Abstract

The present invention relates to an X fluorescent commodity anti-counterfeiting technology and a mark coating article thereof. The mark coating article on a commodity is irradiated by a high-energy X ray or a low-energy gamma ray to radiate a specific spectral line, and the true and false can be judged by contrasting radiation energy spectrums measured by an X ray energy spectrometer to standard spectrum lines of the mark coating article. The mark coating article of the present invention is a film coating agent or an adhesive which comprises an or a plurality of elements which can irradiate the high-energy X ray, such as glue containing elements of ammonium molybdate, lanthanum nitrate, etc. The anti-counterfeiting technology of the present invention has the advantages of strong invisibility, difficult discovery by counterfeiters, difficult reproduction, etc.

Description

A kind of X fluorescence commodity counterfeit prevention mark

The present invention relates to a kind of X fluorescence commodity counterfeit prevention mark, belong to the two wires anti-counterfeiting technology.

In the market at the anti-counterfeiting technology of goods marks, the consumer directly can discern, and to belong to a line false proof, as laser hologram image, and bar shaped etc., factories such as typographic(al) mark on anti-fake mark in this technology such as trade mark, the packing often can not oneself produce, and oneself is controlled.Some lawless persons often utilize this point to copy, and factory is difficult to identification.

The object of the present invention is to provide a kind of anti-false sign thing and method, by production manufacturer oneself preparation mark at the false proof trade mark of needs, marking place as bonding agent, use such as coating agent, sealing compound, it is disguised strong to utilize Special Equipment to check its true and false, factory can oneself control, and the adulterator is difficult to find.

Technical scheme of the present invention is achieved in that the false proof parts of need such as the trade mark marking at commodity are coated with false proof special mark thing, when scribbling the mark of mark with X or gamma ray projector irradiation, the characteristic spectral line that mark sends is by the detecting device receiving record, with the true and false of standard spectral line contrast with the judgement commodity;

Mark contain easily the special elements molybdenum that produced fluorescence by excitation of X-rays and occur in the commodity of not being everlasting, silver, lanthanum, gadolinium, neodymium etc. wherein one or more, other of mark consists of the organic solvent that only contains carbon, hydrogen, oxygen, nitrogen, bonding agent, coating etc.

The composition of X fluorescence commodity counterfeit prevention mark comprise polyvinyl alcohol (PVA), acryl resin, gum arabic, starch, dextrin wherein one or more, mark contain the sign metallic element be 0.01-0.1%.

Mark can be used as the bonding agent of pasting trade mark, is coated in the coating agent on the commodity marking, and commodity seal coating agent.

Describe content of the present invention in detail below in conjunction with embodiment and accompanying drawing.

Embodiment 1 trademark anti-counterfeit method a, X fluorescence antiforge method for commodities principle is among Fig. 1: 1, X or gamma ray projector 2, X or gamma-rays 3, mark sample part 4, X fluorescent radiation 5, detecting device 6, multichannel pulse scope-analyzer b, brand mark bonding agent (brand bonding made of paper) polyvinyl alcohol (PVA)-1,788 10% ammonium molybdate 0.01% silver nitrate 0.012% lanthanum nitrate 0.008% gadolinium nitrate 0.01% water surplus Fig. 2: be embodiment 1 brand mark bonding agent energy spectrogram c, false-proof detection method

Adopt anti-counterfeiting technology of the present invention; Its anti-false sign thing production manufacturer prepares on one's own account; Detect and preferably undertaken by metering quality testing department or commercial management department; X-ray source is operated mark position on the irradiation commodity in accordance with regulations, get final product with its energy spectrogram of X-ray energy spectrometer Measurement and analysis and the contrast of standard spectrogram simultaneously. embodiment 2: merchandise marks adhesive (papery brand bonding) dextrin 10% glycerine 0.5% ammonium molybdate 0.01% stannic chloride 0.05% neodymium nitrate 0.01% water surplus Fig. 3 is embodiment 2 brand mark adhesive power spectrums (being applied to hardboard behind) embodiment 3: merchandise marks adhesive methylcellulose 5% polyvinyl acetate 20% oxytol acetate 4% acetic acid dibutyl ester 2% gum arabic 5% stannic chloride 0.01% sodium iodide 0.08% lanthanum nitrate 0.02% water surplus Fig. 4 is embodiment 3 brand mark adhesive power spectrums. (be attached on the stainless steel products, cover lucite): embodiment 4:trade mark or marking filming agent (be suitable on commodity directly the sign overlay film of printing) acrylic resin 0.6% ammonium molybdate 0.01% stannic chloride 0.05% gadolinium nitrate 0.01% ethanol surplus Fig. 5 is embodiment 4 trade marks or marking filming agent power spectrum (aluminium coating goods) embodiment 5, commodity sealing compound film glycerine 15% gelatine 60% ammonium molybdate 0.01% stannic chloride 0.05% water surplus

The invention has the advantages that and do not destroy commodity sample, can be at the thicker trade mark back of the body The face coating detects rapidly accurately, and is disguised strong, and the adulterator is difficult to find, is difficult to Forgery and detection etc. Factory can control voluntarily, protection producer and operator's Interests, the while has also been protected consumer's interests.
