Single-layer, oriented thermoplastic polyester film capable of structuring by means of electromagnetic radiation, for producing selectively metallized films

摘要

The invention relates to a single-layer, oriented polyester film where the polyester comprises an additive which on irradiation with electromagnetic radiation forms metal nuclei on which further metal can be accumulated during 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.
