Abstract

A laminated multi-layer identification card comprising a plurality of individual layers connected to one another and having at least one outer surface which is directly contactable. At least one additional outer layer is laminated to the outer surface and covers a portion of the outer surface. The outer layer has a surface relief pattern in the form of intaglio printing which is directly accessible. The outer laminated layer may be made of paper and the remaining exposed outer surface not covered by the outer layer may be given a texture similar to that of paper so that the entire surface of the card feels like a paper-rough surface.
