Abstract:
The invention relates to layer structures for ID cards on which information can be written by laser engraving and which have an additional layer that is applied to the card body after the laser engraving and restricts or completely prevents subsequent writing on the card by means of laser engraving, and consequently prevents falsification of the identifying information contained, and relates to a method for blocking the laser engraving writability of layer structures on which information can be written by laser engraving.
Abstract:
The present invention relates to a layer structure having improved properties for laser engraving, to particular embodiments of said layer structures in the form of co-extrusion films, and to security documents, preferably identification documents having said layer structures.
Abstract:
A method of making a plastic molding is disclosed. The multi-step method entails applying a metallic layer 20 to 150 nm thick to a translucent plastic film having a thickness of 50 to 750 μm, removing part of the metallic layer, and applying to the metallized side of the film an adhesive layer 5 to 50 μm in thickness to obtain a product, and injection molding the product with a translucent thermoplastic. The plastic molding thus made is suitable for the preparation of keys, fittings, trim strips, reflectors, keyboards, casings, shields, advertising panels and packaging items and identification cards.
Abstract:
The invention relates to a security and/or valuable document containing a scratch-resistant coating obtained from a lacquer composition comprising I) from 12 to 70 parts by wt. of a C2-C12-diol diacrylate or C2-C12-diol dimethacrylate, II) from 12 to 40 parts by wt. of an alkoxylated mono-, di-, tri-, tetra-, penta- or hexaacrylate or alkoxylated mono-, di-, tri-, tetra-, penta- or hexamethacrylate, III) from 0 to 40 parts by wt. of a monomer selected from the group consisting of pentaerythritol triacrylate, pentaerythritol tetraacrylate, dipentaerythritol tetraacrylate, dipentaerythritol pentaacrylate, dipentaerythritol hexaacrylate, pentaerythritol trimethacrylate, pentaerythritol tetramethacrylate, dipentaerythritol tetramethacrylate, dipentaerythritol pentamethacrylate, dipentaerythritol hexamethacrylate, reaction products thereof with aliphatic or aromatic diisocyanates, and mixtures thereof, IV) from 5 to 60 parts by wt. of a further mono-, di- or triacrylate or mono-, di- or trimethacrylate, and further comprises V) from 0.1 to 10 parts by wt. of a photoinitiator.
