| 摘要 |
A composition comprising a cyclic olefin addition copolymer containing recurring units of the following formulas (1) and (2),and at least one compound selected from (A) a compound acting as an acid when heated to 50° C. or higher, (B) a metal compound of an alkoxy compound, aryloxy compound, carboxyl compound, beta-diketone compound, halogen compound, or oxide, (C) an organic carboxylic acid, organic phosphoric acid, organic sulfonic acid, ammonia, primary to tertiary amine compound, or quaternary ammonium hydroxide compound. The composition exhibits excellent optical transparency, solvent resistance, dimensional stability, heat resistance, and adhesion to metals and inorganic materials, and suitable for use in optical transparent materials and electronic material parts, to a cross-linked product obtained by crosslinking the composition via siloxane bonds, and to a film, sheet, or coating made from the composition.
