Near infrared absorption anti-counterfeiting ink
Technical field
The present invention relates to a kind of near infrared absorption anti-counterfeiting ink, belong to the anti-counterfeiting printing technology field.
Background technology
Valued Securities, bill, famous-brand and high-quality trade mark are often forged, altered and alter by the lawless person, and this has become current one big public hazards, and existing anti-forgery ink is single antiforge function, and is with low content of technology, and be easily imitated.Along with the raising of social scientific and technological level, offender's the impetus is becoming increasingly rampant, and technology content and the counterfeit difficulty of strengthening anti-fake product are imperative.
Summary of the invention
For overcoming with low content of technology, easy imitated, the shortcoming that anti-counterfeiting power is low of existing anti-forgery ink, the invention provides a kind of printing ink with near-infrared absorption anti-counterfeiting function, this anti-forgery ink is with high content of technology, counterfeit cost is big, anti-counterfeiting power is high.
The technical scheme that technical solution problem of the present invention is adopted is: add the mixed near infrared absorption anti-counterfeiting ink of making of near-infrared absorption anti-counterfeiting material by commercially available pigment, synthetic resins, vegetables oil, mineral oil, filler, stablizer, auxiliary agent, its composition proportioning is:
Near-infrared absorption anti-counterfeiting material 20-40%
Pigment 10-20%
Synthetic resins 30-40%
Vegetables oil 3-5%
Mineral oil 3-5%
Filler 5-25%
Stablizer 3-5%
Auxiliary agent 5-15%
Near-infrared absorption anti-counterfeiting material among the present invention is meant that absorbing wavelength is at 700-1100nm near infrared absorption material.Approaching colourless with the near infrared absorption anti-counterfeiting ink that this material is made, be suitable on various security, bill, trade mark and analogue, carrying out the printing of the sightless invisible-bar-number of all kinds of naked eyes, disguised strong, can effectively prevent duplicating, counterfeit.Printed invisible-bar-number can use special-purpose code reader to read, and identification is simple, is convenient to promote.
Embodiment
Near infrared absorption anti-counterfeiting ink of the present invention is to add the near-infrared absorption anti-counterfeiting material to mix in commercially available pigment, synthetic resins, vegetables oil, mineral oil, filler, stablizer, auxiliary agent etc., and the composition proportion of above-mentioned various materials is as follows:
Near-infrared absorption anti-counterfeiting material 20-40%
Pigment 10-20%
Synthetic resins 30-40%
Vegetables oil 3-5%
Mineral oil 3-5%
Filler 5-25%
Stablizer 3-5%
Auxiliary agent 5-15%
Above-mentioned near-infrared absorption anti-counterfeiting material is meant the near infrared absorption material of absorbing wavelength at 700-1100nm.
The concrete production process of this near infrared absorption anti-counterfeiting ink is as follows: produce 10 kilograms of anti-forgery inks for every batch, in above recipe ingredient ratio, get near infrared anti-fake material, pigment, synthetic resins earlier and stir into pulpous state, obtain component 1 below 15 microns being ground on the three-roll grinder; Vegetables oil, mineral oil, filler, stablizer, auxiliary agent are mixed through being ground to the component 2 of acquisition below 15 microns on the three-roll grinder; Component 1, component 2 are mixed on three-roll grinder, can obtain near infrared absorption anti-counterfeiting ink.
