Abstract:

Carbonyl-containing polymer films, such as PET, are selectively metallized by contacting the films with a layer or film of metal, such as aluminum, and then irradiating selected portions of the surface of the film with infrared radiation thereby heating those selected portions of the film. The metal on or opposite the irradiated portions of the surface adhere to the film. The remaining metal may be readily removed. The process provides surprisingly good spatial resolution. The present process is particularly useful in the production of microcontacts for circuit boards.
