FIELD OF THE INVENTION
The present invention relates to a security document or token, such as a bill or the like, and is particularly, but not exclusively, concerned with providing a security document having an improved security device.
BACKGROUND OF THE INVENTION
Australian Patent AU-A-87 665/82 describes a security document and a method of making a security document in which opaque layers are coated on both sides of a plastic film substrate. The security document is produced in areas where no opaque ink is applied to both sides of the substrate to form "windows" so that a security device can be inserted into these "windows". A disadvantage of the security document of this patent is that the security device on the window can be fraudulently changed.
Australian Patent 199741934 describes the. Application of an opaque layer on one side of a window to form a partially transparent or translucent window or "half-window". In this design, the security device is provided between the opaque layer and the substrate. The security device in the half-window can not be very easily fraudulently changed because the security device is located between the substrate and the opaque layer. A disadvantage of the security document of this patent is that the security device of the window can not be seen or at least is hardly visible in transmitted light when viewed from the other side.

Diffractive optical elements (DOE)
The term "diffractive optical element" as used herein refers to a numerical-type diffractive optical element (DOE). DOE numeric type are based on the
Assignment of complex data that reconstruct a two-dimensional ray image on the distal field (or on the reconstruction plane). Thus, when heavily collimated light rays, for example from a point light source or a laser, fall on the DOE, an interference pattern is formed which forms a projected image on the reconstruction plane which is visible when a suitable viewing surface is in the reconstruction plane or if DOE is considered when the light falls through on the reconstruction plane. The transformation between the two planes can be approximated by means of a fast Fourier transform (FFT). Therefore, complex data, including amplitude and phase information, must be physically encrypted in the DOE's microstructure. These DOE data can be calculated by performing an inverse fast Fourier transform of the desired reconstruction (i.e., the desired beam image in the distal image). DOEs are sometimes referred to as computer-generated holograms, but they differ from other types of holograms, such as rainbow holograms, Fresnel holograms, and volume-reflection holograms.
Optically variable element or image
The terms "optically variable element (OVD)" or "optically variable image" as used herein refer to a security feature whose appearance changes. OVD provide a visually variable effect when the bill is tilted and / or the viewer's viewing angle changes relative to the OVD. The image of an OVD can also be through
Alignment of a tester above the safety feature or safety device. An OVD may be provided by a printed area, for example, a region printed with metallic inks or iridescent inks, by an embossed area, and by a combination of a printed and embossed feature.
An OVD may also be provided by a diffractive device, such as a diffraction grating or a hologram, and includes an array of microlenses and lenticular lenses.
The invention comprises the aforementioned features and also provides constructions which will be referred to below by way of example only.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figure 1, a security document 10 according to one embodiment of the present invention comprises a substrate 12 and opaque layers 14, 16. Further, security document 10 comprises a security element 11. The security document is preferably a banknote. Alternatively, the security document may be a credit card; a check; a passport; an identity card; a security and share certificate; a driver's license; a title deed; a travel document; an entry document; a birth, death or marriage certificate; and be a university certificate.
The substrate 12 is an optically transparent material. The substrate 12 may be formed of a plastic or polymeric material. The substrate may be formed of, for example, polypropylene (PP), polyethylene (PE), polycarbonate (PC), polyvinyl chloride (PVC), polyethylene terephthalate (PET), biaxially oriented polypropylene (BOPP). Alternatively, the substrate 12 may be formed from a substantially opaque material, such as paper or a fibrous material, which has one or more inserts of transparent plastic material, which insert or inserts into a cutout or depression in the paper or paper fibrous material is used. The substrate 12 may also include a composite of two or more materials, such as a laminate of paper and at least one plastic material, or two or more polymeric materials.
The substrate 12 has a first surface and an opposite second surface. The first surface of the substrate 12 may be the front surface of the substrate while the second surface of the substrate 12 may be the rear (or back) surface of the substrate. A first opaque layer 14 is applied to the entire first surface of the substrate 12, except for an optically transmissive region 18b of the substrate 12.
A second opaque layer 16 is applied to the entire second surface of the substrate 12, except for an optically transmissive region 18a of the substrate 12.
As shown in Figure 1, an edge of the uncovered optically transmissive region 18b on the first surface of the substrate lies directly over an edge of the uncovered optically transmissive region 18a on the second surface of the substrate 12. The uncovered region 18a of the first surface does not substantially overlap that uncovered area 18b of the second surface. That is, neither of the two uncovered areas 18a, 18b can be seen through the other uncovered area. When viewed through one of the two uncovered areas 18a, 18b, the opaque layer would become visible on the other side and, if present, one or at least part of a security device.
