A process for producing a polycarbonate-layer composite

The invention relates to a method for producing a composite having at least a first polymer layer and a second polymer layer each made of a polycarbonate polymer based on bisphenol A, wherein an intermediate layer is disposed between the first polymer layer and second polymer layer, comprising the following steps: a) In at least a portion of the first polymer layer, the intermediate layer is applied, b) optionally the intermediate layer is dried, c) the first polymer layer is on the side on which the intermediate layer is arranged, with a liquid preparation containing a solvent or a solvent mixture, and a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenyl cycloalkane, coated, the preparation covering the intermediate layer, d) optionally followed by a drying process step e) is carried out in step c) subsequent to step c) or step d), the second Polym erschicht on the first polymer layer, covering the intermediate layer, placed, f) the first polymer layer and the second polymer layer are laminated together under pressure at a temperature of 120 ° C to 230 ° C and for a defined period of time.
