The thermosetting crosslinked cyclic olefin resin film comprises (a) 100 parts by mass of a cyclic olefin monomer, (b) 100 to 20% by mass of a (meth) acrylic acid alkyl ester having an alkyl group having 3 or more carbon atoms, and an aromatic vinyl compound. Alternatively, it is a (co) polymer with 0 to 80% by mass of a (meth) acrylic acid alkyl ester having an alkyl group having 2 or less carbon atoms, and a (co) polymer 0.5 having a weight average molecular weight of 1,000 to 2,000,000. -8 parts by mass, (c) 0.3-8 parts by mass of a phenolic stabilizer having a hydrazine structure or an oxamide structure, (d) 0.5-10 parts by mass of a phosphorus stabilizer, and (e) a hindered amine light stabilizer. A polymerizable composition containing 0.5 to 10 parts by mass is obtained by ring-opening metathesis polymerization. |
