Abstract
The invention relates to security features, preferably connectors, for instance tax seals, labels, closures of blister packages and integral markings for connecting seams of products or product packages for identifying the genuineness of products. The security features in accordance with the invention are made up of several different components, encoding means and electrically conductive layers connected to a support substrate in various arrangements. Layers of electrically conductive polymers known per se are being used. The security features constitute insurmountable obstacles for forgers.
Claims23
Security features, preferably connectors (1, 22, 33) like labels, tax seals, closures for blister packages and integral markings for connecting seams (8) of products or product packages for identifying the genuineness of products (3, 4, 6, 7), consisting of substrates (10), integral and scattered metalized applications (13) of a defined surface resistance and electrically conductive polymers (12) of a defined surface resistance, the difference between the surface resistances being greater than 100 kΩ/□ and the connectors (1, 22, 33) being connected with products (3, 4, 6, 7).
The security features of one or more of the preceding claims, characterized by the fact that electrically conductive polymers (12), integral or scattered metalized applications (13), substrates (10), protective layers (14) and primers (11) are selective arranged as encoding means.
The security features of one or more of the preceding claims, characterized by the fact that the encoding means are provided with electrical and/or optical and/or magnetic functionalities.
The security features of one or more of the preceding claims, characterized by the fact that the electrically conductive polymers (12) are applied sectionally or surface-modulatingly or sectionally surface-modulatingly.
The security features of one or more of the preceding claims, characterized by the fact that the surface resistance of the electrically conductive polymers (12) constitutes a readable code, particularly detectable by capacitive coupling.
The security features of one or more of the preceding claims, characterized by the fact that the integral or scattered metalized applications (13) are applied sectionally, surface-modulatingly or sectionally-surface-modulatingly.
The security features of one or more of the preceding claims, characterized by the fact that the surface resistance of the integral or scattered metalized applications constitutes a readable code, particularly detectable by capacitive coupling.
The security features of one or more of the preceding claims, characterized by the fact that the encoding means may be affected physically or chemically.
The security features of one or more of the preceding claims, characterized by the fact that as security characteristics the encoding means react by application of energy, in particular visible light, UV, IR, or heat radiation in the connectors (1, 22, 33) and/or during joining with the products (3, 4, 6, 7).
The security features of one or more of the preceding claims, characterized by the fact that the encoding means consist of components of a reaction dye and that they react only when the components contact each other.
The security features of one or more of the preceding claims, characterized by the fact that the primer (11) is applied sectionally of surface-modulatingly.
The security features of one or more of the preceding claims, characterized by the fact that the electrically conductive polymer (12) is a polyethylene dioxythiophene polystyrene sulfonate.
