Describe hologram layer, the retroreflecting layer of feature among the present invention below in detail.Hologram layer
Fig. 2 is the general preparation method's of expression hologram a key diagram.Figure is like this illustrated the general preparation method of hologram.
Shown in Fig. 2 (a), shine objects 12 with coherent light 14, write down the reflection wave that comes out from object with photosensitive record medium 16.From then on the reflection wave that object is come out is referred to as object wave 18.Place near object with photosensitive record medium 16 record object waves 18 time and send with the light source 20 of the light of coherent light 14 same wavelength etc., its light is not directly delivered to photosensitive record medium 16 by object.This light is referred to as with reference to ripple 22.In photosensitive record medium 16, note when carrying out by object wave 18 and and interference figure that form overlapping with reference to ripple 22.This interference figure is the response of 16 pairs of light intensity of photosensitive record medium no longer just, and it has comprised the object wave amplitude and the complete information of two aspects mutually.
This interference figure is different fully with original object, but the irregular pattern of meticulous striped.Shown in Fig. 2 (b), these photosensitive record medium 16 existing shadows, from with reference ripple 22 same angles with reproduced light 24 irradiation of identical wavelength now shadow holographic Figure 16 ' time of photosensitive record medium 16, see through the film that has write down interference figure photo reversal the picture 26 of object 12, observer 28 can resemble object 12 and observe picture 26 existing.
The photosensitive record medium be with photoresist with concavo-convex the note interference fringe of thermoplastics with the surface, and the concavo-convex thus relief type etc. of making, this makes a large amount of productions of hologram become possibility.
Also have, can make the matrix interference figure to the hologram made from actual object with computing machine etc.This interference figure is recorded in transparent material etc. just made and above-mentioned same hologram.
Counterfeit-proof binding mark of the present invention is attached on the goods, can not resemble shown in Fig. 2 (b) from the inside irradiation reproduced light.It is to take to establish reflection horizon 30 in the inside of hologram like that shown in Fig. 2 (c) to constitute, and the light from the face side irradiation is reflected from the inside, thereby make regeneration hologram image 26 become possibility.
That there is an evaporation light reflective metal in the reflection horizon or the evaporation metal oxide, when 100% evaporation light reflective metal, can almost completely reflect the light that incides hologram, but the reflection horizon of the evaporation metal oxide transparency is high, becomes translucent until transparent hologram sheet.
The hologram layer 4 of the present embodiment is to carry out the transparent holographic sheet that lamination forms by the reflection horizon of the hologram embossed layer that adds the hologram embossment, evaporation metal oxide.
Such as previously described, be the regeneration hologram, though must use the light of identical wavelength when writing down, the color fringe hologram is the hologram with the renewable image that goes out to regenerate of white light.Since the transparent holographic figure layer 4 of counterfeit-proof binding mark of the present invention be play the color fringe hologram when shining with white light like that as described above and under white light the also hologram of renewable image, therefore do not damage the outward appearance fine arts of goods when being attached on the goods as the mark of false proof purpose, but also improved the outward appearance fine arts of goods.
The character that has as hologram changes when record when writing down with respect to the angle of object light or direction with reference to light, has just changed born again regeneration image when changing the angle of reproduced light of irradiation or direction when regenerating so.
Fig. 3 has illustrated that hologram regeneration picture and object light follow the key diagram with reference to the relation of the angle of light.
As Fig. 3 (a) institute example, be that 20 degree come record with object light 34 with angle during the hologram image of record object 32 with reference to light 36, the permission incident angle of the reproduced light of the hologram that obtains this moment regenerating is spent with reference to angle of light degree ± 5.Then, shown in Fig. 3 (b), the record object 32 of (a) being become object 38, is that 35 degree come record with object light 40 with angle with reference to light 42, the object light 34,40 in the (a) and (b), all is identical with reference to the wavelength of light 36,42.Hologram by such preparation, such shown in (c), use with (a) with reference to light 36 same angle ± during reproduced light 44 irradiations in the 5 degree scopes, just the regenerated regeneration image 46 of the object 32 that write down in (a), shown in (d), use with (b) with reference to light 42 same angle ± during reproduced light 48 irradiations in the 5 degree scopes, the regeneration image 50 of the object 38 that is write down in regenerated (b).
Further, when irradiating angle is identical, shown in (e) like that, when the direction of illumination of object light 52 is observed, if the direction of illumination that changes with reference to light 54 writes down the object that is write down, just can bear rather different figures again by the direction of illumination that changes the reproduced light that is shone.
