Abstract
Atomic printing ink for forgery prevention with ultraviolet ray relates to a kind of permeability type atomic seal ink that is used for atom print, by carrier, defoamer, solvent and at least a absorb UV-light and can send the Ultraluminescence pigment of characteristic fluorescence formulated.Atomic printing ink for forgery prevention with ultraviolet ray is except that characteristics such as have general atomic seal ink trace fast drying, the shelf time is long, trace is clear, under the irradiation of suitable wavelength UV-light, trace can send bright-coloured fluorescence, is convenient to differentiate the true and false of trace, thereby has and prevent the function of forging.The present invention is specially adapted to infiltrate atom print and has anti-fraud functional seals with ultraviolet anti-fake atoms with manufacturing.
Description
The present invention relates to a kind of permeability type atomic seal ink and manufacturing process thereof that is used for atom print.
Atomic seal ink is gained the name because of atom print.Common seal and employed ink paste or stamp-pad ink are disconnected from each other, must make seal attach stamp-pad ink when impressing temporarily.Atom print is different with common seal, and its stamp-pad ink is to inject seal in advance, needn't attach stamp-pad ink when impressing temporarily.Therefore, atom print uses very convenient, and an oiling can be used more than ten thousand times.
The atomic seal ink that injects atom print mostly is permeability type atomic seal ink, and it is to be penetrated in the atom print rubber relief printing plate by suitable technology.Permeability type atomic seal ink is generally ground formulated through colloidal mill by carrier, pigment dyestuff, defoamer and solvent, wherein carrier must be can be painted material, as Viscotrol C, chlorinated paraffinic oil, synthetic resins etc.Pigment dyestuff is commercially available pigment of all kinds, and as red, bronze red, everbright fast red and EX-SF DISPERSE BLUE EX-SF 300 etc., the pigment that is adopted with common ink paste is identical.Just because of the pigment dyestuff that atomic seal ink adopts is identical with the pigment that common ink paste is adopted, so be easy to the same with common seal of atom print forged, the true and false of its trace is difficult to identification.
The objective of the invention is to obtain a kind of identifying stamp true and false that is easy to, can prevent to forge the permeability type atomic seal ink of seal effectively.
To achieve these goals, the present invention adds at least a Ultraluminescence pigment that absorbs UV-light and send characteristic fluorescence to make a kind of atomic printing ink for forgery prevention with ultraviolet ray in the composition of raw materials of general permeability type atomic seal ink; Perhaps in the composition of raw materials of general permeability type atomic seal ink, replace pigment dyestuff, to make a kind of stealthy atomic printing ink for forgery prevention with ultraviolet ray with at least a stealthy Ultraluminescence pigment.UV-irradiation atomic printing ink for forgery prevention with ultraviolet ray or stealthy atomic printing ink for forgery prevention with ultraviolet ray trace with suitable wavelength all can show bright-coloured characteristic fluorescence, thereby the trace of can distinguishing true from false rapidly, exactly, prevent to forge seal effectively.Be described in further detail below in conjunction with the technical characterictic of specific embodiment atomic printing ink for forgery prevention with ultraviolet ray of the present invention.
Atomic printing ink for forgery prevention with ultraviolet ray of the present invention still belongs to permeability type atomic seal ink, except that components such as carrier, pigment dyestuff, defoamer and solvent, has also added at least a Ultraluminescence pigment component that absorbs UV-light and send characteristic fluorescence in its composition of raw materials.The Ultraluminescence pigment that can be used as the atomic printing ink for forgery prevention with ultraviolet ray component has commercially available organic ultraviolet high-visibility pigment (as disperseing fluorescein 2LG and the bright B of Luo Da), inorganic Ultraluminescence pigment (as the zinc sulfate class) and metal complex Ultraluminescence pigment (as yttrium class fluorescent complex).
Be that carrier mixes the Ultraluminescence material and can obtain a kind of polymer Ultraluminescence pigment with the high molecular polymer, because the Ultraluminescence material is easy to disperse in high molecular polymer, its fluorescent effect is remarkable, so polymer Ultraluminescence pigment is the best Ultraluminescence pigment as the atomic printing ink for forgery prevention with ultraviolet ray component.
