This purpose is realized by subject matter of the independent claims.Some preferred realities are defined in the dependent claims Apply mode.

The first aspect of the present invention is related to a kind of layer structure for being used for Security element (especially valuable document) comprising uses In the multiple distributed reflection mirrors region for being connected to valuable document substrate, wherein

The multiple distributed reflection mirror region is configured to covering performance figure, wherein

Distributed reflection mirror region is formed by reflecting region, and the reflecting region is applied to multiple relief elements Relief configuration on, and the 10% to 90% or described distributed anti-of the surface of reflecting region covering relief configuration It penetrates mirror region to be formed by high refractiveness reflecting layer, the high refractiveness reflecting layer is applied to the relief structure with multiple relief elements It makes, wherein

When being observed in incident light with the first visual angle, incident light is reflected in distributed reflection Jing Quyuchu, is thus inhibited The distinguishability of the performance figure, and

When being observed in incident light with the second visual angle, which is recognizable.

Reflecting region preferably covers the 25% to 75% of the surface of relief configuration.Reflecting region further preferably covers relief The 30% to 50% of the surface of construction.Reflecting region preferably covers the 50% of the surface of relief configuration.Reflecting region is preferably not Transparent reflection region.

In particular, distributed reflection mirror region is formed by the combination of reflecting region and relief configuration.

In particular, (under the visual angle, incident light is distributed anti-when observing layer structure in incident light with the first visual angle Jing Quyuchu is penetrated to be reflected, thus the distinguishability for showing figure is suppressed), due to the reflection of distributed reflection Jing Quyuchu, Observer is it can be seen that plane gloss.The gloss of light and/or reflection strongly so that observer can hardly or can not Applied performance figure is observed again.

In particular, the performance figure is shown by reflector area when observing layer structure in incident light with the second visual angle Out, therefore the performance figure is visible observer.

It is particularly preferred that the reflection of reflector area can be prevented when observing layer structure in incident light with the second visual angle It is interfered caused by observation performance figure.

The performance figure is preferably applied within/over layer structure.It is particularly preferred that the performance figure constitution layer knot A part of structure.Alternatively, the performance figure is applied in the main region of valuable document substrate, and the layer structure is covered Cover the performance figure.Valuable document substrate includes the first main region and the second main region being arranged opposite to each other, and to observation Person reproduces the information such as denomination, watermark.

Term " the performance figure in the main region of valuable document substrate " should specifically be interpreted as referring to be applied using printing technology Performance figure onto the main region of valuable document substrate.In particular, term " the performance figure in the main region of valuable document substrate Shape " can be regarded as referring to be applied among main region and/or on performance figure.According to a kind of embodiment, this may include The substance (such as printing ink) for being used to form the performance figure penetrates at least partially into valuable document substrate.According to one Kind of alternate embodiments, the substance for being used to form performance figure do not penetrate into instead of in valuable document substrate, only at least one A primary area field surface contact.

" multiple distributed mirror areas of the covering performance figure in main region, wherein the performance figure is according to view for term Angle is hidden by distributed mirror area " be interpreted as refering in particular to the performance graphical layout one of main region of valuable document substrate with Between layer elements or multiple distributed reflection mirrors region.In other words, multiple distributed reflection mirrors region edge above performance figure Thickness direction arrangement.

The layer structure further preferably includes supporting substrate.Distributed reflection mirror region is preferably placed on supporting substrate Face/top.Performance figure is preferably placed between supporting substrate and distributed reflection mirror region.Alternatively, supporting substrate cloth It sets between performance figure and distributed reflection mirror region.Further alternatively, distributed reflection mirror region is arranged in carrying Between substrate and performance figure.

At layer structure/upper the advantages of providing performance figure is, even if on valuable document substrate using swinging technique or In the case where combining swinging technique in valuable document substrate, distributed reflection Jing Qu can be also realized in a manner of precisely aligning The combination in domain and performance figure.Especially when layer structure is designed to anti-counterfeiting line/anti-counterfeiting code, it is particularly the case.

