Abstract

The invention relates to an anti-counterfeiting fiber and anti-counterfeiting paper containing the same. A single anti-counterfeiting fiber comprises a surface A and a surface B, and the visual characteristics of the surface A are obviously different from the visual characteristics of the surface B. The visual characteristics of the surface A and the surface B are respectively presented on the front side and the back side of the paper. When the anti-counterfeiting fiber is added into the paper, a vertical plane or approximate vertical plane of the anti-counterfeiting fiber and the paper is a tangent plane. Thus, more anti-counterfeiting visual characteristics can be created, easy recognizability and difficult imitatability are improved, and the variety of the anti-counterfeiting fiber is enriched.

Description

A kind of anti-false fiber and the cheque paper that contains this anti-false fiber

Technical field

The cheque paper that the present invention relates to a kind of anti-false fiber and contain this anti-false fiber, the different visual signature faces of single anti-false fiber are presented on respectively the positive and negative surface of paper, the particularly vertical plane of anti-false fiber described in paper and paper or near normal face is tangent plane.

Background technology

The manufacture of present nearly all anti-false fiber is all the methods that adopt spinning.About a lot of as manufacturing basic anti-false fiber patent taking spinning technique.But these spinning process have limited the kind of anti-false fiber, the imitated property of the difficulty of anti-false fiber and property easy to identify have also been subject to a lot of restrictions simultaneously.Moreover due to popularizing of spinning technique, the imitated property of the difficulty of this papermaking anti-fake material based on spinning technique progressively reduces.

Summary of the invention

The object of the invention is to propose a kind of special design of anti-false fiber, and the cheque paper that contains this anti-false fiber.There are surfaces A and surperficial B in single described anti-false fiber surface, the visual signature of surfaces A and the visual signature of surperficial B have obvious vision difference, the visual signature of surfaces A and the visual signature of surperficial B are presented on respectively recto and reverse side, when described anti-false fiber is copied after paper, the vertical plane of described anti-false fiber and paper or near normal face are tangent plane; The object of design not only can be created more false proof visual signature like this, and also creates the combination of described anti-counterfeiting characteristic and microtomy, has more enriched the kind of anti-false fiber product.

The object of the present invention is achieved like this:

A kind of anti-false fiber, described anti-false fiber has at least material layer 1 and material layer 2 to form, the surperficial B of the surfaces A of material layer 1 and material layer 2 has obvious visual signature difference, the facade 3 vertical with surfaces A or surperficial B is tangent plane, copy after thin paper, the visual signature of surfaces A and the visual signature of surperficial B are presented on respectively the obverse and reverse of thin paper.

Further, between described material layer 1 and material layer 2, also has layer of spacer material 4.

Further, the layer of spacer material of described layer of spacer material 4 for blocking visible ray, to avoid colored materials layer 1 and colored materials layer 2 optical crosstalk; Or the layer of spacer material of described layer of spacer material 4 for blocking exciting light, to avoid fluorescent material layer 1 or the fluorescent material layer 2 light colour mixture while penetrating that is excited.

Further, on described surfaces A and surperficial B, be also coated with hot melt adhesive layer 5; The object of coated heat melten gel is in order to allow anti-false fiber have the ability of better adhere papers.

Or, in described material layer 1 and material layer 2, containing hot melt adhesive, the object that contains hot melt adhesive is that structure is also simpler simultaneously in order to allow anti-false fiber have the ability of better adhere papers.

The visual signature of described surfaces A and the visual signature of surperficial B are the direct observable visual signatures of naked eyes; Or the visual signature of described surfaces A and the visual signature of surperficial B are the visual signatures that perusal obtains under exciting light irradiates.

Described anti-false fiber has one section of colourless segment of fiber 6 at least on the length direction along fiber; Described colourless section of part can produce in paper meets the transparent effect that light is observed, and makes it more be difficult to be printed imitation.

In the material layer 1 or material layer 2 of described anti-false fiber, at least one material layer is made up of at least two look sections, the iridescent section that described two look sections are different colors, or coloured look section of different color.Described at least two look sections can be two colo(u)r streaks arranged side by side, or end to end two colo(u)r streaks, or two color dots.

Described anti-false fiber is wavy, described wavy two flex points that have at least.

Described anti-false fiber slabbing, can be circular, or square, or polygon etc.

A kind of cheque paper, described cheque paper contains above-mentioned anti-false fiber.

The antifalse effect of an anti-counterfeiting technology is mainly reflected in easy to identify and difficult imitated two aspects.Prior art relatively, the present invention has not only increased the kind of anti-fake product, and has improved property easy to identify and difficult imitated property.

Detailed description of the invention

Embodiment mono-:

Fig. 1 has represented a kind of Fluorescent falsification-preventing fiber sectional view along its length, described cross section contains 5 material layers, is respectively from top to bottom fluorescent blue material layer 2, hot melt adhesive material layer 5 that fluorescein material layer 1, PET thin-film material layer (containing the material that absorbs 365nm ultraviolet light in material layer) 4,365nm that hot melt adhesive material layer 5,365nm excite excite; Vertical or be cutter tangent plane approximately perpendicular to the facade 3 of these material layers.

In the present embodiment, also PET thin-film material layer 4 can be replaced to and a kind ofly on the PET film of saturating ultraviolet light, be coated with one deck and block the material layer of ultraviolet light coating.
