Description
Technical field
The present invention relates to Application in Anti-counterfeiting technical field, particularly relate to a kind of cigarette anti-counterfeit ink.
Background technology
At present, false proof printing ink is an integral part in anti-counterfeiting technology, anti-forgery ink refers to have anti-fraud functional ink, this ink is normally made up of colorant, low-melting ink vehicle and ink addition agent, in ink vehicle, namely adds the anti-fake material of property and the special printing inks processed through special process.Why it can be false proof, is to utilize in ink to have the colorant of specific function and low-melting ink vehicle to come false proof.Nowadays, in the field of many anti-counterfeit printings, the use of false proof printing ink widely, as on the anti-counterfeit printing of various ticket, document, trade mark and mark etc., all uses false proof printing ink.This also mainly implements the features such as convenient, with low cost, disguised better, bright in luster because false proof printing ink has anti-counterfeiting technology.The ink that the anti-counterfeit printing of domestic and international exploitation uses has reached tens kinds, letterpress inks, gravure printing ink, stencil printing ink, lithography (offset printing) ink and aqueous flexible plate printing ink etc. can be divided into by printed form, paper printing ink, tin printing ink, news ink, ink used for plastic etc. can be divided into again by stock difference.
Ink anti-counterfeiting technology is the technology that in bill anti-counterfeit, Valued Securities and trade mark packaging field, practicality is very high, can meet the requirement of a popular line anti-counterfeit recognition, also can meet two wires, the senior expert of three lines, the discriminating of administrative authority, the requirement of supervision.The mechanism that anti-forgery ink fades mainly contains two aspects, and once being use to meet the ink remover pigment that can fade, as some slag dyestuffs etc., two is use the low-melting ink vehicle running into the just energy variable color of ink remover or some other chemical substance as xenol etc.Two kinds of methods can obtain satisfied effect.In anti-forgery ink, add fluorescent material, the effect of its anti-counterfeit package can be better.
But the anti-forgery ink adopted at present mostly exists that cost is high, inspection is inconvenient, or there is printing quality and do not meet the demands, the problems such as the color and luster after printing is of poor quality.

Adopt the cigarette anti-counterfeit ink of the present embodiment, prepare convenient and swift, cost is low, good concealment, bright in luster, inspection is convenient.
Embodiment two
The cigarette anti-counterfeit ink of the present embodiment comprises the raw material of following weight proportion: resin 18%; Glycerin monomethyl acrylic ester 37%; Light resin type flexographic ink 17%; Propylene glycol methyl ether acetate 6%; Temperature variable pigments 6%; Pearly pigment 3%; Solvent 10%; Flow agent 1%; Dispersion agent 3%.
Improve as to the one of technical scheme of the present invention, described resin is acrylic resin, described solvent is ethyl acetate, described flow agent is polydimethylsiloxane, described dispersion agent is polyethylene glycol type polyvalent alcohol, described pearly pigment is lead hydrogen arsenate, and described flow agent is polydimethylsiloxane.
Adopt the cigarette anti-counterfeit ink of the present embodiment, prepare convenient and swift, cost is low, good concealment, bright in luster, inspection is convenient.
The warm variable pigments adopted in the specific embodiment of the invention, also referred to as temperature change powder, heat discoloration powder, temperature-sensitive powder, heat discoloration pigment.It can be that temperature reddens, temperature flavescences, Wen Bianlan, temperature turn bright red, warm change golden red.Heat discoloration pigment is prepared by electron transfer type organic compound system.Electron transfer type organic compound is the organic chromophoric system that a class has special chemical structure.At a certain temperature, because transfer transport makes this organic molecular structure change, thus color transition is realized.Temperature variable pigments of the present invention can use any one disclosed in prior art to be applicable to temperature variable pigments of the present invention, also can use commercially available prod.
Show certain particular color under anti-counterfeiting ink for cigarette packets normal temperature of the present invention, after heating, color disappears and becomes colorless, and return to original color immediately after cooling, change procedure is reversible.The large paper of warm temperature is at about 40-50 DEG C.Compared with prior art, anti-forgery ink of the present invention can be exclusively used in cigarette filter and outer packaging, and main base material is tipping paper, enamelled paper.Mode of printing is offset printing or gravure.Anti-forgery ink of the present invention belongs to temperature sensitive ink, at a certain temperature, achieves colourless change coloured, coloured bleach.The present invention, is obtained by blending dispersion, grinding for starting material with resin, warm variable pigments, filler, auxiliary agent, solvent.Its reasonable recipe, cost is low, has the features such as easy to operate, look becomes sensitive, stable performance.Above-mentioned materials obtains anti-forgery ink by the technique such as blending dispersion, grinding.Gravure mode is adopted by anti-forgery ink to be imprinted on base material enamelled paper.Result is shown as large red at normal temperatures, and disappearing through color after to about 50 DEG C of heating becomes colorless, and returns to large red immediately, prove that its change procedure is reversible after cooling.
The modulation of heat-sensitive colour-changing ink of the present invention must use the resin of high solid content low-viscosity (low polymerization degree or lower molecular weight), could obtain good result like this.The tolerance of temperature variable pigments pigment to different solvents is different, soak in some solvent and also can not affect its discoloration in 6 months, but other solvents littlely can corrode microcapsule top layer and infiltrate that it is inner several within a few week, make taking off of the discoloration even completely dissolve of pigment.After evaporation of the solvent, this taking off of discoloration some can partly recover, some is completely expendable.In general, comparatively large to the erosion destruction of camouflage paint containing the solvent below 3 carbon atoms, very little on the impact of pigment containing solvents more than 6 carbon atoms.In addition, the erosion action of solvent can be more obvious at a higher temperature.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
