Description

technical field

[0001] The invention relates to a security paper for the production of notes of value, which security paper has an optically variable security element and an ink-receiving layer (Farbannahmeschicht) with depressions, and to a security paper for the production of such a security paper A method and a device for implementing the manufacturing method, and a value note made of the anti-counterfeiting paper. Background technique

[0002] Documents of value within the scope of the invention are, for example, banknotes, stocks, bonds, certificates, receipts, cheques, lottery tickets, high-value tickets, passports, identity cards, credit cards and other flat items of value. But these items of value can also be packaging for possibly high-end products. The security paper concept includes within the scope of the present invention these documents of value, for example, in their pre-negotiable stages. The security paper can here be present in almost continuous form and ...

Embodiment Construction

[0044] exist figure 1 In the figure, a bank note 1 is shown as a document of value, which has a windowed security thread 2 as an optically variable security element. The security thread 2 has a strip width of 3 to 5 mm and, due to register fluctuations, is located at any position within the so-called swing region 3 with a strip width of about 1 cm.

[0045] exist figure 2 A first embodiment of the security paper 7 is shown along the figure 1 The cross-section of the A-A` section line in the middle, the anti-counterfeiting paper 7 is used to manufacture such as figure 1 The film composite banknote 1 is shown. The base layer 8 of the anti-counterfeiting paper 7 includes the middle paper layer 4 and the transparent PET film 5 attached on both sides. Furthermore, a security thread 2 is shown which, in the sectional view shown (along the line A-A'), has just reached the surface of the paper layer 4 and is therefore figure 2 The anti-counterfeiting paper 7 o'clock in can be s...
