SECURITY DEVICE AND METHOD OF MAKING SAME

Abstract A method of covering, embedding or burying magnetically encodable regions, invisible to the naked eye at least on one side, in a security device begins by providing a security device carrier substrate having an imaged metallic region. A foil film is provided having a metallic layer on a carrier substrate and release lining. One or more magnetic regions are provided on either the foil film layer or the carrier substrate. Patterned, flat, or roller heated dies are used to bond the foil film to the security device carrier substrate in at least those regions of the magnetic regions thereby producing a security device having covered, embedded or camouflaged magnetically encodable regions.
Full Text FIELD OF THE INVENTION
This invention relates to security and authentication devices
and more particularly, to a method for producing a
security/authentication device having visually camouflaged
magnetically encoded information and to a security device
resultant therefrom.
BACKGROUND
Security devices or threads and other authentication devices
are nearly always used in currency and other important papers,
negotiable instruments or product wrappings. These security
threads provide a visual and/or mechanical (i.e. machine readable)
means of verifying the authenticity of the object to which the
security/authentication device is attached or embedded such as
high-priced items; easily counterfeited items including currency
and other negotiable instruments; tickets to special events; and
even consumer products such as pharmaceuticals, certain clothing,
liquor and the like, all of which are or have been subject to
counterfeiting.
One method of object authentication involves embedding a
machine-readable security feature either alone or in combination
with a visually discernible security feature in the
security/authentication device. The machine readability of at
least that portion of the security/authentication device allows a
machine to verify the authentication of the object to which the
security/authentication device is attached, thereby eliminating
human error in such authentication and also speeding up the
process of authentication.
Machine-readable security features are often generally
provided using one or more magnetic regions which are generally
opaque on a clear plastic substrate and which can be encoded (such
as by magnetizing) in the security/authentication device. As with
security/authentication devices having only a visual
authentication methodology, those with only machine readable
authentication features or machine readable authentication
features in combination with visual authentication features can be
more easily counterfeited if the potential counterfeiter can
detect the presence and/or placement of the magnetically encoded
region to read and reproduce it. If the magnetic or other machine
readable information cannot be visually seen, the counterfeiter
will not generally know to reproduce this information and
therefore the counterfeiting will fail and be easily detected.
SUMMARY OF THE INVENTION
The present invention features a method for camouflaging,
using one or more metalized foil layers, one or more -magnetic
regions on a security device, such as a thread, which can be
embedded in an instrument' requiring authentication such as paper
currency or other negotiable instrument and a resultant security
device.
Accordingly, the present invention provides a security device for use with an item to
provide multiple security features, said security device comprising:
a carrier substrate having a width;
at least one metallic region disposed on at least a portion of said carrier substrate;
at least one metallic foil region disposed on at least a portion of a release coated
carrier film, said metallic foil region having a top and bottom surface; and
at least one magnetic region disposed on at least one of either said carrier substrate or
said release coated carrier film, such that said at least magnetic region is enclosed between
said carrier substrate and said at least one metallic foil region disposed on at least a portion of
said release coated carrier film after said carrier substrate and said release coated carrier film
are contacted under conditions that serve to bond the metallic and magnetic regions together.
According to the present invention, there is also provided a method of making a
security device for use with an item to provide camouflaged multiple security features, said
method comprising the steps of:
providing a carrier substrate having first and second surfaces;
applying at least one metallic region to at least a portion of said first surface of said
carrier substrate;
providing a release coated carrier film, said release coated carrier film having at least
one metallic foil region disposed thereon;
providing at least one magnetic region disposed on at least one of either said carrier
substrate or said release coated carrier film; and
contacting said carrier substrate to said release coated carrier film such that said at
least one magnetic region is enclosed between said carrier substrate and said at least one
metallic foil region disposed on at least a portion of said release coated carrier film after said
carrier substrate and said release coated carrier film are contacted under conditions that serve
to bond the metallic and magnetic regions together.
