Description
Technical field
The present invention relates to a kind of writing ink, the method that particularly has the multiple anti-fake ink of memory cipher and detector and the ink marks that uses after this ink is write is detected.
Background technology
The anti-counterfeiting technology of existing ink has several forms, the one, be fluorescent material by in ink, mixing luminescent material, with ultraviolet light ink marks is shone then, utilize the fluorescence reverse signal to judge its true and false of identification, write e-Pointer as Chinese patent (application number) 96200746 anti-counterfeit anti-thefts with built-up type, it is to be constituted by the fluorescence lettering pen of the colourless writing ink that contains organic Ultraluminescence title complex and UV-light false-distinguishing machine.Write stealthy signature or password secret mark with it on file and valuables, anti-counterfeit anti-theft immediately with the check of the UV-light false-distinguishing machine on the pen, can be guaranteed the reliability that stealthy signature or password secret mark exist after writing effectively.Another part Chinese patent (application number) 90100949, manufacturing method of fluorescent ink are a kind of common manufacture method of writing the employed fluorescent ink of fountain pen that is.This ink adopts basic dyestuff, is that fluorescence has been encouraged agent with the polypropylene glycol, is solvent with ethanol, ethylene glycol, and adds emulsifying agent, sanitas and spices.When behind the fluorescent ink that forms the fluorescence color lake under certain proportioning and the pH value and make, this ink has bright in colour and certain fluorescence intensity, and water-fast, chemical resistant properties and fastness are good, and thermostability is high and the good advantage of writing smoothly property.The weak point of fluorescent ink is that this technology detects just whether fluorescent material is arranged in the ink marks, and such technology is still imitated easily, only needs to have mixed fluorescent material just in ink.Second kind of form is the heat discoloration ink, it is to add heat discoloration pigment in ink, and ink can change color when temperature changes, as Chinese patent (application number) 01108989, allochroic ink composition sensitive to temp comprises: at least one heat discoloration pigment and a vehicle.Wherein, heat discoloration pigment is heat discoloration microcapsule pigment, its particle dia is less than 1 micron, its temperature range is-10 ℃ to 100 ℃, and vehicle comprises the aqueous solution or the organic solution of tensio-active agent, dispersion agent, acid-base buffer agent, sequestrant, sterilant, sanitas and uvioresistant reagent." dyestuffs industries " 2002,39 (6) summarized variable color mechanism, discoloration and the range of application thereof of thermochromic material.The thermochromic material that is used for writing ink is that special-purpose chromogenic reagent, developer and desensitizing agent are dissolved in solvent.If desensitizing agent also is a solvent, then chromogenic reagent, developer are dissolved in solvent, become aqueous thermochromic material.The third form is to add other anti-fake materials in ink, as Chinese patent (application number) 93101826, denomination of invention: a kind of method for making, usage and purposes of writing, printing, (digest) with ink (printing ink) series the invention provides a kind ofly have that property is write, printing ink or ink series.Comprise its method for making, usage, purposes.The preparation method is water-base ink and the oil-based ink that is mixed with as one of raw material with cupric bromide, is the preparation of the elimination ink marks that is made into of one of raw material with Sulfothiorine, with and compound method separately.It is said that this ink marks can be clean with the special use of the present invention black agent that disappears, and removes fast.Also can heat and be permanently fixed firmly.Can be used for writing, in the anti-fake product such as drawing, watermark, mimeograph, secret writing, paper instruments encryption.Chinese patent (application number) 98103555, denomination of invention: a kind of manufacturing process of anti-fake jet ink, (digest) a kind of anti-fake jet ink manufacturing process is added particular matter as the special anti-counterfeiting material in the dyestuff of office ink-jet printer ink; After the ink payment that this technology is made is used, behind printing of inkjet printer figure code alphanumeric, can use special-purpose identification instrument to distinguish in printed picture and text, the number whether have these particular matters, and with this as the standard of distinguishing the true from the false, this method can strengthen anti-counterfeiting power in the office automation process.The 4th kind of form is the false proof mode that contains the transparent holographic figure that can write, as Chinese patent (application number) 97190450, denomination of invention: contain the anti-fake document of the transparent holographic figure that can write, (digest) such as bank converges the security document form of (propping up) ticket or other valuable documents and can contain the transparent holographic figure that can write or diffraction grating as false proof means.Hologram can be covered with whole file or wherein a part of, inserts other data of zone and file such as signature and inserts the district, for example parts such as date, name, numerical value.Patent (U.S.Pat 5267735) before the same inventor has adopted metalized holographic figure to these application, but can not xerox or micrography file because its reflectivity is high.This photomechanical printing problem can be resolved by using the transparent holographic figure that can write, and its allows that writing is carried out in legal application and xeroxs clearly, but can obviously find out when wanting to pretend to be for original paper and forge.By Corona discharge Treatment well known in the art or coat and hold ink material and can form and hold black upper surface.On the appearance of hologram China ink surface, write or impact printing and can partly cover hologram under these writings, also can make the embossed surfaces of hologram be subjected to etching, even ink is wiped or removed for a certain reason like this, also can stay writing, and it can not be changed.It can be anti-tampering using the hologram on this lamination or the Method Of Accomplishment of diffraction grating.
Above-mentioned several anti-counterfeiting inks or printing writing material respectively have relative merits, and the making processes that has is more responsible, and the antifalse effect that has is relatively poor, is cracked by the people easily.
Summary of the invention
In order to overcome the weak point that existing ink anti-counterfeiting technology exists, the invention provides and a kind ofly not only have memory cipher but also have the ink of multiple anti-fake function and the method that the ink marks that uses this ink to write is detected.
Anti-counterfeiting ink of the present invention is to realize like this, there is the anti-counterfeiting ink of memory cipher to comprise common ink, magnetic memory material, Infrared fluorescence material and ultraviolet fluorescent material, described magnetic memory material is a magnetic conduction good metal oxide compound, it can store the electromagnetism encrypted message of input and can preserve memory and can distinguish the electromagnetism encrypted message by instrument, this magnetic memory material comprises ferric oxide, manganese oxide, cobalt oxide, the ferric oxide, manganese oxide, the cobalt oxide that perhaps add rare earth material are as r-Fe
