Abstract

The utility model relates to an anti-counterfeiting fiber and anti-counterfeiting paper containing the anti-counterfeiting fibers. According to the anti-counterfeiting fiber, a surface A and a surface B are arranged on the surface of the single anti-counterfeiting fiber; an obvious vision difference exists between a visual characteristic of the surface A and a visual characteristic of the surface B. The visual characteristic of the surface A and the visual characteristic of the surface B are represented on the front face and the back face of the paper respectively. After the anti-counterfeiting fibers are doped into the paper, vertical planes or approximate vertical planes of the anti-counterfeiting fibers and the paper are tangent planes. With the adoption of the design, more anti-counterfeiting visual characteristics can be created, so that the easy identification and the difficult copying are improved and product categories of the anti-counterfeiting fibers are 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 utility model relates to a kind of anti-false fiber and contains 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 the near normal face is tangent plane.

Background technology

The manufacture of present nearly all anti-false fiber is all the methods that adopt spinning.It is relevant that to take spinning technique a lot of as manufacturing basic anti-false fiber patent.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 also have 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.

The utility model content

The purpose of this utility model is the special design that proposes a kind 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, after described anti-false fiber is copied paper, the vertical plane of described anti-false fiber and paper or near normal face are tangent plane; The purpose 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 purpose of this utility model is achieved like this:

A kind of anti-false fiber, described anti-false fiber at least is comprised of the first material layer 1 and the second material layer 2, the surperficial B of the surfaces A of the first material layer 1 and the second material layer 2 has obvious visual signature difference, the facade 3 vertical with surfaces A or surperficial B is tangent plane, after copying 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, also has layer of spacer material 4 between described the first material layer 1 and the second material layer 2.

Further, the layer of spacer material of described layer of spacer material 4 for blocking visible ray, to avoid coloured the first material layer 1 and coloured the second material layer 2 optical crosstalks; Or the layer of spacer material of described layer of spacer material 4 for blocking exciting light, to avoid fluorescence the first material layer 1 or fluorescence the second material layer 2 light colour mixture while penetrating that is excited.

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

Perhaps, in described the first material layer 1 and the second material layer 2, contain hot melt adhesive, the purpose that contains hot melt adhesive is that structure is also simpler simultaneously in order to allow anti-false fiber that the ability of better adhere papers is arranged.

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 the visual signature of described surfaces A and surperficial B is the visual signature that perusal obtains under exciting light irradiates.

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

In first material layer 1 or the second material layer 2 of described anti-false fiber, at least one material layer is comprised 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.

In the form of sheets, the surface of its first material layer 1 and the second material layer 2 is circular to described anti-false fiber, 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.Relative prior art, the technical solution of the utility model has not only increased the kind of anti-fake product, and has improved property easy to identify and difficult imitated property.
