TRANSPARENT POLYIMIDE SUBSTRATE AND METHOD FOR FABRICATING THE SAME

摘要

The present invention provides a transparent polyimide substrate comprising a transparent polyimide film and a cured layer of a polyisocyanate formed on at least one surface of the transparent polyimide film, the polyisocyanate containing an acrylate group and having 2 to 5 isocyanate groups per molecule. The transparent polyimide substrate has excellent scratch resistance, solvent resistance, optical properties and flexibility and low water permeability and is useful as a cover substrate for a flexible electronic device.
