Claim:
A multiple layer identity card of plastic formed by a method comprising: applying at least one card core layer ( 1 A) having at least one adhesive coating ( 1 A 0 ) on one side and on which a printed layer ( 1 A 1 ) is located, applying a further adhesive coating ( 1 B 0 ) between the printed layer ( 1 A 1 ) and a covering layer ( 1 B), and bonding the card core layer ( 1 A), printed layer ( 1 A 1 ), and covering layer ( 1 B) by the adhesive coatings ( 1 A 0 and 1 B 0 ) under the action of pressure and sufficient heat to laminate the assembly, characterized in that the adhesive coatings ( 1 A 0 and 1 B 0 ) comprise at least one additive (Z) in solid, insoluble form in the coating selected from the group consisting of silica (SiO 2 ), a friction causing silicate, and calcium carbonate (CaCO 3 ), such as to cause friction between the covering layer ( 1 B) and the printed card core ( 1 A) during lamination.
