Abstract
The anti-fake stamp pad ink and printing ink are produced with marketable pigment, synthetic resin, vegetable oil, mineral oil, high-boiling point solvent, stuffing and ink oil and through mixing with special ong wavelength phosphor powder and short wavelength phosphor powder and other special preparation process. It shows lone specific color under the irradiation of long wavelength, 365 nm, UV and shows and other specific color under the irradiation of short wavelength, 254 nm, UV. The anti-fake stamp pad ink is suitable for use for all varieties of stamp and the anti-fake printing ink is suitable for use in printing various securities, bills and similar matters, especially check and invoice. The products of the present invention have excellent anti-fake effect.
Description
The invention belongs to stamp-pad ink and printing ink.Be called length ripple anti-counterfeiting stamp ink and anti-forgery ink particularly.
Paper certificate, check and various Valued Securities are often forged, are altered and alter by the lawless person, and this has become current social one big public hazards.The method of the existing Valued Securities that prevent to forge, alter roughly has two classes.One class is to adopt anti-counterfeiting stamp ink, cover content (for example cheque sum) and seal impression (for example finance seal, legal person's chapter) and goes up and realize purpose false proof, that prevent correction filling out.Another kind of is to adopt safety printing ink, goes up in printing (for example banknote, passport, check) in kind and realizes preventing counterfeit printing.
It is a kind of conventional means that fluorescence stamp-pad ink and printing ink are used for false proof purpose, but is the single wavelength fluorescence falsification preventing, does not also have the report of length ripple anti-counterfeiting stamp ink and anti-forgery ink.Along with the raising of social scientific and technological level, offender's the impetus is becoming increasingly rampant, and therefore, the technology content and the counterfeit difficulty that strengthen anti-fake product are imperative.
The purpose of this invention is to provide a kind of false proof, anti-correction and anti-adulterium function that have, have the anti-counterfeiting stamp ink and the printing ink that show bright-coloured tenebrescent.
The object of the present invention is achieved like this: anti-counterfeiting stamp ink and printing ink are mixed the process physical process and are formed by commercially available pigment, synthetic resins, vegetables oil, mineral oil, high boiling solvent, filler and stand linseed oil with special-purpose long-wavelength fluorescence powder (A) and shortwave fluorescent material (B) etc.
Component A and B select the compound that can send fluorescence under length ripple UV-light for use, for example rare-earth complex (europium class complex compound, yttrium class complex compound, terbium class complex compound) and inorganic fluorescent chemicals, different according to selected component A with B, under length ripple UV-irradiation, can send the fluorescence form and aspect of different colours.For example, under long wave ultraviolet (365 nanometer) irradiation, show certain particular color fluorescence (for example, europium class complex compound shows red fluorescence); Under short wave ultraviolet (254 nanometer) irradiation, show another kind of particular color fluorescence (for example, terbium class complex compound shows green fluorescence).
The advantage that the present invention compared with prior art has is: owing in anti-counterfeiting stamp ink and ink component, added long wave and shortwave fluorescence radiation material simultaneously, show the color changeable effect of two waveband, this is of paramount importance.
Anti-counterfeiting stamp ink of the present invention is suitable for all seal kinds, for example, and ink pad seal, Turnover stamp, permeating seal etc.; Anti-forgery ink is applicable to various security, bill and analogue, particularly is applied on check and the invoice, and anti-counterfeiting, the anti-performance the best of altering are the effective means of taking precautions against and fighting crime.