The item or article to which the security device is attached
can be any article susceptible to counterfeiting or reproduction.
In one example, the security device is used with security papers
including, but not limited to, bank notes, checks, money orders,
passports, visas, titles, registrations, licenses, original
documents, certificates of authenticity, and gift certificates.
In another example, the security device is used with tickets
including, but not limited to, lottery tickets, event tickets and
transit tickets. In-a further example, the security device can
be used with labels or packaging materials including, but not
limited to, collars, (heat-shrink, glued, etc.), labels (pressure-
sensitive, glued, woven, in-mold), tear-tapes, overwrap, and
inserts. In yet a further example, the security element 10 is
used in laminated items including, but not limited to, ID cards,
badges, passports, credit/debit cards, immigration documents,
access cards, licenses, and credentials. The present invention
also contemplates using the security device in woven textile
materials, molded plastics, glass laminates, tamper-evident
devices, and decals.
In this manner, security devices such as security "threads"
with encoded or encodable magnetic regions can be decoded and
authenticated only by a machine programmed to locate and read the
encoded magnetic media. The magnetic region or media is thus not
visually discernible, and therefore much less subject to decodinq
and duplication by unauthorized sources.
The use of a metalized foil (typically initially provided on
a carrier substrate, such as a polyester, with a release layer
allowing the foil to be transferred to the security device), as a
camouflaging element in a security device, such as a security
thread, is provided due to the fact that foil exhibits excellent
light blocking, light reflecting and opacity capabilities per unit
thickness, making it a superb material to utilize in such an
application. In addition, the use of foil and foi] transfer
methods provides a process that is easy to implement and integrate
in the process of manufacturing security devices.
In one embodiment, the method starts by providing a security
film or base in the form of a polyester carrier substrate with or
without; visual indicia although typically, the security film will
include visual indicia. The visual indicia preferably includes an
imaged metallic layer including both metalized and demetalized
regions. The imaged metallic layer can be created using
techniques well known in the art including demetali2ation
techniques, the printing of metalized images or other indicia or
the provision of a foil (metalized) layer.
In one embodiment, an adhesive material is applied over one
entire surface of the imaged metallic layer. A foil film is next
provided. The foil film includes a carrier layer of a polyester
material approximately .0005 inches thick having a release lining
on at least one side. Applied to the release lining side of the
carrier layer is a thin aluminum or other metalized layer.
In one embodiment, one or more magnetic regions, in the form
of magnetic slurry media or other similar substance, are applied
over the entire bottom surface of the foil film although the
magnetic slurry can alternatively or additionally be selectively
applied to the foil film such as by printing using magnetic inks.
The select ive application of the magnetic media will generally
coincide with the metallic of foil regions provided on the base or
carrier substrate to fully enclose and camouflage the magnetic
regions. In another embodiment, the magnetic regions may not
coincide with the metallic regions and may be covered only on one
side by the foil film.
Next, the foil film and the security device with imaged
metallic layer are bonded under heat and pressure. A heated flat/
patterned or rotary die causes transfer of the foil layer with or
without an applied magnetic layer or region to the base security
device. The magnetic area can be encoded while the foil aluminum
region covers the magnetic region at least on one side thereby
preventing visual detection and decoding.
Tn another embodiment, the magnetic region(s) may be applied
to one surface (the top surface) of the security device and the
foil applied over only the magnetic region (s) or over the entire
surface of the security device.
Thus, a security device with a buried magnetic code, which is
invisible to the naked eye at least from one side, is produced.
In another embodiment, a security device with an imaged
metallic layer, as previously described, is provided. In this
embodiment, a foil film on which has been applied stripes of
magnetic media across the width of the foil film is provided. The
foil film is generally constructed of an aluminum or other
metallic layer applied over a release lining and a polyester
carrier substrate.