Supporting substrate is preferably transparent.Supporting substrate is preferably thin sheet element or flake.For example, supporting substrate includes Polyethylene terephthalate (PET) and/or polypropylene (PP).

Layer structure is preferably firmly connected to valuable document substrate.

In another embodiment, removal carrying base before or after layer structure is applied to valuable document substrate Material.In this case, performance figure is not to be securely connected to supporting substrate.

Each relief element preferably has the direction limited by inclination angle and azimuth.In other words, relief element direction by Its inclination angle and its azimuth determine.

Each relief element preferably has the inclination angle within the scope of 0 ° to 60 °.

In particular, relief configuration preferably crosses over plane.Relief layer particularly preferably includes the relief configuration across plane.Relief The inclination angle of element corresponds to the angle between the surface normal of plane and the surface normal of relief element.Azimuth determines relief structure Make the direction of the surface normal in crossed over plane.

Preferably, some relief elements have average direction corresponding with predetermined inclination and predetermined party parallactic angle.It is further excellent The deviation of selection of land, other relief elements and predetermined inclination is between 0 ° to 15 °.Alternatively, or in addition, other relief elements And the deviation of predetermined party parallactic angle is between 0 ° to 15 °.

In particular, the deviation relative to inclination angle can be regarded as the inclination angle of the relief element with average direction with other Difference between the inclination angle of the relief element at inclination angle.

In addition, can be regarded as the azimuth of the relief element with average direction relative to azimuthal deviation and there is it Difference between the azimuth of its azimuthal relief element.

For example, the inclination angle of the surface normal of the relief element of average direction can be 35 °.It is average inclined towards (35 °) with this Poor 3 ° of relief element can have 32 ° or 38 ° of surface normal angles.

For example, the azimuth of the surface normal of the relief element of average direction can be 0 °.And azimuth (0 °) deviation 3 ° of relief element can have 3 ° or 357 ° of azimuths.

For example, having the relief element of average direction to can have 15 ° of inclination angles and 40 ° of azimuths.Then with the direction that is averaged (15°；40 °) 3 ° of deviation of relief element can for example have 12 ° or 18 ° of inclination angles or 37 ° or 43 ° of azimuths.

Advantageously, can prevent observer from perceiving destructive diffraction by being changed near average direction Effect.

It should further be appreciated that being capable of increasing the distinguishability for inhibiting performance figure by being changed near average direction Visual angle.Therefore, even if observer still cannot perceive performance figure when viewing angle changes the several years.

Preferably, several relief elements for having the first average direction or deviateing the first average direction form first group. It is further preferred that forming second group with the second average direction or the multiple relief elements for deviateing the second average direction.It is excellent Selection of land, first group of average direction and second group of average difference toward each other.

Preferably, first group of average direction and second group of average direction differ at least 5 °, particularly preferably differ at least 10°.It is particularly preferred that first group of inclination angle and second group of inclination angle differ at least 5 °, particularly preferably at least 10 ° of difference.Especially Preferably, first group of azimuth and second group of azimuth differ at least 5 °, particularly preferably at least 10 ° of difference.

Advantageously, the visual angle of two groups is different.Therefore, by a part of the performance figure of first group of covering in specific view Observer is shown under angle, and by another part of the performance figure of second group of covering for seeing under the certain viewing angles The person of examining is hiding.

Therefore, by the region of the performance figure of multiple groups distribution reflector area covering or performance figure at different visual angles It is lower to be suppressed or show.It therefore, can by mobile valuable document substrate (such as inclination and/or rotation valuable document substrate) Continuously see (difference) part of performance figure.

Second group of reflector area can inhibit entirely to show figure by reflecting or show some region of figure Distinguishability.

When the first area of performance figure is covered by first group (reflector area) and shows the second area of figure When by second group of covering, in incident light:

Under the first visual angle, first area cannot be distinguished by first group, but can distinguish second area,

Under the second visual angle, the first and second regions of performance figure can be distinguished, and

Under third visual angle, second area cannot be distinguished by second group, but can distinguish first area.

