Abstract
The invention concerns a security and/or value document, in particular a banknote. The security and/or value document has a support (1) of a paper material and an in particular strip-form or thread-form film element (2) which contains one or more optical security features. The support (1) has one or more window-shaped openings (35) which are closed by means of the film element (2) which projects beyond the openings on all sides. Applied to the side of the support (1) of a paper material, which is in opposite relationship to the film element (2), is a sealing layer (4) which covers the surfaces of the film element (2) at least in the region of the openings.
Claims17
A security and/or valuable document comprising:
- a paper support,
- a film element which has one or more optical security features, and
- a sealing layer, wherein the support has at least one through-hole, the at least one through-hole being closed by means of the film element which projects beyond the at least one through-hole on all sides, the sealing layer covers the surface of the film element at least in the region of the at least one through-hole, the sealing layer being applied to the side of the support which is in opposite relationship to the film element, the sealing layer being formed from a lacquer layer, the lacquer layer being one that can be applied by at least one of printing, scattering, sprinkling and spraying, wherein a length expansion coefficient of the sealing layer differs from a length expansion coefficient of the film element by not more than 10% and/or a modulus of elasticity of the sealing layer differs from a modulus of elasticity of the film element by not more than 10%.
A security and/or valuable document, comprising:
- a paper support including at least one through-hole;
- a film element including at least one optical security feature, said film element covering said at least one through-hole and at least a portion of said support surrounding said at least one through-hole, said film element disposed on a first side of said support;
- and
- a sealing layer covering said at least one through-hole, said sealing layer disposed on a second side of said support opposed to said first side, wherein said sealing layer includes a lacquer, the lacquer being one that can be applied by at least one of printing, scattering, sprinkling and spraying, wherein an expansion coefficient of the sealing layer differs from an expansion coefficient of the film element by not more than 10% and/or a modulus of elasticity of the sealing layer differs by not more than 10% from a modulus of elasticity of the film element.
