Abstract
The invention provides anti-counterfeit paper which can be used as anti-counterfeit files such as banknotes, securities, and the like. The anti-counterfeit paper has a transparent window feature at partial area, and a hollow-out pattern formed by the paper can be formed in the window. Therefore, the anti-counterfeit effect is excellent. The window of the anti-counterfeit paper is made of polymer materials, and can be applied to the paper surface by way of polymer film pasting, coating or printing. The polymer film may contains anti-counterfeit materials or other anti-counterfeit feature.
Description
Technical field
The present invention relates to a kind of production method of composite anti-fake paper.This anti-forge paper contains form feature, can in form, form and have the figure line being made up of paper, has excellent antifalse effect.Combination film anti-counterfeiting technology can produce unique antifalse effect.
Background technology
First form anti-counterfeiting technology obtains application on plastic note base material.Because it has unique look and outstanding anti-counterfeiting effect, arouse widespread concern.Paper substrate has also been introduced form feature by multiple complex method.
The method that forms at present form on paper is all generally by first form perforate on paper, by super wide safety line, as WO03085193, pad pasting, as DE4334848, lamination overlay film, as WO2004028825, or paper is compound, as the mode of WO2006066431 forms form on paper substrate.These methods that are compounded to form form generally have obvious sandwich construction, perforate technology is generally to form by the form of cross cutting, there is sharp edge, the paper sheet thickness of form part and the other parts of paper have obvious difference, and the introducing of plastic material all may cause difficulty to the printing performance of paper, the size and shape of form part can be subject to certain restrictions.There is defect in such paper form, imitator can form perforate equally and form form at overlay film on paper.
Separately have the through hole in a kind of paper form to form in paper-making process, as CN101220570, the edge of this through hole has scrambling, and irregular fiber is outstanding from paper edge.This method makes imitator after paper forms, not forge through hole.But the bore edges thickness forming like this has transitional region, but the shape in hole and position are difficult to control accurately, and not attractive in appearance.
Can realize the change of the paper transparency by changing the optical property of paper, as adopted the method for paper clarifier, with flood, be coated with or in the mode of adding be applied to paper surface, as Lu Wei, paper clarifier, papermaking chemical product, 1997,9(3).Cellophane paper prepared by this method, general speed of production is slow, is not suitable for the production of continuous industry, and the properties of transparency of paper may produce notable difference due to the difference of paper structure.In recent years, by the mode of printing, the serialization application mode of the paper clarifier that can realize after clarifier ultra-violet curing, as US6103355, this method is more difficult for thicker paper application and ultra-violet curing, the top sizing of paper can produce larger impact to this method in addition, and the properties of transparency of paper is not good.The use of clarifier is difficult to form the paper of the high grade of transparency, and the filler of paper, as titanium dioxide, may cause larger impact to the application performance of clarifier.
Summary of the invention
The invention provides a kind of anti-forge paper, can be used for making the security document such as banknote, security.
First on paper, react the mode of curing or polymer solution solvent evaporates at the Security element of paper surface using polymer film by pad pasting, polymer hot melting coating, prepolymer, then the part paper of removing film region by the method for mechanical grinding or laser-induced thermal etching, finally can form the anti-forge paper that contains polymer form.Removing paper and mold process can carry out simultaneously, if the gap of setting die roller 1 and polishing roller 2 is to remove the paper of mould corresponding part, to form the polymer form with hollow out effect, as shown in Figure 6.
The production method of the form anti-forge paper of existing bibliographical information is all first on paper, to form perforate, then applied film forms form, the form that this method forms cannot form the form with hollow out paper effect, cannot in form, retain paper and form the figure line being made up of paper.In this programme, can form the form of various complicated engraved structures in conjunction with the relief printing plate design on die roller 1, as contained the paper part not being connected with paper outside form in form, the example that has provided a complicated form of accompanying drawing 7 and 8 signals and the profile of form part.The form of this kind of structure is to make by existing method, first on paper, forms the method for film forming after perforate and obtains.
The form that method for adhering film forms can adopt the film of anti-counterfeiting characteristic, as holography, light change etc.
The polymer form of coating film forming can contain antiforge function material, comprises infra-red material, magnetic material, luminescent material.
Anti-fake material can be infra-red material (as CN200710062742.7 has infra-red material used in the anti-forgery ink of obvious contrast to different-waveband infrared absorption/reflection), magnetic material (as the iron oxides magnetic paint of BASF AG) and/or luminescent material (as luminescent material used in CN02148815.0 Light-emitting Anti-counterfeiting Ink And Preparation Method And Use).In one embodiment of the invention, the combination that anti-fake material is these materials.In preferred embodiments, anti-fake material is except comprising infra-red material, magnetic material and luminescent material, the transparent/translucent pigment that can also be or comprise orientating function material (as disclosed in WO2010149266).
It should be apparent to those skilled in the art that, in the situation of the coating material that comprises the anti-fake material with orientating function material in use, after applying, through ink pigment orientation, solidify after, under reverberation, can produce directional effect pattern, and under transmitted light, for forming directed image by invisible by transparent pigment.The method of this hidden image has more excellent antifalse effect.
But, it should be apparent to those skilled in the art that, anti-fake material is except infra-red material, magnetic material, luminescent material and orientating function material, can further include marker material, coated interference pigment, metal effect pigments, optic metachromatic material, sensitive material, intellectual material, thereby the form obtaining can independently choose a kind of anti-fake material feature, it can be also the combination of multiple anti-counterfeiting characteristic.
