The invention relates to a single- or multilayer, oriented, film coated
with an aminosilane compound and composed of 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 producing
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.