When entirely performance figure is covered by first group (reflector area) and shows some region of figure by second When group covering, in incident light:

Under the first visual angle, entire performance figure cannot be distinguished by first group,

Under the second visual angle, entire performance figure can be distinguished, and

Under third visual angle, the region of performance figure cannot be distinguished by second group.

The performance graphics field can be regarded as independent performance figure, and especially they independently can be perceived and be inhibited. Here, the feature and effect of performance figure are also similarly applicable for performance graphics field.The effect of second group of reflector area Similar to first group of effect, especially only visual angle is different, and optional only by the related performance of second group of covering Visuals is different.Other performance graphics fields can be organized respectively by independent (second) and cover, and can be pressed down according to visual angle Make its distinguishability.

Reflector area in first group of relief element inhibits the distinguishability of performance figure.In second group of relief element Reflector area generates can observed person's additional elements for perceiving in performance figure.Second group of reflector area is for observation (metal, preferably silver color) glossy surface is rendered as person.It is additional perceive element especially can independently of performance figure and/ Or it is adapted to performance figure.For example, including such as (individually/main) item of information (such as number, letter, table in performance figure Or pattern) and when background, second group can cover at least part of background and/or provide additional information.For example, second group can be with It forms the outer edge of performance figure or forms the boundary of information, each outer edge or boundary have constant border width or variation Border width.

(do not inhibit entirely to show to make second group of reflector area be rendered as (metal) lustrous regions for observer The distinguishability of figure), it can be envisaged that various methods.Preferably, second group of reflector area and first group of reflecting mirror area Domain, which is compared, has lower relief configuration covering ratio and/or the lesser gross area.For second group, the rate value (or The gross area) to when young half (p2≤p1/2), preferably at least small one third (p2≤p1/3), particularly preferably at least Small by 1/5th (p2≤p1/5).Second group of region is preferably made of fine plane component, such as line and/or point.It is flat Width of the face element part on the direction of its minimum extension size is preferably smaller than 300 microns, particularly preferably less than 100 microns.It can replace Generation ground or additionally, second group of reflector area it is reflexive can reflector area than first group it is low (translucent, relatively thick Rough, different materials).

Using second group of (rather than " inhibition ") of complementarity, following characteristic can be obtained.In incident light, performance Figure is unidentifiable under the first visual angle.The reflection suppression of reflector area in first group of relief element entirely shows figure The distinguishability of shape.In incident light, (entire) performance figure is recognizable at least under the second visual angle.In incident light, The a part for the performance figure not covered by second group of reflector area is recognizable under third visual angle.When with third When view, second group of (non-inhibity) reflector area generate can observed person's perception additional elements.

Under third visual angle, second group of preferred addition shows figure, wherein when mobile around given axis, the second/the Three visual angles are between first and third or the first and second visual angles.When changing visual angle along predetermined direction, such as by surrounding Predetermined axial line tilts or rotates movement come when changing visual angle, performance figure is continuously in a manner of inhibiting, can perceive and supplement Become recognizable form and/or becomes inhibition, recognizable form in a complementary manner and become recognizable form.

The further explanation is generally all suitable for, and is therefore particularly suitable for all groups, or independently of second be optionally present Group is applicable in.

Advantageously, above-mentioned layer structure allows to apply reflecting region to relief configuration, and for alignment precision and/or tolerance There is no very high requirement.In particular, not needing that reflecting layer is just applied to relief structure over the ground using well-designed coating method It makes.Furthermore it is advantageous that relief configuration can accurately be manufactured, so that it is guaranteed that there is only micro- with predetermined relief form Little deviation.In this way, visual angle and/or angular field of view can highly precisely be determined.In contrast to this, in adhesive can The pigment of magnetic alignment can hardly be accurately aimed at/orient.In particular, unexpected direction variation can not occur for this pigment. In addition, also there is this pigment biggish size to be distributed.Finally, as a consequence it is hardly possible to influence distribution of the pigment in adhesive.

This generates particular advantage, the Security element for being easy and fast to, manufacturing to economical and efficient can be provided, and should Security element also provides good optical effect simultaneously.