In this embodiment, a planar, heated die is provided which
transfers the stripes of magnetically encodable material and an
aluminum or other metallic covering to the security device, thus
forming a security device or a thread having stripes of
magnetically encodable material which are covered or camouflaged
from the naked eye beneath a metallic (foil) layer,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention features a method of producing a
security device using foil transfer techniques, which camouflages
(at least on one side) or buries magnetic or other opaque machine
readable information within the security device without making it
visible to the naked eye (at least from one side) . The terms
opaque machine readable information or magnetically encodable
material or magnetic area, as used herein, are intended to mean
indicia comprising or formed by any machine testable, inherently
colored material that is generally impervious to the passage of
light.
Although the present invention utilizes well known techniques
for bonding two films together using heated dies, the present
invention features a novel method for producing a security device
having buried or camouflaged encodable magnetic regions which are
nonapparent to the naked eye and which are thin enough to be used
in negotiable instruments or other devices including paper
currency or other uses where the possibility of counterfeit is
high.
In a first embodiment of the present invention, a security
device 10, FIG. 1A, including a top surface having an imaged
metallic layer 12 having one or more metalized regions 14 and non-
metalized regions 16 is provided. Optional areas of metallization
are shown at 14a. The imaged metallic layer 12 is applied over a
generally clear polyester carrier substrate 18 typically having a
thickness of approximately .0005 inches, as is well known in the
art. Further, the imaged metallic layer 12 may be made by one or
more well-known technique including demetalization or
conventional, gravure or screen printing techniques including an
imaged metallic layer including metallic and nonmetallic regions.
In accordance with the preferred embodiment, a foil film
layer 20 comprised of a polyester carrier substrate 22 and a
metallic foil region (such as aluminum) 24 is provided. In one
embodiment, and one or more magnetic stripes or regions 26 is also
provided although the entire foil film layer 20 may be flood
coated with a magnetic layer. In one embodiment, a layer of
adhesive 28 is applied over the aluminum region 24 and/or the
magnetic regions 2 6 to bond with the security device layer 10 as
would be described further below. The adhesive layer 28 is
preferably an adhesive of the heat sealable type available from
National Starch Company. Alternatively, the magnetic regions may
include, as part of their formulation, a heat or pressure
activated adhesive in which case the adhesive layer will not
physically be present will be functionally present as part of the
composition of the magnetic layer/region(s) 26.
In this embodiment, the foil film carrier substrate 22
includes a release layer at the interface between the polyester
carrier 22 and the foiled film layer 24. The polyester carrier
substrate layer 22 is generally approximately .000b inches thick.
The aluminum metal layer 24 is provided on a polyester
carrier substrate 22 and is approximately 200 Angstroms thick,
while the magnetic encoded regions 26, in this embodiment, are
applied to the foil film layer 20 using conventional, screen or
gravure printing techniques. The magnetic regions 26 are
approximately 1-20 microtis thick.
Once the two films have been provided and film registration
has been accounted for (as is generally well known in the art) ,
the two films are fused or bonded together utilizing pairs of
heated dies 30a and 30b which transfer the metallic layer 24 and
magnetic regions 26 to the underlying security device 10, FIG. ID
;in those areas of the heated die, resulting in the structure shown
in FIG. IB including one or more magnetic regions 2 6 over which is
disposed a metallic layer 24 in the form of a foil film, which
camouflages or hides the magnetic regions 26, at least from one
side, from the naked eye, while allowing the magnetic regions 26
to be magnetically encoded and decoded (providing machine
readability) to achieve authentication.
With the present invention, a security device having a
thickness of between 25 microns and 35 microns is provided which
is well within the specification of .040 inches for most security
threads or devices, as compared to the prior art of printing
magnetic bars covered by silver ink of the like which results in a
significantly thicker security device which is not usable in many
processes in use today such as in paper to be used for currency
and the like.
