The invention relates to a multilayer, oriented film, in which at least
one layer comprises a polyester which comprises an additive which, on
irradiation with electromagnetic radiation, forms metal nuclei on which
further metal can be deposited in further steps of the process. The
invention further relates to a process for the production of this film
and to its use in printed circuit boards, ribbon cables, smart cards,
RFID labels, membrane keyboards, and film-based circuits of any type.
