Abstract (en)

[origin: EP0391578A1] A process for producing a two phase metal/oxide film. The process comprises forming a porous oxide film (10) on a substrate (11), introducing a weakened stratum (12) into the oxide film so that the film (10) (or at least an outer part of the film) can be subsequently detached along the weakened stratum, depositing a metal (13, 14) on and/or within the pores of the film, and detaching at least the outer film part from the substrate. The detached film so produced can be used for many purposes depending on the film thickness, position of the metal deposits on or with the pores etc. Examples include optical interference devices, magnetic media, coatings for plastics and paper, etc.
