Title:
POLYMER OPTICAL WAVEGUIDE FILM
Document Type and Number:
WIPO Patent Application WO/2003/058306
Kind Code:
A1
Abstract:
A polymer optical waveguide film comprising a core and clad both made of a polymeric material is characterized in that at least either the front or back side of the film is provided with a protective layer made of a polymeric material having a solvent−resistance higher than that of the clad. The clad is hardly scratched, and the polymer optical waveform film is excellent in solvent−resistance and does not crack even if the film is brought into contact with a general−purpose solvent such as acetone.
