Abstract
A multilayer composite material having at least one layer of (co)polycarbonate is disclosed. The (co)polycarbonate contains as end groups phenolate groups of formula (1)
wherein R is selected from the group consisting of C10-C25-alkyl, C10-C25-alkoxy and C10-C25-alkyl-substituted aryl. The inventive composite material which may be transparent or colored, exhibits improved laminability and processability as compared with the prior art and may be laser-printable.
