line which comprises at least two anti-counterfeiting layer sheet units and also comprises a connecting wire for connecting the at least two anti-counterfeiting layer sheet units, wherein the anti-counterfeiting layer sheet units are serially connected and distributed on the connecting wire. The safety line solves the technical problems of difficulty in accurate positioning and poorer controllability and repeatability of the safety line in the prior art because the safety line is smaller and disperse during installation of a plurality of safety lines, can be accurately positioned, has better controllability and repeatability, and is especially suitable for safety anti-counterfeiting fields such as paper money, negotiable securities, tickets, certificates and the like.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting materials and anti-counterfeiting technology, in particular to a security thread which can be used for banknotes, valuable securities, ticket cards and similar items. Background technique [0002] At present, it is necessary to set anti-counterfeiting marks in many paper-based or similar items to improve their security performance, such as banknotes, securities, tickets, certificates, etc., by setting security lines to make them easy to identify, but not easy to be counterfeited or faked. In the prior art, anti-counterfeiting elements such as anti-counterfeiting fibers, special-shaped sheets, and flashing sheets are usually used in the paper to achieve it. For example, Chinese patent document CN100342081C discloses a security thread for improving paper security, including the base layer. An optical anti-counterfeiting information layer and a magnetic anti-counterfeiting information layer are res...