It is further favourable that in principle, which can be applied in any relief element.In contrast, it is Realize conventional thin slice effect, it is necessary to which reflecting layer is only applied in particular sheet (that is, side of relief configuration).Normal In the flake structure of rule, in the relief configuration with saw-toothed profile, a side of sawtooth must keep areflexia layer, and Another side must be coated with reflecting layer.Therefore, it is necessary to highly precisely coating side face, it is difficult that this will lead to very big manufacture Degree.

Furthermore it is advantageous that reflecting region must only hide the small percentage (i.e. less than 90%) on the surface of relief configuration, So that remaining to inhibit the distinguishability of performance figure in observation appropriate.This observation situation is substantially being divided in light The case where when reflecting and be incident in the eyes of observer at cloth reflector area.In this case, in distributed reflection The brightness of the light of Jing Quyuchu reflection is more than the brightness for the light for reflecting and being incident in observer's eyes at performance figure.Cause This, it is advantageous to the effect is independent of the completely obscured of image.

It is further favourable that the layer structure be made to it is very thin so that layer structure is suitable for anti-counterfeiting line, anti- Pseudo- item and so-called T-LEAD (transfer sheet) or L-LEAD (laminate).

It is further favourable that layer structure can be used in combination with other anti-counterfeiting characteristics, such as hologram, micro mirror array (example Such asMicro mirror array in anti-counterfeiting line), curvature effect, sub-wavelength structure, gamut effect, fluorescent characteristics, with And/or person's electric or magnetic anti-counterfeiting characteristic.For example, above-mentioned layer structure and hologram can also be arranged in anti-counterfeiting line or anti-counterfeiting code.

This combination can exist adjacent to each other, that is, on anti-counterfeiting line or anti-counterfeiting code, layer structure of the invention is present in In first area, and hologram or sub-wavelength structure etc. are present in another region.

It is favorable, however, that the anti-counterfeiting characteristic above referred in second from the bottom section can also be directly integrated into according to this In the layer structure of invention.In particular, reflector area can be formed by the color shifting interference coating (" gamut ") as reflecting region.This It outside, can be to the reflecting region or direct application/offer minor structure, such as holography on it of relief element or reflector area Graph structure or sub-wavelength structure.This sub-wavelength structure as minor structure also can produce color (structural color) or be especially Color change.Particularly advantageously, this sub-wavelength structure can be provided at least some distributed reflection mirrors region, so that working as When being observed in incident light with the first visual angle, incident light is not only reflected at distributed reflection mirror region, but also reflected light There is particular color simultaneously.In other words, sub-wavelength structure influences the color of reflected light.The color of reflected light is also possible to regionality Ground is different, such as the different sub-wavelength structures of penetrating region property, this can generate different colors.Therefore, observer can not only feel Know uniform mono-color reflective.Sub-wavelength structure can be distributed in different reflector areas, allow a viewer to perceive a variety of Color.Alternatively, or in addition, minor structure (such as sub-wavelength structure or hologram) can be distributed in different reflector areas On, allow observer to distinguish additional information (such as text, symbol or denomination).

Another aspect of the present invention is related to a kind of valuable document, has

Valuable document substrate has the first and second main regions being arranged opposite to each other,

Performance figure in one of main region of valuable document substrate, and

The layer structure as described in above-mentioned one or more embodiments, wherein this layer of structure is applied to valuable document base In first main region of material.

The valuable document is preferably banknote.The valuable document substrate includes paper substrates, such as synthesis and/or natural Polymer, especially such as polymer fiber.Hybrid substrate (such as being made of paper and plastic layer) can also be used for valuable document base Material.In particular, the valuable document can have valuable document substrate, such as single-layer or multi-layer paper layer, in the valuable document substrate Among/on application/combination layer structure of the invention, then apply one or more plastic layers.

In particular, being also similarly applicable for the valuable text about the explanation of first aspect and its preferred embodiment Part.

According to a kind of embodiment, the layer structure is also applied in the first main region of valuable document substrate.According to another A kind of embodiment, the layer structure are applied in the second main region of valuable document substrate.

It is related to a kind of method for manufacturing valuable document on the other hand comprising following steps:
