Abstract
The present invention relates to photographic anti-fake technology. After holographic pattern to be transferred is formed by hot pressing transparent plastic film with holographic metal mother board, the plastic film is adhered to photosensitive film on metal surface with the pattern surface facing the photosensitive film, the photosensitive film is cured with ultraviolet light, and holographic anti-fake pattern is formed on the surface of metal after the plastic film is taken down. The anti-fake pattern can not be torn down and transferred.
Description
The present invention relates to a kind of hologram pattern and be used for field of anti-counterfeit technology.
Originally holographic false proof generally can only generate pattern on vacuum aluminum-coated polyester flake, after again with the terylene security pattern with sticker on required anti-fake product, so this kind method is false proof professional not strong, but adhesive can paste mutually, say on the stricti jurise to there is no antifalse effect.As application number is that 93102704.7 Chinese patent " application of polypropylene screen hologram mould pressing technology and this film ", application number are that 92116660.0 Chinese patent " laser holographic pattern printing transferring method " all exists similar shortcoming.
Thereby the object of the present invention is to provide a kind of with the holographic false proof pattern directly be produced on object such as metal surface, can not tear-off, can not paste the holographic anti-fake method that plays better anti-fake effect mutually.
Technical scheme of the present invention is such.This holographic anti-fake method is characterized in that steps in sequence is: holograph and precise electrotyping method are produced holographic metal mother; Mother matrix is stamped into the transparent polymer plastic sheeting by hot-press method with hologram image and forms holographic former figure film; The cleaning objects surface, and coated one deck ultraviolet light photo-curing glue forms photo-conductive film; Holographic former figure thin-film information faces down to cover and is close on the photo-conductive film, and ultraviolet light makes its curing by on the holographic former figure film irradiates light sensitive film; Remove holographic former figure film.
Holographic anti-fake method of the present invention directly is produced on hologram pattern on the solid surface, can not tear-off, can not paste mutually, therefore antifalse effect is better, the hologram that is generated by light-sensitive emulsion is transparent, can keep the product true qualities combine with product firmly extremely strong, hardness is high, heat-resisting, survivable, shear resistance 15～20MPa after tested, heatproof-60～160 ℃, transmittance 90% is insoluble to common organic solvents.And transfer printing manufacturing process is very simple, process technology require low, produce also cost low, be convenient to its popularization.
Description of drawings:
Fig. 1. mother matrix and holographic former figure film synoptic diagram;
Fig. 2. make synoptic diagram 1;

Fig. 4. make synoptic diagram 3;
Fig. 5. make synoptic diagram 4;
Fig. 6. make synoptic diagram 5.
Below in conjunction with description of drawings embodiments of the invention are further described:
(1) adopt the holographic metal mother 1 of holograph and precise electrotyping explained hereafter, its Surface Microstructure as shown in Figure 1, promptly surface image is to be made of about 1 micron trickle striped at interval.
(2) mother matrix is by the method for hot pressing, hologram image is stamped into form us on the transparent polymer plastic sheeting and be used for the holographic former figure film 2 of transfer printing, and its surface structure and above-mentioned holographic mother are similar, as shown in Figure 1.
(3) suitably cleaning is made with absolute ethyl alcohol in transfer printing hologram pattern position, metal surface, be mixed with ultraviolet light photo-curing glue by glue and initiating agent component, drawn and dropped on object 5 metal surfaces with injection needle 4 or similar appliances, shakeout the photo-conductive film 7 that forms one deck glue, it is better generally to be controlled at the interior thickness of 2-10um, as shown in Figure 2.
(4) holographic former figure thin-film information face 3 sticks facing to glue layer photo-conductive film downwards, and, the bubble between film and the glue-line is discharged, and make glue-line evenly be full of the entire image surface with pressure head or seaming roll 6 pressurizations, this moment, hologram image should be can't see in the surface, shown in Fig. 3,4.
(5) place ultraviolet light irradiation curing down, about 10-15 second set time, the concrete time decides on the light source power, in solidification process, hyaline membrane for moulding approaches in the pressure process if there is a small amount of glue to overflow image range in subsides, can adopt the two-stage cure method to clean glue, because ultraviolet light photo-curing glue has anaerobic, promptly the drop curing rate that directly contacts with air is slow, can adopt earlier image section precuring, take out after several seconds, wipe the uncured glue in outside with absolute ethyl alcohol after, the regelate method keeps clean image again.For moulding hyaline membrane not, during use if having a small amount of glue overflow can be after primary solidification with cotton fine, add small amount of acetone, carefully remove the surplus glue-line, curing forever again, as shown in Figure 5.
(6) throw off the surface transparent film and can see hologram image, do suitable cleaning in case of necessity, as shown in Figure 6.
Claims (4)
1. holographic anti-fake method is characterized in that steps in sequence is:
(1) holograph and precise electrotyping method are produced holographic metal mother (1);
(2) mother matrix is stamped into the transparent polymer plastic sheeting by hot-press method with hologram image and forms holographic former figure film (2);
(3) cleaning objects surface, and coated one deck ultraviolet light photo-curing glue forms photo-conductive film (7);
(4) holographic former figure thin-film information face (3) covers downwards and is close on the photo-conductive film;
(5) ultraviolet light is by making its curing on the former figure film of the holography irradiates light sensitive film;
(6) remove holographic former figure film.
2. holographic anti-fake method as claimed in claim 1 is characterized in that described photo-conductive film thickness 2-10um.
3. holographic anti-fake method as claimed in claim 1 is characterized in that the former figure film of described holography covers downwards to be close on the photo-conductive film surface with the pressure head pressurization, the bubble between film and the glue-line is discharged, and make glue-line evenly be full of whole patterned surfaces.
4. holographic anti-fake method as claimed in claim 1 is characterized in that described curing employing regelate method, and first precuring is wiped after the taking-up and overflowed glue, more permanent curing for the second time.
