Method for producing a multilayer data carrier and data carrier produced by said method
Abstract:
The invention relates to a method for producing a multilayer data carrier comprising a first layer which is made of plastic and has an upper face on which an opaque layer partially covering said upper face, for example a metal layer, is arranged. The data carrier has a second layer made of plastic which is disposed on the first layer and is transparent at least in a sub-region of the metal layer. The metal layer is partially removed by a laser to such an extent that the metal layer has at least one break. The metal layer is preferably laminated between the first and the second plastic layers.
