<p><P>PROBLEM TO BE SOLVED: To provide a film-like light waveguide superior in curvature durability and electrification prevention. <P>SOLUTION: The film-like light waveguide has: a lower clad layer 10, a core part 18, and an upper clad layer 20; and electrification preventive layers 8, 22 on one or more surfaces of the lower clad layer 10 and the upper clad layer 20. The electrification preventive layers 8, 22 are a cured material of a composition containing (A) urethane (meta)acrylate oligomer, (B) a monomer having one or more (meta)acryloyl group in molecules, (C) an optical radical polymerization initiator, and (D) an electrification preventive agent. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