In another embodiment of the present invention, the method
starts by providing a security device 30, Fig. 2A, including a
polyester carrier substrate 32 over which is provided an imaged
metallic layer 34 comprising metalized regions 36 as well as non-
metalized regions 38. in one embodiment, a layer of adhesive 40,
such as a heat sealable adhesive available from National Starch
Company is applied over the imaged metallic layer 34 to provide
bonding with the magnetic region 56 of the foiled film layer 50 as
will be explained below. Alternatively, as previously disclosed,
the magnetic layer 56 may be a composite layer including a heat
and/or pressure activatable adhesive.
A foil film layer 50 is provided including a polyester
carrier substrate and release layer 52 over which is applied an
aluminum or other metalized layer 54, A magnetic layer 5 6 is
applied as a slurry or other coating over the entire bottom
surface of the foil film 50 over the metallic layer 54.
In order to bond the foiled film 50 with the security device
30, a heated, patterned die 60 is used in connection with heated
die 62 using conventional foil transfer techniques to provide the
structure 70, FIG. 2B, including magnetic regions 72a-72c covered
by metallic foil regions 54 corresponding to those regions 74 of
heated, patterned die 60 which engage with the mating unpatterned
heated die 62, to form a security device 70 having camouflaged or
invisible magnetically encodable regions 72 covered by metallic
foil regions 54.
In accordance with the teachings of the present invention, a
magnetic/metallic security device 100, FIG. 3, is provided. The
magnetic/metallic security device provided and fabricated in
accordance with the present invention includes one or more regions
102 in accordance with the present invention which include a
magnetic security feature embedded or camouflaged within the
security device 100.
In one embodiment of the present invention, the region 102a,
Which includes the magnetic region camouflaged within metallic and
foil regions, may have no visible indicia. Such an area may be a
narrow strip across the width of the security device 100, as shown
at 102a, or alternatively, may be a long area extending down the
length of the security device 100. In another embodiment, the
area 102b including a magnetic region embedded within the security
device and camouflaged by a metallic/foil layer may include, on
the surface, visual indicia 104 such as a picture, hologram or
other similar graphic indicia printed on the surface of the
security device 100 or provided as a defractive image or
detractive foil layer wherein the top surface of the foil layer
includes defractive indicia or image such as a hologram.
The term "defractive" as used herein generally means or
refers to a predetermined frequency shifting property that acts as
an authenticating feature so that the security device 120 itself
can be further authenticated, as will be described in greater
detail below.
One embodiment of the defractive indicia 104 includes a
frequency shifting additive, such as a pigment in ink used to
create an image, disposed on or contained within at least a top
surface of the foil film. 130. The frequency shifting additive has
the predetermined frequency shifting property that, is detectable
to authenticate the security device 10. for example, when
excitation radiation having a predetermined excitation frequency
excites the frequency shifting additive on the security device
120, the additive will emit radiation having a different
predetermined emitted frequency. The security device is
authenticated if the predetermined excitation frequency is emitted
at the predetermined emitted frequency, thus confirming the
predetermined frequency shiftinq property of the security device
10.
The excitation frequency and emitted frequency preferably
have narrow bands such that the security element 10 is
authenticated only for specific excitation/emitted frequencies.
The frequency shifting additive can shift the radiation either up
or down within the same spectral region, such as ultraviolet (UV) ,
visible, or infrared (IR) spectral regions, or between different
spectral regions. The frequency shifting additives also
preferably have an excitation frequency and/or emitted frequency
within the infrared spectral region or other non-visible spectral
regions to provide a covert security device 120. However, the
present invention also contemplates frequency shifting within the
JV and visible spectrums. Some examples of the frequency shifting
include UV to visible, visible to visible (hologram, for example),
visible to IR, IR to visible, and IR to IR.
In yet another embodiment, the magnetic region, enclosed by
metallic/foil regions may be in substantially identical
registration and together form visual indicia 106, such as the
letter "E".
In yet another embodiment, the magnetic and metallic layers
may be in substantially identical registration and form recesses
108, the recesses forming the visual indicia. This type of visual
indicia is often referred to as "clear text". In addition, one ox-
more regions 110 may omit any metallic or magnetic material, and
thus, serve as breaks in the metallic and/or magnetic regions.