Used the transparent holographic figure layer 4 of such multiple-exposure in the present embodiment.Just regenerate the regeneration image different by irradiating angle that changes reproduced light and direction of illumination.Can when preparing mark, become difficult and make the manifolding of its hologram and make its duplicate with apperance fine arts for this reason.
Though hologram has various record forms, the record form of renewable hologram image under the existing white light in the present embodiment also can be with the Fourier Tranform hologram of saying below.
Of the present invention being further characterized in that, the hologram that can not observe under white light regeneration picture is multiple-exposure in hologram layer.Hologram layer 4 in the present embodiment is when using laser radiation, and as the effect of Fourier Tranform hologram, the hologram image of having regenerated under white light disappears, and carries out multiple-exposure by laser with the form of regenerating hologram regeneration picture new.
Fig. 4 is the preparation method's of Fourier Tranform hologram a key diagram.
Method shown in Fig. 4 (a) is used is that object 56 that hologram is write down is recorded in the planar object resemble the lantern slide.The object 56 that hologram write down is placed focal plane place, front side apart from 58 1 f focal lengths of prism,, recording materials 62 are placed rear side focal plane place apart from 58 1 f focal lengths of prism with parallel laser 60 photographs.Also use directional light with reference to light 64.Ji Lu hologram has produced the Fourier Tranform pattern of the object that writes down on its recording materials face like this.
Though the situation that has been to use prism that Fig. 4 (a) illustrates does not use prism can make the Fourier Tranform hologram yet.
In recording method as shown in Figure 2, record object 66 shown in Fig. 4 (b) is in the occasion away from recording materials 68, or shown in Fig. 4 (c) like that being configured to and recording materials 74 equidistant D places with reference to light source 70 and object light source 72, the hologram that is write down has the feature same with the Fourier Tranform hologram.The former is referred to as the Fu Langhuofa hologram, and the latter is referred to as not have prism Fourier Tranform hologram.
The Fourier Tranform hologram is shown unique character because of its record portrait by 2 exposures.Among Fig. 4, after an object is recorded, replace to other object record again.Such 2 space images that heavily obtain during the hologram of exposure of regenerating are amplitude sums of 2 objects.Also have, use position photo arbitrary time in 2 records, when making position with reference to light only change half wavelength mutually, then obtained the space image of the difference of vibration of 2 objects.
The Fourier Tranform hologram is renewable when the regeneration of the corrugated identical with reference light to go out space image, even but have the also motionless character of its picture of mobile hologram in face this moment.So, in the present embodiment, do not carry out promptly using laser radiation no longer to bear the feature of regeneration picture by the reproducible color fringe of white light hologramization so this Fourier Tranform hologram has yet.The retroreflecting material layer
Follow the retroreflecting layer of the feature that further specifies counterfeit-proof binding mark of the present invention.
The retroreflecting layer of counterfeit-proof binding mark of the present invention is that interference material layer and the transparent beads that the mica powder of the Li-Co-Ti system complex oxide that produces the colored interference look by being covered is constituted formed.
Fig. 5 is that the summary of an embodiment of retroreflecting layer of the present invention constitutes sectional view.In this embodiment, retroreflecting layer 78 is Li
2CoTi
3O
8Lining mica 82 is configured on the base material 80, transparent beads 84 is gone up in permutation configuration thereon again.Though the base material that is constituted with reflective metal plate or reflective metal evaporation layer in the common retroreflecting material, among the present invention base material no matter be have deny reflexive can, cloth or film are good.This is owing to interfere used Li in the material layer
2CoTi
3O
8Lining mica powder has high refractive index and has sufficient light reflective.
Transparent beads 84 plays the light that makes incident, and it returns the effect that direction that light enters generally along incident light is returned when returning.The interference material layer that produces the colored interference look always be with sheet metal or, have retroreflecting material that the argentum reflecting layer, coating etc. of metal evaporation layer only reflect the light of specific wavelength to constitute and give color, retroreflecting material of the present invention then utilizes the interference of light effect and gives recurrence light with tone.For this reason, the utilization factor of light is high.
