Abstract
A multilayer body is disclosed, comprising two laser-sensitive layers (4, 32). Said multilayer body is a laminated body of overlay films (30, 32), inlays (90, 90) and further overlay films (30,30). The upper overlay film (30) comprises a layer structure applied to the underside thereof by application of a hot-stamp film. The layer structure comprises a lacquer layer (50), a reflection layer (5r), a laser-sensitive layer (4), a background layer (5) and an adhesive layer (6). A diffraction and/or hologram structure (5b) is embodied in the lacquer layer (5c), the reflection layer (5r) and the laser-sensitive layer (4). The second laser-sensitive layer is embodied as a carbon-doped overlay film (32). A laser-induced, preferably coloured image component can be generated in the upper laser-sensitive layer (4) and a further, preferably grey-scale image generated in the carbon-doped laser-sensitive layer (32) thereunder by means of laser treatment. A laser-induced multilayer image can thus be produced.

The specific embodiment
Heat pressure film shown in Fig. 1 is a kind of polylayer forest with two laser-sensitive layer 4, and laser-sensitive layer is formed on 5r both sides, reflecting layer.In laser-sensitive layer, can insert different laser induced marks by laser treatment, thereby produce the laser induced multi-layer image of a combination this polylayer forest.Correspondingly at the laminated film shown in Fig. 2 too, it is equivalent to divert film among Fig. 1 in its layer configuration aspects.Correspondingly at the heat pressure film shown in Fig. 3 too, it has different layer structures, but two laser- sensitive layer 4,4a are arranged equally.Layered product shown in Fig. 4 also has two laser-sensitive layer, that is layer 4, and they are arranged on overlapping film 30 bottom surfaces one and are attached in the heat pressure film there; With layer 32, it constitutes the overlapping film of independent interpolation.
Describe the structure of single polylayer forest in detail below in conjunction with accompanying drawing, and laser treatment, the laser induced image part of making full-colour image can be produced with it.Next introduces a kind of method that how to produce as the grayscale image of laser induced image part in another laser-sensitive layer.
Each layer is disposed in order with following in the film in Fig. 1:
Fig. 2 represents that one has the embodiment corresponding to the layer laminated film in proper order of heat pressure film structure.It comprises that a so-called overlapping film 30, a laser-sensitive layer 40, constitute the intermediate layer 50 (it is optional) and a bond layer 60 of background layer, and it is optional equally.Laser-sensitive layer 40 to be to be arranged on 50r both sides, reflecting layer as laser-sensitive layer 4 corresponding modes, wherein with Fig. 1 in corresponding mode, two laser-sensitive layer are made similar and different.With a same diffraction and/or the hologram structure 50b of in the laminated film of Fig. 2, also correspondingly being provided with of heat pressure film among Fig. 1, and same in the zone of two laser-sensitive layer 40 and the reflecting layer 50r between them.
Produce laser induced image part when the heat pressure film among Fig. 1 or the laminated film among Fig. 2 are carried out laser treatment in overlapped laser-sensitive layer respectively, they are positioned at different layers.Laser treatment is preferably in carries out after relevant film is attached on the matrix, that is uses the method that is attached to the film on the matrix from external irradiation to carry out.But also can before pasting, handle membrane laser as another kind of the selection.The laser irradiation is then carried out from the film both sides in this case.
Obtain different laser induced image part in overlapped laser-sensitive layer by such method, be that laser-sensitive layer has different laser-sensitive materials, thereby under different lasing conditions, can in different laser-sensitive layer, produce laser induced image part by the material decision.But select also can only handle above or below laser-sensitive layer by changing incidence angle as another kind.This possibility obtains by such method, and promptly reflecting layer 5r can pass through when the vertical incidence for laser emission, but with acute angle incident the time can not or less passing through.Transmission for diffraction structure is also distinct, that is to say by the incidence angle of correspondingly adjusting laser emission and can handle individually top laser-sensitive layer, so that produce a specific laser induced image part there, and ray does not arrive following laser-sensitive layer.Therefore also can handle overlapped laser-sensitive layer individually in this way, if they are made by identical laser-sensitive material certainly.
Be provided with two laser- sensitive layer 4,4a among the embodiment of the heat pressure film in Fig. 3 equally.But they are spaced from each other by a background layer 5 that is arranged between them.Background layer is a layer for the high degree reflection of laser emission used when the laser treatment.This layer is not penetrating for the not reflecting part of laser emission and absorbs in addition, therefore do not have laser emission arrival and be positioned at laser-sensitive layer 4a below it when being used for producing the laser treatment of the laser induced mark superincumbent laser-sensitive layer 4 in.Background layer 5 only is arranged on below laser-sensitive layer 4 in such zone, should produce laser induced image part in this zone in laser-sensitive layer 4.Outside this zone, do not form background layer 5, that is the transparent material of laser emission is set in this zone, or the laser-sensitive material of the laser-sensitive layer 4a especially.Produce laser induced image part in the laser-sensitive layer 4a below in not forming the zone of background layer, can being radiated at by laser.
