Abstract

A method for preparing a tamperproof ID document comprising in order the steps of a) providing an ID document having at least one image on at least one outermost surface of said ID document; b) printing or coating a curable liquid on at least one of said outermost surfaces of said ID document thereby forming an outermost layer on said printed or coated outermost surface at least partially covering said at least one image; and c) curing said outermost layer; wherein said curable liquid comprises a polymerizable and/or a polymeric abherent agent and said printed or coated outermost surface is the surface of a layer or foil exclusive of porous pigment. Also disclosed is an ID document wherein the surface of an outermost layer at least partially covering an image on the ID document has a surface energy of less than 28 mN/m; and the use of an abherent agent-comprising curable composition to provide ID-documents with a substantially non-printable and substantially non-laminatable abhesive surface.
