Safety element also can duplicate other many information, for example, image graphics, such as portrait 14, or the sign or the coding that constitute, such as bar code or alphanumeric strings.In order to increase the forgery safety of banknote, the information 18 in safety element 16 is general relevant or complementary with an information of the another location that is present in banknote 10 equally, thereby the user can obtain simple authenticity verification.

Referring now to the constructed profile of Fig. 2 structure of the safety element 16 in the key drawing 1 in more detail, Fig. 2 represents the sectional view cut open along the profile line II-II of banknote 10.

At first, stamp color background layer 22 with serigraphy on the whole surface of bank-note paper 20.In the exemplary embodiment, background layer 22 is printed on uniform color tone, and is for example, red, blue or green.Desirable, background layer 22 also is printed with the printing ink of metal effect, for example, and the color of bronze, silver, copper or gold.Other known printing process of those of ordinary skill in the art also can be used for the application of background layer 22, such as offset printing or indirect printing (indirect printing).

Then, on background layer 22, stamp dark China ink, for example, tusche, intaglio layer 24.Except the fine structure that describes below, intaglio layer 24 comprises gap 26, and its shape forms the information 18 among Fig. 1, is numeral " 1 " in the exemplary embodiment.As shown in Figure 2, by intaglio, safety element 16 is presented in the non-interstitial area 28 of intaglio layer 24, and it is the tangible embossment structure of sense of touch with heavy China ink.

In this article, the surface area that is covered by intaglio layer 24 is less times greater than the surface area that is covered by background layer 22.Like this, dark intaglio China ink covers any alignment change of background printing, thereby the observer is formed the impression of good alignment.

Apply the optically-variable layer 30 of printing opacity on many layers of being made up of background layer 22 and intaglio layer 24, for example printed layers has cholesteric liquid-crystal pigments.Liquid crystal layer 30 Show Color transform effects, the color impression in its middle level changes to the observer, for example, from indigo plant to green.

The surface area that is covered by liquid crystal layer 30 is successively less times greater than the surface area that is covered by intaglio layer 24, thereby dark intaglio layer 24 outside of the colour switching effect of liquid crystal layer 30 on bright bank-note paper almost be cannot see.On the contrary, in non-gap area 28 dark, intaglio layer 24, the colour switching effect is very outstanding.In gap 26, the color impression of control background layer 22.Generally, by the color of selection background and the design of intaglio, safety element can provide attracting visual impression to the observer, in addition, by tangible embossment structure of sense of touch and optically-variable liquid crystal layer, has high safety value.

The different distortion of the design of (a)-(e) expression background layer 22 among Fig. 3.In this article, Fig. 3 (a) at first represents whole surperficial background layer 22, as the safety element 16 that also has in Fig. 1 and 2.Background layer 22 in Fig. 3 (b) has the gap 32 of an information shape, is numeral " 1 " here.Should be appreciated that, can combine with the information on the intaglio layer 24 in this information on the background layer 22.

Except simple gap, background layer 22 also can have layout area 34, and its shape forms an information, shown in Fig. 3 (d).Fig. 3 (e) represents another distortion, and wherein background layer 22 has the layout area 34 that comprises the information gap 32 and comprise information.Gap 32 and layout area 34 also can compensate mutually, to form a complete information, for example, shown in the separation numeral " 1 " among Fig. 3 (c).

Fig. 4 represents the design variations of intaglio layer 24.Fig. 4 (a) expression intaglio layer 24 whole surface have the fine structure of being made up of high resolving power line pattern 42,44.The first type surface of intaglio layer 24 is provided with first line pattern 42, wherein parallel lines and horizontal reference direction formation-45.In subregion 46, its shape forms an information, all is numeral " 1 " here in each example, the parallel lines of second line pattern 44 and reference direction formation+45.

Comprise the subregion 46 of information and each oval scope of intaglio layer 24 and centered on by positive boundary contour 48, that is, dark side boundary line around in printed images, can seeing, it is expression more accurately in the detailed Figure 50 shown in Fig. 4 (b).In the exemplary embodiment, the parallel lines of

line pattern

42,44 have the live width b of 100 μ m and the line interval a of 120 μ m.In this article, line at interval a is defined as interval between the same edge of adjacent lines, for example between the coboundary.As following explanation, also can use line at interval a make adjacent lines overlapping less than live width.In the exemplary embodiment, the carving depth of line is approximately 50 μ m.

Fig. 4 (c) represents another distortion of intaglio layer 24, does not resemble the embodiment of Fig. 4 (a), and the subregion 46 that wherein comprises information is provided with negative boundary contour 52.As can be seen, negative boundary contour 52 is the gaps around subregion 46, and can see in printing figure in detailed shearing Figure 54 of Fig. 4 (d).Negative edge outline line 52 among positive boundary outline line 48 among Fig. 4 (a) and Fig. 4 (c) causes the easier observer of allowing of this information to see.

Also have the gap 56 that comprises information in the intaglio layer 24 of Fig. 4 (c), it is corresponding to gap shown in Figure 2 26.For example, according to the distortion of one of Fig. 3, has the unobstructed view of color background layer 22 by gap 56.