Two laser- sensitive layer 4,4a preferably are made up of different laser-sensitive materials, are suitable for adopting the different laser treatment conditions that determined by material for them.Can interior the generation between laser induced mark phase of laser-sensitive layer 4a below can not produce laser induced variation in the simultaneously superincumbent laser-sensitive layer 4 in this way.
In order to prevent that laser from injecting in the matrix, the bottom surface of laser-sensitive layer 4a below is provided with another background layer 5a.This background layer 5a prevents that laser emission arrives matrix when laser treatment.
Embodiment among Fig. 4 involves a kind of layered product of being made up of different overlapping films and embeding layer.Go up overlapping film and on its bottom surface, have the layer structure of forming by an enamelled coating 5c, reflecting layer 5r, laser-sensitive layer 4, background layer 5 and bond layer 6.In enamelled coating 5c, reflecting layer 5r and laser-sensitive layer 4, form a diffraction and/or hologram structure 5b.
This layer that is attached on overlapping film 30 bottom surfaces is the heat pressure film layer, and it is attached on the bottom surface of overlapping film there.Be arranged on overlapping film 30 following overlapping films 32 and make the laser-sensitive film.That is to say that it constitutes second laser-sensitive layer.The laser-sensitive material is made the material that adds carbon or carbon black in the embodiment shown.It is a kind of material of carbonization when laser action, make this constitute by overlapping film 32 the layer in the complete blackening of laser induced image part.
Below the overlapping film 32 that adds, establish an embeding layer 90 and another embeding layer 90 below it.These embeding layers especially can still also can especially be made embeding layer-film by plastic material by paper material.Paste an overlapping film 30 on the bottom surface of embeding layer 90 below, and on it, paste another overlapping film 30.
In the present embodiment with carrying out laser treatment, so that in laser- sensitive layer 4 and 32, produce different laser induced image parts with identical method when Fig. 1 to 3.
Specify again below, how in the laser-sensitive layer of forming by the pigment composition that comprises three kinds of laser-sensitive pigment compositions, can produce a full-colour image part by laser induced district.The laser-sensitive material relates to a kind of ternary mixture that has green pigment composition, magenta pigment composition and yellow uitramarine composition.
When bleaching, the method by shining with certain optical maser wavelength that certain pigment composition is bleached at this position produces blue or green or red-label in first work step.
In order to produce blue color, only allow the yellow uitramarine composition to bleach.Adopt blue look laser for this reason.Need certain minimum strength in order to bleach.Secondly do not allow to surpass certain pulse duration.In order in first work step, to obtain Green Marker, only allow the magenta pigment composition to bleach.Adopt green laser for this reason.In order in first work step, to obtain red-label, only allow cyan (Cyan) pigment composition to bleach.Adopt red laser for this reason.
In order to produce cyan or magenta or yellow color mark at this position, the optical maser wavelength that is used for making the pigment composition that also do not bleach at this position to bleach in second work step at this position is carried out laser treatment.If in first work step, produced blue color marker, do not bleach at this position green pigment composition and magenta pigment composition so.In order to produce cyan at this position, the magenta pigment composition must bleach in this second work step.This carries out with green laser.Therefore obtain the cyan mark at this position.
If be not to obtain the cyan mark in second work step, but should obtain the magenta mark, the blue color marker that obtains in first work step must be handled with red laser so.Green pigment bleaches on this position thus, makes just that magenta color remains unchanged white on this position.Thereby obtain the magenta mark at this position.
With correlation method can by in first work step, produce, by the there Green Marker that white green pigment and viridine green constitute that remains unchanged, by handle generation cyan mark or yellow mark with blue look laser or red laser.
Can be with corresponding method with the red-label that in first work step, produces at the second work step transfer yellowing or magenta mark, and be by in second work step, carrying out laser treatment with green laser or blue look laser.
In order to obtain a transparent position on the position of in first and second work steps, handling, that is obtain a white position (if background layer 5 be white), this position must be handled with such laser emission in the 3rd work step so, its wavelength is adjusted like this, make the pigment composition that behind second work step, bleaches not yet at this position bleach, that is yellow mark must be with blue look laser, and the magenta mark bleaches with red laser with green glow, cyan mark.
Other adjacent regions in the processing laser-sensitive layer 4 that uses the same method then are so that produce other colour-codeds in the layer 4 of embossed film.Can produce full-colour image in this way.
