<p>The invention relates to a process for the preparation of articles with a three-dimensional surface structure, in which a substrate is printed, at least one of the printing inks employed for the printing being varnish-repellent, and the printed substrate is then varnished. In accordance with the invention, the printed substrate is varnished with a radiation-curable varnish which contains no amino resin and comprises A) from 18 to 99.9% by weight of an epoxy acrylate, a polyether acrylate or a polyester acrylate, B) from 0.1 to 5.0% by weight of a Br+E,uml o+EE nsted acid or an acid anhydride, C) from 0 [sic] to 12% by weight of a photoinitiator, D) from 0 to 40% by weight of water or at least one organic solvent, E) from 0 [sic] to 10% by weight of a polyol which may be ethoxylated and/or propoxylated and has from 2 to 50 carbon atoms in the molecule, and F) from 0 [sic] to 30% by weight of other auxiliaries and additives, and the varnish coat applied is cured with high-energy radiation.</p> |