In the interference material layer in the present embodiment, as previously mentioned, used Li
2CoTi
3O
8Lining mica 82.The light of being overflowed for transparent beads 84 is at Li
2CoTi
3O
8The surface of coating 86 of lining mica 82 and the surface of mica 88 are reflected, because of the optical path difference of the bed thickness of coating 86 produces interference.For this reason, adjust Li
2CoTi
3O
8Bed thickness just can obtain tone arbitrarily.Especially, because the material of generation interference color is to chemistry, the stable dead matter of light: Li
2CoTi
3O
8The lining mica is so can obtain the retroreflecting layer of thermotolerance, anti-timeliness excellence.The such retroreflecting material of counterfeit-proof binding mark of the present invention, given colorful tone by interfering material, sexually revised the optical path difference that produces along the incident direction of light by retroreflecting in interfering material, this has just prevented to interfere the variation of the color that material presented.
Owing to used such retroreflecting material to make that further the raising confidentiality becomes possibility.Retroreflecting layer among the present invention does not produce interference color at the interference material that general illumination such as fluorescent light and sunray etc. return in the reflecting material under the light source irradiation usually.This is because the direction of light of incident is dissimilar, only from various direction incidents, has been mutually offsetted from the interference color that light produced of direction incident separately.Under common light, retroreflecting layer of the present invention presents the tone of interfering all outward appearance looks of material layer thus.
Yet the directivity that makes incident light is during with the certain orientation irradiation of unanimity, and interference material layer of the present invention just presents the color that is produced because of the incident interference of light.This directivity is referred to as straight line light with the light of the certain orientation of unanimity.Though straight line is the light of light direction unanimity only, there are various wavelength in it, so be different with laser beam.
Can be by outward appearance look of adjust interfering the used interference material of material layer and the tone difference of interfering the thickness of the coating of material that interference is presented, the tone that the retroreflecting layer is presented can present different tones with the light of irradiation.
Like this, employed in the present invention retroreflecting layer presents different tones under normal light and straight line light, and therefore just can differentiate it to a certain extent by the tone that linear light radiation presented is genuine piece or counterfeit.And, only under general normal light, not observing mark of the present invention, the people beyond the relevant personnel misknows the variation of tone by such irradiate light, so it also is difficult to be forged in the effect that has with the same hidden information of hologram.
More than describe the various piece of mark of the present invention in detail with the embodiment of counterfeit-proof binding mark of the present invention.
Counterfeit-proof binding mark of the present invention is considered its cohesive according to its used goods and uses thereof, thermotolerance, weatherability, resistance to chemical reagents etc., select for use suitable material to form each layer, operable have a good quality paper, art paper, the mill coated paper, Japan paper, cartridge paper, general printing such as E level, UV printed, ultraviolet varnish, ultraviolet coating paper, the news coated paper, Polyvinylchloride (PVC), polypropylene (PP), the stationeries such as various laminated papers that polyethylene terephthalate (PET) etc. is made, soft, ethene such as hard and foam ethene, acrylonitrile-butadiene-styrene (ABS) (ABS), acrylonitrile-styrene (AS), high impact polystyrene (HiPS), AC, PP, plastics such as PET, originally refining, photograph album, T-sympathizes, various fibers such as cloth products, leather, glass, metal, various starting material such as carpenter.Be that the used starting material of the present invention are not limited to cited various again.
Next the Production Example of counterfeit-proof binding mark of the present invention is described.Production Example 1
Use multiple recording by the interference fringe of the color fringe hologram of the renewable image that goes out to regenerate of white light with only be used as the benchmark hologram by red laser can regenerate the recording materials of interference fringe of Fourier Tranform hologram of regeneration image, make regenerate the equally hologram film of image of renewable and benchmark hologram by record and the same interference fringe of benchmark hologram.
Evaporation titania on this film and make the transparent holographic sheet.
This transparent holographic sheet be under white light from white light mainly by the hologram sheet of the renewable image that goes out to regenerate of green light, and just can observe the hologram of 4 kinds of different images of regenerating when changing the direction of illumination of reproduced light, and when only shining, just can only observe a kind of specific regeneration image with red laser.
Then, be base material with white acrylic fiber cloth, Li on the screen printing in the above
2CoTi
3O
8The lining mica mixes the transparent painted screen printing printing ink that obtains with acrylic resin solution, the last refractive index of distribution thereon is 1.9 200～250 purposes transparency glass granules again, do not buried such one more than half ball of particulate and adhered to drying overlappingly, made the retroreflecting layer.That this retroreflecting layer presents under normal daylight is green～blue outward appearance look, under straight line light, present the interference color of red～purple.
Amass layer by layer and make counterfeit-proof binding mark resembling the transparent holographic sheet made respectively above-mentioned and retroreflecting separately.Fig. 6 is the sectional view of the counterfeit-proof binding mark finished.Referring now to Fig. 6 its preparation process is described.