From the front and rear views of the security document 10 shown in Figures 2 and 3 respectively, it will be seen that the first uncovered area 18a and the second uncovered area 18b appear substantially continuous in transmitted light. In particular, the first uncovered area 18a appears to have a common edge in incident light with, touching or adjacent to the second uncovered area 18b. The uncovered areas appear to be contiguous within a range of predefined viewing angles.
The predefined viewing angle preferably includes a viewing angle that is substantially normal to the first and second surfaces. That is, the predefined viewing angle includes a viewing angle that is generally perpendicular to the first or second surface. The range of predefined viewing angles is preferably between about -60 ° and about + 60 ° to the normal of the first and second surfaces. More preferably, the range of predefined viewing angles is between about -45 ° and about + 45 ° to the normal of the first and second surfaces. More preferably, the range of predefined viewing angles is between about -10 ° and about + 10 ° to the normal of the first and second surfaces.
Figures 1 to 3 show that the first surface and the second surface of the substrate 12 each include an area that is not covered by an opaque layer. According to other embodiments of the invention, the first and / or second surface of the substrate may include more than one area that is not covered by an opaque layer. If the first and / or second surfaces of the substrate comprise more than one uncovered region, the uncovered region (s) of the first surface and the uncovered region (s) of the second intersect Surface not essential. If the first and / or the second surface of the substrate comprise more than one uncovered area, the first area (s) and the second area (s) appear substantially continuous when they are be viewed in transmitted light.
This arrangement results in a first half-window area A having an uncovered area 18a on the second surface of the substrate 12 and a covered area on the first surface of the substrate 12, and a second half-window area B with an uncovered area 18b on a first surface of the substrate 12 and one covered area on the second surface of the substrate 12. The half-window areas A, B are aligned with each other. The first half window area A does not substantially overlap with the second half window area B. Furthermore, there is substantially no space between the first and second half window areas A, B. The half window areas A, B are substantially continuous. The first half-window area A seems to have a common edge with the second uncovered area B, to touch it or to lie next to it.
Parts of a security device that are present in the half-window areas A, B have different levels of visibility depending on the side of the document viewed by the security device.
When the security document 10 is viewed from the rear side (FIG. 3), a security device mounted in or on the substrate in the half-window areas A, B appears more clearly in comparison to the second half-window area B in the first half-window area A. Conversely, a security device mounted in or on the substrate in the half-window areas A, B appears more clearly compared to the first half-window area A in the second half-window area B when the security document 10 is viewed from the front side (FIG. 2). The
Safety device can be detected by the uncovered area 18b on the first surface against the opaque layer 16 on the second surface in the second window area B. The security device may be recognized by the uncovered area 18a on the second surface against the opaque layer 14 on the first surface.
The security document 10 includes a security device 11 in the substrate 12. The security device 11 may additionally or alternatively be mounted on the substrate 12. The security device 11 may be sandwiched between the optically transmissive zone and the opaque layer on the second surface.
The safety device 11 is shown in the form of a security thread. The security device 11 may additionally or alternatively comprise one or more of fluorescent, luminescent and phosphorescent inks, metallic inks, iridescent inks, photochromic, thermochromic, hydrochromic or piezochromic
Inks, printed and embossed features, including relief structures, interference layers, liquid crystal devices, lenses and lenticular structures, and / or optically variable devices (OVD), such as diffractive elements including diffraction gratings, holograms, and diffractive optical elements (DOE) , As shown in Figure 1, the security thread extends the length of the substrate 12. In other embodiments, the security thread or other security device 11 does not extend the length of the security document and is at least only in the uncovered, optically transmissive areas 18a, 18b of the Substrate 12 present.
The security device, which is visible in the first window area A, is preferably of the same type as the security device, which is visible in the second window area B, which is a security thread. In other embodiments, the security device that can be seen in the first window area A may differ from the security device that can be seen in the second window area B.
It is shown that the security device 11 extends to areas of the substrate 12 which are outside the half-window areas A, B, where the first and second surfaces are both covered by an opaque layer 14, 16. Parts 11c of the safety device 11 which extend beyond the half-window areas A, B are more visible in transmitted light than in reflected light. Parts 11c of the safety device 11, which are outside the half-window areas A, B, are in comparison to the
Parts 11a, 11b of the security device 11 in the half-window areas A, B not so visible.
It is illustrated that the security device 11 is embedded in the second surface of the substrate 12. According to other embodiments, the
Safety device in the first surface of the substrate. According to other embodiments, the security device is located in the first and second surfaces of the substrate. According to further other embodiments, the security device is located on the first and / or second surface of the substrate.
