Abstract
The invention relates to a water-based laser anti-counterfeit printing ink, comprising the following components by weight percent: 15-30% of deionized water, 15-30% of ethyl alcohol, 0.01-2% of defoamer, 0.1-4% of wetting dispersant, 20-40% of waterborne polyurethane, 5-20% of water-borne acrylic resin or 5-25% of pigment. The ink in the technical scheme has the effects of good adhesion, water resistance, oil resistance and the like after being printed, the laser anti-counterfeit pattern is protected, and different effects can be printed on the same laser pattern.
Description
Technical field
The invention belongs to paint field, specifically refer to a kind of water-based anodized aluminium packaging composite film chromatograph ink that is applied to packages printing industry.
Background technology
Antiforge laser holographic (laser anti-counterfeiting) technology is the anti-counterfeiting technology with development prospect of generally acknowledging in the world, is a kind of antifalse package printing material.It is the false proof requirement according to paper wrapper industry, the multinomial technology combination that laser hologram pressing mold, Computerized Photoetching, extraordinary plate-making, precise electrotyping thickness chemical industry, high precision are peeled off etc. to different subjects is first made transferable holographic plastics film and then is transferred on paper, makes laser hologram transfer paper.In China, mold pressing laser technology is early than within 1988, being applied to false proof field.Why this technology can be applied to false proof field, except the factor such as cheap, identification is convenient, is mainly because its extremely strong information supporting capacity technically.State when embossed hologram can be recorded holographic shooting, character, aftertreatment situation and the sensitive materials character etc. of optical element used, its complicated optical signature can not effectively be copied.Owing to thering is extremely strong information supporting capacity, for the high microphotography of ink printing method difficulty, just simple many for moulding laser holographic.
In the prior art, laser anti-counterfeiting adopts mould pressing technology more, once shaped, and advantage is to copy difficulty, and efficiency is higher, and shortcoming is to only have the antifalse effect of one deck, lacks in " rear area ".
Summary of the invention
The object of the invention is to create stable " rear area " for existing laser anti-counterfeiting, on laser anti-counterfeiting layer, print, improve the anti-counterfeiting performance of laser anti-counterfeiting.
The present invention is achieved by the following technical solutions:
A kind of aqueous laser anti-forgery ink, its composition is by weight percentage:
Further, described aqueous laser anti-forgery ink, its composition also includes 2～4% water-based wax by weight percentage.
Described water-based wax refers to aqueous polyethylene wax emulsion, is high density polyethylene waxes.
Described defoamer is not for containing organosilyl defoamer.
Described water soluble acrylic acid resinoid is acrylic emulsions, is polyacrylic high molecular polymer, and molecular weight is 8000-12000, and second-order transition temperature is 80-100 DEG C.
Described wetting dispersing agent is modified poly ester, and active ingredient is 39-41% by weight percentage, and solids content is 49-51% by weight percentage.
Described aqueous polyurethane is a kind of or two kinds of mixtures in polyaminoester emulsion, polyurethane-urea emulsion, vinyl urethane emulsion, polyisocyanates emulsion or blocked polyurethane emulsion.
Described colorant comprises one or both mixtures of water soluble dyestuffs or water-based paint.
The invention has the beneficial effects as follows:
The ink of the technical program prints on the basis of laser anti-counterfeiting layer, can protect laser anti-counterfeiting layer, has solved after the printing of laser anti-counterfeiting layer or thermoprint poor water resistance, poor solvent resistance, the poor problem of oil-proofness, the work-ing life of having improved laser anti-counterfeiting layer.
Can, by using different aqueous laser anti-forgery inks, on the basis that does not change radium-shine layer, changing, improved greatly the use range of laser anti-counterfeiting, improved cost performance, can there is multiple antifalse effect in a kind of radium-shine layer.
Can be used as the supplementary false proof of laser anti-counterfeiting, improved the antifalse effect of laser anti-counterfeiting, become the second protection of laser anti-counterfeiting.Realize the uniqueness of laser anti-counterfeiting.