These areas may extend fully or partially across the entire width
of the security device 100.
FIG. 4 represents a cross-section 120 (not to scale) of
security device 100 taken along arrows A-A, B-B, C-C or D-D. The
cross-section 120 includes a first or base carrier substrate 122
over which has been provided a metallic layer 124. As is well
known in the art, the metallic layer may be provided on the
carrier substrate 122 by a number of methods which are well known
to those skilled in the art.
The next two layers can be interchanged depending on the
method used to fabricate the security device of the present
invention. Layers 126 and 128 represent a magnetic layer and an
optional adhesive layer. As will be explained in greater detail
below, depending on which substrate the magnetic region is applied
to and if the magnetic region includes an adhesive component will
determine if and where the adhesive layer is provided.
The foil/metallic layer 130 is disposed on top of the
magnetic region, thus embedding the magnetic region between the
metallic layer 124 and the foil layer 130. The foil layer is
applied using a heated die which may either flat, patterned or
rotary, and is previously attached to a second polyester carrier
substrate 132 on which has been disposed a release layer 134 which
allows the carrier substrate 132 to be separated from the foil
layer 130, leaving the foil layer behind.
In one embodiment shown in the cross-section 140, FIG. 5A,
the magnetic region 126 is disposed on the first carrier substrate
122, which has been previously covered in whole or in part by
metallic layer 124 . An adhesive 128 is applied to foil 130 prior
to bonding. In yet an alternate fabrication method for this
embodiment, an adhesive 128 may be applied on top of the first
carrier substrate 122. In yet another embodiment, the method of
manufacturing such a security device may include placing an
adhesive layer on both the first carrier substrate 122 over the
magnetic region 126 as well as on the foil layer 130.
In yet another embodiment shown in cross-section 150, FIG.
5B, the magnetic region 126 and adhesive 128 maybe applied, by
methods well-known to those skilled in the art including surface
flooding, printing of magnetic media, or otherwise, directly onto
foil 130 prior to bonding carrier substrate 122 with £he metallic
layer 124 to the foil film 130 including the magnetic region 126.
Thus, according to the present invention, novel method is
disclosed for fabricating a novel security device having a
magnetic region embedded between metallic and foil layers. The
method, which is shown by a flow chart in Fig. 6 of the drawings, by method steps 200, 202,
204, 206, 208, starts by providing a first carrier substrate. Next, at least one surface of
the carrier substrate is metalized using well-known techniques. A foil film is
also provided,--------. which prior to bonding, is generally
provided on a polyester carrier substrate with a release layer Lo
facilitate releasing of the foil film from the carrier substrate.
At least one magnetic region is placed on either the first
carrier substrate and/or the foil film. ----------- Without
departing from the spirit of the present invention, a magnetic
region or material could be provided on either or both of the
first carrier substrate or the foil film. Additionally, the
magnetic region or material may be selectively applied, with or
without consideration of selectively applied metallic regions, or
applied over the entire surface of the foil or the first carrier
substrate layer. Finally, the foil film and the first carrier
substrate are bonded together at least in the area of the magnetic
material,-------• by a process using heat and pressure such as
provided by a set of heated dies. One or the other set of heated
dies may be flat or patterned. Alternatively, a rotary die set,
as is well known in the art, may also be utilized.
Accordingly, the present invention has provided a novel
security device which camouflages, at least on one side,
magnetically encodable material utilizing a foil film, thus
camouflaging the magnetic regions, which can be encoded and
subsequently decoded to prevent or at least thwart potential
counterfeiters from discovering their presence, decoding the
information and successfully counterfeiting the device to which'
the object or item which the security device is intended to
protect.
Modifications and substitutions by one ordinary skill in the
art are considered to be within the scope of the present
invention which is not to be limited expect by the claims which
follow.