In order in the pigment of laser-sensitive layer or multiple pigment, to produce colour-coded or full-colour image, also can adopt laser treatment by color transition.Laser treatment can be carried out with the work step that connects in turn mutually by corresponding manner.As pigment that is coloring matter, consider to adopt pigment.They scarcely dissolve, and inorganic substances normally.But also can consider the organic pigment of great majority dissolving as pigment.Color transition carries out under specific lasing condition respectively, and they use in each work step when laser treatment.
If correspondingly the laser-sensitive material only is made up of one or both pigment component, so also can adopt described bleaching or the color transition method.Also can adopt other pigment compositions, and when laser treatment, adopt other lasing condition, particularly other laser wavelength range.
Laser treatment is carried out on the film that is attached on the matrix usually; but select also and can before pasting film, carry out by the method for irradiate only as another kind; if protective layer 3 or any other layer particularly; for example background layer 5 is done and is paired in that laser emission does not penetrate or the layer of partial penetration only, or the layer that does not penetrate for the laser emission in certain wave-length coverage.Or the words of a ultraviolet radiation absorption protective layer are set additionally.By with the laser emission alignment thin film back side, that is following background layer 5 or adhesive linkage 6, that is to say from opposite side laser-sensitive layer 4 is handled,, especially before pasting film, carry out laser treatment so that in kind produce the method for colour-coded in its inside.This when being used for relevant laser emission background layer 5 and bond layer 6 be transparent or partially transparent at least.

Also should be illustrated object of the present invention with its major advantage and function again at last in conjunction with Fig. 5 to 7.
Create a kind of multi-layer data carrier, it comprises two different laser-sensitive layer at least, and one of them laser-sensitive layer 1 preferably can produce the Multi Colour Lasers mark, and another laser-sensitive layer 2 especially can produce the one-wavelength laser mark.
The laser-sensitive material can be adjusted in such a way for this reason, makes to produce mark in two kinds of materials by means of the laser emission of certain wavelength and intensity.
Laser-sensitive layer the pick of area is overlapped.
Between these laser-sensitive layer, be provided with the part area one for laser emission do not penetrate the layer 3.This optical barrier layer 3 is reflecting layer, is a diffraction reflection layer in the preferred structure scheme.This preferably comprises the white pigments of enough deals, thereby prevents that laser from invading the layer be positioned at below it.This is the precondition of layout that can produce the layer of laser labelling by difference of the present invention.By the separation of optical barrier layer, the layer 1 that can produce the laser labelling of polychrome can be positioned on the layer 2 that can produce the one-wavelength laser mark, but and does not cause the carbonization that is positioned at the personalized layer 2 of monochrome laser below it when color laser is personalized.
Optical barrier layer can be inserted as extra play with distinct methods.Especially optical barrier layer uses the decorating printing choice specimen of calligraphy on a cover layer.
Described multi-layer data carrier can be made by one of following method:
Injection moulding, especially multi component injection molding or Inmould decorate, the lamination of laminated film,
Especially the lamination of the mixed structure of forming by paper and plastic sheeting,
The coating of paper substrate body or plastic substrate,
The printing of paper substrate body or plastic substrate,
Film transfer process on paper substrate body or plastic substrate, or the combination of described method.
Fig. 1 represents a kind of preferred structure of data medium.
Optical barrier layer also can be arranged on the laser-sensitive layer, thereby causes the part area of laser-sensitive layer to hide.At this moment this optical barrier layer is preferentially made the decorating printing layer, line image especially, as carve little decorative pattern form.But if then after producing laser labelling the image information of decorating printing layer be delivered in the personalized layer of laser, the image information of laser personalization so here is owing to the image information of optical barrier layer is interrupted.
Because display by means of the personalized pictorial element part as file on the meaning of coloured image that produces of color laser, must give false proof reliability.By coloured image being separated from file and can being caused the danger of forgery with the method for other image replacement.If the pictorial element of laser personalization is combined into coloured image with other elements of file on the integrated background meaning of photoelectricity, just good false proof protection is provided so.
Different characteristic integrated: the personalized and gray level laser personalization of color laser is carried out with such form in a data medium, but the personalized layer only overlapped setting of part area of promptly different laser.Obtain the different possibilities of integrated color laser personalization thus.
Fig. 6 represents the possibility of the laser labelling on a kind of priority structure of data medium.
But if on the position of having only the personalized layer 2 of monochrome laser, carry out the laser personalization, just produce monochromatic black mark 9 so.
But if but on the position of having only the layer 1 above the layer 2 that is positioned at not penetrable layer 3 and the personalization of monochrome laser of polychrome laser personalization, carry out the laser personalization for laser emission, just produce multi-color marking 8 so.
But if but on the position that only is positioned at the personalized layer 1 of polychrome laser on the layer 2 of monochrome laser personalization, carry out the laser personalization, and do not separate by optical barrier layer 3, so just, produce the stack of multi-color marking 9 and monochromatic black mark 8, this mark is polychrome equally, but since the contrast effect of break-in and blackout it seem darker than pure multi-color marking.
