The invention further relates to multi-layer products having at least three layers, comprising a substrate layer made of a substrate and containing special copolycarbonates, a metal layer and at least one additional layer.
Claims14
A process for producing a multilayer structure, comprising processing a substrate material comprising a copolycarbonate which comprises at least one bisphenol unit of formula (2)
- in which
- R2 comprises C1-C4-alkyl,
- n is 0, 1, 2, or 3,
- and comprises as terminal group chain terminator, a structural unit of formula (1)
- in which
- R1 are hydrogen or C1-C18-alkyl,
- and has a Vicat softening point in accordance with DIN ISO 306 above 160° C.,
- to give a molding,
- and pretreating said molding with an air- or argon-based plasma and then metalizing by a sputtering process in a DC magnetron.
