A method for the production of a multi-layer identity card of plastic. The card to be produced comprises at least one card core layer printed on at least one side and on the printed side of the card core layer, a covering layer is applied.

Method for the production of a multi-layer identity card of plastic

An improvement applicable to a method for the production of a multi-layer identity card of plastic wherein the card comprises one or more card core layers bonded under the action of pressure and heat and printed on either side or on opposite sides with a covering layer applied to the printed side or sides of the card core. In accordance with the improvement a thermoplastic polymer adhesive is applied between and in direct contact with each covering layer and the respective printed side of the card core, the thermoplastic adhesive coating possessing at least one additive that increases the friction between the covering layer and the printed card core during lamination so as to prevent displacement of the printed card core in relation to the covering layer or layers.

Method for the production of a multi-layer plastic identity card

The invention relates to an adhesive joint which connects a body made of a first material to a plastic body. The adhesive joint is formed by an adhesive laminate which includes a flexible core layer made of acrylate and outer layers made of hot-melt adhesive which respectively adjoin the first body and the plastic body, and a transition layer is respectively arranged between the outer layers and the core layer.
