Abstract
The present invention discloses a kind of coating that can discern security carrier that has that is used for printing of bank note, Valued Securities, sign or makes sign, mark, and the using method of this coating and with the authenticity identification method of the goods of this coating making.Coating of the present invention is to add the paramagnetism stable compound that has distinguishing characteristics as its electron spin resonance spectroscopy that can discern security carrier in commonly used or special coating matrix.Using method of the present invention is to print or smear or impress with seal with described coating.Truth identification of the present invention is that goods are inserted in the sample cavity of electron spin resonance spectrometer, measures its spectrogram, and contrasts identification with the original sample collection of illustrative plates.
Description
The present invention relates to a kind of coating that can discern security carrier that has that is used for printing of bank note, Valued Securities, sign or makes sign, mark, and the using method of coating and with the truth identification discrimination method of the goods of this coating made.Coating of the present invention is meant that with all kinds of commonly used or special solvents, resin, pigment be the coating of matrix.
False proof following measures of using of Valued Securities or sign more:
1, fluorescence mark: with regional area fluorescence coating printing security or banknote or sign.Its goods are shone with special light sources, show its secret mark.
2, magnetic mark: on banknote, Valued Securities or sign, print off secret mark with special magnetic coating.Its goods are checked with special magnetic testing instrument.
3, hologram marking: the mark of making hologram pattern with holographic method.As Chinese utility model patent 88200594.4 disclosed methods.
4, liquid crystal mark: the coating with the band liquid crystal material is printed on security or the sign.Its identification is to make liquid crystal colour developing or variable color under light, heat or electric condition.As Chinese utility model patent 90224525.2 disclosed technology.
5, adopt look thermal-reactive coating to make mark: as Chinese invention patent application 90102757.X.
Above-mentioned prior art has the following deficiency:
1, makes difficulty.
2, the made goods of some prior art will have the visible marking on it, as the liquid crystal mark.
3, its antifalse effect relative mistake some.Be difficult to distinguish similar goods during particularly its identification is differentiated or make with class methods in the goods of non-identical making method.
The objective of the invention is to overcome the deficiencies in the prior art, a kind of coating that can discern security carrier and the using method and goods distinguishing method between true and false of coating thereof of having is provided.
Purpose of the present invention realizes with following measure:
With commonly used or special solvent, resin, pigment etc. is matrix, adds the paramagnetism stable compound that has distinguishing characteristics as its electron spin resonance spectroscopy that can discern security carrier therein.This compounds can be a manganous salt, or DPPH, or other stabilized radicals, also can be to be had nothing in common with each other by two kinds or several compositions and electron spin resonance spectroscopy thereof, but the electron spin resonance spectroscopy of its mixture has the mixture of distinguishing characteristics.
, print or smear in all zones as banknote, Valued Securities, denotation token at article printed or that make with aforementioned coating; Perhaps, at article printed or that make, as printing or smear in the part of banknote, Valued Securities, denotation token or the specific region; Perhaps in the sign of making, mark, coating and the interior security carrier discerned thereof are attached on the finished product with the seal mode of adding a cover.
Discriminating with above-mentioned coating and the obtained goods of method will be identified whole or local the placing in the sample cavity of electron spin resonance spectrometer of thing, be recorded its spectral line, be compared with the original sample spectral line, can be distinguished its true and false.
The security carrier discerned of its adding is a manganous sulfate in the embodiment of the invention, or DPPH, or the mixture of manganous sulfate and DPPH.
Should make the weight of the security carrier discerned on its goods be equal to or greater than 0.1mg when making banknote, Valued Securities or sign, mark, to guarantee making it that enough mensuration sensitivity can be provided with coating of the present invention.Advantage of the present invention is as follows:
1, the making of coating simply, is easily gone and is with low cost.By above narration as can be known, coating of the present invention is to add the stable compound that certain its electron spin resonance spectroscopy has obvious distinguishing characteristics in the coating of now commonly used or special use.Be preferably manganous salt, its spectral line g=2.0063 has six contour spectral lines of △ H=86.25 Gauss.It makes no hell and high water.
2, made goods strong security.Its goods and common printed product there is no differently to the eye, but dark dark mark of the root of Dahurian angelica in it, and the identification of goods identified need specialized equipment makes it be easier to maintain secrecy.
3, adopt the mixture of two or more compounds as carrier among the present invention, its spectral line, spectrum shape are subjected to the influence of mixture composition and relative quantity, and multiple variation is arranged, and abundant scrambled can be provided, can satisfy the needs of making multiple banknote, security, sign, imitated very difficulty.
4, can discern security carrier can keep for a long time, and not changed by ectocine.Therefore, or the time limit of identifying for identification extremely long.
5, the False Rate of identification evaluation is extremely low.Because a kind of compound or certain its electron resonance spectrogram of mixture of a kind of constituent element composition are unique, so False Rate is extremely low.
6, another major advantage of the present invention is that the false proof and phoney that can be used as work of fine arts is differentiated.