Fig. 7 represents how to shine the pictorial element that the reachability set that combines becomes by the personalized and traditional gray level laser of color laser.But adjust the absorption of the personalized layer of laser for this reason in this wise, but make and be enough to make carbonization in the personalized layer of the monochrome laser that additionally adopts hereof for the needed laser power that bleaches.But if but the personalized layer 2 of monochrome laser be positioned under the personalized layer 1 of polychrome laser, and it only the part area hide by optical barrier layer 3, so this structure allows to see through optical barrier layer 3 and is excited light-struck pictorial element, and for example straight line or letter character impel the background carbonization.Can within element, produce penetrating pictorial element so with type conversion.If but the border of optical barrier layer 3 is consistent with personalized layer 1 of polychrome laser, just form from colour to achromatic conversion.This penetrating image information plays a part integrated.
Integrated in addition pictorial element can reach in combinations personalized by color laser and other pictorial elements.But the transparency of the personalized layer of polychrome laser strengthens with the increase that bleaches.This permission, the layout element, but for example be printed on the layer that is positioned under the personalized layer of polychrome laser, for example the little decorative pattern of the engraving on the core material displays in coloured image in color laser irradiation back.Thereby only but the part area is by the graphic element of personalized layer 1 covering of polychrome laser, and for example Yin Shua straight line shows as integrated element after the color laser personalization.Being stretched over the integrated element that surpasses personalized marker edge makes the forgery of data medium more difficult to a great extent.
Another feature of the present invention is that extra play allows irrespectively to adjust on request with used matrix material the brightness of background.For example can be by adopting optical brightener or adopting the pigment additive to reach additional effect.
From the above mentioned, of the present invention it comprises at least two different laser-sensitive layer to liking a kind of multi-layer data carrier, but one of them laser-sensitive layer is the personalization of polychrome laser, but another laser-sensitive layer is the personalization of monochrome laser.These laser-sensitive layer segment areas are overlapped, but but especially the personalized layer of polychrome laser be positioned at the top of the personalized layer of monochrome laser.Laser-sensitive layer can be made like this, but but promptly can be in a laser marking work step with the laser emission of identical wavelength and the energy not only corresponding mark of generation in the personalized layer of polychrome laser but also in the personalized layer of monochrome laser.
Be preferably between these laser-sensitive layer and be provided with for the impenetrable layer of laser emission to small part area ground.
The impenetrable layer of laser emission is a reflecting layer especially, and it can be the diffraction reflection layer in preferred structure, and comprises a kind of reflection of enough deals or the auxiliary material of scattering laser light.
But in the personalized layer of the laser that the laser personalization can be on one, but especially in the personalized layer of polychrome laser, carry out, and can not change owing to but laser emission makes the personalized layer of the laser that is positioned at below this layer, can carry out the laser personalization by such method.Promptly do not carry out at the position that separates of the mutual optics of penetrated bed by laser emission in laser-sensitive layer.
By in laser-sensitive layer not by the laser emission position that separates of the mutual optics of the penetrated bed method of carrying out the laser personalization not, but both can be superincumbent the personalized layer of laser, but especially in the personalized layer of polychrome laser, but can carry out the laser personalization with a laser emission by the personalized layer of laser below being positioned at this layer again.
Carry out the laser personalization with such method, be but that graphic pictorial element is arranged on the personalized layer of corresponding laser, but especially on the personalized layer of polychrome laser, make and within pictorial element, reach the conversion that from the polychrome to the monochrome, shows, but by such method with a laser emission both can be superincumbent the personalized layer of laser, but especially in the personalized layer of polychrome laser, but can carry out the laser personalization by the personalized layer of laser below being positioned at this layer again.
But can in the personalized layer of a laser, carry out the laser personalization with a laser emission, wherein the laser personalization is carried out in such a way, be but that graphic pictorial element is arranged on the part area that is located at the optical barrier layer on the personalized layer of laser, but make the interruption that in the personalized layer of laser, reaches the printed image elements of such generation.Element as the interruption on the optical barrier layer meaning especially can be a printing element, but for example is arranged on the little decorative pattern of engraving on the personalized layer of laser.
Can in the personalized layer of a Multi Colour Lasers, carry out the laser personalization with a laser emission, but the feasible layer that is printed on below the personalized layer of polychrome laser, the structural element on the matrix material for example, especially Yin Shua element, for example carve little decorative pattern, display in coloured image in color laser irradiation back, but wherein pass through the transparency that the laser marking process improves the personalized layer of polychrome laser.
Major advantage of the present invention is that the color laser that known gray level laser is personalized and new is individual The property method combines. The security of file can improve greatly by the combination of described method.
