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.
Claims24
A method for producing a multilayer data carrier, said data carrier comprising:
- a first layer of plastic that comprises an upper side;
- an opaque layer that is arranged on said upper side of said first layer and partially covering said upper side;
- and
- a second layer of plastic which is arranged on the first layer and is transparent at least in a subregion of the opaque layer, wherein said method comprises:
- the step of partially removing the opaque layer using a laser until the opaque layer has at least one recess, or
- the step of producing the opaque layer from a material which is modified during the exposure in such a way that it becomes transparent or at least translucent in the exposed region.
