Description
Technical field
The utility model relates to false-proof film, is specifically related to a kind of false proof thermoprint film of angular color change with polarization color changeable effect.
Technical background
Growing along with commodity economy, counterfeit and shoddy goods flood market, and the people's life has been caused very big harm, and the anti-counterfeiting technology of commodity and incrustation have caused people's generally attention.Having a kind of in the existing anti-counterfeiting technology is to adopt blanching seal technology with holographic laser film, golden aluminizer, the silver color aluminizer shifts thermoprint on product or its packaging material, and the thermoprint technology is very universal at present, and golden film, the silver color film, holographic laser film is seen everywhere on market, does not have anti-fake effect substantially.Also has a kind of optic metachromatic false-proof film at present, it is the principle of utilizing the interference of light, utilize high-grade takeup type coating machine on thin polymer film, repeatedly to deposit the different refractivity material and generate, but its production technology is comparatively loaded down with trivial details, equipment drops into higher, simultaneously, domestic existing several family units can produce similar products.
Summary of the invention
The utility model provides a kind of false proof thermoprint film of angular color change with polarization color changeable effect, to overcome the above-mentioned defective that prior art exists.
The false proof thermoprint film of angular color change with polarization color changeable effect of the present utility model, comprise angular color change functional layer and gold stamping glue-line that polymer film layer, release layer, optical orientation layer, angular photochromic material are made, release layer is arranged on a side of polymer film layer, the optical orientation layer is arranged on the opposite side of release layer, the angular color change functional layer that angular photochromic material is made is arranged on the opposite side of optical orientation layer, and gold stamping glue-line is arranged on the opposite side of the angular color change functional layer that angular photochromic material makes.
Said polymer film layer is as thermoprint rolling base material, adheres to other functional layer, and the effect of said release layer is when thermoprint, and polymers function layer and other functional layer are broken away from;
The material of said optical orientation layer is that the polyimides by modification forms through linear uv radiation curing, and its effect is to provide oriented layer for aligning of angular photochromic material.
Said angular color change functional layer is a kind of angular photochromic material, make its pattern or literal present light angle color changing effect, promptly along with the viewing angle difference of human eye, present two kinds of set, distinct colors about 0 ° of normal direction with on about 30 ° of normal direction, simultaneously, if observe by polarizer, then its pattern or literal are vanished from sight;
Said gold stamping glue-line is polyurethane, polyethylene or the random polypropylene that is dissolved with black or other dark dye, and gold stamping glue-line cannot not be sticking at normal temperatures, shows that under blocking point viscosity is transferred to product with the angular color change functional layer or it is packed.
The utility model is preparation like this:
First-selection adopts coating process well known in the art with release layer, be coated on the polymer film layer, then with optical orientation layer roller coat on release layer, penetrated 2～20 minutes with linear UV illumination, make it to take place photocured cross-linked reaction, (light source adopts 200～500W mercury xenon lamp to the oriented layer that formation aligns, and 280nm～330nm place polarisation power density is 1.2～8mw/cm
2); The chirality prepolymer is coated on this oriented layer, the chirality prepolymer aligns along oriented layer, penetrated 2～10 minutes with UV illumination, (light source preferably adopts 300～800W mercury xenon lamp, and the intensity at 280nm～350nm place is 1.5～15mw/cm to solidify the functional membrane that obtains having light angle color changing effect
2); The gold stamping glue-line of coating one deck on the angular color change functional layer obtains false-proof film described in the utility model thus again.
The utility model is because the characteristic that its angular color change functional layer has, make its pattern or literal present light angle color changing effect, promptly along with the viewing angle difference of human eye, present two kinds of set, distinct colors about 0 ° of normal direction with on about 30 ° of normal direction, simultaneously, if observe by polarizer, then its pattern or literal are vanished from sight.On product or its packing, pattern or literal are beautiful in colour, more are difficult to by counterfeit with this film article thermoprint, and popular antiforge function is strong.
The false proof thermoprint film of the angular color change with polarization color changeable effect that obtains by the utility model, variable color is obvious, identification easily, having the two wires anti-counterfeiting characteristic that is different from the optic metachromatic anti false film for preparing according to interference of light principle (observes by polarizer, the angular color change picture and text disappear), forge difficulty, thereby reach effectively false proof effect.
