Abstract
Abstract A security token, such as a bank note or identity card, comprises a sheet-like substrate made up from film of transparent bi-axially oriented polymer coated with layers of opaque and heat activated adhesive material. The opaque layer is applied in such a way as to leave a transparent area for inspection of a security device, for example, a diffraction grating, incorporated in the polymer film. The substrate may bear printed or other identifying indicia and is protected with an intimately bonded layer of transparent polymeric material.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
65 words
A token comprising a flexible film substrate bearing identifying indicia and including an optically variable security device, characterised in that the substrate comprises a transparent bi-axially-oriented polymeric film composite having a heat-activated adhesive coating and an opacifying coating on at least one side, said substrate, indicia and the security device being covered with a transparent protective layer of polymeric material intimately heat-bonded to the substrate.
Claim 2
Dependent Claim
65 words
A token comprising a flexible film substrate bearing identifying indicia and including an optically variable security device, characterised in that the substrate comprises a transparent bi-axially-oriented polymeric film composite having a heat-activated adhesive coating and an opacifying coating on at least one side, said substrate, indicia and the security device being covered with a transparent protective layer of polymeric material intimately heat-bonded to the substrate.
Claim 3
Dependent Claim
39 words
A token according to claim 1 further characterised in that the substrate itself comprises a laminate of two or more layers of transparent bi-axially-oriented polymer film each of which is coated on each side with a heat-activated adhesive layer.
Claim 4
Dependent Claim
37 words
A token according to claim 1, further characterised in that an opacifying coating is applied to both sides of the substrate and comprises a major proportion of pigment and a minor proportion of a cross-linked polymeric binder.
Claim 5
Dependent Claim
69 words
A token according to claim 1, further characterised in that: (a) the substrate itself comprises a laminate of two or more layers of transparent bi-axially-oriented polymer film each of which is coated on each side with a heat-activated adhesive layer; and (b) an opacifying coating is applied to both sides of the substrate and comprises a major proportion of pigment and a minor proportion of a cross-linked polymeric binder.
Claim 6
Dependent Claim
27 words
A token according to claim 1, further characterised in that the opacifying coating is applied so as to leave an area of the substrate uncoated and transparent.
Claim 7
Dependent Claim
27 words
A token according to claim 2, further characterised in that the opacifying coating is applied so as to leave an area of the substrate uncoated and transparent.
Claim 8
Dependent Claim
27 words
A token according to claim 3, further characterised in that the opacifying coating is applied so as to leave an area of the substrate uncoated and transparent.
Claim 9
Dependent Claim
27 words
A token according to claim 4, further characterised in that the opacifying coating is applied so as to leave an area of the substrate uncoated and transparent.
Claim 10
Dependent Claim
21 words
A token according to claim 5, characterised in that the security device is heat-bonded to the substrate in said transparent area.
Claim 11
Dependent Claim
21 words
A token according to claim 6, characterised in that the security device is heat-bonded to the substrate in said transparent area.
Claim 12
Dependent Claim
21 words
A token according to claim 7, characterised in that the security device is heat-bonded to the substrate in said transparent area.
Claim 13
Dependent Claim
21 words
A token according to claim 8, characterised in that the security device is heat-bonded to the substrate in said transparent area.
