Abstract
The invention belongs to safety printing ink, by commercially available common printed printing ink add the fluorescence radiation material, can with the material of generation variable color of character eliminating liquid kind material or color development reaction and to play the auxiliary of adjusting the ink printing performance formulated.The dual-use function that can have anti-forging and anti-altering simultaneously, the anti-false sign of printing with it can send brightly painted fluorescence under UV-irradiation, then tangible variable color or color development can take place when running into the character eliminating liquid kind material.Therefore the anti-forging and anti-altering performance is all very reliable, and it is convenient, with low cost to produce.
Description
The present invention relates to a kind of printing-ink.
Bank note, security, bond, check or other similarly have valency bank note often to be forged or alter by the lawless person, and this has become the harmful greatly of current society.The existing method that prevents to forge valency bank note roughly is two classes.One class is to print the secret mark pattern with watermark on bank note, but watermark secret mark pattern still is easier to forge.Another kind of is to adopt safety printing ink.So-called safety printing ink is to add to prevent the material forged in common ink, as magnetic substance, ultraviolet ray or infrared absorbent (CN1013681B), the luminophore of forming by flash of light metallic compound and phosphorescent compound (EP253543B), reach the material (J03166276A) that fluorescence takes place under ultraviolet light irradiation, wherein first three plants substance because of the cost height, or make difficult, or reason such as anti-counterfeiting performance is not still good enough, Application and Development is still undesirable, it is then simple for production to add the fluorescence radiation material, cost is low, anti-counterfeiting performance is reliable, only need shine during check and tell the true and false at once, therefore become the main trend of exploitation safety printing ink with the ultra-violet lamp one of specific wavelength.The existing anti-safety printing ink of using instead that is coated with then is to add the material (J59064679A, J58157873A) that variable color or color development (redox reaction) can take place (its main component is for containing oxychloride and oxalic acid etc.) with the character eliminating liquid kind material in common ink.Yet existing anti-counterfeiting or the anti-function singleness that is coated with the safety printing ink of using instead, color developing effect is undesirable.
The purpose of this invention is to provide a kind of novel have false proof and/or anti-correction function, can select the discrimination performance, that manifest bright-coloured fluorescence, variable color or the tangible safety printing ink of color development.
The object of the present invention is achieved like this: the safety printing ink of anti-forging and anti-altering by commercially available printing-ink (A), fluorescence radiation material (B), can with the material (C) of generation variable color of character eliminating liquid kind material or color development reaction, and auxiliary (D) mix and form, the weight ratio of these component content is (A) 50～80%, (B) 0～20%, (C) 0～20%, (D) 0～10%.Change component (B) and/or content (C) and can select the safety printing ink of various anti-counterfeiting performances, exist simultaneously as (B) with (C), and when content changed in 5～20%, the safety ink of being prepared had good anti-counterfeiting and the anti-dual-use function of altering simultaneously; When (B)＞0, (C)=0 o'clock, this safety printing ink has only the anti-counterfeiting function; When (B)=0, (C)＞0 o'clock, then this safety printing ink has only the anti-function of altering.But, (B) and (C) can not be zero simultaneously.
All kinds of commercially available printing-ink that component (A) can select for use paper to use can be printed to such an extent that show red, yellow, blue, green, cyan or cryptomorphic anti-counterfeiting mark under visible light according to the color of selected (A).
Component (B) is selected the compound that can send fluorescence under UV-irradiation for use, as rare-earth complex (europium class complex compound or yttrium class complex compound or samarium class complex compound), toluylene system, imidazoles system, thiophene system, triazole system, imidazolone system, coumalin system or inorganic fluorescent chemicals (as ZnSCuCO, ZnSCu, MgWO
4, the rare earth mineral compound), according to selected (B) difference, under UV-irradiation, can send the fluorescence of different colours, wherein luminous more bright-coloured with rare-earth complex (as europium class complex compound or yttrium class complex compound or samarium class complex compound), ZnSCuCO.
Component (C) is selected for use and is run into the material that variable color or color development reaction (being redox reaction) can take place the character eliminating liquid kind material, as vulkacit D, 1-phenyl-3-imidazolidone, phenothiazines, methyl violet color lake, the colourless U.S. orchid of benzoyl, manganous salt, gallic acid, wherein obvious with the variable color or the color development of vulkacit D especially.
Component (D) can be selected for use and play the material of adjusting the ink printing performance, as BaSO
4, Al(OH)
2, CaCO
3, wilkinite, polyoxyethylene glycol, ink oil, Viscotrol C, Camellia oil, sweet oil, rapeseed oil, soybean oil, the Synolac of various performances, maleic acid resin, ketone acid resin, resol.
The advantage that the present invention compared with prior art has is: owing to added the fluorescence radiation material and with the character eliminating liquid kind material material of variable color or color development reaction can take place in the component of safety printing ink, therefore this safety printing ink can have anti-counterfeiting and anti-function of altering simultaneously, particularly adopt rare-earth complex or ZnSCuCO, the fluorescence that sends is more bright-coloured, adopt vulkacit D, variable color or color development effect are more obvious.
Safety printing ink of the present invention is applicable to various have valency bank note and analogues, particularly is applied on check and the invoice anti-counterfeiting, the anti-dependable performance of altering.