Resulting mark is attached on the goods back observes, when use white light source, under the state of the hologram image of not regenerating during incident ray, observe the tone of green～blueness that the interference material of retroreflecting layer presents.When goods are tilted to the white light incident direction, when incident angle is changed, then observing the catoptrical while of the peculiar rainbow of color fringe hologram, also observe regeneration image by green glow regeneration.During further with all angles and direction incident white light, just can in transparent holographic figure, observe different regeneration images.Fig. 7 has represented the regeneration picture with white light regeneration.
The arrow that Fig. 7 (a) and (b), (c), (d) put down in writing is respectively represented the direction of illumination of incident light.Just anti-fake mark, observe 4 kinds of different regeneration images during from such different directions incident white light.(a)～(c) because of being Word message as bidimensional image regeneration, the stereopsis because hologram can be regenerated is so flying out from the labeled surface literal and appearing the embossing pattern of regenerating like that in the space in one's mind.Further, owing to (d) being graphical information and being reproduced as the real object image of three-dimensional image.
The optical wavelength of the tone that is presented because of the light wavelength of the regeneration image of its renewable transparent holographic figure and the outward appearance look of retroreflecting layer with the counterfeit-proof binding mark of this Production Example preparation is almost identical, so can obtain high-definition regeneration picture.
Yet no matter use which type of angle and direction incident white light, can not bear again and only use the reproducible regeneration image of laser.Therefore, if do not know in transparent holographic figure, to exist the hologram image of available laser regeneration, yet how not confirm the means of its existence.Also have, because this white light is not a straight line light, the tone of retroreflecting layer also presents the outward appearance look of interfering material and does not present interference color.
Yet when shining with red laser, the regeneration image of being regenerated by white light has disappeared.This is because the transparent holographic sheet is to select the light of certain wavelengths in the white light regeneration image of regenerating, and the wavelength amplitude that exists in its irradiates light of laser is very narrow, and the regeneration that does not contain regeneration transparent holographic picture is as necessary wavelength.Further change the direction of illumination and the irradiating angle of laser, transparent holographic figure just can clearly observe the new regeneration image that does not observe as the effect of Fourier Tranform hologram under white light.
Fig. 8 shows the skeleton diagram with laser regeneration transparent holographic sheet.
Shown in Fig. 8 (a), cover mark 100 with cylindric thing 104, put a red laser light source 106 in the set red laser entrance port of the part of cylindric thing 104.On the top of cylindric thing 104, embed the ground glass 108 of the effect of playing screen, when the red laser that comes out from red laser light source 106 shines on the mark 100, on ground glass 108, just appear the regeneration picture shown in Fig. 8 (b) in one's mind by the regeneration of transparent holographic sheet.
Stop the irradiation of red laser,, still do not know to exist such hologram image by the just disappearance of regeneration image of laser regeneration.
When further using on the linear light radiation mark 100, the tone of mark is red～purple tone from green～blue tonal variation.
Even, what use in the present embodiment and this Production Example is the hologram interference fringe that is recorded in reproducible hologram interference fringe under the white light and regenerates under laser in a transparent holographic figure, but the present invention does not limit therewith, prepare under white light reproducible hologram respectively and the hologram of under laser, regenerating again their lamination form also passable.Furtherly, as having among Fig. 7,, with the hologram sheet of laser regeneration, also be fine on the further again lamination the hologram sheet lamination of the regeneration picture of 4 pieces regenerate separately (a)～(d).Here, the occasion of so a plurality of hologram laminations must be noted that the hologram image of regenerating is not washed out in mark.
Also have, in the occasion of so a plurality of hologram laminations, each hologram can have reflection horizon alone, and the reflection horizon that perhaps only is provided as the reflection horizon effect in all holograms in the orlop hologram is also passable.But each hologram here have reflection horizon alone occasion its must be the transparent holographic figure that uses metal oxide in the reflection horizon.Production Example 2
Only write down recording materials by the interference fringe of the Fourier Tranform hologram of the renewable regeneration image of laser as the benchmark hologram with the recording materials of the interference fringe of 4 color fringe holograms that write down 1 hologram image separately of being put down in writing by the reproducible Fig. 7 (a) and (b) of white light, (c), (d) and 1, made and amount to 5 pieces and write down the hologram sheet that bears again with the same interference fringe of benchmark hologram with the same regeneration image of benchmark hologram.
This film by the not overlapping lamination that carries out like that of regeneration direction of light, the irradiating angle of renewable image, orlop by the film of lamination on titania on the evaporation, made the transparent holographic sheet.