As shown in Figure 2, a portion 11b of the security device 11 is viewable from a front view of the security document 10 through the uncovered area 18b of the first surface against the opaque layer 16 on the second surface in the second half-window area B. A part 11a of the security device 11 can be seen in transmitted light in the first half window area A, but not as clearly as the part 11b of the security device 11 in the second half window area B. Parts 11c of the security device 11 lying outside the half window areas A, B can also however, compared to the part 11a of the security device 11 in the first half-window area A less clearly, and even less clearly compared to part 11b of the security device 11 in the second half-window area B.
As shown in Figure 3, a portion 11a of the security device 11 is viewable from a rear view of the security document 10 through the uncovered area 18a of the second surface against the opaque layer 14 on the first surface in the first half-window area A. A part 11b of the security device 11 can be seen in transmitted light in the second half-window area B, but not as clearly as the part 11a of the security device 11 in the first half-window area A.
Parts 11c of the security device 11 which are outside the half-window areas A, B can also be seen in transmitted light, but less clearly compared to the part 11b of the security device 11 in the second half-window area B, and even less clearly compared to part 11a of the security device 11 in the first half-window area A.
The security document 10 is manufactured in such a way that the first half-window area A and the second half-window area B are lined up. That is, the first and second half-window areas appear side by side when the security document 10 is viewed in transmitted light. In particular, an edge of the first half-window area A lies directly below an edge of the second half-window area B, so that the two half-window areas appear to be touching each other in transmitted light.
The manufacturing method of the security document according to an embodiment of the present invention comprises the following steps:
Providing a substrate comprising an optically transmissive region;
Depositing a first opaque layer on a first surface of the substrate, including a portion of the optically transmissive zone, with a portion of the optically transmissive zone not covered by the first opaque layer; and
Applying a second opaque layer on a second surface of the substrate, including a portion of the optically transmissive zone, the second surface on one side of the substrate facing the first surface having a portion of the optically transmissive zone other than the second opaque one Layer is covered.
The uncovered area of the first surface does not substantially overlap the uncovered area of the second surface. The first uncovered area and the second uncovered area appear substantially contiguous when viewed in transmitted light.
Referring to Figs. 4 and 5, if there is a substantial area between the first half window area A 'and the second half window area B' where an opaque layer is deposited on the first and second surfaces of the substrate, then the first half window area A and the second half-window area B 'are said to be non-abutting. In this arrangement, the first half-window area A 'appears spatially separated from the second half-window area B' by an opaque zone C in transmitted light. In the opaque zone C, the first and second surfaces of the substrate 22 are covered with an opaque layer 24, 26. Looking at the front side of the security document in transmitted light, a part 21b is the
Safety device 21 in the second half-window area B 'clearly visible. One part 21a of the second
Safety device 21 is less visible in the first half-window area A '. A portion 21d of the security device 21 is even less visible in the opaque area C and has the same level of visibility as parts 21c of the security device 21 outside the window areas. A viewer of the document 20 with the security device 21 can therefore recognize a forged document since this is due to the presence of part 21d of the
Safety device 21 between the half-window areas A 'and B' does not have an exact alignment between the edges of the half-window areas A 'and B' has.
If there is a substantial overlap between the first half-window region and the second half-window region, as shown in FIGS. 6 and 7, then the first half-window area A "and the second half-window area B" are said not to abut one another. In this arrangement, the first half-window area A "appears spatially separated from the second half-window area B" by an opaque zone C 'in transmitted light. In these figures, an edge of the half-window region A ", B1 'lying on one surface of the substrate 32 falls above or below an uncovered area of the substrate 32 on the other surface to form a full-window area C'. In the full-window area C ', a part 31d of the safety device 31 can be seen without an opaque layer behind it. Looking at the front side of the security document 30 in transmitted light, a part 31b of the
Security device 31 in the second half-window area B1 'clearly visible against an opaque layer. A portion 31a of the second security device 31 is less visible in the first half-window area A ", and parts 31c of the security device 31 outside the half-window areas A" and B "and the full-window area C 'are even less visible.
Therefore, a viewer of the document 30 with the security device 31 can recognize a forged document because it does not have an exact alignment between the edges of the half-window areas A "and B" due to the presence of the full-window area C 'and the part 31d of the security device 31 ,
Preferred embodiments of the invention have been described by way of example only, and modifications may be made thereto without departing from the scope of the invention.
Other variations and embodiments include those described in the "Summary of the Invention" section.
