PURPOSE:To enable writing at an ultra-high speed by laminating a high-polymer film having small oxygen permeability on a photoreactive film consisting of a polymer contg. a specific ion pair charge transfer complex. CONSTITUTION:The high-polymer film 3 having the small oxygen permeability is laminated on the photoreactive film 2 consisting of the polymer contg. the ion pair charge transfer complex of the 4, 4'-bipyridinium ions obtd. by acting a donor on 4,4'-bipyridinium as an acceptor to form the ion pair charge transfer complex, by which the protection against oxidation is provided. The compd. forming the ion pair charge transfer complex with the 4,4'-bipyridinium ions includes, for example, tetraphenylborate having plural fluoro substd. The polymer incorporating the ion pair charge transfer complex includes, for example, poly(tetrahydrofuran) having 4,4'-bipyridinium groups in a part of the main chain or a vinyl polymer having the 4,4'-bipyridinium groups in the side chain, etc. |
