<p>A polymeric laminated data carrying device (9), such as a card, having a core (11) and at least one overlay (15, 24) is disclosed. The device includes polyester, polyvinyl chloride and a polar adhesive. Preferably, the adhesive has functional groups therein. Preferred embodiments of the invention include an axially oriented polyester layer (20, 27) in each of two overlays (15, 24). Each of these polyester layers is included in the device of the invention in such a manner that the axial orientation of the polyester layer is substantially parallel to the axial orientation of the second polyester layer. The invention is also directed toward methods of making a polymeric laminated data carrying device, such as a card.</p> |
