<p>Security- and/or valuable document comprises at least a scratch-resistant coating, which is prepared from a coating composition comprising (i) 2-70 parts by weight of at least one 2-12C diol diacrylate or 2-12C diol dimethacrylate, (ii) 12-40 parts by weight of at least one alkoxylated, preferably ethoxylated mono-, di-, tri-, tetra-, penta or hexaacrylate, (iii) 0-40 parts by weight of at least one monomer, (iv) 5-60 parts by weight of at least one additional mono-, di- or triacrylate or mono-, di- or trimethacrylate, and (v) 0.1-10 parts by weight of at least one photoinitiator. Security- and/or valuable document comprises at least a scratch-resistant coating, which is prepared from a coating composition comprising (i) 2-70 parts by weight of at least one 2-12C diol diacrylate or 2-12C diol dimethacrylate, where 2-12C is a linear alkylene residue, which may be optionally substituted with a methyl group or interrupted by at least one oxygen atom and optionally substituted with at least one methyl group, (ii) 12-40 parts by weight of at least one alkoxylated, preferably ethoxylated mono-, di-, tri-, tetra-, penta or hexaacrylate or alkoxylated, preferably ethoxylated mono-, di-, tri-, tetra-, penta- or hexamethacrylate, (iii) 0-40 parts by weight of at least one monomer comprising pentaerythritol triacrylate, pentaerythritol tetraacrylate, dipentaerythritol tetraacrylate, dipentaerythritol pentaacrylate, dipentaerythritol hexaacrylate, pentaerythritol trimethacrylate, pentaerythritol tetramethacrylate, dipentaerythritol tetramethacrylate, dipentaerythritol pentamethacrylate, dipentaerythritol hexamethacrylate or their reaction products with aliphatic or aromatic diisocyanates, (iv) 5-60 parts by weight of at least one other mono-, di- or triacrylate or mono-, di- or trimethacrylate, where parts by weight of components (i)-(iv) is added up to 100 parts by weight, and (v) 0.1-10 parts by weight of at least one photoinitiator, which is added to 100 parts by weight of the components (i)-(iv). Independent claims are also included for: (1) producing the security- and/or valuable document comprising forming a film stack containing many thermoplastic plastic films and laminating, where the film stack comprises at least one thermoplastic polymer film with an outwardly oriented, scratch-resistant coating side for the production of at least one scratch-resistant outer layer of security- and/or valuable document, and the scratch-resistant coating made of these thermoplastic plastic film is produced from the coating composition; and (2) the thermoplastic film comprising at least one coating prepared from the coating composition.</p> |