Randomly, the intaglio element may further be set in gap 56.Be preferably and adopt the plane, the intaglio China ink is translucent.For example, in gap 56, can be intaglio element (not shown) in conjunction with numeral " 1 " shape.

In the distortion of Fig. 4 (e), oval-shaped intaglio layer 24 is centered on by surrounding edge boundary region 58 in addition, and it is printed with the highlight color covering surfaces.For example, the line pattern 60 of borderline region 58 has the angle direction of subregion 46, and is printed with the live width b of 100 μ m and the line interval a of 90 μ m.Advantageously, background layer 22 and intaglio layer 24 are aimed at mutually, and the border of background layer 22 is covered by surrounding edge boundary region 58.Possible alignment change between background layer 22 and intaglio layer 24 is hidden by borderline region the observer.

The distortion of Fig. 4 (f) is similar to the deformation design of Fig. 4 (e), and just the line pattern 60 of surrounding edge boundary region 58 has with first type surface and comprises

line pattern

42 and 44 different angle directions in the subregion 46 of information.In the exemplary embodiment, for example, the angle direction of borderline region 58 center lines is 0 °.Shown in Fig. 4 (a), subregion 46 is provided with positive boundary contour.

Another distortion of Fig. 4 (g) only is different from the distortion of Fig. 4 (e) by the wide especially information of negative boundary contour 52, it gives lay special stress on to the subregion 46 that comprises information.

Should be appreciated that, every kind of distortion of the intaglio layer among Fig. 4 can with the distortion combination of each background layer 22 among Fig. 3.

(a)-(c) expression is by the sectional view of the intaglio layer 24 of different live width b and line interval a ratio among Fig. 5.In this article, the intaglio layer needn't adopt consistent ratio at whole surface area, but each embodiment of Fig. 5 (a)-(c) can appear at the different subregions of intaglio layer.

In the embodiment of Fig. 5 (a), a is just less times greater than live width b at interval for line, and for example, live width is 100 μ m, and line is 110 μ m at interval.Like this, intaglio printing inks is applied on the whole surface, still, and the thickness of concrete quite big variation.Thereby it is out of question to visually see line, and still, it is very dark that whole surface appears to.The colour switching effect of liquid crystal layer 30 is very outstanding in the zone of this intaglio layer.

At the embodiment at interval of wide line shown in Fig. 5 (b), for example, line is spaced apart 160 μ m, and live width is 130 μ m.In the interval 62 that does not have printing-ink, can see the background layer 22 or the banknote substrate 20 that in Fig. 5 (b), do not have expression.Thereby single line even clearer to human eye, the overall impression on surface is brighter.Like this, the effect of liquid crystal layer 30 is more weak than the embodiment of Fig. 5 (a).

At last, the zone of single line overlap in Fig. 5 (c) expression intaglio layer 24, that is, line interval a is less than live width b.For example, live width b is 130 μ m, and line a at interval can only have 110 μ m.In this article, live width depends on non-overlapped line 64 (in Fig. 5 (c) shown in the dotted line).By this overlapping, realize the surface coverage of very high peace.This embodiment of intaglio layer is particularly suitable for the surrounding edge boundary region, and such as the borderline region among Fig. 4 58, wherein the main border of background layer 22 will be hidden.

(a) among Fig. 6 and (b) expression two more complicated exemplary embodiments of the present invention, wherein in exploded view clearly the diagram be arranged on another layer top the layer.Safety element 70 among Fig. 6 (a) has whole surface color background layer 72, on whole surface color background layer 72 intaglio layer 74 is set.Intaglio layer 74 comprises the fine structure of being made up of the parallel lines of different angles direction, and what the parallel lines of these different angles directions formed numeric string " 10 " shape comprises information subregion 76.Each subregion 76 is surrounded by negative boundary contour.

Intaglio layer 74 also comprises lively figure (being the zebra head in this article) shaped aperture 78, and wherein color background layer 72 can be seen.In addition, background layer 72 is also represented by the interval in the parallel lines of intaglio layer 74.

The surrounding edge boundary region 80 of intaglio layer 74 is with high surface coverage printing, makes the observer not see to be positioned at the border of the background layer 72 below the borderline region 80.

Apply liquid crystal layer 82 on background layer 72 and intaglio layer 74, its colour switching effect is especially outstanding in the non-gap of intaglio layer 74 dark areas.On the contrary, in gap 78, the colored impression of background layer 72 is started to control to make and is used.In the outside of intaglio layer 78, liquid crystal layer 82 is located immediately at above the bright bank-note paper, makes the colour switching effect of the liquid crystal pigment in fact can't see there.

Another exemplary embodiment of Fig. 6 (b) expression security element according the invention 90, wherein color background layer 92 is printed on the shape of an information, is the shape of zebra head in this article.Intaglio layer 94 comprises an information in addition in its fine structure, that is, and and numeric string " 10 ".On two-layer, apply whole surperficial liquid crystal layer 96 again.

Because notch board printed layers 94 is very close to each other in this exemplary embodiment, the optics impression is darker than the situation of the intaglio layer 74 in the exemplary embodiment of Fig. 6 (a).Yet, can clearly see color and the design of zebra 92 by the interval between the parallel lines of intaglio layer 94.
